ICE-CTP Cartop Diagnostics

There are eight diagnostic LEDs on the CTP board inside the iLink enclosure. On power up or
reset, these LEDs will light sequentially, first in one direction, then the other, after which they
will briefly clear.

being serviced. In normal operation it turns on and off quickly enough that it is almost as bright
as a fully illuminated LED. If LED 8 stays OFF, it indicates that the board is not functioning
normally and should be reset (press the RESET button).
Note
If there is a problem with communication between the iBox and the CTP board after initial
installation, verify that the iBox TX+ and TX- terminals are connected to the CTP board RX+
and RX- terminals, and the iBox RX+ and RX- terminals are connected to the CTP board TX+
and TX- terminals
Manual Reset
reset and startup.
• When the reset button is release, the LEDs will light up one at a time in the following
sequence - (1, 2, 3, 4, 5, 6, 7, 8, 7, 6, 5, 4, 3, 2, 1). Normal operation should commence
immediately following the reset sequence.
If the reset sequence consists of three iterations of all LEDs on at the same time followed by all
LEDs off, the board has been programmed with a non-production version of firmware. The
board should be reprogrammed.

switches firmly in the appropriate direction when setting the switches. The use of a small screw-
