RS232 communication
Communication with PC1000RMKII via RS232 is done with simple
ASCII commands. The port settings are: 38400 baudrate, 8
databits, no parity, handshake off. These parameters cannot 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 influence caused by external
interference.
Serial commands used in PC1000RMKII have been simplified 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 first. 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
Pin 2: TX data : data transmission output.
Pin 3: RX data : data transmission input.
Pin 5: GND : ground
Other pins are not used.

to find out whether your serial communication settings are correct.
Unknown characters in your terminal communication program
usually indicate that the baudrate is incorrect.
