Appendix A System Interface Description
(nur in englischer Sprache)
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.
