Chapter 1: Introduction

Product Description

OverviewThe ACO-3901 Automatic Changeover Unit is a non-generic automatic changeover unit that supports two input sources: the MTG-3901 Master Time Generator or the CSD-3902 Clock System Driver. The ACO-3901 provides redundant switching between a primary MTG-3901, a secondary MTG-3901 and an external source (or between a primary CSD-3902, a secondary CSD-3902, and an external source).The switch from primary to secondary inputs can be isolated to a single channel or made globally to the other available channels. Faults in input signals are indicated through front panel LEDs and via an audible alarm, heard on a speaker located on the ACO-3901 front module.In the event of a power failure in the NEO frame, the ACO-3901 automatically switches to the external 24 volt source.

Main FeaturesThe ACO-3901 Automatic Changeover Unit has the following features:• Two sets of inputs from two MTG-3901 modules or two CSD-3902

modules• One set of inputs from an external source• Three-module construction, with a front module for active

electronics, a rear card for relays, and a back module for connectivity

• Single-channel or global switching• Automatic switching to backup sources• Automatic switching to 24 volt external power source in the event

of power loss• 24 V DC backup power supply unit• User-configurable fail condition for electrical (threshold) or

legitimate signal (audio, video)• Audio alarm in case of source or power failure• Self-generating failed source outputs error list visible on card-edge,

CCS software, and CCS control panels

2 ACO-3901 Installation and Operation Manual


• Ability to synchronize the two MTG-3901 modules (or two CSD-3902 modules) to the external source or to one another

• Ability to perform self-diagnosis (visible on the card-edge, on CCS control panels, and on CCS software applications)

• On-board self-testing for signal monitoring to detect component failure

• Control and monitoring via the card-edge, CCS software applications, and CCS control panels

Front, Rear, and Back Modules

Module AlignmentThe ACO-3901 module’s unique three-piece design includes a front module, an extended three-slot back module, and a rear module that bridges the front and back modules.Figure 1-1 on page 4 shows the alignment of the ACO-3901-FM front, the ACO-3901-RM rear, and the ACO-3901-BM back modules. Front, rear, and back modules are designated by the suffix “-FM”, “RM”, and “-BM” respectively. For example, the front module of the ACO-3901 is the “ACO-3901-FM”.See Figure 1-2 on page 5 for detailed labelling of the ACO-3901-BM back module.

Default Input on the ACO-3901-RMThe ACO-3901-RM rear module has a default input setting that will become active in the event of a source failure. All 18 jumpers located throughout the module must be set to either MTG/CSD 1 or ExtSrc as the default input. To prevent inadvertently disabling the functionality of the ACO-3901, the GlbMTG1Ext parameter must also be set to the same option. For example, if the jumpers are changed from MTG/CSD 1 to ExtSrc, the GlbMTG1Ext parameter must also be changed to ExtSrc. Similarly, if the GlbMTG1Ext parameter is changed from the default MTG/CSD 1 to ExtSrc, all 18 jumpers must be set accordingly.

Figure 2-4. ACO-3901-RM Rear Module

Follow this procedure to set the default input:1. Locate the 18 jumpers on the ACO-3901-RM module.



2. Place the jumper on pins 1 and 2 for External input (default setting), or pins 2 and 3 for MTG/CSD 1 input. See Figure 2-5.

Telco Line on the ACO-3901-BMThe ACO-3901-BM back module is capable of accepting one or two MTG-3901 (or CSD-3902) separate external inputs via the telco connector. Set the J1 and J2 jumpers to either Line 1 or Line 2. See Figure 2-6 for the location of the jumpers.• Line 1: The inner conductors are used and the two MTGs or CSDs

share the same telco line.• Line 2: The inner connectors are wired for the top MTG-3901 or

CSD-3902 module (MTG1), and the outer connectors are wired for the bottom MTG-3901 or CSD-3902 module (MTG2); each MTG or CSD module therefore has its own line.

Installing the ACO-3901 ModulesYou can insert any NEO module into its frame with the power supply turned on or off. Follow this procedure: 1. Remove three blank back modules from the frame (two on the left

side and one on the right side).Do not discard the blank back modules and their captive screws. You may need them for future configurations.

2. Match the connection ports and then join the ACO-3901-RM rear module to the ACO-3901-BM back module. (See Figure 2-8.)

