Board Version
The version and revision of the ICE-COP board can be determined using
the DIP switches and LEDs 3 through 8 (ignore LEDs 1 and 2) The values are in hexadecimal,
0
with LED8 bring the 2
LEDs 3 through 7 would be OFF (LEDs 1 and 2 are not part of the value and must be ignored).
• DIP switch 6 = ON, all others = OFF: Major version number displayed on LEDs.
• DIP switch 7 = ON, all others = OFF: Minor version number displayed on LEDs.
• DIP switch 8 = ON, all others = OFF: Revision number displayed on LEDs.
Receive Serial Data
LEDs are ON they indicate the following:
• LED3: The CRC check indicates that bad data was received.
• LED4: The CRC check indicates that good data was received.
• LED5: A CRC character has been received.
• LED6: Data characters are being received from the cartop.
• LED7: An STX character has been received from the cartop.
• LED8: A non-STX character has been detected when an STX character was expected.
In normal operation, LEDs 5, 6, and 7 will glow faintly and LED 4 will blink roughly once every
40ms. If LED 3 or 8 is bright, bad data is being received from the cartop. This suggests that
there is a serial line quality problem.
Transmit Serial Data
ON they indicate the following:
• LED4: The transmitter was busy when the board attempted to send data.
• LED5: The board is sending CRC characters.
• LED6: The board is sending data characters.
• LED7: The board is sending STX characters.
• LED8: The transmitter is in the RESET condition.
In normal operation, LEDs 5, 6, and 7 will glow faintly. If either LED 4 or 8 comes on and stays
on, the board has malfunctioned. If a manual reset does not clear the problem, there is a hard-
ware problem on the ICE-COP board.
