Receive Serial Data
and up to four to Serial COP boards. Each connection can be monitored by setting the S1 DIP
switches as described below:
• To monitor data received from iBox, set DIP switches 1 and 4 = ON.
• To monitor data received from COP1, set DIP switches 1, 2 and 4 = ON.
• To monitor data received from COP2, set DIP switches 1, 3 and 4 = ON.
• To monitor data received from COP3, set DIP switches 1, 2, 3 and 4 = ON.
• To monitor data received from COP4, set DIP switches 1, and 5 = ON.
When the LEDs are ON they indicate the following:
• LED1: A non-STX character has been detected when an STX character was expected.
• LED2: An STX character has been received from the cartop.
• LED3: Data characters are being received from the cartop.
• LED4: A CRC character has been received.
• LED5: The CRC check indicates that good data was received.
• LED6: The CRC check indicates that bad data was received.
In normal operation, LEDs 2, 3, and 5 will glow faintly and LED 4 will blink roughly once every
40ms. If LED 1 or 6 is bright, bad data is being received from the cartop. This suggests that
there is a serial line quality problem.
Transmit Serial Data
• To monitor data transmitted to iBox, set DIP switches 2 and 4 = ON.
• To monitor data transmitted to COP1, set DIP switches 3 and 4 = ON.
• To monitor data transmitted to COP2, set DIP switches 2, 3 and 4 = ON.
• To monitor data transmitted to COP3, set DIP switch 5 = ON.
• To monitor data transmitted to COP4, set DIP switches 2 and 5 = ON.
When the LEDs are ON they indicate the following:
• LED1: The transmitter is in the RESET condition.
• LED2: The board is sending STX characters.
• LED3: The board is sending data characters.
• LED4: The board is sending CRC characters.
• LED5: The transmitter was busy when the board attempted to send data.
In normal operation, LEDs 2, 3, and 4 will glow faintly. If either LED 1 or 5 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-CTP board.
If LEDs turn on and stay on, the board is not functioning normally and should be reset (press
the RESET button). If the condition persists, there is likely a hardware problem on the board.
