SEA GSM-BGS5-E2N User Manual

GSM-BGS5-E2N

If you are using WIN10 and you will use only control via AT commands, do not
download the driver, WIN10 will install its own driver automatically.

1. Introduction

Modem in an industrial metal aluminum case which
is suitable for installation into a control cabinet.
Modem has two communication ports (RS232 and
USB) with adjustable watchdog. The modem is equipped with a GSM module Gemalto
(Cinterion) BGS5 rel.2. Thanks to standard RS232 and USB interface, the 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.
The modem has JAVA OPEN PLATFORM in which you can write your own program, for
example a program for downloading and sending data from connected technology.
For RS232 and USB parameter setting see the chapter 7.4.
Modem can be powered directly from the USB connector.

7. Hardware

7.1 Power supply and it’s indication

Supply voltage is connected to terminals PWR and must be
in the range of 7-33 VDC. 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. As the power consumption from USB is higher than 100mA, it is
sometimes needed to reserve the current or use powered USB hub.

The modem can be powered directly from the USB connector, even using RS232.
If the modem uses power supply from USB cable, the communication is posible only via

USB (not vir RS232. For communication via RS232 you must use external power supply
(GSM-PWR12).

LED PWR is located on the bottom-right side of PWR connector, LED RS232 is located

Insert the nano SIM card into the holder (cut corner first,
contacts up - towards the inscription SIM). The correct insertion
is indicated by mechanical click noise. Push gently and release
to remove the SIM card.

Above the SIM card holder is located the LED which indicates

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 Communication ports (RS232 and micro-USB)

To communicate with the modem (AT commands) is designed interface RS232 and USB.
The device includes a female connector RS232 and micro-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 for RS232 is 115200bps,
8 data bits, no parity, 1 stop bit. For changing the rate, see the Chapter „RS232
Setting“. Baud rate for USB is not needed to set.

You will see two COM ports in WIN Control panel. For sending AT commands you must
use the port, which you find in Device Manager „Modems“ (Parameters/Modem). Other
port is determined for JAVA application´s development.

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

BGS5

9.1 RS232

The device contains a built-in watchdog which checks whether the modem answers (if
there are changes in the internal line RxD between GSM module and connected
apliance). 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.

Time, which is still not considered an error of modem is configured using commands via
serial interface RS232. USB port is not possible to use for Watchdog setting!

Factory default is 115200bps, 8 data bits, no parity, 1 stop bit.

Notes:

 Before each command must be a time of 1 second when there are no

characters sent!

 Characters '-' and '+' in the following examples are sent. '-' … mean Data

are sent to the device, '+' means data are sent by the device.

 '<#0D>' is a placeholder for ENTER (13d, 0x0D).

11. Frequently Asked Question

11.1 Command for Watchdog setting does not
respond

- GSMWDG 52<#0D>

+ <nothing>
The problem is in the assignment of the time "52". It is required to enter the exactly 6-

HEX digits. The correct command is this:

- GSMWDG 000052<#0D>

+ WDG: OK 000052 D2251D v1.0

Command SET

Watchdog setting

- GSMWDG 112233<#0D>

+ WDG: OK 112233 D2251D v1.0
The parameter ‘112233’ means seconds (coded in HEX). See the table for command

ECHO. Exactly 6 HEX numbers has to be entered, including leading zeroes.
Value ‘000000’ disables Watchdog function = modem is never restarted by Watchdog.
Example: Disable Watchdog

- GSMWDG 000000<#0D>
