Gx6192/Gx6256/Gx6864RtmMatrixGetChannel

Returns a rear transition board Matrix relay's state

Gx6256RtmMatrixGetChannel (nHandle, nChannel, nGlobalBusLine, pnState, pnStatus)

Name	Type	Comments
nHandle	SHORT	Handle to a GX6256/GX6864/GX6192 board.
nChannel	SHORT	Instrument channels (0-31)
nGlobalBusLine	SHORT	Global Bus line (0-15)
pnState	SHORT	Returns the state of a rear transition module matrix relay
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

The rear transition module contains a matrix that connects instrument inputs to global bus lines (on the backplane).

The following returns the state of channel 5, global bus line 15 connection state:
