ICE-COP Board Diagnostics

The DIP switches and LEDs in the upper right corner of the ICE-COP
board provide diagnostic information. Note: The DIP switches must
be in the fully ON or fully OFF position to function reliably. Be sure to
push the switches firmly in the appropriate direction when setting the
switches. The use of a small screwdriver of ballpoint pen is recom-
mended.
LED 1
Regardless of the switch settings, LED 1 is ON when an
interrupt is 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 1 stays OFF, it indicates that the board is not functioning nor-
mally and should be reset (press the RESET button).
Manual Reset
the same meaning during reset and startup.
• When the reset button is held down, all LEDs should illuminate.
• When the reset button is released, the LEDs will light up one at
a time in the following sequence - (8, 7, 6, 5, 4, 3, 2, 1, 2, 3, 4, 5, 6, 7, 8). 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.
Normal Operation
gives the normal operation display as follows:
• LED4: This is the "alive" indicator. It should toggle every 40ms.
• LED5: Toggles when a block of data is sent to the cartop, approximately once every 50ms.
• LED8: Toggles when a block of data is received from the cartop, approximately once every
50ms.
When the cartop is not active, only LED4 will toggle. When the cartop is active and normal
operations are in progress, all three LEDs will toggle regularly.
