VEGA Remote parameter adjustment and remote maintenance - Manual (Page 2)

1 Introduction
The configuration, parameter adjustment, operation and measured
value indication of all communication-capable VEGA instruments can
be carried out via the adjustment software PACTware with respective
DTM. Here, a PC is connected via an RS232, USB or Ethernet
interface to the respective VEGA insturment. If there are none of these
standard interfaces integrated in the respective VEGA instrument,
connection must be provided via the interface converter VEGA-
CONNECT.
Remote parameter adjustment means a connection between PC and
VEGA instrument via modem and public or private telephone network
instead of a direct cable connection. After the transmission path has
been set up via modem and telephone network, the adjustment with
PACTware is no different than with a direct connection via cable.
A modem connection is only possible via the standard RS232
interface. Hence, all involved instruments must have this interface.
With all VEGA sensors, connection is carried out via VEGACONNECT
3 (interface converter RS232 -> HART/I²C). A VEGACONNECT 4
cannot be used in conjunction with a modem. If the PC has no RS232
interface, an RS232-USB adapter can be used.
All external analogue modems with RS232 interface can be used. For
the PC and for short-term/mobile use on-site, the modems from US-
Robotics are recommended. If the option of remote parameter
adjustment should be permanent, we recommend on-site use of the
Phoenix industrial modem with top-hat rail mounting. All modems listed
here are available from VEGA.
Alternatively, a radio modem with RS232 interface can be used if a
telephone connection is not available. For this you need a SIM card
with deactivated PIN. In addition, the option 'Data transmission for
incoming connections' must be activated. The GSM radio modems
from Siemens (e.g. TC35i) have proven to be a good solution.
