    The RCI-SER-RF2 is a serial-to-radio interface. It allows PC's or PLC's to communicate directly with one or more RCI-XXX-RF2's. The standard MODBUS ASCII protocol used in the RCI-XXX-RF2 series allows for easy integration with existing software packages on both PC's and PLC's.

    The host controller connected to the RCI-SER-RF2 controls the communication by sending out queries to each remote unit. The Remote unit then replies with an acknowledgment if the data was received correctly. The license-free spread-spectrum radio technology allows small systems to be set up with very little effort and at a low cost. The technology ensures high communication reliability even in RF-intensive environments.

    All units are sold with a 1/4 wave omnidirectional whip antenna. Other antennas, such as directional Yagi or Patch antennas, are sold separately.
