Looking for VISA 2.6 equivalents for TrigAssertConf, MapTrigtoTrig, UnMapTrigtoTrig

[CMethods]

We are running Windows 2000, using a firewire controller (with GPIB), VISA 2.6, and VXI 3.2 installed.

We had been using GPIB-VXI, and we were using TrigAsstConf, MapTrigTrig, and UMapTrigTrig commands. Here is exactly what the calls were, and their meanings.

TrigAsstConf(0,2);
line 0 = TTL trig 0.
configmode 2 = binary 010 = Synchronize rising edge of CLK10, Pass trigger through asynchronously, and don't participate in SEMI-SYNC.

MapTrigTrig(42,0,0);
Src 42 = Front Panel In (unbuffered).
Dest 0: = TTL Trig Line 0.
Map Mode: 0 = no signal conditioning.

UMapTrigTrig(42,0);
Same description as above.

We found functions that are equivalent to the above listed function
s in NI-VXI 2.0 library, with pretty much the same options:
TrigAssertConf, MapTrigToTrig, UnMapTrigToTrig

But I can't find any information in the NI-VXI 3.2 help for TrigAssertConf, and VISA's version of MapTrigToTrig (viMapTrigger) does not have a match for the trigger source listed above. What are the VISA 2.6 equivalents?

Hello,

In VXI 3.2, TrigAssertConf does have help information in the NI-VXI API Reference. The only problem is that this specific function is not supported under NI-VXI 3.2. It was supported under 2.x, but it is not a usable function under the newer version, nor is there a VISA equivalent.

As far as the viMapTrigger, the only functionality that is availible under VISA are the options that you see. There are some things that VISA is unable to do, and that option is one of them. Your best solution right now would be to stay at NI-VXI version 2.0.

Thanks for the reply. We have to use NI-VXI 3.2 to run a firewire controller. Is there going to be support for these functions in the future?

Lee,

Yes, there will be support for these functions in the future. The next driver that will support these functions should be out in Q2 of this year. I recommend that you periodically look at our website around that time and check to see if the new version is availible.
