Lexicon Blu Ray Disc Player BD-30 User Manual

80

The Lexicon BD-30 Blu-ray Disc Player can be ordered with an 

RS-232 option for wired remote control. The RS-232C port is 

configured as a DCE device using a female 9-pin D-Sub type 

connector.

The pin out of the BD-30 RS-232C port is as follows:

This pin configuration allows a PC running a serial terminal 

program (such as Hyper Terminal) to communicate with the player 

using a straight-through DB9 9-pin RS-232 serial cable. Do NOT 

use a “Null-Modem” type cable for PC connection. For connection 

to a remote control system, please refer to the documentation that 

comes with the remote control system.

The RS-232 control port of the Lexicon BD-30 uses the following 

communications settings:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bit: 1
Flow Control: None

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 

(ASCII 0x23) must never appear in the parameters. A carriage 

return (ASCII 0x0d) indicates the end of the command. Each 

command must not exceed 25 bytes including the start of 

command and end of command bytes.
The illustration of the command structure is as follows:
<Command> = <Start of Command><CommandCode> 

 

[<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

Upon receiving a command, the player shall try to execute the 

command and send back a response. The response starts with 

an “@” sign (ASCII 0x23), followed by a result code, either “OK” 

or “ER”. If there are any parameters or additional message, the 

parameters or message is given in text format, separated by a 

space (ASCII 0x20) from the result code. The @ character (ASCII 

0x40) must never appear in the parameters or message. A carriage 

return (ASCII 0x0d) indicates the end of response. Each response 

must not exceed 25 bytes including the start of response and the 

end of response bytes.