Figure 2-8. Alignment of ACO-3901-FM and ACO-3901-RM/BM Modules

3. Attach the connected ACO-3901-RM/BM module to the two empty rear slots, using the mounting screws provided.Ensure that the EMI gaskets separating the back modules remain in place during the installation. The EMI gaskets fit tightly. To ease the installation of back modules, gradually press each back module into place from the left side to the right side.

4. Apply labels to the back module, if these are supplied separately.5. Write down the placement of the back modules in the diagrams

provided in Figure 2-9.

CautionTo prevent overheating during frame operation, keep the front panel closed and all back module slots covered.

NoteThe primary and backup sources must both be either MTG-3901s or CSD-3902s. Two different module types cannot be mixed.



Connecting the Input SourcesThe ACO-3901 is designed to accept inputs from one or two MTG-3901-FM front modules, or one or two CSD-3902-FM front modules—both of them adjacent to the ACO-3901 module. Also, it can accept another external source such as a CSD-3902 or MTG-3901 located elsewhere.

MTG-3901 ModulesThe ACO-3901-BM back module accepts either one or two MTG-3901-FM front modules, or one or two CSD-3902-FM front modules. To connect an MTG-3901-FM or CSD-3902-FM module to an ACO-3901-BM back module, follow this procedure:1. Open the front panel and allow it to hang freely from its hinges.2. Slide an MTG-3901 or CSD-3902 module into either one of the two

left slots beside the ACO-3901 module.Ensure that the module slides inside the module guides.

3. Push the module until it is seated properly.Make sure that the edge of the module is flush with the edge of the module guides.

4. Close the extractor handle.5. Install the second MTG-3901 or CSD-3902 following steps 1 to 4

above, and then make all the necessary rear connections.The module is now ready for testing.

6. Close the front panel to ensure proper frame ventilation.

External Input SourceYou can connect external sources (such as a CSD-3902 or an MTG-3901 located elsewhere) to the ACO-3901. The back module of the ACO-3901 accepts the following external sources:• Four unbalanced composite video sources, plus DARS and Hz• Balanced DB15 connector for timecode, GPI, and impulse drive

NoteThe CSD-3901 module is not compatible with the CSD-3902 module and cannot be used in an ACO-3901 configuration.

CautionDisconnect the telephone line cord when installing, removing or servicing the Master Time Generator module.



Connecting the External Power SupplyThe external power supply that connects to the ACO-3901-BMis a Class 2/LPS UL/CSA certified power supply, rated at 24 VDC 3A.

Figure 2-12. Location of the External Power Supply Connector on the ACO-3901-BM Module

Removing ACO-3901 ModulesAlthough the ACO-3901 package includes a wide back module and an additional rear module, the ACO-3901 requires no specialized removal procedures. For general information about removing NEO modules, see the NEO FR-3901, FR-3903, and FR-3923 Mounting Frames Installation and Operation Manual.

Upgrading ACO-3901 FirmwareFirmware upgrading is a routine procedure that you must perform to install newer versions of software on NEO modules. CCS Pilot, Co-Pilot, or Navigator software applications are required for this procedure. When performing the upgrading procedure, check the appropriate readme file to confirm which files are needed. Use care to ensure that you upload the correct files to the intended module.If for some reason the upgrade fails, the module may not respond to controls and will appear to be non-functional. In that event, follow the procedures described in “Correcting a Failed Upgrading Procedure” on page 28.

Upgrading ProcedureFollow these steps to upgrade the firmware:1. Download the most recent appropriate upgrade package from the

our Web site.2. If the affected module has not been discovered, perform the

Discovery operation, as described in your CCS software application manual or online help. (If you cannot discover the device, see “Discovering Devices Using the Drag-and-Drop Method” on page 26.)



3. From the Tools menu, select Software Upgrade. The Software Upgrade window opens or is brought to the foreground.

Figure 2-13. Software Upgrade Tool’s New Transfer Tab

4. On the New Transfer tab, click Add.The Device Selection dialog opens.

5. Select one or more devices, and then click OK to close the Add Device dialog box.You can only add one unit from each IP address. All items in a frame have the same IP address. The selected devices appear in the table on the New Transfer tab of the Software Upgrade window. This table lists devices that are to receive the same upgrade package.

Click here to access options for entering Telnet and FTP user name and password and creating automatic backups.

Package Info includes a list of the components contained in the ZIP file.



