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 CONNECT­sockets 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 232­interface 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.

Note to example 4

If the inner resistance of the connected
processing is considerably smaller than
100 W (e.g. indicating instrument), the VBUS­signal superimposed to the 0/4 … 20 mA­output will be damped. With a low frequency
indicating instrument a load resistor of
R = 100 W must be looped into the
0/4 … 20 mA-line and the VEGACONNECT 2
must be connected to this resistor. On
analogue inputs of DCS-systems, this
resistor is normally ³ 100 W, so that no
damping occurs.
