3.1 Front panel
3.2 Back panel
3.3 External connections
3.3.1 GSM/UMTS/LTE antenna connector
SMA antenna connector placed on front panel is used to connect external
GSM/UMTS/LTE. It must be connected to establish a connection with GSM/UMTS/LTE
network. In good circumstances (good coverage, level of received signal is high) use antenna
which is included in package. When signal strength is poor please use outdoor
directional/omnidirectional or indoor antenna.
Note: If antenna is not connected, connection with GSM/UMTS/LTE network will be
impossible.
3.3.2 Modem serial port, either full RS232/RS485
Serial RS232/RS485 (RJ-45 connector marked as “RS232/485”) is placed on front
panel of router. Serial connector pinout is described in a tables below.
3.3.3 LAN connector
Second RJ-45 connector (marked as “LAN”) is placed next to serial connector and is
used for communication with PC or laptop through Ethernet interface. WWW configuration is
available in the web browser (default IP address is 192.168.1.234). You can change the default
address in “Local network” tab.
3.3.4 Power supply connector
Please use power adapter which is included in package. It ensures “clean” power
supply input and avoids short transients on power supply lines originating from inductive
load switching. Power supply range of RBMTX-Lite router is 9-30V.
3.3.5 SIM card holders
One SIM card holder is placed in front panel of RBMTX-Lite and the second one is
located inside the device. To insert SIM card into the extractable holder push yellow button
and take SIM drawer out as show in the picture and place SIM card. To operate the module in
a GSM network, it is necessary to insert at least one active SIM card.
3.4 Product sticker
A production sticker includes the following information:
● Product serial number
● CE marking
● 15-digit bar code
● model signature (RBMTX-Lite)
