Appendix A System Interface Description

There are two system interfaces:

Sone serial interface with RS-232C or RS-422 support

Sone Parallel Centronics interface.

The interfaces can be operated in three different modes:

Sparallel interface active

Sparallel interface active in shared mode with serial RS-232C

Sparallel interface active in shared mode with serial RS-422

The following chapter gives an overview about interface characteristics, control signals, protocols, and cabling.

Any change to the operation mode (PARALLEL, PARALL. / RS232, or PARALL. / RS422) and to the size of the interface buffer is only possible when the interface buffer is completely empty of data.
