1. General
The universal analogue/PSTN (Public Switched Telephone Network) modem UniMod 01/I is sup-
posed for remote inquiry of measurement data of any kind, especially however for telecounting
applications.
For the UniMod 01/I communication modules produced by internationally renowned companies are
used. These companies update their software packages regularly and add or change features. The
software releases are continuously checked by the development department, but no responsibility
for this software releases can be take over except of warranty granted by the module producer.
2. Power Supply Unit
The UniMod 01/I modem is equipped with a built-in, low-loss switched power supply, which enables
it to operate on a wide-range AC or DC supply voltage:
80VAC to 270VAC
or 60VDC to 375VDC
3. Interfaces
The interface for connecting the target device can be specified by plugging the appropriate inter-
face module. The following module types are available now:
CS (20mA current loop) interface module, active (supplies current) or passive
RS232 interface module (uses signals RxD, TxD, CTS, RTS, GND, DTR, DCD/DSR)
RS485 interface module
M-Bus interface module, active (can supply 20 devices max., 10/old version)
Communication is possible with many standard protocols, like SCTM, LSV1, DLMS, IEC1107,
IEC60870 (transparent reading) etc.
4. Display
The following LEDs display the current operating status of the modem and give information about the
data transfer.
Operate-LED
signals, that the modem is supplied with power.
Rst-LED
flashes, when the reset function is active.
Hook-LED
lights, when the modem has connected.
DCD-LED
lights, when the modem has built a data link to remote station.
TxD-LED
lights, when data is transferred from target device to modem.
RxD-LED
lights, when data is transferred from modem to target device (e.g. meter).
5. Installation Hints
Although the UniMod 01/I is equipped with an insulating plastic housing, it is approved protection
class 1 and MUST therefore be connected to protective earth (PE).
The installation must be done in a way, that even in the case of cable break no dangerous voltages
are applied to touchable parts of the device including the antenna. This can be accomplished e.g.
by using cable ties and appropriate shortening of the cables.
Attention: NEVER remove the interface modules when the device is powered!
