Features
The APart PC1000R is a professional multisource CD/USB/SD card music player, equipped with balanced
and unbalanced analog outputs, coaxial and optical digital outs and a RS232 port for use in automated
systems.
The maximum analog output level can be preset at the back to match the output level of other audio sources,
such as tuners and other media players.
The unit can be controlled by the front panel buttons, infrared remote (included), infrared remote extender
such as PIR-REC (optional) or RS232 commands. A list with the commands is included in this manual.

Communication with PC1000R via RS232 is done with simple ASCII commands. The port settings are :
38400 baudrate, 8 databits, no parity, handshake off. These parameters can not be changed.
The physical connection is made with a straight through wired 9 pin serial cable (NO null modem cable !)
Maximum wire length depends on cable quality and inuence caused by external interference.
Pin 2 : TX data : data transmission output.
Pin 3 : RX data : data transmission input.
Pin 5 : GND : ground connection.
Other pins are not used.
Serial commands used in PC1000R have been simplied and consist basically of a command such as
PLAY, STOP, ...commands are not case sensitive.
Some commands require an attribute, such as TRACK #, where # stands for a numeric value, in this case
the track number. The unit needs no carriage return <CR> at the end of the instruction.
From here we assume that you are familiar with RS232 communication protocols and hardware. If not,
please read the user manual of your control device rst. In case you are experiencing a problem with serial
communication, start at the basics, connect a computer with a working serial port, use the right serial cable,
use a simple terminal program, make communication settings and start from there.
Please note that most commands sent from the infrared remote control will also be shown on the serial
port. This is the easiest way to nd out whether your serial communication settings are correct. Unknown
characters in your terminal communication program usually indicate that the baudrate is incorrect.
Below is a table with the list of commands recognized by PC1000R and some examples of the replies sent
by the PC1000R.

Important notice: always allow the unit to acclimatize during at least one hour. E.g when the unit has been
transported in cold weather conditions, the electronics and optical devices inside the unit might condensate,
causing malfunction or even permanent damage to the unit !
Please note that the unit may respond slowly when you change the input source. This depends on the size
and number of les present on the media.

• Do not spill water or other liquids into or on the unit.
• Make sure power outlets conform to the power requirements listed on the back of the unit.
• Do not use the unit if the electrical power cord is frayed or broken.
• Always operate the unit with the AC ground wire connected to the electrical system ground.
• Have gain controls on ampliers turned down during power-up to prevent speaker damage
if there are high signal levels at the inputs.
• Do not connect the inputs / outputs of ampliers or consoles to any other voltage source,
such as a battery, mains source, or power supply, regardless of whether the amplier
or console is turned on or off.
• Power down & disconnect units from mains voltage before making connections.
• Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
• Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages.
