    to provide wireless links between serial and Ethernet devices the modems excel in utilities, process control and manufacturing.

    The RM-240 can connect to a range of devices such as PLC’s, HMI’s, DCS, data acquisition, video and industrial PC’s. Each modem features an Ethernet port (10/100 BaseT) as well as two serial ports (RS-232 and RS-485) and onboard I/O for local and remote link status.

    Suitable for long and short range applications, the RM-240 has a sight range of 1km with suitable antenna. Distance covered can range from 1 to 10km depending on the antennas and repeater function.

    A high RF output and superior receiver sensitivity give good penetration for reliable data transfer in congested industrial environments.
