Note. The minus sign next to the signal indicates asserted state is the low voltage of the two levels used for
logic signals.
*CAUTION: Connector contact 25 must not be connected to ground at the host end of the cable. If the I/O
cable should accidently be plugged in upside down, terminator power on pin 26 will be shorted to
ground.
