Active loudspeaker set
• The Apart SDQ5PIR powered loudspeaker set is a versatile and very
compact, easy to use, plug and play sound system. It consists of an
amplified loudspeaker with a 5.25” woofer, a high frequency unit
and a second linkable passive loudspeaker, powered by the second
amplifier 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 amplifier when no audio signal is present for a certain
time. This time window can be adjusted using RS232 commands.
• Further benefits are: adjustable maximum level, multiple inputs:
unbalanced on mini-jack 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 cannot be mixed with the A or B
or A+B inputs).
• The automatic power on function will power up the speaker
automatically when a sufficiently high input signal is present at one
of the selected inputs. The threshold (AUPTRG) can be adjusted via
RS232 control to suit your needs.
• Active 2 way bass-reflex speaker system
• Ideal for monitor, Audio-Video applications, multimedia applications
• Powerfull 5.25” woofer and 1” tweeter
• Mounting brackets, IR remote control and power cord included
• 2 x 30 watts dynamic output power.
• Enhanced bass response by DTB reflex tuning
• Multifunction led indicator: standby (orange), on (green), overload
(red), off (led not lit)

RS232 communication
Communication with SDQ5PIR via RS232 is done with simple ASCII
commands and replies. The port settings are 19200 Baudrate, 8 data
bits, 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 influence
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
first command sent to the unit, unless you send the command “SET
STANDBY OFF<CR>”. 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<CR>”. 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 name/character 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 first.
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 specified. See the table
below for details (in the value column).

Instruction manualSDQ5PIR

Operating settings:
SDQLVL is the volume level of the speaker system. Possible values
are: OFF (mute = -64) 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<CR>”
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<CR>”, 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.

Active loudspeaker set
Configuration 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 wall control
IPGAIN is input gain. Each source input has its own gain setting
so the source (A, B or WI) needs to be specified. The value can be
between 0 and 3 in steps of 1. One gain step corresponds to 3.75
dB. If an invalid value is used or no source is specified, “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.
RS232 settings:
All RS232 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>”.

Instruction manualSDQ5PIR
11
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.
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 sleep function. When no audio
signals are detected, the speaker will go to sleep mode after the
AUTOPW time has elapsed. When set to 0, the AUTOPW function
in not active. Values between 0 and 30 can be specified. 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 two seconds after powering up.
All factory defaults will be restored.
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 amplifier is in Standby mode or during power on,
and the amplifier is not ready, it will answer “STANDBY ON<CR>”.
Please wait until the speaker is operational (green led at the back is
lit) and resend the instruction.
When the SDQ5PIR is in standby mode, the AUPTRG function will
not be able to wake up the speaker.
In standby mode, the SDQ5PIR can only be activated by a “SET
STANDBY OFF<CR>” command, or by cycling the power switch on
the unit.
