6.1 TNC error messages
Listed below are the error messages for data transfer, which are displayed at the TNC. In most
cases the messages are self-explanatory.
Error messages occurring only in ME mode:
WRONG MODE
TRANSFERRED DATA INCORRECT
WRONG PROGRAM DATA
ME: END OF TAPE
DATA CARRIER FULL
DATA CARRIER EMPTY
DATA CARRIER WRITE-PROTECTED
General error messages:
INTERFACE ALREADY ASSIGNED
Transfer is already taking place via interface, or data transfer has not been completed.
PROGRAM INCOMPLETE
Transfer has been interrupted or the file has not ended correctly (no END character or END block).
EXT. OUTPUT/INPUT NOT READY
Interface is not connected; peripheral unit is switched off of faulty.
TRANSFERRED DATA INCORRECT X
X can assume the values A to H, K or L (error codes).
The error message TRANSFERRED DATA INCORRECT N is displayed if, in the case of data transfer
with Block Check Character (BCC), a Not acknowledged (control character ) has been
received three times.
The remaining error codes (A to H) in this error message indicate that an error has been detected in
the received module. The error can have the following causes, with no assignment to the code
letters:
– Same baud rate not set at TNC and peripheral unit
– Parity bit wrong
– Incorrect data frame (e.g. no stop bit)
– Receiving module of interface faulty
Error code K or L is only displayed for transfer with standard data transmission protocol:
K: When an error was transmitted to TNC, character <1> not sent after the character.
L: The wrong error number was received after the error sequence <1>. (Error number
range: 0 to 7).
