Wireless RS485 Modbus RTU Gateway
AirGate is a great solution if the RS485 network requires wireless connectivity — for example, where it's not feasible to route wires over long distances or through inaccessible areas. It can be used to rapidly expand an existing RS485 network.
AirGate is a universal device, not restricted to Novus Automation products, and can be used with any RS485 device communicating via Modbus. Note that two or more AirGate devices are required to create the network.
As an extender of the Modbus RS485 network, it offers flexibility and scalability for various networks inside facilities, with long-range wireless communication reaching up to 3200 feet (1000m).
Operating through Novus's own NOVUS-Air wireless network protocol (802.15.4), AirGate-Modbus is independent from the customer's IT infrastructure.
Communication has secure data traffic, ensured by 128-bit encryption, and uses available frequency bands with less interference, providing stability and reliability in the communication link. Easy installation, configuration, and diagnostics make AirGate-Modbus an outstanding product for field commissioning.

Frequently Asked Questions
Do I need one AirGate or two?
Two or more AirGate devices are required to create the wireless network — one alone can't bridge a link.
Does this work with non-Novus RS485 devices?
Yes — AirGate is a universal device and works with any RS485 device communicating via Modbus, not just Novus products.
How far can the wireless link reach?
Up to 3200 feet (1000m) line-of-sight, using Novus's own NOVUS-Air 802.15.4 wireless protocol.
Industry Applications
- Long-Distance RS485 Links — replaces cable runs where wiring isn't feasible over distance or through obstacles.
- Network Expansion — rapidly extends an existing RS485 network without new cabling.
- Field Commissioning — easy installation and diagnostics suit fast deployment on site.
