© National Instruments Corporation C-3 653X User Manual
Note
In Figure C-1, the * indicates that you can reverse the pin assignments of the ACK1
(STARTTIG1) and REQ1 pins, or the ACK2 (STARTTIG2) and REQ2 pins. To do this, set
the
ACK-REQ Exchange
attribute to ON in the DIO Parameter VI in LabVIEW or in
set_DAQ_Device_Info
in NI-DAQ. This allows you to perform handshaking I/O
between two 653X devices using an SH-68-68-D1 cable.
Use Table C-2 to find the accessories designed for connecting signals to
your 653X device.
Signal Descriptions
Use Table C-3 to find the function for each signal, which is based on the
