Purpose
Disconnects a device signal from the specified RTSI bus trigger line.
Parameters
Input
Parameter Discussion
sigCode is the signal code number of the device signal to be disconnected from the RTSI bus
trigger line. Signal code numbers for each device type are in the RTSI Bus Trigger Functions
section of Chapter 3, Software Overview, of the NI-DAQ User Manual for PC Compatibles.
trigLine specifies the RTSI bus trigger line that is to be disconnected from the signal.
Range: 0 through 6.
Using This Function
RTSI_DisConn programs the RTSI bus interface on the specified deviceNumber such that
NI-DAQ disconnects the signal identified by sigCode and the trigger line specified by
trigLine.
Note
It takes the same number of RTSI_DisConn calls to disconnect a connection as it
took
RTSI_Conn calls to make the connection in the first place. (See RTSI_Conn
for further explanation.)
