The following multi-drop override IDs are device-type specific, with the exception of "BROADCAST".
These are summarized in Table 4-6 with ID values expressed in decimal notation:
Multi-drop override ID 01 can be used interchangeably to broadcast a message to a DMD-3000/4000
modem, a DMD-4500/5000, a DMD15 modem, or a DVB3030. Radyne ComStream Corporation
recommends that the multi-drop override IDs be issued only during system configuration as a bus
test tool by experienced programmers, and that they not be included in run-time software. It is also
advantageous to consider the use of multiple bus systems where warranted by a moderate to large
equipment complement.
Therefore, if a DMD15 Modulator is queried for its equipment type identifier, it will return a "20" and
DMD15 Demodulator will return a "21". A DMD15 Modem will also return an "22". A DVB3030
Video Modulator will return a “23.”
4.4.2.6 Software Compatibility
The COMMSPEC, operating in conjunction within the RLLP shell, provides for full forward and
backward software compatibility independent of the software version in use. New features are
appended to the end of the DATA field without OPCODE changes. Older software simply discards
the data as extraneous information without functional impairment for backward compatibility.
If new device-resident or M&C software receives a message related to an old software
version, new information and processes are not damaged or affected by the omission of data.
