DAQ Hardware Overview Guide 8-2 www.ni.com
If you configure ports 0, 1, 3, 4, 6, 7, 9, and/or 10 for handshaking mode,
you cannot use ports 2, 5, 8, and/or 11 with the Digital I/O functions
because the device uses the digital lines in the latter ports as handshaking
lines for other former ports. For example, when you configure either port 0
or port 1 for handshaking mode, the device uses port 2 as the handshaking
lines, and you cannot use port 2 with Digital I/O functions. The criteria are
as follows:
• Port 2 (APC) is unavailable when you configure either port 0 or 1 for
handshaking mode.
• Port 5 (BPC) is unavailable when you configure either port 3 or 4 for
handshaking mode.
• Port 8 (CPC) is unavailable when you configure either port 6 or 7 for
handshaking mode.
• Port 11 (DPC) is unavailable when you configure either port 9 or 10 for
handshaking mode.
DIO-96 Groups
You can group any combination of ports 0, 1, 3, 4, 6, 7, 9, and 10 on the
DIO-96 to make up larger ports. For example, you can program ports 0, 3,
9, and 10 to make up a 32-bit handshaking port, or all eight ports to make
up a 64-bit handshaking port. See the Digital I/O Application Tips section
in Chapter 3, Software Overview, in the NI-DAQ User Manual for PC
Compatibles for more details.
