Configuring the Relay Multiplexer Modules 25Chapter 2
Using the
Switchbox
Configuration
Use this configuration when:
1. Simultaneously closing multiple channels on multiple modules.
2. Other multimeters/modules cannot control the multiplexer modules.
To use this configuration, set the first multiplexer module's logical address
to a multiple of 8. Set the next multiplexer module's logical address to the
next address value, the third module to the next address value, and so on.
The following shows the logical address settings of a switchbox with the
first multiplexer module address set to 112.
To program the switchbox, use the programming information in this manual.
Verifying Correct
Logical Address
Settings
To verify that the modules have the correct logical address setting, query the
E1300A/E1301A Mainframe or E1405B/E1406A Command Module as
follows:
E1301A Mainframe - From the “Select a Instrument” prompt of the front
panel, select the following menus:
SYSTEM
CONFIG?
LADDS
E1300A Mainframe, E1405B, or E1406A Command Module with an
RS-232 Terminal - From the “Select an Instrument” prompt, select the
following menus:
SYSTEM
CONFIG?
LADDS
If no front panel or RS-232 terminal is available, send the following SCPI
query command to the mainframe/command module:
VXI:CONF:DLAD?
The returning string contains all logical addresses in the system.