For each device in this table, you can highlight its position in the Tree View by clicking Find Device. You can check the software revision numbers, etc., by clicking Version Info, and create an automatic backup by clicking the Device Options... button. (Place a check beside Software Backup and enter a file name or click Browse to choose a new file location.)

6. Press Browse... to select the software upgrade package (ZIP file). A standard Windows File Selection dialog opens.

7. Choose the upgrade ZIP file on a local or network drive. The selected file’s path name is displayed in the edit box to the left of the Browse… button.The extraction process on the ZIP file is handled as part of the upgrade process. You do not need to extract the files yourself.

8. Press Submit Transfer... A dialog box opens, requesting confirmation that you want to proceed with the request. If you have multiple devices selected, multiple transfer tasks are submitted—one per device.The transfer now progresses. You may close the Software Upgrade window, or continue with other tasks. Closing the window does not effect any of the transfer processes that may be running in the background.Or you can switch to the Progress tab to view the status of the transfers.

9. Click on the Log tab and look at the Progress column to ensure that all files have correctly updated. The module is automatically rebooted following an upgrade procedure.

Discovering Devices Using the Drag-and-Drop MethodIf you are unable to discover the device (as described in step 2 on page 24), follow these steps to upgrade the firmware using the drag-and-drop method:1. Download the appropriate most recent upgrade package from the

our Web site or from your CD-ROM, and then unzip the upgrade package.

NoteClosing the Software Upgrade window does not effect any of the transfer processes that may be running in the background.

NoteIf you try to log off or exit the CCS software while a transfer is underway, a notification window will alert you that processes are still active and will ask if you want to terminate these processes.



2. If the affected module has not been discovered by your CCS software application, enter the Build mode, and then drag or copy and paste the module’s device icon from the catalog folder into the Network or Discovery folder.

3. Right-click the device icon and then select Properties. 4. On the NRO or Device tab of the Navigation Properties box, enter

the IP address of the frame that holds the module. (See Figure 2-14.)

Figure 2-14. Navigation Properties Box

5. In the third field, enter the slot number of the module as shown in Figure 2-15, and then close the window.

To enter information into the frame and slot field (the third field in CCS-3.0), follow the convention shown in Figure 2-15 on page 28. The first number in the third field should always be 1. The second number should always be 0. The third number is the slot number in the NEO frame (for example, 10). Resource modules will now appear as 17 or 18 in this third number spot, instead of 101 and 102, as in earlier versions. In the unlikely event that you cannot discover the frame, the number 0 may be used to represent the frame.

NoteThe Device ID line will be slightly different than in previous versions. The acronym EP will appear—instead of IP—in the first Device ID field. The frame and slot number now are entered in the third field instead of the last field. And the area in which you should not enter any data is now the last field (previously the third field).

Do not make changes in this field

Enter frame IP number here



Figure 2-15. Inserting Numbers in the Frame and Slot Field

6. Continue upgrading your device’s firmware, starting with Step 3 on page 25.

Correcting a Failed Upgrading ProcedureFirmware upgrades may fail in the event of network interruptions, power failures, or if too much data is uploaded to the NEO module. Often, uploads of too much data can occur for one of the following reasons:• The boot file (typically vxWorks.lzs) was accidentally uploaded

during the fl0 procedure, instead of the boot procedure.• Files were sent to the wrong NEO module.• The particular hardware version of the module requires only some

(but not all) of the available fl0 files.• The upgrade .zip file was mistakenly sent to the module.All of these problems can be corrected by re-installing the firmware while in a fail-safe mode, as described in the following pages. When you are performing this procedure, check the appropriate readme file to confirm which files are needed. Use care to ensure that you upload the correct files to the intended module.Three general steps are involved in correcting a failed upgrading procedure. These steps are found in the following sections: 1. “Setting the Module to Fail-Safe Loader Mode” (see below)2. “Upgrading the Firmware in the Boot Folder in Fail-Safe Mode” on

page 29

Always set to 1Always set to 0 for NEO products

Insert slot number: -1 to 12 for regular modules-17 or 18 for resource modu-0 for a NEO frame



3. “Upgrading the Firmware in the Fl0 Folder and Rebooting the Module” on page 31

Setting the Module to Fail-Safe Loader ModeFollow these steps to set a NEO module to the fail-safe loader mode:1. Remove the affected module from the NEO frame.2. Press the Nav switch down while simultaneously pressing both the

Escape and Enter buttons.

