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 2-6. The ID numbers are:
