AOR AR-7030 Computer Remote Control Protocol Manual

AR-7030 Computer remote control protocol.
Information for firmware releases 1.1A,  1.2A,  1.4A  and  1.4B
1) Remote control overview.
The AR-7303 receiver allows remote control of all of its functions by means of a direct memory access
system.
A controlling computer can read and modify the internal memory maps of the receiver to set required param-
eters and then call for the receiver’s control program to process the new settings.
Commands to the receiver are byte structured in binary format, so it is...

5) Variations between A and B types and firmware revisions.
Type A firmware supports only basic receiver functions, type B extends operations and includes support for
the Notch / Noise Blanker option. The whole of the type A memory map is retained in type B, but more
memory and operations are added for the extended functions of type B.
In the following information, circled note numbers are included to indicate where items are specific to one
type or
revision of the firmware:-
ŒApplicable to type B...

Front panel spin-wheels logged but not actioned.
Display update (frequency & S-meter) continues.
Level 2 As level 1, but display update suspended. In revisions before 1.4
squelch operation is inhibited, which results in no audio output
after a mode change. In revision 1.4 squelch operation continues
and mode changing is as expected.
Level 3 Remote operation exclusively.
Lock level 1 is recommended during any multi-byte reads or writes of the receiver’s memory to prevent data
contention between internal...