Figure 2-16. Buttons on a Typical Card Edge

3. While still pressing the buttons and the navigation switch, reinsert the module into the frame and hold for approximately three seconds until the display on the module reads Offline-H (or Offline-L) Upload Required.

Upgrading the Firmware in the Boot Folder in Fail-Safe ModeEnsure that you follow these steps in the exact sequence when upgrading the firmware in fail-safe mode: 1. Download the most recent appropriate upgrade package from the

our Web site or from your CD-ROM, and then unzip the upgrade package.

2. If the affected module has not been discovered by your CCS software application, enter Build mode, and then drag or copy and paste the module’s device icon from the catalog folder into the Network or Discovery folder.

3. Right-click the device icon and then select Properties. On the Device tab of the Navigation Properties box, enter the IP address of the frame that holds the module. (See Figure 2-17.)

Figure 2-17. Navigation Properties Box

5. In the third field, enter: 1.0.[slotnumber](Where, for example, 1.0.5 would refer to the module in slot 5 of the frame.)

6. Close the window.7. Double-click the device icon.

The Configuration... box opens. On the File Transfer tab, the /slotx/boot (where x is the slot number) directory appears in the Select the device directory to transfer to: field.

8. Click Add, and in the Add Upgrade Files box, browse, select the boot folder in the module’s upgrade package and then click OK.

9. Choose the vxWorks.lzs file and then click OK.10. Click Perform Transfer and then click Yes.

This may take several minutes.11. Wait for the message File transfer to device succeeded in the

status bar.See “Upgrading the Firmware in the Fl0 Folder and Rebooting the Module” below to continue the correction procedure.

NoteThe Device ID line will be slightly different than in previous versions. The acronym EP will appear—instead of IP—in the first Device ID field. The frame and slot number now are entered in the third field instead of the last field. And the area in which you should not enter any data is now the last field (previously the third field).

Do not make changes in this field

Enter frame IP address here



Upgrading the Firmware in the Fl0 Folder and Rebooting the ModuleThis procedure is meant to be performed directly after “Upgrading the Firmware in the Boot Folder in Fail-Safe Mode” on page 29.Follow these steps to reboot the affected NEO module:1. Click Reboot Device, and then click Yes.

After the module has rebooted, a message box advises you to wait until the device has rebooted.

2. Wait 30 seconds.3. On the File Transfer tab, select the /slotx/fl0 (where x is the slot

number) directory in the Select the device directory to transfer to: field.

4. Click Add, browse and select the fl0 folder in the module’s upgrade package, and then click OK. Check the readme for the upgrade package to ensure that you are adding the correct files.

5. Select the files shown in the Add Upgrade Files box, and then click OK.

6. Select and delete unwanted files (for example: vxWorks.lzs) in the Add upgrade files for transfer to device: field by clicking Remove.

7. Click Perform Transfer and then click Yes.8. Wait for the message File transfer to device succeeded.

This may take a moment.9. Click Reboot Device and then click Yes.10. Wait 30 seconds, and then close the Configuration... box.

The module name appears at the card edge.The upgrade procedure is complete.

NoteSome NEO modules will reboot automatically. In these cases, the Reboot button will be grayed out. During this time, the module’s card-edge display will show the word Rebooting before the name of the module appears. These modules do not require the fl0 file.

CautionYou must delete unwanted files in the Add upgrade files for transfer to device: field before transferring the files. Otherwise, the upgrading procedure will fail.

Operation

OverviewInstallation, navigation, configuration, and setup information is now included in the NEO FR-3901, FR-3903, and FR-3923 Mounting Frames Installation and Operation Manual. If your current NEO frame manual is Edition A, B, C, or D, you will need to download an updated version from our Web site (www.broadcast.harris.com/leitch) to access this information.This chapter describes how to operate the ACO-3901 module using card-edge controls. The following topics are found in this chapter:• “Operation Notes” on page 34• “GPO Pinouts” on page 34• “Cross-Functional Parameter Changes” on page 36• “Navigating the Operator and All Lists” on page 39• “Operator and All List Parameters” on page 40• “Setup Parameters” on page 56• “Alarms” on page 57• “State Recovery Parameter Availability” on page 62• “LED and Module Indicators” on page 63



Chapter 3: Operation

Operation NotesWhen using the ACO-3901 module, the following operation notes should be observed:• Although the effect of a parameter change may appear to be

immediate, the module requires 20 seconds to save the latest change. If another change is made during these 20 seconds, the first parameter change and the second parameter change will not be saved until 20 seconds after the second parameter change. There is no limit to the number of changes that can be made within 20 seconds of each other. However, none of these changes will be saved until 20 seconds after the last parameter change.

