Comms Error Codes

The "Comms CAN x Diagnostic" and "Comms RS232 Diagnostic" channels

seen can be used to diagnose communications problems.

Multiple errors are shown by error codes added together. For example: A

RS232 error of 9 = parity + overrun.

The error values have the following definitions:

RS232 Errors

Errors generated by RS232 communications.

1 PARITY Parity bit incorrect. The comms parity setup is

wrong, or there is electrical interference

causing errors in the data.

2 FRAMING Not seeing the stop bit. The baud rate or stop

bit setup is wrong or there is electrical

interference causing errors in the data.

4 NOISE Glitch in the data. Electrical interference is

causing glitches in the signal. (C185 does not

generate this error)

8 OVERRUN A byte was received before the previous byte

was read indicating that the processor was too

busy to read the message.

512 NO DATA A valid message header was not found - either

there is a wiring fault or comms is setup

incorrectly.

1024 CHECKSUM A valid message header was found, but the

checksum was wrong. If seen in combination

with other errors there is electrical noise. If only

checksum errors occur there may be a

software incompatibility between the C185 and

the other device.

2048 WRONG DATA Could not decode the protocol.

General CAN Errors

Errors generated by general CAN communications.

2 FRAMING Only generated when used with an

E888/E816 expander. Inconsistent message

length.
