SCXI 1129

[Guy04]

In Switch Executive, how do you close the B0COMx to B3COMx relays and the AB0-AB3 relays in order to configure four SCXI 1129 matrixes as a 8x128 matrix.  Each one of the four 1129's are configured as a 4x64 matrixes.  Thanks for your help.

First if you connect (4) 4x64 matrix tothe back plane you will make a 4x256 matrix.

Assuming that is want you want to do, you need to create a route from r0 to com0 and a route from com0 to ab0 to connect r0 to the analog bus. Create the same two routes for row 0, 1, 2 and 3 of all 4 modules. Place all the routes in the a route group and connect this route group at the beginning of your application.

Thank you for your help. Can I use hardwires for these routes?

[Srđan_Zirojević]

I believe that you have to indicate that the analog buses are the same electrical connection, so that you can connect channels from one device to channels on another device. Therefore, you should create hardwires (or a bus) and put the ab0 through ab3 from every device on the bus.

I hope this helps.
