I. The 208 DAIU

A) Function Description

The 208 Data Acquisition Interface Unit (DAIU) is a multi-channel

processing unit that interfaces directly to a computer. Two DAIUs can be

connected together for up to 16 channels of simultaneous data acquisition.The computer controls data acquisition. As data is captured by the 208

DAIU, it is downloaded directly into the computers RAM (random access

memory).

REV C 134515

Input Signals: Each 208 DAIU box accepts up to 8 channels of

displacement, velocity, and acceleration inputs. The 208 DAIU also

accepts process variable inputs, and input signals from most generic

dynamic transducers.

Keyphasor Inputs/Outputs: Up to 2 keyphasor! inputs can be assigned to

pairs of the signal input channels, allowing data acquisition on

machine trains with more than one shaft speed. See the discussion on

Keyphasor Assignments in Section 3 of this course for rules on

connecting Keyphasor signal cables to the 208 DAIUs.

Relay Inputs: Data acquisition can be initiated via remote relay by using the

Relay Input. (See Chapter 11 Advanced Sampling, page 15)

Communication Ports: The 208 DAIU is connected to the computer and to

an additional 208 DAIU through the Computer/DAIU Input and

DAIU Output ports.

Power Supply Input: Input from DC adapter is used to charge the internal

battery and to run on AC power.

C) The 208 DAIU Internal Battery

The internal nickel-cadmium battery will last up to 4 hours on a singlecharge, and can typically handle up to 500 full charge cycles with less than

15% capacity loss. A full drain of the battery is recommended every 1-2

months to optimize battery performance. Charge times vary depending on

the battery type:

Battery Part Number Full Recharge Time

Standard Part No. 107305-01 Up to 5 hours

High Temperature Part No. 107306-01 Up to 15 hours

Power Supply Charger Upgrade: A hardware upgrade is available which

improves the performance of the internal battery charger. The

upgrade is accomplished by replacing PWA 102387-01 with PWA

131866-01.

II. Computers

To operate ADRE!for Windows version 4.70, the target computer must have at

least the following requirements:

486/Pentium!processor

Windows98, NT 4.0, or 2000

16 megabytes (MB) RAM

80 MB hard disk space

Up to 28.2 MB additional hard disk space for each database stored (if no

external medium)

CD-ROM drive for installation

VGA display

Mouse

Enhanced Parallel Port (EPP), available ISA slot, or available PCMCIA

slot

Several connecting options exist for operating ADRE! for Windows on your

computer. These options depend on whether you are installing ADRE on a laptop

or a desktop computer as well as the operating system that you are using.

REV C 134515

A) Laptop Computers

Connecting options for laptop computers depends upon the operating

system used.

Figure 3. Laptop Computer Connected to ADRE 208-P DAIU

Windows NT 4.0/2000

To use ADRE!for Windows with a laptop computer and Windows

NT 4.0/2000, you must have:

1. A 208-P DAIU

2. A 25-80 pin EPP to DAIU connector cable

3. An Enhanced Parallel Port (EPP) that can be set to EPP mode by

the user or an EPP PCMCIA card

98, you must have:

1. A 208-P DAIU

2. A 25-80 pin EPP to DAIU connector cable3. An Enhanced Parallel Port (EPP) with EPP BIOS support, an

Enhanced Parallel Port (EPP) that can be set to EPP mode by the

user, or an EPP PCMCIA card


6/28


REV C 134515

Laptop computers must use the 208-P DAIU instead of the 208 DAIU. This

is because the 208 DAIU can only connect to computers using an ISA

port/card which laptop computers do not have.

If your laptop printer port is an Enhanced Parallel Port (EPP), you canconnect the 208-P DAIU directly to it using the 25-80 pin connector cable.

If your laptop printer port is not an EPP, you will need to create one by

obtaining an EPP PCMCIA card, such as the Quatech SPP-100 PCMCIA

card, and connect the 208-P DAIU to it using the 25-80 pin connector cable.

Figure 4. 25-80 pin Connector Cable

B) Desktop Computers

Connecting options for desktop computers depends upon the operatingsystem used.

Windows 2000

To use ADRE!for Windows with a desktop computer running

Windows 2000 you must have:

1. A 208-P DAIU


3. An Enhanced Parallel Port (EPP) that can be set to EPP mode by

the user


7/28


REV C 134515

Windows NT 4.0


Windows NT 4.0 you must have:

1. A 208-P DAIU2. A 25-80 pin EPP to DAIU connector cable

3. An Enhanced Parallel Port (EPP) that can be set to EPP mode

by the user or an ISA EPP card, such as the Quatech MMP-100,

with an unused ISA slot and address.

