This pin configuration allows connection of a personal computer to the player by a straight-through 9-pin RS-232 serial cable, and a serial
terminal (e.g. Hyper Terminal) is operated for communication. Please don’t connect the player to your personal computer through any
“Null-Modem” cable.
To understand how to create connections, please refer to the document on remote control system.

Command Structure
Each command starts with “#” (ASCII code is 0x23), followed by one 3-character command code. It ends with a line feed upon carriage
return (ASCII code is 0x0d 0x0a).
The command structure is exemplified as follows:
<Command> = <start symbol><command code><end symbol>
<Start symbol of command> = # (ASCII 0x23)
<Command code> = <byte><byte><byte>
<Parameters>=specific commands
<End symbol of command> = carriage return (ASCII 0x0d) [line feed (ASCII 0x0a)]
