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 2 computer to the I/O card will cause catastrophic failure of the PC I/O
card. 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 trace that designates the pin 1 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.
