4.5 Remote Port User Interface
The Remote Port of the MM200 allows for complete control and monitor functions via an RS-485
Serial Interface.
Control and status messages are conveyed between the MM200 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.
Complete information on monitor and control software is contained in the following sections.
