INSTALLATION
2 - 7
1. Install a Parallel I/O board (refer to its user guide for installation
instructions). Be sure to assign it a Base Address.
2. Con
Þ
gure Terminal Block TB7 for the appropriate source of power
(see Section 2.2).
3. Set the Port Direction Switch (see Section 2.3).
4. Plug your selection of input/output modules into locations
KA0-KA7, KB0-KB7, and/or KC0-KC7.
5. Make external connections to the appropriate I/O terminal blocks
(TB1 and TB2 for Port A, TB3 and TB4 for Port B, TB5 for Port C/LO
and TB6 for Port C/HI).
WARNING
If using DC modules, observe the polarity markings at each
terminal location.
6. Install the Hold-Down Bracket.
7. Plug the Parallel I/O card into your computer and connect it to the
SSIO-24 with the appropriate cable. For the PIO-12, PIO-24,
uPIO-12, or uPIO-24 plug the C-18xx cable into SSIO-24 Connector
J1. For the PIO-96, plug the CACC-2000 cable into SSIO-24
Connector J2.
You are now ready to program the Parallel I/O card’s ports to
correspond with those on the SSIO-24. Be very careful to observe the
direction of the ports on the SSIO-24 (refer to the Port Direction Switch).
For example, if Port A on the SSIO-24 is set for INPUT, then Port A on
the Parallel I/O card must be set for INPUT.
WARNING
Setting corresponding ports on the Parallel I/O Card and
the SSIO-24 for opposing directions (Port A on the Parallel
I/O Card for input and Port A on the SSIO-24 for output)
could result in permanent damage to the Parallel I/O card
and the SSIO-24.