If your desktop printer port is an EPP, you can connect the 208-P

DAIU directly to it using the 25-80 pin connector cable. If your

desktop printer port is not an EPP, you will need to create one by

obtaining an EPP ISA card and connect the 208-P DAIU to it using

the 25-80 pin connector cable.

REV C 134515

In addition to the 208-P DAIU, desktops running Windows 98 can

also use the 208 DAIU. This is the only platform that supports the

208 DAIU.

To use ADRE!for Windows with a 208 DAIU, you must have:

1. A 208 DAIU

2. A 68-80 pin ISA to DAIU connector cable

3. An unused ISA slot

4. An empty ISA address space

5. A special half length ISA interface card provided by Bently

Nevada.

Figure 6. Desktop Computer, ISA Communications Card, and 68-80 Pin ISA to

DAIU Connector Cable

Note: While collecting data through your EPP-compatible port, you cannot

simultaneously use the port for other devices. You cannot have a printer, tape

drive, or other device connected to the LPT port. Even having devices assigned to

this port may cause problems with data collection. These devices will interrupt

signals to and from the DAIU(s) unpredictably.

Note: You cannot connect one 208-P DAIU and one 208 DAIU together. If you

are using two DAIUs, both must be the same type.

Figure 8.The Data Path

All data, both during and after sampling, remains in computer memory

(RAM) until saved to the hard drive or other storage medium. Be sure to

SAVE YOUR DATA! If you have Repeating Data Collection selected in

the user preference (See Setting ADRE!for Windows Preferences later

in this section), then you will have a copy of your data on the hard disk. It

is still recommended for you to save your data with your own naming

convention. The Database created from the Repeating Data Collection

can then be a reliable backup copy of your raw data.

REV C 134515

B) Running ADRE!!!!in a Windows Environment

1) Setting the Computer Clock

During sampling, ADRE!for Windows uses the computers internal

clock to record the date and time of each sample record. Though thedate and time tags for a database can be adjusted after sampling

through the ADRE! for Windows utility menu, insuring that the

computer clock and calendar are set correctly prior to sampling is

good practice.

2) Selecting a Printer Driver

ADRE! for Windows automatically uses the default Windows

printer driver each time the program is executed. To select a default

Windows printer driver from Windows 98, double-click on the "My

Computer" icon on the Desktop. Next, select Control Panel, thenPrinters. Select an installed printer by clicking on File, then Set as

Default.

Figure 11. Setting the Default Windows Printer


13/28


REV C 134515

You can select any installed Windows printer from within ADRE! for

Windows. This selection, however, does not change the default Windows

printer. The next time ADRE!for Windows is run or a different database

is opened (either new or existing), the default Windows printer will be

selected again.

To select a printer from within ADRE! for Windows, click on the File

pull down menu, select Print, then click on the Printer Setup button for

options.

Figure 13. Setting Preferences

Database Auto Save

Since data is stored generally in computer memory after sampling

until manually saved to a storage medium by the user, enabling

autosave options can provide temporary protection against the

accidental loss of data. When a Database Auto Save option is

selected, or checked, the current database is saved to the

C:\ADREWIN\DATABASE\DEFAULT

subdirectory during execution of the specified function:

On Exit

Upon exit of ADRE! for Windows software, the current

database is automatically saved to the default subdirectory. No

prompt is given.


15/28


REV C 134515

Retrieve Database

When a database is retrieved and loaded into ADRE! for

Windows, the database is automatically saved to the default

subdirectory.

Leave Store EnableUpon the close of the Store Enable function, the newly

collected database is saved to the default subdirectory.

Realtime Backup

When Realtime Backup is selected, or checked, the current database

is saved to the backup subdirectory C:\ADREWIN\BACKUP during

execution of data collection. If both Minutes and Samples numbers

are non-zero, ADRE! for Windows will backup the data whenever

the time interval expires or the sample count reaches the limit.

Minutes

The time interval in minutes between two consecutive backups.

NOTE: ADRE downloads samples from the DAIU in groups of 10 vectors. The

backup database will include only samples that have been downloaded from the

DAIU to the computer. For example, if only 7 vector samples have been taken

by the DAIU when the backup database is saved, there will be no samples in the

backup database (because those samples have not yet been downloaded to the

computer). If 15 vector samples have been taken when the backup database issaved, there will be 10 samples in the backup database.

