Non Fatal System Errors
Errors 60 through to 89 do not cause any loss of system functionality. They are logged only (for
service use).
Comms Channel A errors
60 Channel A Receiver Parity Error
This indicates a parity error was detected in one or more of the received message bytes.
61 Channel A Receiver Framing Error
Character was received for which no stop bit was detected.
62 Channel A Receiver Break Error
A steady low (space) signal has appeared at a receiver, indicating a break condition at the
transmitting end, causing this error code. The formal definition is that an all zero character with no
stop bit has been received.
63 Channel A Receiver Overrun Error
This indicates an overflow of the 3 byte FIFO buffer for a receiving channel. This means that the
processor is not reading the incoming data fast enough to prevent overwriting this stack.
64 Channel A Receiver Checksum Error
This error indicates the message received had a checksum error.
65 Channel A Receiver Data Error
Error 65 indicates the polling message received from the Console is an invalid type, i.e., a new
feature has been added to a console which is not yet supported, or the comms line has been
corrupted (in which case a checksum error will probably also occur).
66 Channel A Receiver Overflow Error
The message received was too long for the buffer, causing this error. This may happen if no EOM
character or sequence is detected.
67 Channel A Transmitter Overflow Error
The transmitter has tried to send a message which is too long. This means that the transmit buffer's
last position was reached, but an EOM character or sequence was not present.
68 Channel A Receive Timeout Error
This indicates that the receiver is expecting a character from the Console, but has not received one
for more than 1 second.
69 Channel A Transmit Timeout Error
This timeout error indicates that the transmitter is attempting to send a message to the Console,
but there has been a delay of more than 1 second since the last character was transmitted.
