Example 5, Trouble Shooting Program for SDMX50 Multiplexer, Datalogger

Control Ports, and Analog Measurements

The following program can be used to test the operation of the SDMX50

Multiplexer and the datalogger control ports.

;{CR10X}

;Program Name: Example 5

*Table 1 Program

01: 5 Execution Interval (seconds)

;The Following Instruction 20 configures all 8 Control Ports as Outputs.

;This allows the user to manually set the ports high (+5V) or low (0V) in order

;to check the port operation with a volt meter. Ports and flags can be set with

;the Keyboard Display (*6 Mode, Datalogger Manual Section 1.3) or from the Connect

;Screen of PC208W or LoggerNet.

1: Set Port(s) (P20)

1: 7777 C8..C5 = output/output/output/output

2: 7777 C4..C1 = output/output/output/output

;To test wiring and multiplexer operation, the user can set Flag 1 and

;Instruction 109 will switch the SDMX50 multiplexer(s) to channel 8.

;(Starting at channel 1 each time P109 is executed.)

;If Flag 1 is LOW Instruction 109 will NOT be executed. The default

;status for User Flags 1-8 is low.

;NOTE: While Flag 1 is high Intruction 109 will take control of the

;SDM ports 1-3. It may not be possible to follow the ports

;going High and low with a voltmeter while this is happening.

2: If Flag/Port (P91)

1: 11 Do if Flag 1 is High

2: 30 Then Do

3: SDMX50 Channel Select (P109)

1: 01 SDM Address ; Enter correct address for connected multiplexer

2: 8 SDM Channel

4: End (P95) ;End, If Flag 1

*Table 2 Program

02: 0.0000 Execution Interval (seconds)
