1. General
The universal LAN-Modem (Local Area Network) UniMod Ethernet was developed for remote in-
quiry of measured data of any kind, especially however for telemetering applications.
For the UniMod Ethernet communication, modules produced by internationally renowned compa-
nies are used. These companies update their software packages regularly and add or change fea-
tures. The software releases are continuously checked by the development department, but no
responsibility for these software releases can be taken except of warranty granted by the module
producer.
2. Power Supply Unit
The modem is equipped with a built-in, low-loss switched power supply, which enables operation in
a wide-range of AC or DC supplies:
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:
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
on, if the modem has connected (LAN network connected)
DCD-LED
on, if the modem has built a data link to remote station (TCP/IP connection)
TxD-LED
on, if data are transferred from the target device to the modem
RxD-LED
on, if data are transferred from the modem to the target device (e.g. meter)
5. Installation Hints
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!
