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 inuence 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 simplied 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.
