The multiplexer modules are programmed either in a switchbox or scanning
voltmeter configuration. To program the multiplexer modules using the
Standard Commands for Programmable Instruments (SCPI), you must select
the controller language, interface address, and SCPI commands to be used.
See the HP 75000 Series B Installation and Getting Started Guide or the
HP E1406 Command Module Manual for interface addressing and
controller language information of multiplexer modules in a switchbox or
scanning voltmeter configuration. If using the HP E1300 Mainframe or
HP E1405 Command Module, you MUST have version 06.00 (or
greater) firmware for the Multiplexer Modules to properly identify.
Note
This discussion applies to SCPI programming. See Appendix B
("16-Channel Relay Multiplexer Registers") for details on multiplexer
modules registers.
To address specific channels within a multiplexer module in a switchbox or
scanning voltmeter configuration, you must:
•
send the appropriate SCPI command string to the switchbox or
scanning voltmeter (e.g.,
•
specify the card number
•
specify the channel number
The card number identifies the module within a switchbox or scanning
voltmeter configuration. The switch module with the lowest logical address
is always card number 01. The card number with the next successive logical
address is 02, and so on.
