Using and Troubleshooting the GPIB-VXI/C

LaSaddr

Purpose: Attach or detach a GPIB address to a logical address.

Command Syntax: LaSaddr <logical address>, <GPIB address>

Action: If <GPIB address> is not equal to 255, attach <GPIB address> to <logical address>.

If <GPIB address> is equal to 255, release <GPIB address> currently attached to <logical address>.

Attaching a GPIB address to a logical address that already has a GPIB address will cause the first GPIB address to be replaced by the new GPIB address. Attempting to release or change a GPIB address will result in a Delete I/O Link error if any of the following conditions is true:

The GPIB address does not exist.
The GPIB address is addressed to talk or listen; unable to delete.
There is still data in the GPIB address input or output queue.

For example, suppose you want to assign a GPIB secondary address of 2 to the instrument with LA 19. From IBIC, you would issue the following set of commands:

Note that a GPIB read (when the console mode is enabled) will return the response of the GPIB-VXI/C after changing the GPIB secondary address.
