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!

6. Programming the Modem
Before installing the modem it has to be programmed in order to meet the demands. The baud rate
and data format for connecting the target device (e.g. meter), the transmission mode as well as
transmission rates must be adjusted. At delivery status the following default parameters are set:
Baud rate: 9600 Baud (if not mentioned otherwise)
Data format: 7, Even, 1 (if not mentioned otherwise)
S0=1: This parameter setting determines the number of rings (here 1) before automatic
answering
&D0: This parameter determines how the modem responds when circuit 108/2 (DTR) is
changed from ON to OFF during data mode. With setting 0 the modem ignores DTR
&K0: No local flow control
E0: This setting determines whether or not the modem echoes characters received
from PC during command state (0 = no echo)
Q1: This parameter setting determines whether or not the modem transmits any result
code to the PC. Information text transmitted in response is not affected by this set-
ting (1 = result codes suppressed)
DTC=60: Data transmit control (connection check) active: 60 seconds
Keep Alive=0: TCP/IP-Line check
PORT=1234: Standard port number = 1234
This configuration allows for reading meters of type VDEW (IEC1107 / IEC62056-21). If you want
to change this parameters, a PC with terminal software (e.g. UniModSet, Windows HyperTerminal
etc.) is needed. Moreover, experiences with the Hayes AT modem command set are highly rec-
ommended. To establish connection between PC and modem you have to use:
A) the parametering adapter with USB port (#12823)
B) the parametering adapter with RS232 port (#9177)
C) the converter (converter box or ConvBox) to adapt the interfaces (#12685)
Description of the connection options:
A)
The parametering adapter with USB port (Micro-USB
Type A or B), which can be plugged instead of an
interface module. This adapter can be ordered as
accessory (Order No.: #12823).
1. First connect the adapter with the USB port at the PC and wait for confirmation. The new COM-
Port can be find in the device manager (Control Panel): USB Serial Port (COM…).
2. Then disconnect the modem from the supply (important!) and remove carefully the interface
module.
3. Now you can plug the parametering adapter into the 7-pole jack (the LED’s must point downwards).
4. The UniMod Ethernet can now be programmed with the software UniModSet.
5. After programming switch off the UniMod and insert the interface module carefully again.

B)
The parametering adapter with RS232 port, which can be
plugged instead of an interface module. This adapter can be
ordered as accessory (Order No.: #9177).
1. First disconnect the modem from the supply
(important!) and remove the interface mod-
ule.
2. Set the switch to left position "01L", as
shown in the picture:
Position "01L/GSM".
3. Insert the 7 pole plug of the parametering
adapter instead of the interface module. The
notch must point upwards.
4. Then connect the 25 pole plug (RS232) to
the PC port and switch on the voltage supply
at the modem.
5. The UniMod Ethernet can now be programmed with the software UniModSet.
6. After programming switch off the UniMod and insert the interface module carefully again.

Programming with the software UniModSet/MetcomTSet
After program start, select the register tab “Ethernet”. Then choose one of the standard configura-
tions („Assign“, for E-Meters, Metcom MWT32, M-Bus-Systems or DLMS) or assign the following
parameters manually:
Baud rate, e.g.: 9600 Baud
Data format, e.g.: 7E1
Control, e.g.: ignore DTR, no handshake
Responses, e.g.: as text or numbers
Function: Box to Box Client or leased line between two modems
IP-Address (and port number)
Gateway
Subnet-Mask
Data transmit control
Keep alive
For the network parameters ask your system administrator. Then select in the menu „Settings -
Interface“ the serial port (e.g. COM1) and send („Write“) the chosen device configuration to the
UniMod Ethernet. Additionally you can receive („Read“) the configuration from a connected UniMod
Ethernet.
In the menu „File“ the current configuration can be saved („File save as...“).
An existing configuration can be loaded by means of „File load“.
Further it is possible to set the Ethernet (LAN) parameter.
Experienced users can alter the device configuration with the internal terminal program using AT
commands.

