Appendix

RS232/485 interface

Options for using the serial interface include transparent data transfer, control of
connected devices or operation of the unit with a terminal program. Depending
on the setting, the interface works with the RS232 or RS422/485 protocol. The
protocol used depends on the current configuration (see page 55).
The serial interface on the VIP 10 uses a Sub D connector and the VIP 1000 uses
an RJ45 connector.
