RS-232
RS-232 is via the USB port.
Use the USB to RS-232 adaptor included. Other USB to RS-232 adaptors may not work.
The pin out is:
Pin 2
3 5
Signal TXD RXD GND
This pin configuration allows a PC running a serial terminal program (such as Hyper Terminal) to
communicate with the soundbar using a straight-through DB9 9-pin RS-232 serial cable.
Do NOT use a “Null-Modem” type cable for PC connection.
Communication Settings:
Baud Rate Data Bits Parity Stop Bit Flow Control
19200 8 None 1 None
Command Structure:
Each command starts with a
# sign (ASCII 0x23) followed by a 3-character command code.
If there are any parameters for the command, the parameters are given in text format, separated by a
space (ASCII 0x20) from the command code.
The # character must never appear in the parameters.
A carriage return (ASCII 0x0d) indicates the end of the command.
A line feed (ASCII 0x0a) can optionally follow the carriage return and will be ignored.
Each command generally may not exceed 20 bytes including the start of command and end of
command bytes.
The illustration of the command structure is as follows:
<Command> = <Start of Command><Command Code>[<sp><Parameters>]<End of Command>
<Start of Command> = #, ASCII 0x23
<Command Code> = <byte><byte><byte>
<sp> = space, ASCII 0x20
<Parameters> = command-specific
<End of Command> = CR, ASCII 0x0d LF, ASCII 0x0a