• When the FctryRcl (factory recall) parameter is set to Yes, the module takes several seconds to reset all of the parameters. (See the “Operator and All List Parameters” on page 40 or the “Tree View Parameters” on page 75 to view the factory recall default settings.) Setup parameters are not affected by the factory recall mode.

• Some parameters will be locked out if certain settings are made. When this occurs, a lock icon will appear beside the affected parameters in the card-edge VFD.

GPO PinoutsTable 1-3 on page 7 lists back module pins of the DB-15 connector that include the GPI output closures labelled GPO_CL1 and GPO_CL2. These two pins are controlled by a number of parameters that begin on page 50 in the Operator and All List, and page 80 of the Tree View.To configure the two GPOs, enable or disable those parameters (shown in the following excerpt from pages 50 to 51 of the Operator and All List). Although the names of the parameters begin with “GPI,” they are in fact, used to configure the GPOs.

CautionFailure to observe these “Operation Notes” will result in accidental changes to the module’s parameter settings.



The GPO_CL1 and GPO_CL2 connections are normally open with respect to each other and there is a relay connected between them. When any of the enabled GPI triggers are activated, the relay is closed, and this closes the connection between the GPO pins. The relay has a capacity of 0.5 amps.You can use any or all of these parameters to program the activation of alarms for the ACO-3901.

Setup ParametersYou can modify the Setup parameters to configure the card-edge controls for your personal needs. The Setup section appears at the end of all three navigation lists and consists of these items:• Alarms• Navigation modes• Adjustment modes• Browse modes• Scroll modes• Display intensity• Parameter descriptions• Name• FrameIP• Sync full• About mode

The structure of the Setup menu is located at the end of Appendix A: “Tree View Navigation.” See your NEO FR-3901, FR-3903, and FR-3923 Mounting Frames Installation and Operation Manual for more information on Setup items, including descriptions and operation notes.

NoteSetup parameters on a local or remote control panel may be different from the card-edge parameters described here.



AlarmsThe ACO-3901 has two types of alarms: traditional CCS-enabled alarms, and additional user-configurable hardware alarms.

CCS-Enabled AlarmsACO-3901 modules provide a default list of 70 CCS-enabled alarms. You can disable these alarms by modifying the Alarms parameter in the Setup section.When you select Alarms, the active alarms are visible in the display, below Config (Configurations). If no alarms are active, only Config appears.

Alarm SynchronizationAlarm synchronization is available for this module if your NEO frame contains a 3901RES-E resource module that supports the feature. When active, alarm synchronization ensures that the alarm configuration settings of card-edge controls and the CCS control software and control panels are consistent.If the ACO-3901 module is set for local control, the alarm settings will appear the same at both the card edge and via CCS, but the settings can only be changed using the card-edge controls. If the module is set for remote control, the alarm settings can be changed via both the card edge and CCS control software and control panels.Alarm configuration settings undergo DejaView (state recovery) automatically. This means that when a module is hot-swapped, the alarm configuration for the new module is updated to the settings of the module that was previously in that slot. See “State Recovery Parameter Availability” in this chapter for more information.

Identifying the Cause of an AlarmTo identify the reason for an alarm, select the active alarm, and then press Enter. A scrolling message appears on the VFD describing the cause of the fault.



Enabling or Disabling a CCS Alarm ParameterTo enable or disable an alarm parameter, follow these steps:1. Select Alarms, then select Config, and then press Enter.2. Select one of the alarm parameters, and then press Enter.3. Press Enabled or Disabled. 4. Press Enter to activate the selection.

Restoring Default SettingsTo restore the alarms to their default settings, follow these steps:1. Select Alarms, select Config, and then press Enter.2. Scroll down the list of alarms, and then select Reset.3. Press Enter to activate the selection.

The following table lists the default alarms for the ACO-3901 module. You can enable or disable these settings, but you cannot change the level of the alarm.

