2.3 External connections

2.3.1 Interfaces and connectors

2.3.1.1 GSM antenna connector

SMA antenna connector placed on front panel is used to connect external GSM. To
establish connection with GSM network an external antenna must be used. Type of antenna
depends on GSM coverage. In good circumstances (level of received signal is high) use antenna
which is attached in the package. If range of GSM is low or none, an outdoor
directional/omnidirectional or indoor (for instance in place where GSM range is sufficient)
antenna should be used.

Note: If there is no antenna connected to SMA connector, the connection with GSM
network is impossible.

2.3.1.2 Modem serial port, either full RS232/RS485

Serial RS232/RS485 (through RJ-45 connector) is placed on front panel of modem and
it can be configured for special use as an option for customer.

RS485 line termination

In case a long RS485 line, the line should be terminated on both ends. It can
be realized by using an external terminator or by RT signals short-circuit (pins 1 and 3 of RJ45
connector for RS485 device option). The build-in terminator assumes 120Ω line impedance.

2.3.1.3 RJ-45 connector

RJ-45 connector is placed on front panel of RB-MTX modem and used for
communication with PC or laptop to plug cable for Ethernet. In order to start configuration
pages of modem plug UTP cable between RJ-45 of modem and RJ-45 of your computer.
Configuration pages are available in the web browser under IP address specified on the
modem (default address is 192.168.1.234).

8

2.3.1.4 Power supply connector

In the RB-MTX modem power supply 6V..30V care must be taken to ensure “clean”
power supply input and especially to avoid short transients on power supply lines originating
from inductive load switching. Otherwise internal module (G24, H24 or HE910) may be
permanently damaged.

2.3.1.5 Audio I/O

Audio Input and Output lines are available as option. There are three lines available:

 SPK/LINE OUT – external speaker or line out
 LINE IN
 MIC IN –microphone plug

2.3.1.6 20-pin connector

RB-MTX is available with 20pin connector as an option. Detailed description is shown
below.

2.3.2 SIM card holders

SIM card holders are placed in front panel of RB-MTX. To insert SIM card into the
extractable holder push yellow button and take holder out. Place SIM card as show in the
picture. To operate the module in a GSM network, it is necessary to insert at least one SIM card
obtained from the network operator.

4.1.1 Inserting SIM card(s)

 Push yellow button place on front panel and take SIM holder drawer out.
 Place SIM card(s) in the holder(s) as shown in the picture:

*modems are available with one or two SIM cards

 Plug UTP or similar cable to RJ-45 plug.

13

4.2 Modem configuration

Modem is configured via web browser making it portable and easy to use. Modem
configuration is described below in following sections. Modem settings are divided into
sections which allows user to easily find option needed. When switching tabs settings are
automatically saved in modem cache, to save settings permanently and apply them click Save
Settings in menu. You can also discard changes by choosing appropriate option from the
bottom of the menu.

WARNING: Cache is cleared on modem reset or pulling the power cable out.

WARNING: Not all tabs are available on every modem version.

4.2.1 Setting up the connection

After you connect all necessary cables (see Setting up the modem Setting up the
modem) you can set up connection. Connect UTP cable to your computer and go to Internet
protocol TCP/IP properties (Network connections -> Local Area Connection ->Internet
protocol TCP/IP-> Properties) and set your IP address as 192.168.1.x. Now modem will
connect your computer and its configuration page can be seen by going to default IP address
in your browser 192.168.1.234.

4.2.2 Modem status page

Go to your web browser and put IP address 192.168.1.234. You will be asked for
username and password. By default it is:

Username: admin

Password: 12345

If everything is configured correctly you should see following screen:

This is Status page of your modem. Here
you can see if modem is
connected/disconnected from net and its
parameters and parameters of PPP connection.

14

4.2.3 Local network

On LAN configuration page you can find essential parameters needed for LAN
connection. Here you can set IP Address (or set it to be downloaded via DHCP), mask, default
gateway, DNS addresses. Last two options can be entered manually or downloaded
automatically via GSM or DHCP. Modem can also work as DHCP server-you can define its range
and set list of IP-MAC binds.

15

4.2.4 GSM network

On ISP Master page you can define internet connection parameters (APN, username,
password, CSD, ISP IP and Modem band) for one or two SIM cards (depending on modem
version). To use internet you should know those parameters - they are essential for getting
access to internet. The parameters should be ensured by your mobile network provider. You
can find them by contacting your GSM network provider or visiting its website.

To enter the PIN for SIM card you need to mark “Enable” field and then fill the field
below with correct PIN. Outgoing calls are made always on MASTER SIM card.

16

4.2.5 Connection control

Here you can set parameters of switching between two SIM cards. You can define time
for ping and ping counter for 4 IP addresses you choose. In example (picture) here after 3
pings that take 10 seconds each card will change from Master to Slave or opposite.

17

4.2.6 Ports configuration

You are able to set port settings under RS232 Port page. There are 3 configurable ports:
/dev/ttyS0, /dev/ttyACM0 and /dev/ttyS1 or /dev/ttyUSB0 (depending on modem version).

Every port can be set to different mode. On /dev/ttyS0 you can set terminal, ModBus
gateway or NTRIP mode. Two other ports can work as modem port (modem control and
modem data) or SMS receiving port (see also: SMS Actions section).

Every port can also be set to forwarding mode that allows user to forward it to
TCP/UDP port (as server or client). Port /dev/ttyS0 can also be forwarded to modem control
or modem data port-in that case no other mode can be set on that port.

Setting certain modes on /dev/ttyS0 and /dev/ttyS1 enables setting port parameters:
baud rate, data bits, parity checking and protocol. If parameter is inactive that means that user
can't control it in currently set mode.

4.2.7 TCP/IP forwarding

You can forward single port or port ranges onto certain IP address To add new rule for
single port, enter TCP/IP Forwarding tab. In Single port rules section click button New and
enter all necessary information: identifier, check Enabled field, enter external and internal

18

port, choose protocol (TCP or UDP) and enter IP address. When adding new rule or switching
tab, currently edited rule is automatically saved. You can delete it (or any other rule) by
pressing Delete button. After changes click Save Settings to save whole configuration. You can
edit port range rules in the same way in Port range rules section. You can also set IP address of
demilitarized zone in DMZ section.

4.2.8 VLAN

VLAN tab enables user to create virtual IP addresses. You can define IP, netmask and
identifier from range 0-4095. If you enable IEEE 802.1Q tagging Virtual IP becomes part of

19
