SETTING AN X-X CONNECTION

To connect two X channels, a Y channel must be used to establish a path, so two commands must be issued to

establish that path. To connect two X channels choose an unused Y channel then connect each X to that Y channel.

Using the Pickering Direct I/O driver:

The OPCrosspoint function takes row (Y) and column (X) as parameters:

PIL_OpCrosspoint(CardNo, SubUnit, 1, 2 ,1); // Set crosspoint at row 1, column 2 ON

PIL_OpCrosspoint(CardNo, SubUnit, 1, 3 ,1); // Set crosspoint at row 1, column 3 ON

Thus connecting X2 to X3 using Y1.

Using the Pickering VISA driver:

The SetCrosspointState function takes row (Y) and column (X) as parameters:

pipx40_setCrosspointState(vi, SubUnit, 1, 2 ,VI_ON);

pipx40_setCrosspointState(vi, SubUnit, 1, 3 ,VI_ON);

Thus connecting X2 to X3 using Y1.

Using the Pickering IVI driver:

There are two methods of achieving an X-X connection.

Method 1 – explicitly make a pair of X-Y connections:

pi40iv_Connect(vi, "x2", "y1")

pi40iv_Connect(vi, "x3", "y1")

Method 2 – use a configuration channel:

pi40iv_SetAttributeViBoolean(vi, "y1", PI40IV_ATTR_IS_CONFIGURATION_CHANNEL, VI_TRUE)

pi40iv_Connect(vi, "x2", "x3")
