Trying to use GPIB-130 and FINDLSTN or ibln. Hardware: GPIB>>Support Products>>GPIB-130
Problem: FINDLSTN and ibln are not useful commands when being used with the GPIB-130. The GPIB-130 Bus Extender listens to every primary address regardless of whether or not the GPIB-130s are in buffered or unbufferd mode. If the GPIB-130 Bus Extender is being used, FINDLSTN will find a listener at every primary address, and IBLN will always return a true. Solution: If necessary, a possible workaround is the following: 1. Put both GPIB-130s in unbuffered mode (dip switch on GPIB-130 box). 2. In place of IBLN do the following A. Change the timeout to a short period but not less that 1millisecond [ ibtmo(board,6)] B. Attempt to write to the address in question [ send(board,addr,"*idn?",NULLend) ] C. If the write times out (EABO, iberr=6), then there is no instrument at address 'addr' Related Links: Attachments:
