The ARF868 is a new generation of radio modems that can be used to transmit bidirectional signals.Wireless data in half duplex up to 4 km. These 25 mW products are available in two versions:
• ARF868 MR (medium range) with a maximum range of 4 km.
• ARF868 LP (Long power) with a maximum range of 1 km.
Running on 863-870 MHz, these modems are certified and can be used without a license.
In order to guarantee quick and easy implementation, the ARF868s are equipped with a single DB9 connector incorporating an automatic type (RS232 / RS485) and a bit rate (Autobaud) recognition. An optional serial-to-USB converter is also available.
To enable their use for applications over very long distances or in harsh environment environments, the ARF868s offer a repeater function *. They also present a "Legacy" mode ensuring "air" compatibility with all
radio modems of the "X" 3-PRO range. The small, yet lightweight and rugged housing is equipped with a DIN rail mounting so that it can be immediately integrated into an industrial environment. For harsh environments requiring increased protection of modems, IP53 and IP67 options are available.
