Using the Multiplexers in a VXIbus System
This section prepares the strain gage multiplexers for use in a VXIbus
system.
Identifying the
Terminal Module
The card ID jumpers and card ID switch (Figure 1-1) indicates which
terminal assembly is used. Since the HP E1345-66201 and HP
E1351-66201 assemblies are used with a variety of terminal modules, the
ID jumpers or ID switch may need to be changed. To reduce setup time and
avoid configuration errors, check the jumper or switch setting to make sure
they match the terminal module used.
Relay Multiplexers When the relay strain gage multiplexers are shipped from the factory, the card
ID jumpers are set according to the terminal module (E1355A/E1356A)
shipped with them (Figure 1-1). The system is able to identify the multiplexer
with or without the terminal module attached.
Note If the jumper setting does not match the terminal module attached, the
system will identify the card based on the jumper setting.
