As EFD300-telegrams cannot be distinguished in monitoring or control direction the direction has to be parameterized in LIAN. You can also set whether at the beginning of a message a start pulse of 100 msec or a long sign should be transmitted/received.

Transmission errors

*F:Blocklength : The telegram length is incorrect
*F:Hammingcode : Check code is incorrect.
*F:TimeTolerance :   The measured character length is beyond the tolerance set in LIAN.
*F:Spike :   The received sign is smaller than 20 % of a short pulse
*F:GroupedChar : More than one grouped character.
*F:OrganizationChar : The BE-bit is equal to the BA-bit (command).
*F:SelectionChar : More than one selection character (command).
The last two error checks are not done with the general check.
