Modules Identification
You may have more than one module or chassis connected to the same host PC.
The following figure illustrates an example of the connection.
Figure 2-9 Identifying modules location
To identify the location of the modules, a pre-configuration setting is needed
before the synchronization or triggering event begins. Follow the steps below:
1 Send the following command to the modular chassis to trigger it. This
command will be used to transmit the number to all USB modules via Trigger
Bus (TRIG [0..7]). You can choose from 0 to 255 for your chassis number.
SYSTem:IDentity {0|1|2|3…|255}
2 Send the following command to every module in the chassis to query each of
the slot and chassis numbers.
SYST:CDES?
NOTE
Select 0 to disable the output. The modular chassis will not be triggered to send
any output to the USB modules.
