Atoll Modbus RTU Gateway Starter Kit

Atoll's MODBUS-RTU starter kit has the following distinct components:

  1. Atoll Modbus Gateway (ARxxx/ATxxx Series)
  2. Atoll Configuration Board
  3. Atoll Confix

Atoll Confix

Atoll Confix is the configuration application developed by Atoll solutions to configure and manage ARxxx and ATxxx series of devices. The ATOLL CONFIX allows customers to configure the ARxxx and ATxxx series Gateways to Cloud/private Servers (Either TCP/IP, HTTP GET, and HTTP POST and HTTPS). This also helps to interface to any external MODBUS devices and input /outputs.

Atoll Configuration board
Atoll Configuration board allows customers to interface and configure Atoll Gateways from their computer. Customer can connect Atoll CONFIX board with their computer with a standard Micro USB cable. This board also provides mechanism for customers to test all features of Gateway before connecting to the assets.


  The following are the configurable features using this 

   Atoll Confix: 

  • Server endpoints like IP address/Host name, Port, URL location. 
  • Data headers 
  •  6 set of different Modbus requests 
  • External UART configurations like Baud rate, parity and stop bit. 
  •  3 Mobile numbers. 
  •  GPS parameters like Latitude, Longitude and Altitude. 
  •  4 Digital input’s, 4 Digital output’s and 4 Analog input’s 
  •  Two 4-20mA Analog Inputs
