Wireless Modem connected to an Adcon Telemetry Gateway

The A440 Wireless Modem is an essential component of an A850 Base Station, which is requesting data from UHF RTUs. The A440 is connected to the A850 Telemetry Gateway via a custom RS-485 cable, which not only provides a communication link, but also power to the A440.

To communicate with Adcon's UHF RTUs the A440 employs the same 500mW radio modem as is also being used in our long range units A731, A732 and A733. By default the A440 is meant to be mounted in an elevated location, for example on the roof of the building where the A850 is installed. With proper installation distances of up to 20km can be achieved. Please make sure that installation is done with proper grounding of both components, A850 and A440. Consult an expert technician to make sure that all guidelines and recommendations for lightning protection are observed!

A440 is available in four different frequency bands, each covering 10MHz. Please make sure to order the correct frequency range according to your local regulations.
