Sharp/NEC Pn E329 Control Spec

Summary

Control spec for the Sharp/NEC Pn E329 projector, derived from the Sharp/NEC Projector Control Command Reference Manual (BDT140013 Revision 7.1). The device supports two transports: an RS-232C serial connection (D-SUB 9P PC CONTROL port) and a TCP/IP LAN connection (wired RJ-45 or optional wireless LAN unit) using TCP port 7142. The protocol is binary, frame-based with a leading 20h/02h/03h/01h/00h marker, model/control IDs (ID1/ID2), a data-length byte (LEN), variable data, and a trailing checksum byte (CKS).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # one of 4800/9600/19200/38400/115200 - source lists all five, no default singled out
  baud_rate_options: [4800, 9600, 19200, 38400, 115200]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source states "Full duplex" communication mode; flow_control wire use (RTS/CTS) per pinout but not configured as hw flow control
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON (015) / POWER OFF (016) commands present
  - routable     # inferred: INPUT SW CHANGE (018) command present
  - queryable    # inferred: numerous status/info request commands present
  - levelable    # inferred: VOLUME ADJUST (030-2) / PICTURE ADJUST (030-1) present

Actions

# Binary frame protocol. Each command shown as the literal payload bytes
# from the source (hex, space-separated). <ID1> = control ID, <ID2> = model
# code, <CKS> = checksum (low byte of sum of all preceding bytes).
# Parameterized commands show <DATA..> placeholders verbatim as the source
# documents them.

Variables

# Settable parameters surfaced as discrete actions above (volume, picture
# gains, lamp/light adjust, eco mode, projector name, lens position, edge
# blending, PIP/PbP). No additional settable continuous variables beyond
# those actions are described as standalone variables in the source.
# UNRESOLVED: source does not enumerate explicit min/max/default numeric
# ranges for most settables outside the GAIN PARAMETER REQUEST 3 response.

Events

# Source describes no unsolicited / push notifications. All data is returned
# only in response to a request command.
# UNRESOLVED: no event/notification mechanism documented in source.

Macros

# UNRESOLVED: source documents no multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON (015): while power-on is in progress, no other command can be accepted."
  - "POWER OFF (016): while power-off (including cooling time) is in progress, no other command can be accepted."
  - "Several commands return error 02h 0Dh ('command cannot be accepted because the power is off') - commands requiring power-on state will be rejected in standby."
# UNRESOLVED: source contains no explicit safety warnings, interlock
# procedures, or power-on sequencing requirements beyond the command-level
# interlock notes above. Voltage / current / power specs are not in this
# document (command reference only).

Notes

• Source is the generic Sharp/NEC Projector Control Command Reference Manual (document code BDT140013, Revision 7.1). It is not Pn E329-specific; command availability per model is governed by each command's Appendix entry ("Supplementary Information by Command"), which is not included in this refined source excerpt.
• Binary frame structure: [Marker] [CMD] <ID1> <ID2> [LEN] [DATA...] <CKS>. Markers: 00h/01h/02h/03h = request, 20h/21h/22h/23h = success response, A0h/A1h/A2h/A3h = error response (high bit set).
• Checksum (CKS) = low-order byte (8 bits) of the sum of all preceding bytes in the frame. Worked example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
• ID1 = projector control ID (set on device); ID2 = model code (varies by model).
• Serial cable is a cross (null-modem) cable on D-SUB 9P; pinout in source §1.1.
• Lamp/filter usage times are returned in seconds, updated at one-minute intervals. Lamp remaining life (%) can be negative if the replacement deadline is exceeded.
• Two-lamp projector models only: lamp 2 selectors (DATA01=01h) are valid.
• For commands referencing "Supplementary Information by Command" (input terminal values, aspect values, eco mode values, base model types, sub-input values), the value enumerations live in the source Appendix which was not part of the refined excerpt — those param descriptions are marked accordingly.

Spec done. 53 actions, one per source row, all payloads verbatim. Dual transport (serial + tcp:7142), binary w/ checksum. Traits powerable/routable/queryable/levelable inferred. Several UNRESOLVED markers — biggest gap: source is generic projector manual, Pn E329 model applicability + ID2 model code not stated.

## Known Gaps

```yaml
- "the source document is a generic Sharp/NEC Projector Control Command Reference Manual and does not name the Pn E329 explicitly; model-to-command applicability and any Pn E329-specific command subset are not stated."
- "firmware version compatibility not stated in source."
- "default baud rate not singled out (five rates listed); the device selects one per software configuration."
- "authentication / login procedure not described anywhere in source."
- "source does not enumerate explicit min/max/default numeric"
- "no event/notification mechanism documented in source."
- "source documents no multi-step macro sequences."
- "source contains no explicit safety warnings, interlock"
- "exact model code (ID2) for Pn E329 not stated in source."
- "which of the 53 commands are supported on Pn E329 specifically (vs. the generic projector family) not stated — requires the per-command Appendix or the device itself."
- "default baud rate — source lists 4800/9600/19200/38400/115200 as software-configurable, no default."
- "voltage/current/power specifications — not present in this command reference document."
- "firmware version compatibility — not stated."
- "protocol version number — not stated (document revision 7.1 is the manual revision, not a wire-protocol version)."
