Features
The APart SDQ5Pir powered loudspeaker set is a versatile and very compact, easy to use, plug and play
sound system. It consists of an amplied loudspeaker with a 5.25” woofer, a high frequency unit and a
second linkable passive loudspeaker, powered by the second amplier built into the active speaker. The
speakers are magnetically shielded.
The speakers can be remote controlled via the included infrared remote control, RS232 serial port or an
optional wall control panel with or without local input. The auto power off function switches off the power
amplier when no audio signal is present for a certain time. This time window can be adjusted using RS232
commands.
Further benets are: presettable maximum level, dual inputs: unbalanced on minijack and balanced on
euroblock + additional input via optional wall control unit. All inputs can be gain adjusted, used individually or
mixed together (except optional wall control panel local input source : this input can not be mixed with the A
or B or A+B inputs).
The automatic power on function will power up the speaker automatically from the standby position when
a sufciently strong audio signal is present. The threshold can be adjusted via RS232 control to suit your
needs.

Communication with SDQ5Pir via RS232 is done with simple ASCII Commands and Replies. The port
settings are 19200 Baudrate, 8 databits, no parity and 1 stop bit. The physical connection is as described
below:
Standard 9 pin serial cable, wired straight through (no null modem cable !!!). Maximum wire length
depends on cable quality and inuence from external interference.
Pin 2: TX data: data transmission output
Pin 3: RX data: data reception input
Pin 5: GND: ground
Other pins are not used.
NOTE: when the unit is in standby mode, it may not respond to the rst command sent to the unit, unless
you send the command “SET STANDBY OFF”. If you want to send any other command while the unit is in
standby mode, it will wake up from standby and reply “STANDBY OFF”. After that, resend the command
and it will be executed.
An instruction has at least a command and an attribute. In many cases, there are extra values needed,
like a source lettre or a value. From here we assume that you are familiar with RS232 communication
protocols and connections. If not, please read the user manual of your control device rst.
Instructions always have to be ended with <CR>, carriage return. Line feed <LF> characters will always be
omitted, however SDQ5Pir can use (and echo) <LF> after a <CR>. Instructions are not case sensitive!
The 4 possible commands are: SET, GET, INC and DEC. With the INC and DEC command, a “step value”
can be specied. See the table below for details (in the value column).
Operating Settings:
SDQLVL is the volume level of the speaker system. Possible values are: OFF (mute) or any value between
-63 (lowest) and 0 (highest volume level). E.g. you want to set the volume to -20: SET SDQLVL -20 <CR>
The unit will reply: SDQLVL -20
MAXLVL is the maximum allowed volume level. E.g. if you don’t want anyone to set the SDQ level higher
than -10, set the MAXLVL parameter to -10. All volume related commands will ALWAYS be related to the
MAXLVL setting. E.g. if the MAXLVL is -10 and you enter the command SET SDQLVL -20, the SDQ5Pir
will set the level relative to the MAXLVL, which was -10.
Please note that the absolute maximum number of volume steps is limited to 64 steps. 1 volume step
corresponds to 1.25 dB.
The MAXLVL parameter is therefore considered as the master volume. If you want to mute the speaker,
you can set the MAXLVL parameter to OFF.
BALANCE sets the balance between left and right channel. Possible values vary between -31 and 31.
Equalizer:
EQBASS sets the level of the bass.
EQTREB sets the level of the treble.
The value must be between -14 and 14 in steps of 2. If a different value is used (e.g. “5”), it will be
changed to the closest match.

Conguration Settings:
SELECT is input source selection, a possible command could look like this: “Set select AB<CR>”. In this
case, both inputs A and B will be mixed together by the SDQ5Pir unit. Possible values are A, B, AB or
WI. WI is the local input of the optional waal control
IPGAIN is input gain. Each source input has its own gain setting so the source (A, B or WI) needs to
be specied. The value can be between 0 and 3 in steps of 1. If an invalid value is used or no source
is specied, “ERROR: Value Invalid!<CR>” will be replied. Otherwise, the reply will be “Command
Executed!<CR>”
A command to set the input gain of source A to 1 looks like this: SET IPGAIN A 1<CR>
AUPTRG: auto power trigger level. Range from 0 to 30. Higher values will increase the trigger level.
RS-232 Settings:
All RS-232 settings are binary values, they can be ON or OFF.
If ECHO is on, all received characters are echoed back. This can be handy when programs like
hyperterminal are used.
LF is Line Feed. Line Feed is an ASCII character (0x0A) which is sometimes used to let the cursor jump
to the next line. SDQ5Pir always omits the line feed character. However, when LF is on, there will be put
<LF> character behind each <CR> character. This is both the case for echoing as for messages sent by
SDQ5Pir. Please take a look to following example: in both cases, the user sends the following string: “get
sdqlvl<CR>”.
With ECHO on and LF off, this will be returned by SDQ5Pir :
“get sdqlvl<CR>” (command)
“SDQLVL -16<CR>” (reply)
In case both ECHO and LF are on, it will be like this:
“get sdqlvl<CR><LF>”
“SDQLVL -16<CR><LF>”
BS is Back Space. This is also an ASCII character. In case BS and ECHO is on, SDQ5Pir will reply
<BS><SP><BS> each time when a <BS> is received. <SP> is the space character. This setting is only
intended to have a “nice” text when used with programs like Hyperterminal.
VALFB means value feedback. Possible values are on or off. When value feedback in on, the SDQ5Pir
will reply its setting after a value has been changed, such as SDQLVL.
Version information:
HWVRSN will return the hardware version number: GET HWVRSN<CR>
SWVRSN will return the hardware version number: GET SWVRSN<CR>
Control settings:
BACKCT: set the controls at the back of the unit on or off. NOTE: when set to off, you can NOT operate
the unit from the back panel controls !!!
WALLCT: set the control of the optional wall control panel on or off.
IRRMCT: set the control by infrared remote on or off.
AUTOPW: set the time for the auto power off function. When no audio signals are detected, the speaker
will go to standby mode after the AUTOPW time has elapsed. When set to 0, the AUTOPW function in
not active. Values between 0 and 30 can be specied. 0 = inactive, 1 = auto power off after 1 minute
etc...Default value is 15 minutes.

Restore Factory Settings:
The factory defaults are shown in the RS232 commands table. In order to restore the factory default
settings, enter the following command: SET RESTORE ON<CR>
This function can also be executed without using RS232 commands. In that case, power off the speaker.
While pushing BASS + and - buttons on the rear panel simultaneously, power up the speaker with the
power switch. The multifunction led will be orange. Release the BASS + and - buttons one second after
powering up. All factory defaults will be restored.
Standby:
The SDQ5Pir can be switched to Standby mode with the IR remote control or with the “SET STANDBY
ON<CR>” instruction. Leaving Standby mode can also be done with IR remote controller or the “SET
STANDBY OFF<CR>” instruction. If an RS232 instruction is sent when the amplier is in Standby mode
or during power on, and the amplier is not ready, it will answer “STANDBY ON”. Please wait until the
speaker is operational (green led at the back is lit) and resend the instruction.
