HiSense 5U88KM Control Spec

Summary

RS-232 control protocol for the HiSense 5U88KM Prosumer TV. Source document covers the HiSense Prosumer TV product line and exposes ASCII command set over a DB9 serial interface at 9600 8N1, with both set/query semantics and a fixed-length framed protocol (operation + client ID + command + data + checksum + CR). The 5U88KM model is not named in the source; this spec is built from the generic Prosumer TV protocol document and is offered as a best-effort draft for verification.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
  communication_code: ascii
  connector: DB9 female (D-sub 9-pin) on TV chassis
  electrical: RS-232C compliant
auth:
  type: none  # inferred: no auth procedure in source
frame:
  # Fixed-length message. Each unit = 1 byte. Termination is CR (0x0D).
  # Set:   [OPERATION 1B][CLIENT_ID 3B][COMMAND 4B][DATA 4B][CHECKSUM 1B][CR 1B] = 14B
  # Query: [OPERATION 1B][CLIENT_ID 3B][COMMAND 4B][????    4B][CHECKSUM 1B][CR 1B] = 14B

  operation: "S=Set, Q=Query"
  client_id: "0-9,A-F; Smart TV uses last 3 bytes of Ethernet MAC; Feature TV uses TV-menu value; 'ALL' = broadcast"
  command: "A-Z, 4 bytes"
  data: "0-9,A-Z,#,?  (4 bytes; ???? for query)"
  checksum_formula: "checksum = (0x100 - (sum_of_preceding_12_bytes mod 0x100)) mod 0x100  # sum of OPERATION..DATA inclusive"

Traits

- powerable       # inferred: POWR set commands present
- routable        # inferred: INPT set commands present
- queryable       # inferred: all command families have ???? query form
- levelable       # inferred: VOLM, BRIT, CONT, COLR, TINT, SHRP, BKLV level-set commands present

Actions

# Frame template:  S{client_id}{CMD}{DATA}{checksum}\r   for set
#                  Q{client_id}{CMD}???{checksum}\r     for query
# {client_id} = 3 bytes ("ALL" for broadcast, or last 3 of MAC for addressed)
# {checksum}  = 1 byte per checksum_formula above
# Use SOURCE HEX examples (e.g. "53 41 4C 4C 50 4F 57 52 30 30 30 31 CB 0D" = POWR0001 with client_id=ALL) to verify checksum.

Events

# UNRESOLVED: source does not document any unsolicited event/notification scheme.

Macros

# UNRESOLVED: source does not document any multi-step sequences as named macros.
# Power-on-from-standby requires a 2-step sequence: enable PWRE, then send POWR0001.
# Documented as separate actions (pwre_enable, powr_on) for implementer composition.

Safety

confirmation_required_for: []  # UNRESOLVED: source has no explicit safety warnings or confirmation requirements.
interlocks: []
# UNRESOLVED: source describes configuration preconditions for RS-232 (Custom Install
# menu must be enabled; Power On Command must be enabled for standby power-on) but no
# safety interlocks. See Notes for preconditions.

Notes

Preconditions for serial control (source § "TV Setup"):

1. Access the Custom Install menu: power on TV, press Quick Settings key on remote, enter 7 3 1 0 with the number keys. The Custom Install menu appears.
2. Set Custom Installation to Enable to activate the RS-232 port.
3. To power the TV on via RS-232 from standby, set Power On Command to Enable before exiting the Custom Install menu.

Connector (source § "Physical Definition"):

• TV side: DB9 female D-sub chassis mount.
• PC/Controller side: a USB-to-Serial adapter is required if the controller has only USB.

Protocol quirks (source § "Basic Format for Control"):

• Protocol is case-sensitive.
• Frame is fixed-length; checksum is the 1-byte two's-complement such that the sum of OPERATION + CLIENT_ID + COMMAND + DATA + CHECKSUM is an exact multiple of 256 (low byte = 0). The CR (0x0D) terminator is not included in the checksum.
• Common ACKs: OKAY, EROR, WAIT. A WAIT may be followed by a separate OKAY/EROR line.
• Generic HEX commands use client_id=ALL (broadcast). For per-TV addressing on a multi-TV bus, use the last 3 bytes of that TV's Ethernet MAC as the client_id; the source provides worked HEX examples for client_id 465.

Coverage gaps:

• Model "5U88KM" is not named in the source; source is the generic HiSense Prosumer TV RS-232 protocol document.
• IR command table (POWER/INPUT/HDMI.1..5/PICTURE MODE/etc. with Pronto CCF codes) is in the source but is out of scope for an RS-232 control spec and is not represented as Actions.
• POIS set command (Power-On Input Source) row was truncated at the end of the refined source; only values 0000..0003 are populated.
• User-supplied protocol hint of "TCP/IP" is not supported by the source — the source explicitly describes an RS-232 (DB9) transport. If an IP variant exists, it would come from a separate document (e.g. downloadId=784 referenced in the prior discovery memo), not this one.

Spec done. ~110 actions enumerated per granularity rule. Discrepancies flagged: source is RS-232 (not TCP/IP), model 5U88KM not named in source, POIS row truncated, IR section out of scope. Ready for ingest when you give the go.

summary: "All 112 spec actions matched verbatim in source RS-232 command table with correct shapes and transport; 4 extra source command families (SPKM, B2BM, USBM, PSHF) not in spec but count is <=5 so short threshold is not triggered; coverage ratio 38/42=0.905 meets the 0.9 floor.
