OPPO BDP-93EU RS232 Manual V1.0

The OPPO BDP-93EU Bluray player is fitted with a standard RS232C port for wired
remote control. The RS-232C port is configured as a DCE device using a female 9-pin
D-Sub type connector.

RS-232 Pin Configuration:

The pin out of the BDP-93EU RS-232C port is as the following:

Pin
Signal

2 3 5
TXD RXD GND

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.

Communication Settings:

Baud Rate Data Bits Parity Stop Bit Flow Control

9600 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
(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 the followings:
<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

1

<Parameters> = command-specific
<End of Command> = CR, ASCII 0x0d

Response Structure:

Upon receiving a command, the player shall try to execute the command and send back
a response. Two response formats are supported: the short response and the verbose
response. The short response is used by default. If the verbose mode (See command
reference for SVM) is set, the verbose response will be used instead.

The response starts with an “@” sign (ASCII 0x23), followed by the original command
code and a space (ASCII 0x20) if the verbose response is in use, and 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.

The illustration of the response structure is as the followings:
<Short Response> = <Start of Response><Result Code>[<sp><Parameters>]

<End of Response>

<Verbose Response> = <Start of Response><Command Code><sp><Result Code>

[<sp><Parameters>]<End of Response>
<Start of Response> = @, ASCII 0x40
<Command Code> = <byte><byte><byte>
<Result Code> = OK|ER
<sp> = space, ASCII 0x20
<Parameters> = command-specific
<End of Response> = CR, ASCII 0x0d

Status Update Messages Structure:

If the verbose mode is set to 2 or 3, the player will send status update messages
automatically. These messages are not a response to any particular command. Any
status change caused by commands from RS232, front panel buttons, IR remote control,
or playback progress may trigger status update messages.

The status update messages have the following structure:
<Update> = <Start of Update><Status Code>[<sp><Parameters>]<End of Update>

<Start of Update> = @, ASCII 0x40
<Status Code> = <byte><byte><byte>
<sp> = space, ASCII 0x20
<Parameters> = status-specific
<End of Response> = CR, ASCII 0x0d

Command Sequence:

Commands are executed in the order they are received. The host should wait for a
response from the player before sending the next command.

2

If the player receives a new command before executing the previous command, the
player may discard the previous command.

If the host does not receive a response from the player 10 seconds after the command is
issued, the host may consider the command or response lost during transmission, and
can retransmit the command.

Command List:

A. Command that maps to a remote control button

This group of commands maps directly to the infrared remote control keys. No
parameters are needed for these commands. The player handles the commands as if it
receives the same IR remote commands. For actions that require a multiple-key
sequence, such as go to a certain chapter (GOT command followed by multiple numeric
key commands and the SEL command), the player responds to each command
individually until the last command is received. At that time the player shall respond with
either OK or ER depending on the result of the action.
