1. Introduction
Modem in industrial metal aluminum case which is
suitable for installation into a control cabinet.
Modem has two serial ports (RS232 and USB) with
adjustable watchdog. The modem is equipped with a
GSM module Cinterion EGS5. Modem is suitable for
fast implementation in devices that require remote
communication. It also includes the monitoring of
communication with the master device (watchdog), both via RS232 serial port as well
as the USB.

7. Hardware
7.1 Power supply and it’s indication
Supply voltage is connected to terminals PWR and
must be in the range of 8-30 VDC or 12-30 VAC. The
polarity is therefore irrelevant. The device is
protected against overvoltage and has a built in
refundable SMD fuse. If the external fuse is needed,
use 1.25 A fuse at VCC line. GSM-EGS5-TU can be
powered directly from the USB connector.

7.3 Antenna
The antenna is connected via SMA connector. The device is fitted with SMA female.
The connected antenna must have SMA male. The impedance is 50 Ω.
7.4 Connectors RS232 and mini-USB
To communicate with the modem is designed interface RS232 and USB. The device
includes a female connector RS232 and mini-USB. The modem can be controlled using
both interfaces, for setting up of the watchdog function is possible to use only RS232
interface.
Factory default baud rate for communication with the modem is 115200 bps, 8 data
bits, no parity, 1 stop bit.
7.5 DIN rail mounting
If you need to place the device into the switchboard on DIN rail, screw the plastic
holder GSM-75-DIN drilled hole in the side of the modem.

9. Watchdog setting
The device contains a built-in watchdog which checks whether the modem (line RXD
on RS232 or USB). If it is no change on the line for specified time period, the modem
is considered broken and is cut off from the power supply for 15 seconds. After that
the modem and monitoring process starts again.
