Notice:

All inputs labeled “A” are GROUND inputs, and all inputs labeled “B” are Contact Closure Inputs.

Never apply a Voltage to any contact closure input with consulting a NCD Engineer.

Introduction

CD Devices with Contact Closure Input monitoring capabilities will use this command set to read no less than 8 contact closure inputs with a single

query. This includes the ZSCAN series controllers and any NCD Devices equipped with a UXP Expansion Port and a USCS16, USCS32, or USCS48 contact closure input expansion board.

This SCAN Series command set allows the user to read anywhere from 1 to 32 banks of 8 inputs in a single query. A single bank contains 8 inputs. Reading 32 banks will report the status of 256 inputs.

This command has been enhanced to report more than one bank. Original ProXR Standard controllers are only capable of reading one bank of 8 inputs per query. The enhanced version allows you to include an optional parameter to read the selected bank plus 1 to 31 additional banks for a total of 32 banks per query.

Getting Started

Please refer to the hardware diagram for connecting your contact closure input device.

Base Station Software

Introduction

NCD Devices with Contact Closure Input monitoring will use this command set to read no less than 8 contact closure inputs with a single query. This includes the ZSCAN series controllers and any NCD Devices equipped with a UXP Expansion Port and a USCS16, USCS32, USCS48 contact closure input expansion board.

A single bank contains 8 inputs. All SCAN Series Devices are capable of Reading Banks 0 through 255 for a total of 256 firmware supported input banks (2048 total supported inputs).

This command has been enhanced to report more than one bank. Original Pro XR Standard controllers are only capable of reading one bank of 8 inputs per query. The enhanced version allows you to include an optional parameter to read the selected bank plus 1 to 31 additional banks for a total of 32 banks per query.

Base station Software

Run the NCD Base Station software to communicate with your SCAN Series controller. After connecting the controller to your computer, select the correct port or IP Address for your controller. You will see the dialog box shown in the screen shot below. Select ‘UXP SCAN Series Contact Closure Input Command Set’

as selected below.

9

Base Station Software

This software will give you a binary representation of the status of the selected bank.

Use the scroll bar at the top left to select the desired starting Bank.

Click the ‘Read Individual Banks’ button at the bottom left to read the status of the selected Bank.

Standard Version Command Set

Command Set—Standard Version

Read Single Bank

This command reads a single bank of inputs and reports a value from 0 to 255 indicating the status of 8 inputs in the selected bank. An optional parameter may be included to read from 1 to 31 additional banks for a maximum of 32 banks per query.

Send Bytes: Byte 1: Byte 2: Byte 3:

Function: Command Bank

Decimal Values: 254 175 0-255

Hex Values 0xFE 0xAF 0x00-0xFF

Receive Byte: Decimal: 0-255 (Up to 32 Bytes will be sent)

Hex: 0x00-0xFF

COMM Operator Examples:

254 175 0 Device Reads the First 8 Contact Closure Inputs and Returns a Value of 0-255

The controller will report the status of 8 inputs as a single byte of data. The following software method should be used to determine which inputs are actually high and low (Value = Byte Received from Controller; the "AND" function is a software function supported by most programming languages):

If Value AND 1 = 1 then Bit 0 is ON








Or you can do combinations to test multiple bits:

If Value AND 3 = 3 then Bits 0 and 1 are ON


If Value AND 7 = 7 then Bits 0, 1, and 2 are ON

If Value AND 255 = 255 then All Bits are ON

11

Command Set—Enhanced Version

Read Single Bank

This command reads a single bank of inputs and reports a value from 0 to 255 indicating the status of 8 inputs in the selected bank. An optional parameter may be included to read from 1 to 31 additional banks for a maximum of 32 banks per query.

Send Bytes: Byte 1: Byte 2: Byte 3: Byte 4: Function: Command Bank More

Decimal Values: 254 175 0-255 1-31

Hex Values 0xFE 0xAF 0x00-0xFF 0x

Receive Byte: Decimal: 0-255 (Up to 32 Bytes will be sent)

Hex: 0x00-0xFF

COMM Operator Examples:

Read 1 Byte:

254 175 0 Device Reads the First 8 Contact Closure Inputs and Returns a Value of 0-255

Read 3 Bytes:

254 175 0 2 Device Read the First Bank Plus 2 More Banks and Returns 3 Bytes

Read 5 Bytes:

254 175 5 4 Device Reads Bank 5 Plus 4 More Banks (6, 7, 8, and 9) and Returns 5 Bytes

The controller will report the status of 8 inputs as a single byte of data. The following software method should be used to determine which inputs are actually high and low (Value = Byte Received from Controller; the "AND" function is a software function supported by most programming languages):









Or you can do combinations to test multiple bits:



If Value AND 7 = 7 then Bits 0, 1, and 2 are ON

If Value AND 255 = 255 then All Bits are ON

NCD Base Station Software

Use the ‘UXP SCAN Quality Control and Diagnostics’ to help identify problems with the controller.

Select the appropriate number of inputs and begin testing by moving the program/run jumper to both positions. Once this test has passed, communication speed will increase (which makes testing a little faster). Next, connect a jumper wire to each input individually until you see PASS for each input. If a failure is detected, the corresponding input failures will be identified. If a failure is discovered, the device must be returned to NCD for repair services.
