GD419K2 is a high speed radio modem with over the air speed of 19200bps. It is ideal for point-to-point as well as point-to-multi-point remote control and data collection applications which makes setting up a communication link fast and easy.
With RS485 serial
interface, it offers completely transparent
communication between devices. Depending on the output power of the radio modem
and the antenna gain, the coverage range of GD419K2 can be extended up to 30 kilometers
or more in pure line-of-sight conditions.
