4.4 Remote Port User Interface
The Remote Port of the DM240XR allows for complete control and monitor functions via an RS-
485 Serial Interface.
Control and status messages are conveyed between the DM240XR and the subsidiary modems,
and the host computer using packetized message blocks in accordance with a proprietary
communications specification. This communication is handled by the Radyne Link Level
Protocol (RLLP), which serves as a protocol ‘wrapper’ for the M&C data.
