Operating instruction
1 Product description
1.1 Function and configuration
VEGACONNECT 2 is an interface cable
(interface adapter) between communication
capable VEGA-instruments (VEGASON,
VEGAPULS, D-series, VEGABAR,
VEGAMET) and a PC in conjunction with the
adjustment software VEGA Visual Operating.
It is connected via a 9-pole SUB-D socket to
the standard interface of the PC and via
2 mm-plug (2-wire line) to the CONNECT-
sockets of the VEGA-instrument.
Further connection possibilties for the 2-wire
line of VEGACONNECT 2 are:
- the connection line between VBUS-sensor
and signal conditioning instrument
- the 0/4 … 20 mA-signal line of the K
(compact)-versions of the sensors.
VEGACONNECT 2 is located in a rugged
plastic housing and is supplied completely
with connection lines and plug connections.
The voltage supply is made via the RS 232-
interface of the PC.
For operation of VEGACONNECT 2 the
adjustment software VEGA Visual Operating
(VVO) version 2.20 or higher is necessary. It
is installed on the PC under WINDOWS 95
and ensures comfortable configuration and
parameter adjustment of communication
capable VEGA-instruments.
A communication with HART ®- -protocol is
possible. Hence HART ®- -capable VEGA-
instruments can be adjusted with the PC and
the software VVO.
