AI4AVSummary
OPPO BDP-103/105 Blu-ray Disc Player RS-232 control protocol (Version 1.1, October 22, 2012). Extension of the original BDP-83 protocol; backwards compatible with BDP-83 and BDP-93/95 controllers. ASCII command set with #-prefixed 3-letter command codes terminated by CR, returning short or verbose @-prefixed responses, plus optional unsolicited status update messages. Uses a DCE-configured female 9-pin D-Sub connector with a straight-through DB9 cable (do NOT use a null-modem cable).

Macros
# UNRESOLVED: source contains illustrative example sequences (power on -> eject -> play
# -> stop -> eject -> power off) but does not declare formal named macros. No macros populated.
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlocks, or power-on sequencing
# requirements beyond the cabling note ("Do NOT use a Null-Modem type cable for PC connection"),
# which is a wiring instruction, not a runtime safety interlock.
Notes
- Protocol revision: Version 1.1, October 22, 2012. Backwards compatible with the BDP-83 and BDP-93/95 protocol; existing controllers do not require reprogramming.
- The host should wait for a response before issuing the next command. If a new command arrives before the previous one finishes, the player MAY discard the previous command.
- If no response arrives within 10 seconds, the host may consider the command lost and retransmit.
- The
#(0x23) character must never appear inside command parameters; the@(0x40) character must never appear inside response parameters. - Each command and each response is capped at 25 bytes including the start-of-frame and CR terminator.
- Verbose mode 1 echoes the command code in the response (e.g.
@PON OK ONinstead of@OK ON). Verbose modes 2 and 3 additionally emit unsolicited@U***status updates from front-panel buttons, IR remote, RS-232 commands, and playback progress. - The
SIScommand rejects values 5/6/7 on the BDP-103 withER INVALID; these audio inputs are BDP-105-only. - DCE pin assignment: pin 2 = TXD, pin 3 = RXD, pin 5 = GND. Use a straight-through cable, NOT a null-modem cable, when connecting to a PC.

Known Gaps
- "source contains illustrative example sequences (power on -> eject -> play"
- "source contains no safety warnings, interlocks, or power-on sequencing"
- "exact behaviour of FREV/FFWD/SFWD/SREV speed-level mapping in playback status query (QPL) is not stated beyond the verbose-mode FFWn/FRVn/SFWn/SRVn definitions."
- "full enumeration of QHD response values not stated — source lists only \"480P\", \"720P50\", \"1080P60\", \"AUTO\" as examples."
- "response format for #SRC (INPUT button) not stated beyond \"OK\"."
