Chapter 2 Function Reference — DIG_Out_Line
NI-DAQ FRM for PC Compatibles 2-180
©
National Instruments Corporation
Using This Function
DIG_Out_Line sets the digital line in the specified port to the specified state. The remaining
digital output lines making up the port are not affected by this call. If the port is configurable
and you have not configured the port as an output port, NI-DAQ does not perform the
operation and returns an error. Except for the PC-TIO-10, the DIO 6533 (DIO-32HS), the
VXI-AO-48XDC, E Series, or DSA device, you must call
DIG_Prt_Config to configure a
digital I/O port as an output port. On the PC-TIO-10, DIO 6533, VXI-AO-48XDC, E Series,
or DSA device, you need only configure the specified line for output using
DIG_Prt_Config
or
DIG_Line_Config.
Note
Connecting one or more AMUX-64T boards or an SCXI chassis to an MIO or AI
device causes
DIG_Out_Line to return a badInputValError when called with
port equal to 0 and line equal to one of the following values:
One AMUX-64T device—line equal to 0 or 1.
Two AMUX-64T devices—line equal to 0, 1, or 2.
Four AMUX-64T devices—line equal to 0, 1, 2, or 3.
An SCXI chassis—line equal to 0, 1, or 2 (and 4 for the E Series devices only).
