Document version Issue date
2.11 09.20.2013
Prepared by V.N. Golovin Approved by P.A. Kosolapov
1.3. Safety rules
Restrictions on the use of the device near other electronic devices:
Turn the modem off in hospitals or when located near medical equipment such as pacemakers, hearing
aids and so on. Interference for medical equipment may occur
Turn the terminal off when on an airplane. Take measures to avoid accidental turning on
Turn the modem off in the vicinity of gas stations, chemical plants, and places where demolition work is
conducted. Interference for technical devices may occur
At a close range, the modem may produce interference for television sets and radio transmitters
Maintenance requirements:
Protect the modem against external hazards (high temperatures, caustic chemicals, dust, water and so
on)
Keep the modem safe from blows, falls, and strong vibrations
Do not attempt to take apart or modify the modem on your own. Such actions will void your warranty
Note: Make sure you follow the operation manual for this device. Improper use of the device will disqualify
your warranty.

2.5. Interfaces
2.5.1. Plug-in terminal connector
This connector is used for communication with a controlling device, interface RS485. The AT-commands
are used to control the modem operation (see the module description).
Factory settings: Speed: 115200 bps, Data Bit: 8, Parity: None, Stop Bit: 1.
Fig. 2.5.1. Plug-in terminal connector
Table 2.5.1: Using terminal connector pins
Pins Signal Purpose
1 +Vin “+” modem power supply
2 -Vin “-” modem power supply
3 SHLD “Shield” of RS485 interface
4 “B” “d-“ of RS485 interface;
inverse differential I/O
5 “A” “d+“ of RS485 interface;
direct differential I/O
Interface lines are protected by self-healing fuses anda
circuit of impulse noise suppression, as well as
overvoltage protection
6 +5V Output ”+5V” (RS485), 100mA (to power external devices)*
*For instance, it might be used to power RS485 interface of heat and electricity counters, etc.
Notes: RS485 interface is half duplex. It needs to be considered in case of data transfer. When echo is
enabled, data is sent to the modem will return. This can lead to collision. In this case we recommend to
disable echo (AT-command ate0).

2.6. Power connector
TJ6-6P6C for RJ12 power connector is used to power the device. Also displayed on Fig. 2.5.2 are two keys
to the “ground” and two ADC channels.

Contact Signal Purpose
1 + 12V The positive pole of DC supply voltage. Fused circuit and overvoltage
protection (when input voltage of over 30V is applied) and reverse polarity
2 Output of the “dry
contact” type to the
ground
Controlled by GPIO4 module output. When “logical 1” exits from the module
output, the “dry contact” output shortens to the “ground”
3 ADC2 Analog to digital converter. Parameters of the input circuit include input
resistance of 180kOhms and input voltage divider by 10. Connected to the
ADC2 pin of the GSM module
4 ADC1 Analog to digital converter. Parameters of the input circuit include input
resistance of 180kOhms and input voltage divider by 10. Connected to the
ADC1 pin of the GSM module
5 Output of the “dry
contact” type to the
ground
Controlled by GPIO5 module pin. When “logical 1” exits from the module
output, the “dry contact” output shortens to the “ground”
6 GND Ground
Output of the “dry contact” type goes through a 10 Ohm resistor to the collector of the BC817 transistor.
The output of the GSM module goes to the transistor base. The emitter of the transistor is connected to the
“ground”. The maximum current of the “dry contact” output is 80mA.
