SCXI-1166 SPDT GP Relay, how to program in NISE and Teststand

[Guy04]

Hi,

I have a SPDT GP relay and I wanted to know how the routes should be created.  For example, in NISE when you create a route you have two endpoints.  Endpoint1= Comx but what should Endpoint2=?.  Should it be:

Endpoint2=ncx  or

Endpoint2=nox

Lets say the route name is called "MyRoute".  If I chose my Endpoint2 to be "nox" then when I go into Teststand and use the "Switching tab" under Properties and say Connect "MyRoute" then the connection should be between "Comx->nox".  Now when I say Disconnect "MyRoute" will this cause the connection to be "Comx->ncx"?

Thanks for your help in advance.

Guy,
NISE communicates with switch devices through an IviSwtch-compliant drivers, based on the IviSwtch class specification.
This specification does not prescribe the behavior for form C relays - the only way to ensure that the normally-closed position is connected is to create two routes and call connect on the other one after calling disconnect on the first one. Complicated, but that's the only way to ensure the behavior across switches that may behave in different ways.
