This document describes the commands needed to access various functions of the Antex SRX-3
TriplePlay
Sirius three zone satellite receiver via its rear RS232 serial port
The communications channel is RS
-232
format, (transmit, receive and ground) 19,200 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
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. If you are using a Crestron Module and the unit is displaying TTA properly,
but you have no control over the Antex unit, please try sending a Line Feed. If you are experiencing difficulties
controlling the SRX
-3, please turn ON the Line Feed option.
Each response string sent will start with an {*} and terminate with a {
cr
}.
Commas {,} are used to delimit
separate fields in long strings. In addition the following nomenclature is used.
z = (zone number) valid values are 1,2,3
ccc
=
(channel number) valid values are 001
–
223 (must have leading zeros)
= (password) valid values are 0000 –
9999 (must have leading zeros)
