Data format
Parity can be switched over from even even even even even to no no no no no
parity.
(note for VVO including version 2.15 even
parity is absolutely necessary)
Instrument number
Only relevant when operating two VEGACOM
557 on the same DISBUS. If two VEGACOM
557 are operated on DISBUS, different instru-
ment numbers have to be adjusted.
Not relevant for operation on LOGBUS.
Automatic Modem-initialisation
In position "ON“ the modem will be automati-

VEGACOM 557
A 6-pole DIL-switch block for adjustment of
the RS 232 PC-interface in the front plate is
located on the basic board.
Before inserting VEGACOM 557 in the carrier
or the housing, the DIL-switches have to be
adjusted to the user specific data. The data
of this adjustment come in to effect with the
next initialisation (voltage on).