Type of Alarm





Hardware AlarmsThe ACO-3901 has additional hardware alarms that operate independently of the CCS-enabled alarms. Unlike CCS alarms, you can change the Major or Minor designation of the hardware alarms. These alarms are represented by the Major or Minor LEDs located on the left front corner of the ACO-3901 module.The following parameters enable or disable the hardware alarms:• AudPPSEn• AudSPSEn• AudMTG1En• AudMTG2En• AudExtEn• AudOutEn• AudCPUEn• AudM1VBEn• AudM2VBEn• AudExtVBEn

Power supply problems

PrimPSFail Primary Power Supply Fail

SecPSFail Secondary Power Supply Fail

Minor Loss of the secondary power supply (external 24 V source)

PSFail Power Supply Fail Major Loss of the primary power supply (NEO frame power supply) or the secondary power supply (external 24 V source)


Type of Alarm





The following parameters set the level of the hardware alarms:• AlrmPPSEn• AlrmSPSEn• AlrmMTG1En• AlrmMTG2En• AlrmExtEn• AlrmOutEn• AlrmCPUEn• AlrmM1VBEn• AlrmM2VBEn• AlrmExVBEnThese alarms are located on pages 49 to 50 in the Operator and All List Parameters table, and in the Processing>Monitoring section of the Tree View on pages 79 to 80.

State Recovery Parameter AvailabilityThe parameter settings for this module are automatically saved onto the 3901RES-E resource module installed in your NEO frame every five minutes. If a module should fail and be replaced with a cold spare, the state parameters can be automatically recovered. For more information on this feature, see the NEO FR-3901, FR-3903, and FR-3923 Mounting Frames Installation and Operation Manual (Edition E and above).



LED and Module Indicators

General InformationThe ACO-3901 Automatic Changeover Unit has ten card-edge LEDs and five module indicators.The module indicators include a Major Alarm and a Minor Alarm. These alarms alert users to failures or impending failures within the module. They are found in the following locations:• As red or yellow LEDs on the 3901AIC Alarm Interconnect

Module or the 3901RES-E Resource Module (visible via light pipes through the frame’s front panel)

• As part of a list of activated alarms found in the ACO-3901 Setup menu

• In external systems connected to the alarm contact closures at the back of the NEO frames

• On a PC screen where Pilot or another GUI-based control application is being used

The ACO-3901 also has a unique redundant alarm system, in which Major and Minor Alarms are reported in the LEDs. For more details, see page 65.

Appendix A

Tree-View Navigation

OverviewThe Tree View is one of the three navigation modes available on the ACO-3901 module. Unlike the other navigation modes, the Tree View is a multi-level list of parameters, arranged in the following main groups:• “Input” on page 75• “Other” on page 79• “Output” on page 79• “Power” on page 79• “Processing” on page 79• “Setup” on page 80(See page 56 for more information on the Setup parameters which govern the operation of the card-edge controls.)

This appendix consists of instructions for navigating the lists (see page 74) and the Tree View Parameter list.


Appendix A: Tree-View Navigation

Navigating the Tree ViewTo navigate and then view or change a parameter from the Tree View, follow these steps:1. Open the front panel of the NEO frame.2. Press any card-edge control to turn on the VFD display.

The message ACO-3901 will appear as the banner on the card-edge display.

3. Press the Enter button.The first two items in the Level One list will appear.

4. Click Nav- (down) on the Nav-/Nav+ switch to view more items in the Level One list.

5. Select the desired item in the Level One list, and then press Enter.This leads you to the Level Two list.

6. Repeat steps 3 and 4 to view more items in Levels Two, Three, and Four.

7. If the parameter is selectable, slide the bar to the desired parameter using the Nav+/Nav-switch.ORSelect the desired item in the Level Four list, and then press Enter.

Once the Level Four parameter is set or viewed, you can leave the parameter in its current state, or return to the banner. To return to the ACO-3901 banner, repeatedly press the Escape button. Close the front panel again after you have completed the procedure to prevent the frame from overheating.

NoteIf you do not wish to make changes to your settings, return to the previously selected item in the list, and then press Escape to move up a level. See SelPar Adj Mode in the Setup section at the end of the Tree View to enable or disable this delayed adjust mode feature.

NoteAfter several seconds of inactivity, a scrolling message will appear, describing the purpose of the currently selected parameter.



Tree View ParametersUnlike the Operator and All List navigation modes, the Tree View is a multi-level structure that includes all of the available card-edge parameters. Parameters with the designation [RO] are “read-only.” An asterisk (*) indicates the default user range or value.See page 74 for instructions on navigating the Tree View.
