Sony VPL-P Series Control Spec

Summary

Sony VPL-DX/DW/EX/EW series projectors are remotely controllable over RS-232C and Ethernet. The Ethernet interface supports SDCP (Simple Display Control Protocol) on port 53484 with a community-based auth scheme, SDAP broadcast for discovery, and PJLink Class 1. RS-232C uses a binary Simplified Command protocol with item-number-based set/get operations framed by A9h/9Ah start/end codes.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: null  # UNRESOLVED: baud rate not stated in source (section 3-2 truncated)

  flow_control: null  # UNRESOLVED: flow control not stated in source
addressing:
  port: 53484  # SDCP default factory port
auth:
  type: community  # SDCP uses 4-character community string, default "SONY" (case sensitive)
  notes: PJLink password can be set from Web setting screen > Setup > Advanced Menu

Traits

traits:
  - powerable     # inferred: POWR power control command present
  - routable      # inferred: INPT input switch command present
  - queryable     # inferred: multiple query commands (POWR?, INPT?, ERST?, LAMP?, INST?)

Safety

# UNRESOLVED: source mentions cooling state after power-off but does not specify

# CONTROLLER is prohibited from sending several commands at one time (RS-232C).

Notes

• Source covers RS-232C Simplified Command (binary, A9h/9Ah framing), Ethernet SDCP, SDAP, and PJLink protocols. Not all models support all inputs (e.g. S VIDEO and INPUT C absent on VPL-DX/DW models).
• SDCP Ethernet community string default "SONY" (4 chars, case sensitive). Three or fewer characters not allowed.
• SDCP version field = 02h; equipment category code = 0Ah for projectors. SDCP header ID = 4441h.
• PJLink Class 1 is supported and can be enabled/disabled from Web settings screen > Setup > Advanced Menu.
• RS-232C uses D-Sub 9 Pin cross (reverse) cable. Controller must not send multiple commands simultaneously.
• INF1/INFO/CLSS queries return "ERR4" on projector error or warning conditions.
• VPL-EX series + VPL-EW series: 15 bit PROJECTOR; VPL-EW series: 20 bit PROJECTOR (infrared remote command code width).