Programming with the terminal software
First set your terminal program to the appropriate data transmission rate and data format for read-
ing the target device (i.e. meter). Use one of the AT commands (e.g. ATS0?, ATI, AT&V) to check
whether the modem answers. If you see the answer on the screen, the interface is working cor-
rectly.
Note: Simply typing „AT“ does not result in an answer, because the modem is by default pro-
grammed not to send messages and echoes (Parameters ATQ1 and ATE0).
At the end of every programming the settings have to be saved permanently using the AT&W
command. This ensures that the parameters are restored after power failure.
Find below some examples of AT commands (the answers depend upon the respective firmware
version):

at&w
No answer because of atq1
Saves the current parameter setting in the user-
defined profile. This settings are active after every
resumption of power supply!
Attention: At the end of every programming the settings have to be saved permanently
using the at&w command. This ensures that the parameters are restored after
power failure.
Example:
Establish connection PC to modem (e.g. using the parameterization adapter). Start the terminal
program and set data rate correctly.
The modem does not reply to a simple "AT" command by default. In order to test communica-
tion you have to use a command which results always in an answer (e.g. "AT&V" displays the
actual configuration). This should enable a readable output on your screen.
Input "AT&F" to restore factory settings. Modem should reply "OK".
Select automatic answering: "ATS0=1", Modem reply: "OK".
DTR-control is ignored: "AT&D0", Modem reply: "OK".
Disable local flow control: "AT&K0", Modem reply: "OK".
Disable echo: Enter "ATE0", Modem reply: "OK".
With this setting the modem does not echo characters sent by the target device. Some meters
may not communicate correctly if they receive their own output.
Suppress modem result codes: Enter "ATQ1". No answer from modem.
This prevents the modem from sending result codes to the target device. The result codes can
cause trouble with some meters.
Save current parameters: Enter "AT&W". No answer if ATQ1 command has been issued be-
fore.
Parameterization finished.
Dial
The modem picks up and dials in accordance with the dialing string given by the ATD command,
e.g.: ATD192.168.1.220:1234
Disconnect
After the escape sequence +++ the modem hangs up.
Data Transmit Control (DTC)
Data transmit control is a firmware integrated feature for supervising the online data transfer. The
feature prevents the modem from staying online infinitely, even if no data are transferred at all.
An arbitrary time span from 10 to 255 seconds (by 10 seconds steps) can be programmed. DTC is
disabled if the time is set to 0 (default value). If the value is not 0, the time counter starts running
immediately after the connection is established. As soon as it is run out the modem is reset, which
causes it to hang up.
The time counter is reset by every transmitted or received character. That means, the modem
holds the line for <n> seconds after the last transmitted or received byte, where <n> is the setting
of DTC.
Keep Alive
Keep alive is a firmware integrated feature for supervising the TCP-IP network line. The feature
prevents the modem from staying online infinitely, even if the LAN network don’t work.
An arbitrary time span from 10 to 2550 seconds (by 10 seconds steps) can be programmed. Keep
alive is disabled if the time is set to 0 (default value). If the value is not 0, the keep alive probes will
be send every x seconds. As soon as it is run out the modem is reset, which causes it to hang up.

Telnet access
For purposes of service it is possible to access an UniMod Ethernet via the Telnet tool, which is
delivered with Windows. You can start it using the “Execute” button in the Start menu, or by enter-
ing “telnet” in a DOS box. Help is offered by typing “help” at telnet’s command prompt.
Procedure:
Open connection ( “open <UniMod IP address>”)
Read current modem settings using AT commands (e.g. AT&V). Please note that the “AT”
part is already printed, only the following command specifier must be entered.
The command ATZ resets the modem.
Starting with version „ETHERNET V3“ (can be queried using ATI command) access must be ena-
bled by entering username and password. Default values are “insys”/”insys”. In this version the
modem-reset must be requested using AT#RESET, the ATZ command is functionless.
7. Reset Function
Optional it is possible to activate the time-controlled modem-reset. The functionality is activated by
the jumper and displayed by the Rst-LED (Rst-LED flashes every 10 seconds).
