Section VII Modem data transfer
1. Introduction
Modem data transfer enables remote handling of the instrument and its data. When the
instrument has to be located on distant or hardly accessible place, the modem is the
only practical solution for fast access to the instrument. It is only necessary to connect
modem to the instrument at the location where measurements are performed and
activate modem control. The instrument and modem are connected via RS232
interface.
Requirements for the instrument and modem interface:
Equipment PC SW min. ver. Firmware min. version
Power Harmonics Analyzer MI 2092
Power Link 4.0 Ver 5.00 + modem option
Power Quality Analyzer Plus MI 2292
Power Link 4.0 Ver 5.00
Minimum requirements for PC:
- PC Pentium, Windows 98 or higher
2. Modems
It is possible to use a range of standard (analog) and GSM modems with a PC and the
instrument.The following table shows possible combinations for remote measuring
system:
On PC side On measuring place
Standard (analog) internal modem
Standard (analog) external modem
GSM terminal modem
GSM terminal modem or
Standard (analog) external modem
All PC external modems and modems for the instrument must have RS232 interface.
GSM modem connected to the instrument needs a PIN card with included DATA
number (VOICE number is included by default but it is not needed). Please contact your
GSM provider for the DATA number.
Application described in this manual is based on ‘Siemens TC35 GSM terminal’ modem
and ‘US Robotics – Faxmodem’ standard (analog) modem. For a third party modem
device, apply appropriate settings as required by modem vendor.
We recommend preparing a test system for verification and training before performing
actual measurements at the remote place.
