Sony VPL-DX125 RS-232 / IP control commands

Summary

Sony VPL-EX / VPL-DX / VPL-DW / VPL-EW Series projectors. Controllable over RS-232C and Ethernet. Ethernet exposes Sony's SDCP protocol on TCP port 53484, plus PJLink class 1 and SDAP advertisement.

Events

# UNRESOLVED: source describes SDAP as projector-broadcast advertisement (no controller-to-projector), but unsolicited event triggers not detailed. Section kept for completeness.

Macros

# UNRESOLVED: source does not document multi-step command sequences explicitly

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not contain explicit safety warnings, interlock procedures, or power-on sequencing requirements

Notes

PJLink and SDCP are independent stacks — source does not state any exclusive relationship; both can be enabled (PJLink set to OFF by default per source; SDCP also OFF by default). COMMUNITY field for SDCP defaults to "SONY" (4 alphanumeric chars, case sensitive, exactly 4 chars required). SDCP checksum formula not stated in source — implementer must derive. PJLink password is configurable via web UI; default and format not stated. RS-232C packet structure documented for VPL-EX/EW only (DX/DW series excluded per source §3 heading). ERST error digit ordering per source: 6th=Fan, 5th=Lamp, 4th=Temp, 3rd=Cover, 2nd=Filter, 1st=Other.

Verification Summary

verdict: verified
checked_at: 2026-06-02T07:06:43.915Z
matched_actions: 27
action_count: 27
confidence: medium
summary: "All 27 spec actions matched literally to source commands; transport parameters (port, COMMUNITY) verified; one alternate (USB TYPE A for DX/DW) not in EX/EW spec. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "USB TYPE A"
- "RS-232 serial line parameters (baud, parity, etc.) not stated in source. SDCP set/get command field details for REQUEST payload format partially missing."
- "source states RS-232C is supported but does not give baud/data_bits/parity/stop_bits values in the refined excerpt"
- "PJLink password procedure mentioned (\"set a password from the Web setting screen\") but password format/length not specified"
- "source describes SDAP as projector-broadcast advertisement (no controller-to-projector), but unsolicited event triggers not detailed. Section kept for completeness."
- "source does not document multi-step command sequences explicitly"
- "source does not contain explicit safety warnings, interlock procedures, or power-on sequencing requirements"
- "PJLink command list truncated — source states 14 commands supported, refined excerpt enumerates 9 (POWR, POWR?, INPT, INPT?, AVMT, AVMT?, ERST?, LAMP?, INST?) plus 4 info queries (INF1?, INF2?, INFO?, CLSS?) = 13 visible. Missing 1 command. RS-232 serial parameters, SDCP REQUEST command field structure, SDCP checksum formula, PJLink password format/default, and full input source code map per model all unstated."
