Using C++ VISA 3.6, I'm looking for a program to send a trigger from one controller and recieve it on a second controller. The program below
is a attempt to generate a external trigger and is not working.
Two problems
1) API Command viSetAttribute (instr, VI_ATTR_TRIG_ID, VI_TRIG_TTL0); does not support VI_TRIG_PANEL_OUT.
2) Using an example program below from NI, the code below does not send a trigger to the backplan line TTLTRG0* P2-A23
status = viOpen (defaultRM, "VXI0::0::BACKPLANE", VI_NULL, VI_NULL, &instr);
status = viSetAttribute (instr, VI_ATTR_TRIG_ID, VI_TRIG_TTL0);
status = viAssertTrigger (instr, VI_TRIG_PROT_ON);
getchar();
status = viAssertTrigger (instr, VI_TRIG_PROT_OFF);
getchar();
status = viClose (instr);
status = viClose (defaultRM);
