Depili dVision IVision 30 20 Series Control Spec

Summary

Binary RS-232 control protocol for a Depili projector (dVision IVision 30 20 Series family). All commands are 32-byte packets (7-byte header + 11-byte payload + 14 bytes padding) with a 16-bit CRC. The protocol exposes SET, GET, INCREMENT/DECREMENT, and EXECUTE operations covering source selection, picture controls, power, scaling, orientation, gamma, color temperature, and projector telemetry.

Transport

protocols:
  - serial
serial:
  baud_rate: 19200
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

# All traits inferred from command set in source.
- powerable     # inferred from Power on/off commands
- routable      # inferred from source-select commands (VGA1, VGA2, DVI, Component, S-video, Composite)
- queryable     # inferred from GET commands (Lamp Ignition, Thermal Monitor, Source, Power, etc.)
- levelable     # inferred from increment/decrement commands (Brightness, Contrast, Volume, AudioTreble, AudioBass, Hue, etc.)

Actions

# All commands are 32-byte packets: 5-byte constant prefix (BE EF 03 19 00) +
# 2-byte CRC + 1-byte op-type + 2-byte op-code (lo,hi) + 2-byte validation
# (0x00 0x00) + 4-byte target (0x00 0x00 0x00 0x00) + 2-byte value (lo,hi) +
# 14 zero-byte padding. The 16-bit CRC is computed over the entire packet
# with the CRC bytes initialized to zero (see Appendix B for CRC-16 algorithm).
# PAK (0x1E) acknowledgement prepends the echoed command for a 33-byte response.
#
# Op-type codes:
#   0x01 = OPERATION_SET
#   0x02 = OPERATION_GET
#   0x03 = OPERATION_INCREMENT
#   0x04 = OPERATION_DECREMENT
#   0x05 = OPERATION_EXECUTE

# Note: Source Get, Power Get, Orientation Get, Brightness Get, Contrast Get,
# Light/Unit On Time Gets, and Software Version Get return a WORD in bytes
# 17-18 of the response payload, but the source does not enumerate the
# value-to-state mapping for these (only their existence as commands).
# UNRESOLVED: response value maps for source/power/orientation/brightness/
# contrast/light-on-time/unit-on-time/software-version queries.

Variables

# Source documents only INCREMENT/DECREMENT operations for the picture
# parameters (no absolute SET for Brightness/Contrast/Volume/etc.) and a
# single SET for color temperature presets. Continuous parameter ranges,
# units, and limits are not enumerated in the source.
# UNRESOLVED: per-parameter min/max/step ranges and units for Brightness,
# Contrast, Hue, Sharpness, Color Saturation, Phase, Frequency, Volume,
# AudioTreble, AudioBass, Horizontal/Vertical Position, Horizontal/Vertical
# Keystone, and per-channel (R/G/B) Brightness/Contrast/Temp adjustments.

Events

# The source describes PAK (0x1E) acknowledgements echoed after every
# operation, but does not document unsolicited notifications (e.g. lamp
# fault, thermal shutdown) that the device may send.
# UNRESOLVED: no unsolicited event packet formats documented in source.

Macros

# UNRESOLVED: source does not document multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock
# procedures, or power-on sequencing requirements.

Notes

All packets are 32 bytes: 5-byte constant prefix BE EF 03 19 00, then a 16-bit CRC, then a 1-byte op-type (0x01=SET, 0x02=GET, 0x03=INCREMENT, 0x04=DECREMENT, 0x05=EXECUTE), then a 2-byte op-code (little-endian), then 2 bytes validation, 4 bytes target, 2 bytes value, and 14 bytes of zero padding to reach 32. The CRC is a 16-bit lookup-table CRC (CRC-16/ARC variant per Appendix B) computed over the entire 32-byte packet with the CRC bytes initialized to zero. Every response prepends PAK (0x1E) to the echoed command for a 33-byte response; for INCREMENT/DECREMENT/EXECUTE the echoed packet's byte 11 carries a validation code of 0x01 and the CRC is recomputed accordingly. Sub-Brightness and Sub-Contrast adjustments apply only to analog RGB (VGA) inputs. R/G/B color-temperature increment/decrement commands require "Custom color temp" to be selected first (via one of the Color Temp SET commands) or they will not take effect.
