Figure3-6 Identifying modules location
In order to identify the location of the modules, a
pre-configuration setting is needed before the synchronization
or triggering event begins. Follow the steps below:
1Send 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 [0...7]. You can choose
from 1 to 255 for your chassis number.
SYSTem:IDentity {1|2|3…|255}
2Send the following command to every module in the chassis
to query each of the slot and chassis numbers.
SYST:CDES?
3You 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 it, then there will be a
total of 7 SCPI commands to send to chassis and modules.
