Document Name: USER MANUAL for GW IoTG1M/G8M  

 

INTRODUCTION 

 
GW  IoT  is  used  for  remote  monitoring  of  modbus  devices  via  cellular  network.  It  acts  as  a 
modbus  master  to  multiple  modbus  slave  field  devices  at  a  single  location  and  provides 
reliable  data  connection  to  a  web  based  application  server.  Unit  is  designed  to  be  used  in 
industrial panels and operates on 18V-36V DC, 1A power supply. 
 

FEATURES 

 

  Modbus RTU Master interface for field devices 

  Connects by itself to external web server. 

  Self-embedded with integral PPP, TCP/IP and HTTP protocol stack. 

  RTC support (battery backed). 

  Robust design with DIN rail mounting and wall mounting enclosure. 

  Industrial Power Terminal block for 18V ~ 36V DC operation. 

  One console port (Mini USB) for local configuration. 

 

8 MB memory for data storage if Network drops

 

 

MODELS 

 

  GW IoTG1M (2G Model) 

  GW IoTG8M (4G Model) 

 
Cloud server protocol can be HTTP GET, HTTP POST, MQTT and FTP. 
 

INSERTING/REMOVING THE SIM CARD- 

 
To  insert  or  remove  the  SIM  Card,  it  is  necessary  to  press  the  yellow  SIM  holder  ejector 
button  with  Sharp  edged  object  like  a  pen  or  a  needle.  When  this  is  done  the  SIM  holder 
comes out a little, then pull it out and insert or remove the SIM Card. It is very important that 
the SIM is placed in the right direction for proper working.   
 

OPERATION 

 

      GW IoT is first configured with APN name of service provider of the SIM through USB console 

port.  At  power  on,  GW  IoT  connects  to  internet  using  cellular  network.  After  successful 
internet  connection,  it  reads  the  configuration  CSV  file  which  is  stored  on  FTP  server.  The 
FTP  path  for  the  CSV  file  is  configured  through  USB  port  console.  Gateway  reads  file  from 
server using HTTP GET request. So FTP server folder should be enabled to read files using 
HTTP GET protocol. This can be tested by putting the path in any standard web browser like 
IE, Chrome or Firefox.
