Setting the Card ID Switch
The multiplexer module can be an HP E1351A, HP E1352A or HP E1353A depending on which terminal module is installed. With a normal connection, the terminal module will automatically configure the module for the appropriate model. To identify a module without a terminal module, set the Card ID switch as shown in Figure
Model | Value | Configuration |
HP E1351A | 0 | all pins open |
HP E1352A | 8 | pin 3 closed |
HP E1353A | 2 | pin 1 closed |
For normal connections, leave the switch at the factory setting which is all pins open.
