ESTEEM COMMUNICATION ERROR MESSAGE TABLE
Listed below are the ESTeem Communication Error Messages and their definitions. To receive these messages, TYPSYSTEM must be ON (See
APPENDIX E, DEFINITIONS). All System Status Messages have a bell (O7H or CTRL G) preceding the message except when Messform is ON.
If Messform = OFF Line A will be displayed. If Messform = ON Line B will be displayed.
1. A "RS-232 RX PARITY ERROR"
BECO1
This message is displayed when there is a mismatch between
the received characters' parity and what the ESTeem's parity is
set for.
2. A "RS-232 RX OVERRUN ERROR"
BECO2
This message is displayed when the ESTeem's central
processor unit fails to read an RS-232 character from the data
buffer while more than three characters have been received.
The third character is lost due to the fourth character being
stored in its place.
3. A "RS-232 RX FRAMING ERROR"
BECO3
This error message has been deleted. See Section 6, T/E LED.
4. A "HDLC RECEIVE OVERRUN ERROR"
BECO4
This message is displayed when CPU does not service an
incoming packet fast enough and information is lost. This error
message should not occur under normal situations unless
internal processor has a failure.
5. A "HDLC RECEIVE CRC ERROR"
BECO5
This message is displayed when the Cyclic Redundancy
Check (CRC) byte does not coincide between transmitting and
receiving ESTeems. This can be caused by the integrity of the
data being compromised during transmission.
6. A "HDLC RECEIVE RESTV SEQUENCE ERROR"
BECO6
This message is displayed when the internal received
sequence number does not match the received packet received
sequence number.
7. A "HDLC RECEIVE SESTV SEQUENCE ERROR"
BECO7
This message is displayed when the internal send sequence
number does not match the received packet send sequence
number.
8. A "NOVRAM FAILED TO VERIFY"
BECO8
This message is displayed when a SAVE command is invoked
and the verify read on the NOVRAM fails.
9. A "NOVRAM FAILED"
BECO9
If this response is received after a save, save 1 or a save 2,
there is a hardware problem with the ESTeem's NOVRAM
CIRCUITRY.
1O. A "HDLC MISSING SYNC BYTE"
BEC1O
This message is displayed when a version 2.O software is
trying to communicate with a version other than 2.O.
11. A "SYSTEM CLOCK FAILURE"
BEC11
This message is displayed upon failure of the ESTeem internal
clock.
12. A "INVALID MANCHESTER DATA"
BEC12
This message is displayed upon receipt of invalid manchester
