Appendix A System Interface Description

There are two system interfaces:
 Serial interface with RS-232C or RS-422 support
 Parallel Centronics interface.
The interfaces can be operated in three different modes:
parallel interface active
parallel interface active in shared mode with serial RS-232C
parallel 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 possible only when the
interface buffer is completely empty of data.
