the GSM modem iRZ MC52i-485GI.
1.2. Service data
Document version Issue date
2.11 08.29.2013
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. General Information
2.1. Purpose
iRZ MC52i-485GI is an industrial GSM modem for receiving and transmitting data, text messages and
faxes. It is perfectly suited both for providing mobile access to the Internet and for industrial applications
including telemetry, wireless data collection from sensors, remote monitoring, control, and signaling.
The modem is equipped with a watchdog timer, which allows for an unconditional reboot of the equipment
after a specified period of time. The modem is controlled by standard AT-commands and also possesses its
own range of control commands. The device is equipped with LEDs to monitor connection status and signal for
emergency.
This modem is mainly used for remote queries on CSD channel; and it is configured accordingly when
manufactured. Please see p. 2.5.1 for more details.

2.5. Interfaces
2.5.1. 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: 9600 bps, Data Bit: 8, Parity: None, Stop Bit: 1.
This modem is mainly used for remote queries on CSD channel; and it is configured accordingly when
manufactured:
ats0=1 (automatic answer)
at&c1 (set DCD line mode)
at&d0 (ignore status of the DTR line)
at+cbst=71,0,1 (select bearer service type)
ate0 (echo mode off)
Please see the external look of the connector on Figure 2.5.1:

Table 2.5.1: Using terminal connector pins
Clamps 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 and a
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).
2.5.2. Power connector
The connector is used to power the device.

Table 2.5.2: Using connector power pins
Pin 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.

2.6. Modem status display
LED is used to indicate the connection status. This function can be controlling by a corresponding
AT-command (AT^SSYNC=1 — LED mode on; AT^SSYNC=0 — LED mode off). By default, AT^SSYNC=1.
