Summary

This document is a serial (RS-232) HEX-command control spec transcribed from a Hisense B2B guide. It covers E SERIES digital signage, M SERIES 24/7 digital signage, and WR SERIES interactive touch displays. It is unrelated to the requested PL2NE model.

Transport

# Source is RS-232 serial only. No TCP/IP, HTTP, UDP, or OSC in source.
# (Requested protocol "TCP/IP" is NOT supported by this source - see Summary.)
protocols:
  - serial
serial:
  baud_rate: 9600  # M-SERIES and WR-SERIES use 9600; E-SERIES uses 115200
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
# E-SERIES serial override: baud_rate 115200 (all other params identical).
# Pinouts differ per series (E: RJ45 pins 4/5/7; M: pins 3/5/8; WR: pins 2/3/5).
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable   # inferred: Power On / Power Off commands present (all 3 series)
  - routable    # inferred: input-select commands present (all 3 series)
  - queryable   # inferred: query commands returning state present (all 3 series)
  - levelable   # inferred: Set Volume / Set Brightness present

Actions

# Coverage: every distinct command row in the source, across E/M/WR series.
# Each row is a separate action (per granularity rule).
# All payloads are HEX bytes, verbatim from source. xx = screen ID (01-FF, or 00
# for broadcast); yy = XOR check bit; vv = volume 00-64; ww = mode/value as noted.
# Commands are grouped by source series. E-SERIES requires baud 115200; M/WR use 9600.

Feedbacks

# M-SERIES Query Status response frame (most complete feedback in source):
- id: m_status_frame
  type: object
  format: "AB AB 00 0C 28 00 00 xx aa bb cc dd ee ff yy CD CD"
  fields:
    - {name: aa, meaning: "current volume level"}
    - {name: "bb cc", meaning: "selected input (05 02=DVI, 05 03=DisplayPort, 05 04=HDMI, 08 01=VGA)"}
    - {name: dd, meaning: "power state (00=on, FF=off)"}
    - {name: ee, meaning: "mute state (01=muted, 00=unmuted)"}
    - {name: ff, meaning: "signal presence (00=absent, 01=present)"}

# Per-command ACK/echo frames documented (verbatim prefixes):
- id: m_ack_prefix
  type: raw
  format: "BB CC / AB AB ... CD CD"  # request/response wrappers for M & WR series

- id: e_query_response_power
  type: enum
  values: ["01=Off", "02=On"]
  notes: "E-SERIES Query Power State return byte zz"

- id: e_query_response_input
  type: enum
  values: ["0D=HDMI1", "06=HDMI2", "0B=OPS", "15=CMS", "17=PDF", "16=Media", "0C=USB", "14=Home"]

# UNRESOLVED: full feedback formats for E-series queries beyond the return-byte
# descriptions are not fully specified in the source.

Variables

# Discrete settable parameters captured as actions (Set Volume, Set Brightness,
# Set Mains Application Mode, Set Date, Set Time). No additional variables.

Events

# No unsolicited notifications documented. All responses are query-driven.

Macros

# No multi-step sequences documented in source.

Safety

confirmation_required_for: []
interlocks: []
# Source notes Power Off command exists but states no interlock/confirmation
# procedure. Uart Wake On function must be On for E-series Power On to work.
# UNRESOLVED: no explicit safety warnings, power-on sequencing, or interlock
# procedures stated in source.

Notes

  • All Hisense RS-232 commands are HEX codes, not ASCII.
  • XOR check bit (yy / xx / zz depending on series) must be computed per target screen ID; value differs per ID. Source links https://onlinehextools.com/xor-hex-numbers.
  • Screen ID 00 = broadcast to all daisy-chained panels in a video wall (E-series).
  • Pinouts differ per series:
    • E-SERIES RJ45: pin 4=GND, 5=RX, 7=TX (DB-9F: 5,2,3).
    • M-SERIES RJ45: pin 3=GND, 5=RX, 8=TX.
    • WR-SERIES RJ45: pin 2=RX, 3=TX, 5=GND.
  • Baud differs per series: E=115200, M=9600, WR=9600 (all 8N1, no flow control).

**TL;DR**: Source mismatch. Output faithful E/M/WR RS-232 signage spec + glaring UNRESOLVED. Not PL2NE, not TCP/IP. Operator pick: confirm model / use community MQTT (port 36669) / keep `no_docs`. Caught 1 source doc-bug in E-series Power Off example too.

matched_actions: 68

summary: "All 68 spec actions matched their exact hex command sequences in source; transport serial/baud/parity verified across E/M/WR series. (5 unresolved item(s) noted in Known Gaps.)"
```

## Known Gaps

```yaml
- "CRITICAL SOURCE MISMATCH."
- "full feedback formats for E-series queries beyond the return-byte"
- "no explicit safety warnings, power-on sequencing, or interlock"
- "CRITICAL — see Summary. Source is E/M/WR RS-232 signage guide,"
- "E-series Power Off example in source (A6 01 00 00 00 05 01 B0 00 74 67)"
```
