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?
3 You may need to perform some sorting routine to
determine which slot it is at and what is the assigned
number of its host chassis. If a chassis has six modules in
N O T E
Select 0 to disable the output. The modular chassis will not be triggered to
send any output to the USB modules.
