Antex SRX-3 TriplePlay Multizone Satellite Receiver

RS232 Control Port Command Set

4/22/2004

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

HOST CONTROLLER		SRX-3 Male DB9
PIN#		PIN#
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. 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)

pppp = (password) valid values are 0000 – 9999 (must have leading zeros)

Global Command Group

*PR Power Command

*PR0{cr}

Turns the unit off, stopping music in all 3 zones

*PR1{cr}

Turns the unit on, providing music in authorized zones.

*PR{cr}

Queries the current powered state of the receiver

Returned: *PR0{cr} if unit is off

*PR1{cr} if unit is on

Zone Specific Commands

*CHz Direct Tune Channel Number - Query or Set

This command sets or queries the current channel number for each music zone. The number following the *CH is the zone (ie CH1 queries or sets the channel on zone 1). *CHz sent without a parameter will query the current channel number for the requested zone. Valid parameters for z are 1,2,3. valid parameter for ccc are 001 – 223.

*CHz{cr}

Queries the current channel number on zone z

Returned: *CHz,ccc,catagory,channel name,artist name,song title{cr}

Example: *CH1,007,Pop,Totally 70’s,Earth, Wind and Fire,Can’t Hide Love{cr}

If *CHz,ccc{cr} is sent, the receiver will change to that channel for the requested zone and return the above string syntax.

*CDz Channel Down (decrement)

This command decrements the channel for the zone specified. For instance, *CD1 will decrement the audio channel for Zone 1. If the z specifier is not sent it will decrement the currently active zone. In this way, channels may be changed by a remote controller that does not keep track of the current channel the receiver is set to. Note that this command does not tune to the decremented channel it only returns the following information.

Returned: *CDz,ccc,catagory,channel name,artist name,song title{cr}

Example: *CD1,007,Pop,Totally 70’s,Earth, Wind and Fire,Can’t Hide Love{cr}

The above string will be returned after the selected channel remains stable for one second. Nothing will be returned with rapid decrements.

Use the *SLz command to tune to the channel. The *SLz command must be received within 4 seconds of the last *CDz command to force a direct tune.

*CUz Channel Up (increment)

This command increments the channel for the zone specified. For instance, *CU1 will increment the audio channel for Zone 1. If the z specifier is not sent it will increment the currently active zone. In this way, channels may be changed by a remote controller that does not keep track of the current channel the receiver is set to. Note that this command does not tune to the decremented channel it only returns the following information.

Returned: *CUz,ccc,catagory,channel name,artist name,song title{cr}

Example: *CU1,007,Pop,Totally 70’s,Earth, Wind and Fire,Can’t Hide Love{cr}

The above string will be returned after the selected channel remains stable for one second. Nothing will be returned with rapid decrements.

Use the *SLz command to tune to the channel. The *SLz command must be received within 4 seconds of the last *CUz command to force a direct tune.

*CGDz Category Down (decrement)

This command decrements the category for the zone specified. For instance, CGD1 will decrement the audio category for Zone 1. If the z specifier is not sent it will decrement the currently active zone. In this way, category may be changed by a remote controller that does not keep track of the current category the receiver is set to. Note that the current category type can be determined using the QZz command.

Returned: *CGDz,ccc,catagory,channel name,artist name,song title{cr}

Example: *CGD1,007,Pop,Totally 70’s,Earth, Wind and Fire,Can’t Hide Love{cr}

The above string will be returned after the selected catagory remains stable for one second. Nothing will be returned with rapid decrements.

The Channel number returned is the first channel in the category found by decrementing.

*CGUz Category Up (increment)

This command increments the category for the zone specified. For instance, CGU1 will increment the audio category for Zone 1. If the z specifier is not sent it will increment the currently active zone. In this way, category may be changed by a remote controller that does not keep track of the current category the receiver is set to. Note that the current category type can be determined using the QZz command.

If the z specifier is not sent it will increment the currently active zone.

Returned: *CGUz,ccc,catagory,channel name,artist name,song title{cr}

Example: *CGU1,007,Pop,Totally 70’s,Earth, Wind and Fire,Can’t Hide Love{cr}

The above string will be returned after the selected catagory remains stable for one second. Nothing will be returned with rapid increments.

The Channel number returned is the first channel in the category found by incrementing.

*SIDz Serial Identification Number Query

This command is used to query the 10 digit identification number (ESN) of each music zone. The number following the ID is the zone (ie *SID1 queries zone 1).

Returned: *SIDz,nnnnnnnnnn{cr }

*QZz Query Zone Information

This command dumps all pertinent information about the specified zone including Channel Name, Category Name, Artist Name, Song or Program Title. This information may be used for display on a remote control panel.

QZz,nnn,ccc{cr} where z is zone number, nnn is number of ascending channels to get data from, starting with ccc channel

Returned: QZz,ccc,(channel name),(category name),(artist name),(song title),ccc+1,(channel name),(cataegory name),(artist name),(song title),ccc+2,…..{cr}

*SKz Skip Channel

This command removes the specified channel number from the universe of channels allowed when using Up/Down commands. Note that unlike parental blocked channels skipped channels may still be tuned to directly by their channel number. The number following the SK is the zone (ie SK1 skips the channel on zone 1). Valid parameters for z are 1,2,3.

If SKz,ccc{cr} is sent, the receiver will skip channel ccc for the requested zone z.

*USz Unskip Channel

This command adds the specified channel number to the universe of channels allowed when using Up/Down commands. Parental blocked channels cannot be added. The number following the *US is the zone (ie *US1 unskips the specified channel on zone 1). Valid parameters for z are 1,2,3.

If *USz,ccc{cr} is sent, the receiver will unskip channel ccc for the requested zone x.

*LKz Lock Channel

This command locks out the specified channel number from the universe of channels allowed when using Up/Down commands or direct tune commands. This command requires a 4 digit password that is previously programmed via the front panel or the *PW command. The number following the *LK is the zone (ie *LK1 locks the channel on zone 1). Valid parameters for z are 1,2,3. pppp is the 4 digit password.

If *LKz,ccc,pppp{cr} is sent, the receiver will lock channel ccc for the requested zone z if the password pppp is correct.

Returned *LKz,ccc,1{cr} if lock is successful

*LKz,ccc,0{cr} if password is incorrect

*ULz Unlock Channel

This command unlocks the specified channel number from the universe of channels allowed when using Up/Down commands or direct tune commands. This command requires a 4 digit password that is previously programmed via the front panel or the *PW command. The number following the *UL is the zone (ie *UL1 unlocks the channel on zone 1). Valid parameters for z are 1,2,3. pppp is the 4 digit password.

If *ULz,ccc,pppp{cr} is sent, the receiver will unlock channel ccc for the requested zone z if the password pppp is correct.

Returned *ULz,ccc,1{cr} if unlock is successful

*ULz,ccc,0{cr} if password is incorrect

*PW Password command

This command will change the current password.

If *PW,pppp,wwww,wwww{cr} is sent, where pppp is the old 4 digit password and wwww is the new 4 digit password, the password will be change to wwww. The new password is sent twice for verification.

Returned *PW1{cr} New password accepted

*PW0{cr} failed (old password is incorrect)

*SLz Select command

This command is the equivalent of the select button on the front panel. It can be sent after a *CD, *CU, *CGD and *CGU command to cause the receiver to direct tune to the last channel sent by these commands. This command must be sent within 4 seconds of the previous listed commands or it will be ignored.
