6-88 Manual # 42-02-7223
Normal Operation The normal operating condition is with all DIP switches OFF. This
gives the normal operation display as follows:
When the iBox is not active, only LED 5 will toggle. When the iBox is active and normal opera-
tions are in progress, LEDs 1, 4 and 5 will toggle regularly.
Firmware Download Firmware updates can be downloaded via iView. Please refer to
“To close the dialog, click the “X” in the upper right corner.” on page 9-182. Normally, no man-
ual intervention is needed at the cartop. However, if a problem does develop, the following may
be of use in recovering:
1. Set the S1 DIP switches 1, 6 and 8 = ON.
2. Press the manual Reset button on the ICE-CTP board. This tells the cartop firmware to
wait for a firmware download without attempting to run the normal cartop application
first.
3. Perform the firmware update using iView (File > Firmware Update).
Board Version The version and revision of the ICE-CTP board can be determined using
the DIP switches and LEDs 1 through 6 (ignore LEDs 7 and 8) The values are in hexadecimal,
with LED1 bring the 2
0
bit. For example, if the number were “01”, LED 1 would be ON and LEDs
2 through 6 would be OFF (LEDs 7 and 8 are not part of the value and must be ignored).
• DIP switch 3 = ON, all others = OFF: Major version number displayed on LEDs.
• DIP switch 2 = ON, all others = OFF: Minor version number displayed on LEDs.
• DIP switch 1 = ON, all others = OFF: Revision number displayed on LEDs.
Table 6.9 Diagnostic Indicators (Normal Operation - All DIP Switches OFF)
LED Description
1 Represents message input from iBox to iLink. With proper communication, toggles approx-
imately every 80mS. Goes OFF and stays OFF if input is lost.
2 Indicates that the cartop detected an unintended motion safety fault. With the car on Pas-
senger operation, after the car had reached a landing, the car moved at a speed greater
than 150 feet-per-minute.
3 Indicates that the cartop detected an unintended motion safety fault. With the car on
Inspection, after the car had reached a landing, the car moved with doors open.
4 Message output from iLink to iBox. With proper communication, toggles approximately
every 80mS. Goes OFF and stays OFF if output is lost.
5 This is the “alive” indicator. It toggles every 80mS during normal operation.
6 Lights when the car is on Inspection mode.
7 Unused.
8 Indicates that an interrupt is being serviced. If it goes off and stays off, the board is not
functioning normally and should be reset (press the RESET button).
