TreeView display. Use the Spy function to monitor DIO settings.
The Digital Input/Output Tests check the 20 Digital I/O lines on the Digital I/O
connector for output and input functions
RS-232 Digital Input/Output Test
To output bits use the DIO <mask>,<value> command. Set the mask to 1048575.
Use the command "DIO?" for input. The value can range from 1 to 1048575
(2^20 - 1).
1.
Set Signal Lines High
Set all of the signal lines high using the DIO
1048575,1048575 command.
2.
Verify Signal
Verify that all of the signal lines are equal to or greater than
+3.5 V dc.
3.
Set Signal Line Low
Set all of the signal lines low using the DIO 1048575,0
command.
4.
Verify Signal
Verify that all of the signal lines are less than or equal to
1 V dc. Leave them all low.
5.
Toggle Each Line
Toggle each line and verify that the signal line responds.
For example, to toggle DIO0 output, send the command DIO 1048575,1.
Physically verify that the signal line is off (high) and then use the DIO?
command to read back the setting. Clear the bit using DIO 1048575,0.
Physically verify that the signal line is on (low) and then use the DIO?
command to read back the setting. To toggle DIO 7, send the command DIO
1048575,128 followed by DIO 1048575,0. To toggle DIO 19, send the
