Ribbon Cable Connections
CAUTION: Plugging in a ribbon cable the wrong way may damage the
cable or the circuit boards when power is applied. Reversing the ribbon
cable polarity of the cable from the iControl computer to the I/O card will
cause catastrophic failure of the iControl unit. Make sure the cables are
connected correctly.
The ribbon cables are keyed so that they can only be plugged in one way. If
the cables are not keyed, replace them as soon as possible with keyed
cables. I/O card replacements are shipped with a new cable.
The ribbon cables have a red or blue tracer that designates the pin1 side of
the cable. Plug the cables into the circuit boards with the tracer aligned with
pin 1 on the board. Pin 1 is designated by a 1 printed on the I/O board and
a square on the computer.
