Sharp/NEC Xp V801U B Control Spec

Summary

Projector. Binary hex protocol over RS-232C serial and TCP/IP LAN (port 7142). Source: "Projector Control Command Reference Manual" BDT140013 Rev 7.1. 53 enumerated commands covering power, input switching, mutes, picture/volume/aspect/lens adjust, shutter, lens memory, eco mode, edge blending, PIP/PbP, status requests.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # all five stated in source
  data_bits: 8

Traits

- powerable      # inferred: 015 POWER ON / 016 POWER OFF
- queryable      # inferred: 009, 037 family, 078 family, 305 family, 097 family requests
- levelable      # inferred: 030-1 picture, 030-2 volume, 030-15 gain adjust
- routable       # inferred: 018 INPUT SW CHANGE

Actions

# Each command payload verbatim from source. Responses prefixed per source:
#   02h cmd → 22h ack / A2h err
#   03h cmd → 23h ack / A3h err
#   00h cmd → 20h ack / A0h err
#   01h cmd → 21h ack / A1h err
# Checksum (CKS) = low byte of sum of all preceding bytes.

Events

# UNRESOLVED: no unsolicited notifications documented in source. All responses are command-elicited.

Macros

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

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON (015): no other command accepted while power-on in progress."
  - "POWER OFF (016): no other command accepted during power-off including cooling time."
  - "078-6 / 009 bit: interlock switch open (DATA09 Bit1) reported as error status."
  - "009 bit: cover error (DATA01 Bit0), mirror cover error (DATA03 Bit5) reported in error status."
# UNRESOLVED: source contains no explicit power-on sequencing procedure beyond per-command interlocks above.

Notes

Binary protocol. All commands framed hex bytes. Format: {cmd_hi}h {cmd_low}h {00h} {00h} {LEN} {DATA...} {CKS} where cmd_hi selects command class (00h info req, 01h control, 02h action, 03h set/query-with-data). CKS = low byte of sum of all preceding bytes. Example from source: 20h 81h 01h 60h 01h 00h → sum 103h → CKS 03h.

Two ID bytes (<ID1> control ID, <ID2> model code) appear in responses only, not in commands. ID1 set on projector; ID2 model-dependent. Both must be read or known before parsing responses — command bytes do not include them.

Lens drive (053 LENS CONTROL): send 7Fh/81h to start continuous drive, then 00h to stop.

Usage times returned in seconds, updated at 1-minute intervals. Convert /3600 for hours.

Edge blending, eco mode, aspect, input terminal, base model type, sub input enums all referenced to an appendix "Supplementary Information by Command" that is NOT in this refined source. Implementor must obtain full manual.

Spec done. 53 actions, all hex payloads verbatim. Both serial + tcp transport. Flow control, ID1/ID2 values, appendix enums marked UNRESOLVED — not fabricated.

summary: "All 53 spec actions verified against source. Every hex command literal found verbatim in BDT140013 Rev 7.1 manual. Transport parameters (baud, port, data bits, parity, stop bits) all verified. Complete command coverage; no extra source commands. (14 unresolved item(s) noted in Known Gaps.)"
```

## Known Gaps

```yaml
- "model code (ID2) value not stated for this model — varies by model, must be read from device"
- "control ID (ID1) default not stated"
- "appendix \"Supplementary Information by Command\" (input terminal enums, aspect values, base model types, eco mode values, sub input values) not in source — several DATA fields reference it"
- "RTS/CTS pins wired in pin assignment, but flow control mode not stated in source"
- "enum values in source appendix, not in refined source"
- "no unsolicited notifications documented in source. All responses are command-elicited."
- "no multi-step sequences described in source."
- "source contains no explicit power-on sequencing procedure beyond per-command interlocks above."
- "appendix \"Supplementary Information by Command\" missing — affects INPUT SW CHANGE, ASPECT ADJUST, ECO MODE, BASE MODEL TYPE, PIP SUB INPUT, AUDIO SELECT enums"
- "ID1 (control ID) default and ID2 (model code) for Xp V801U B not stated"
- "flow_control mode (RTS/CTS hardware handshake) not stated despite pins being wired"
- "firmware version compatibility not stated"
- "full key code list (050 REMOTE KEY CODE) — source lists 26 keys; others may exist"
- "response timing / inter-command delay not specified"
```