Samples

The number of samples collected between two consecutive

backups.

Data Acquisition

Repeat Data Collection

When Repeating Data Collection is selected, ADRE repeatsdata collection and saves each database until the amount of free

disk space on the disk drive is less than 28.2 MB. Data

collection will stop and the last data collection will need to be

saved by using the option: FILE - SAVE.


16/28


REV C 134515

Each database collected while in repeat mode will be saved as:

\ADREWIN\DATABASE\REPEAT\DDMMMYY\HOUR_MIN_SEC

The DDMMMYY and HOUR_MIN_SEC directories will bethe date and time of the first sample in the database with a valid

time tag. If the first sample in the database was collected with

a time tag of 01 May 2000 12:01:01, the database would be

saved as:

\ADREWIN\DATABASE\REPEAT\01MAY00\12_01_01.

If there are no samples in the database with a valid time tag, the

database will always be saved as:

\ADREWIN\DATABASE\REPEAT\01JAN80\00_00_00.

Comments will be generated containing the following

information for each database:

Session started with Database: dd mmm yy - hr:mn:sc

(Date and time of the first database)

Repeating Data Collection must be selected in order to activatethe Useable Drive and Search options. The Path will also be

dimmed unless Repeating Data Collection is checked.

When this option is selected, a System Error message may be

displayed if Windows cant find a disk in a Useable Drive.

Selecting the Cancel button will remove the message from your

screen and allow you to continue.

Reset Trigger

When you select Repeating Data Collection and ResetTrigger, ADRE will collect data until the database is full, save

it, and then automatically prepare to collect data. If the

machine is operating in the triggered region, data collection

will trigger and ADRE will again collect data and save the

database when it is full. This will occur repeatedly until the

amount of free disk space on the disk drive is less than 28.2

MB. If the machine is not operating in the triggered region, no


17/28


REV C 134515

more data will be collected after the first database fills up and

is saved. However, the system will again collect data if the

machine conditions change to meet the trigger requirements. If

free disk space runs low (below 28.2 MB), data collection will

stop and the last database will need to be saved by using theoption: FILE - SAVE.

If you select Repeating Data Collection, but do not select

Reset Trigger, after the first database is saved, the system

will automatically begin collecting data again. The system will

collect and save data repeatedly (no matter what the machine

conditions are) until you manually stop data collection or the

hard drive contains less than 28.2 MB of free space.

If you select Reset Trigger and have also configured your

system to Trigger on Time, you will get a warning message that

data collection will not re-trigger. This is because the time

trigger condition can only be true once.

Useable Drive

The useable drive is the drive to which you will save each of

your databases when Repeating Data Collection has been

checked. In order for a drive to be useable, it must have morethan 28.2 MB of free disk space and it must be a writeable disk

drive. Drives A and B are excluded from the list of useable

drives since they cannot normally be used to store 28.2 or more

megabytes of information. Click on the Down Arrow button to

see a list of available drives.


18/28


REV C 134515

Figure 14. Useable Drives

Search

Click on the search key to find all the Useable Drives (from D -

Z) on your system. Note that only fixed and removable drives

can be used for data storage. If a useable drive becomes

invalid or does not show up on the list when it normally should,

check the drive to make sure it has sufficient free space and

that it is not write protected.

Path

The path or location where the databases will be stored on the

useable drive. Each database will be stored in the

\ADREWIN\DATABASE\REPEAT\DDMMMYY\

subdirectory with the filename HOUR_MIN_SEC, where

DDMMMYY is the date when the database was collected and

HOUR_MIN_SEC is the time of the first vector sample with a

valid time tag. For example if the first sample in the database

was collected with a time tag of 01 May 2000 12:01:01, the

database would be saved as:

\ADREWIN\DATABASE\REPEAT\01MAY00\12_01_01.

RPM Values

ADRE does not always sample at the exact delta RPM value.

Because it may be a couple of RPMs off, it normally rounds the actual


19/28


REV C 134515

RPM value to the nearest delta RPM value (up to a maximum value

of 10) to simplify plot presentation and add clarity. By default, the

Disable RPM Rounding checkbox is left unselected to display the

rounded RPM values in each plot displayed. If you want to display

the exact RPM value that each sample was collected at, select theDisable RPM Rounding checkbox. The two figures below display

the same samples (collected with delta RPM setting of 8) and the

difference that this preference setting makes.

