Communication ports are used for the following purposes:
•
10/100 Mb/s Ethernet port – this port is not used
•
mini USB 2.0 port - the module configuration port;
•
169 MHz RF modem - RF communication with subordinate elements (terminal devices);
•
GSM/LTE modem - communication with the central application.
The module is enclosed in a plastic casing adapted for mounting on a DIN-rail. The box has a standard
”
circuit
breaker” profile and width of four standard DIN-modules. The module needs an external power supply 12V to 24V
DC. For connecting of the power supply there is a screw terminal with marked voltage polarity.
The module RF transceiver is equipped with the
coaxial connector
of SMA (Female) type designated for inter-
connection of an external antenna (directly or via coaxial cable). The GSM modem is equipped in the same way.
Both connectors are connected to the module front panel and are marked as ”ANT 169 MHz” and ”ANT GSM”.
The module is equipped with a SIM card holder for using with a SIM card of the ”Mini-SIM” format (2FF) with
dimensions of 25 x 15 x 0.76 mm. The SIM holder is located on the module front panel, to the left of the LCD
display.
On the right side of the front panel there is the 40x20 mm LCD display and control buttons. These elements are
used for displaying the module basic parameters.
