The ARR600 Wireless I/O Gateway facilitates wireless monitoring and control of field devices via a cellular network. It offers industrial-quality connectivity for IEC 60870 and Modbus protocols, with built-in digital and analog I/O. The device integrates communication capabilities and connects seamlessly with SCADA systems. It supports protocol conversion, allowing older IEC60870-101 devices to connect to modern TCP/IP systems and Modbus RTU to Modbus TCP. The ARR600 acts as a TCP/IP router, enabling integration of serial and Ethernet field devices into supervisory control systems and optimizing communication costs through public cellular networks.

Troubleshooting and error codes

Problem	Suggested solution
Wireless WAN does not work.	Check mobile WAN settings, SIM card and signal level.
OpenVPN does not work.	For more information, see the OpenVPN server in Wireless Gateway/Controller technical note.
Serial ports do not work.	For more information, see serial port chapter notes. Verify DIP switch configuration if RS-422 or 485 modes are being used.
Access to web user interface does not work.	Web user interface uses HTTPS for secure web access and it must be specified on the web browser address field like in this example: https://10.10.10.10.
Access to the Internet with a laptop connected to the device does not work.	Test the wireless connection: 1. Configure wireless connection and verify if it is connected to the network. 2. Connect a laptop to Ethernet LAN. 3. Check that S-NAT rule on the firewall is set as Action is "Masquerade" and Destination Interface is "Mobile WAN". 4. Check that Use DNS Proxy is set to "Yes" in the Services/Common screen. 5. Configure network settings on laptop to use the device's Ethernet LAN address as gateway and DNS server. With these settings, the Internet should be accessible on the laptop.