Figure 15.Samples displayed with RPM Rounding Enabled

Figure 16. Samples displayed with Disable RPM Rounding selected


20/28


REV C 134515

Note: If you have a plot open and you change the RPM Values

setting, you must close and reopen the plot to see the change.

208 DAIU Settling

The starting store enable and the sampling mode feature in storeenable requires the 208 DAIU to go through a settling time. If a

bandwidth of 120 is selected, a long settling time is not required and

no option will be given to select a 208 DAIU settling time. However,

if a bandwidth of 12 is selected, it is recommended to check the 12

RPM (7 seconds) box, allowing for a 7 second delay before the data is

downloaded. If this is not done, the data collected immediately after

a sample mode change will show the 1X, 2X, and nX charging up or

settling.

Note: Older versions of ADRE! for Windows (before 4.60) have a FileManager option within the Preferences dialog box. (The File Manager

feature will be discussed further in the next subsection) The default File

Manager for older versions is winfile.exe. To change the File Manager

preference, type in the desired File Manager path and name (i.e.,

c:\windows\explorer.exe). ADRE version 4.60 uses Windows Explorer

when the File Manager feature is selected and does not offer a choice in the

Preferences dialog box.

D) File Manager

ADRE allows you to access Windows Explorer without leaving the programto move, rename, and delete files. To run the File Manager from within

ADRE, click File from the main menu bar, then select File Manager.

E) Saving ADRE!!!!for Windows Databases

ADRE! for Windows databases are stored in directories rather than

individual files. When saving a database, the directory name is selected ortyped in. The default path is C:\ADREWIN\DATABASE\directory

name. The File pull down menu option has two ways to save a database:

Save and Data Range Save:

Save

- Current directory name listed in entry field

- Vector and gap reference data- Comments entry field (comment.txt)

- Empty database (configuration only)


23/28


REV C 134515

Data Range Save

- Directory name entry field blanked out

- Data range limit adjustment

- Required disk space

- Comments entry field (comment.txt)

Database Comments

To save notes about your sample run, type the notes into theComments box. These notes will be saved as part of your database in

the comment.txt file, which is located in the database subdirectory

Notes.

Saving to Multiple Floppy Disks

Databases requiring more disk space than available on a single floppy

disk can be saved to multiple floppy disks. When the first disk is full,

the program will prompt for an additional disk:

Figure 20. Saving To Multiple Floppy Disks

Figure 19. Using Data Range Save


24/28


REV C 134515

The Default Subdirectory

Figure 21. The Default Subdirectory

Each time ADRE! for Windows is run it automatically loads the

database currently residing in the

C:\ADREWIN\DATABASE\DEFAULT\

directory. The Database Autosave options, when selected, use this

directory to store databases. Each time a database is stored to the

C:\ADREWIN\DATABASE\DEFAULT\directory, the previous one is overwritten.

Note: This directory should never be deleted as this will cause

ADRE!for Windows not to start up and you would get the following

message:

Figure 22. Loading ADRE!for Windows Error Message


25/28


REV C 134515

F) Caution Screens

The following operations are the most common cause of caution screens:

Configuration ChangesChanges to the configuration of an existing database that affect how

the DAIU collects data will invalidate the database. These changes

result in a configuration error because the revised configuration no

longer matches the existing data. A caution screen gives you the

opportunity to protect the original database.

Figure 23. Warning Screen Following Configuration Change

Opening a Database or Entering Store Enable

Either of these actions, when done prior to saving newly acquired

data, require erasing the current database from computer memory andbringing in new data. A caution screen gives you the opportunity to

protect the original database.

Figure 24. Caution Screen When Going to Store Enable or Opening a Database


26/28


REV C 134515

Entering Store Enable in some situations would delete the vector waveform

data in memory and in the Backup Directory. A caution screen gives you the

opportunity to protect the original database.

Figure 25. Caution Screen Going to "Store Enable"

Overwriting a Previously Stored Database

Figure 26. Caution Screen When Overwriting a Database

After a database has been stored to disk, it is often desirable to make

changes such as adding plot configurations, adjusting the limits of the

database range, and changing the run type. To save these changes,

you can either overwrite the original database (save to same name) or

save to a database under a new name. If you choose to save to the

same name, the caution screen above reminds you that you are about

to overwrite the original database.
