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.

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.
