May anyone please help me with this problem:-
I've got a GPIB card initialised to be the system controller and a
Rohde & Schwarz ESN Test Receiver that is a device in the ssytem.
I find that after passing control to this receiver using the following
commands, I fail to get it back to the GPIB card, as a result I end up
having to manually reset the receiver by turning power OFF/ON.
The commands that transfer control from the card to the receiver are:-
These commands are sent using a Send(int addr,char * cmd) library function.
Here I only give tou the command sent, but my program addresses the intended
"*PCB 21" //tells the receiver where to return co
"*PCB 23" //23 is the receiver's address
"LISTEN 21" //21 is the address of the GPIB card
"TALK 23 TCT" //receiver takes control
My problem is how do we tell the receiver to return control OR how does the
receiver know when it is time to return control to the card and how does
wait for this control to come back.
I feel I'm missing a concept regarding setting up these system players to
Could any one please take me through the steps required...
Thanks in advance
