Antex XM-3000 TriplePlay Multizone Satellite Receiver
RS232 Control Port Command Set
10/25/05
This document describes the commands needed to access various functions of the Antex
XM-3000 TriplePlay XM three zone satellite receiver via its rear RS232 serial port The
communications channel is RS-232 format, (transmit, receive and ground) 9600 baud, No
parity, 8 data bits, 1 stop bit. No hand shaking. Receiving equipment must be able to
accept a string of 60 characters without breaks.
Typical cable construction

2 RXD - 2 TXD
3 TXD - 3 RXD
5 GND - 5 GND
All commands supported via the RS232 port are either global or explicitly specify the
zone of the receiver to be controlled. The format of these commands is, for example,
*CUz, for “Channel Up” where “z” is the zone the controller is incrementing. Note that
the front IR receiver and hardwired IR commands also support the concept of “current
zone” commands, described in a separate document.
Each command string sent to the receiver must start with an {*}(hex 2A) and be
terminated with a carriage return {cr}(hex 0D). The sender may also optionally send a
line feed {lf}(hex 0A) after the carriage return. A line feed is not required, and if sent
will be ignored parsing of command strings sent to the receiver terminates when a
carriage return is received.
A circular buffer 256 bytes deep is used to buffer the commands received until they can
be processed. A terminating {cr} must end each command, even if multiple commands
are sent back to back. For example, to do a Channel Up followed by Select, send
CU1{cr}SL1{cr}. Any spaces (20 hex) or nulls (00 hex) sent will simply not be stored in
the buffer and will have no adverse effect. The buffer is intended to allow back to back
commands, or inputs from users in different zones at the same time. It is still possible to
overflow the buffer if, for example, a user pounds on the Channel Up button 100 times,
not waiting for the channel up action to occur after each button push.
