1.5 SAM-242 Card Connections
The input and output and connectors on the SAM-242 card are identical to those on the
SQM-242 card.
Input Connections
BNC cables connect the SAM-242 input to the signals to be measured. The SAM-242
accepts input voltages /- 10VDC.
C
AUTION
: The BNC connector shield of each SAM-242 input is connected to a common
analog ground. Input signals to the SAM-242 must be /-10V DC and share a
common ground. Failure to observe this constraint can result in damage to your
equipment and/or the SAM-242 card,
Output Connection
The SAM-242 outputs are identical to the SQM-242. See the previous section for
hookup instructions.
1.6 Digital I/O
The SQM-242 card and SQM-242 CoDep software do not support the digital I/O
required to automatically open and close shutters, rotate source pockets, etc.
Sigma's optional SQS-242 CoDeposition software adds this capability to the SQM-242
card. Using an inexpensive PLC, the SQS-242 software provides virtually unlimited
digital I/O capabilities.
Contact Sigma Instruments for more information on interfacing the SQM-242 card to
your system's digital I/O.
