Summary

Control spec for the Sharp/NEC AS60U PX39ML projector over RS-232C serial and wired/wireless LAN (TCP). Binary command protocol using hex byte frames with a trailing additive checksum (low-order byte). Covers power, input switching, mute, picture/volume/aspect adjustment, lens control and memory, status queries, and eco/PIP/edge-blending settings.

Transport

# Source documents BOTH RS-232C serial (PC CONTROL port, D-SUB 9P) and LAN (TCP port 7142).
# Command frames are identical byte sequences across both transports.
protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source: selectable baud rates
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source lists "Full duplex" communication mode and wires RTS/CTS pins but does not state a flow-control setting
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands."
auth:
  type: none  # inferred: no auth/login procedure in source

Traits

traits:
  - powerable       # inferred: 015 POWER ON / 016 POWER OFF present
  - queryable       # inferred: many *REQUEST commands returning values present
  - levelable       # inferred: picture/volume/gain/lens adjustment commands present
  - routable        # inferred: 018 INPUT SW CHANGE present

Actions

# All 54 command-bearing entries from the source command list (section 2) are
# enumerated, each carrying its verbatim hex payload. Parameterized commands
# show the variable DATA bytes. CKS = checksum (low-order byte of the sum of all
# preceding bytes). ID1 = control ID set on projector; ID2 = model code.

# edge_blending_mode_set, audio_select_set, volume_adjust, picture_adjust,
# aspect_adjust, other_adjust, lens_profile_set, lens_memory_option_set.
# UNRESOLVED: numeric ranges for eco mode / aspect / input terminal value maps deferred to Appendix not present in source.

Events

# Source documents request/response only; no unsolicited notification frames described.
# UNRESOLVED: no push/event mechanism stated in source

Macros

# UNRESOLVED: no multi-step sequences explicitly described in source

Safety

confirmation_required_for: []
interlocks: []
# Source notes: POWER ON / POWER OFF block all other commands during the transition
# (including cooling time). This is a behavioral constraint, not an interlock sequence.
# No explicit safety warnings, interlock procedures, or power-on sequencing
# requirements are documented in the source text.
# UNRESOLVED: no safety-critical interlock procedures present in source

Notes

  • Command frame format: lead byte (00h-03h request / 20h-23h success response / A0h-A3h error response), command byte, ID1 (control ID), ID2 (model code), LEN, DATA bytes, CKS. Example checksum: 20h 81h 01h 60h 01h 00h → sum = 103h → CKS = 03h.
  • ID1 uses the projector's configured control ID; ID2 varies by model and is not stated for the AS60U PX39ML in this source.
  • Many value maps (input terminal values, aspect values, eco mode values, sub input values, base model types) are deferred by the source to an Appendix ("Supplementary Information by Command") that is not included in this refined document.
  • Serial cable is a cross cable wired to the PC CONTROL D-SUB 9P port; LAN uses RJ-45 (10/100 Mbps auto-sensing, IEEE 802.3 / 802.3u). Wireless LAN requires a separate wireless LAN unit (see its operation manual).

Spec done. 54 actions, all hex payloads verbatim. Serial + TCP both (port 7142 stated). Baud list kept verbatim. Marked UNRESOLVED: ID2 model code, Appendix value maps, flow_control, firmware.

```

## Known Gaps

```yaml
- "model-specific input terminal value map and several per-command value maps are referenced to an \"Appendix / Supplementary Information by Command\" that is not present in the source text. flow_control value not explicitly stated. firmware version compatibility not stated."
- "source lists \"Full duplex\" communication mode and wires RTS/CTS pins but does not state a flow-control setting"
- "detailed feedback schema for each query response not fully enumerated"
- "numeric ranges for eco mode / aspect / input terminal value maps deferred to Appendix not present in source."
- "no push/event mechanism stated in source"
- "no multi-step sequences explicitly described in source"
- "no safety-critical interlock procedures present in source"
- "ID2 model code for AS60U PX39ML not stated. Appendix value maps (input terminal, aspect, eco mode, sub input, base model type) not present in source. flow_control not stated. firmware version compatibility not stated. protocol/binary spec revision (BDT140013 Rev 7.1) noted but per-model applicability unconfirmed."
- "ID2 model code, Appendix value maps, flow_control, firmware."
```
