I am working on setting up some new equipment, a second setup of one we already have. In both setups, we are using only one GPIB-ENET/100 and one GPIB-232CV-A with LabVIEW. On the original setup, which works fine, here is the order of connection:
Computer --> GPIB-ENET/100, connected by an ethernet cable
High-Voltage Power supply --> Lock-In Amplifier --> GPIB-ENET/100 --> GPIB-232CV-A, daisy chained together with GPIB cables
The GPIB-232CV-A has a dip switch address 1, and is also running a DB-9 cable out to a series of stepper motor controllers. In my Global addresses VI, these stepper motor drives are given a global address of 1, which I understand. What I don't understand is why the High Voltage has an address of 3 and the Lock-In has an address of 4, which my other VI's do call out in order to communicate with them. Does this have something to do with the daisy chain order? Again, there is only one GPIB-232CV-A being used, and it has an address of 1. Thanks.
