HiSense 5U63KUA RS-232 / IP control commands

Summary

RS-232 / discrete IR control protocol for HiSense Prosumer TV (5U63KUA). This spec captures the serial control surface (set/query ASCII commands over a fixed-length framed protocol on a DB9 connector at 9600 8N1). The document also documents a large discrete IR code table, summarised in Notes but not enumerated as serial actions.

Source explicitly states: "RS-232C Compliant", "Baud Rate 9600bps (UART), Data Length 8bits, Parity Bit None, Stop Bit 1bit, Flow Control None, Communication Code ASCII".

NOTE: the request prompt labelled this as "TCP/IP", but the source contains no IP/network transport — the MAC address field is only used to populate the 3-byte client ID for multi-TV serial addressing. Protocol is serial RS-232 only.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
  communication_code: ASCII
  connector: DB9 female chassis mount  # from source: "standard DB9 D-sub connector. The jack type on the TV is a female chassis mount connector"
auth:
  type: none  # inferred: no auth procedure in source

Frame format (from source, verbatim)

Command (PC/Control System → TV), fixed length 14 bytes:

Field	Size	Notes
OPERATION	1 byte	`S` for Set, `Q` for Query
CLIENT ID	3 bytes	`0-9,A-F`; Smart TV = last 3 bytes of Ethernet MAC; `ALL` = broadcast
COMMAND	4 bytes	`A-Z`, see Commands table
DATA	4 bytes	`0-9,A-Z,#,?`
CHECKSUM	1 byte	8-bit; whole string including CHECKSUM byte sums to 0x00
TERMINATION	1 byte	`0x0D` (CR)

Acknowledgement (TV → Controller):

[CLIENT ID 3B] : [ACK 4B] [DATA 4B] [CHECKSUM 1B] [0x0D]

ACK is most commonly OKAY, EROR, or WAIT. The protocol is case sensitive.

Traits

- powerable       # inferred from POWR / PWRE commands
- routable        # inferred from INPT input select commands
- queryable       # inferred from many Q???? query commands
- levelable       # inferred from BRIT, CONT, COLR, TINT, SHRP, VOLM, BKLV level commands

Actions

# Generic (broadcast) HEX form used for all commands below: SALL + COMMAND(4B) + DATA(4B) + CHECKSUM(1B) + 0x0D
# For broadcast to "ALL" client ID the ASCII form is "SALL<CMD><DATA><cs>\r" (13 visible chars + CR).
# For per-TV addressing, replace "ALL" with last 3 hex bytes of the TV's MAC address.
# Checksum byte is computed so the 8-bit sum of the entire string (including the checksum byte) equals 0x00.
# Source states: "The protocol is case sensitive."

Events

# UNRESOLVED: source describes no unsolicited event/notification frames. Acknowledgement is a
# per-command response; no asynchronous event channel is documented.

Macros

# Source example 1 in the protocol section describes a two-step "Power on" sequence:
#   1. S5FAPOWR232  ->  5FA:OKAY####  (enables RS-232 Power On)
#   2. S5FAPOWRON##  ->  5FA:WAIT####  ->  5FA:OKAY####
# This is the documented "Power On" sequence when the TV is in standby and Remote Power-On
# has not been pre-enabled. Implementations may need to issue PWRE0001 once before POWR0001
# will take effect.
- id: power_on_with_remote_enable
  label: Power On (with remote-power-on enable)
  steps:
    - action: pwre_enable
    - action: power_on
  notes: From source Example 1. PWRE0001 must be issued first; without it, POWR0001 from standby is rejected.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not document safety warnings, interlocks, or power-on sequencing
# requirements beyond the RS-232 enable step needed for POWR to function. None inferred.

Notes

Protocol classification: this is RS-232 serial only. The "Client ID" 3-byte field uses the last 3 bytes of the TV's Ethernet MAC address, which the source describes as a way to address a specific TV in a multi-TV RS-232 bus. There is no IP/TCP transport in the source; "TCP/IP" in the request prompt appears to refer to the MAC-address field, not the transport itself.
Frame size: 14 bytes fixed (1+3+4+4+1+1). The protocol is case sensitive (source note).
Termination: 0x0D (CR) on every frame; do not append LF.
Checksum: 8-bit checksum appended so that the sum of all bytes in the frame (including the checksum byte) modulo 256 equals 0x00. Implementation must compute, not hard-code.
Multi-TV wiring: source labels section "Connecting to multiple TVs" but the wiring details are described as image content and were not extractable from the refined text. UNRESOLVED.
Custom Install menu must be enabled before the RS-232 port is active. Source procedure: Quick Settings → "7 3 1 0" on remote → scroll to "Custom Installation" → set to "Enable". For remote power-on to work from standby, also set "Power On Command" to "Enable" in the same menu.
Discrete IR codes: source contains a separate 60+ entry table of Pronto-format IR codes (POWER, POWER ON, POWER OFF, INPUT, TV TUNER1, HDMI.1..5, VGA, USB, PICTURE MODE, SOUND MODE, ASPECT RATIO variants, CHANNEL LIST, FAV CHANNEL, SLEEP, TV MENU, HOME, TOOLS, digit 0..9, dash, PREVIOUS CHANNEL, arrows, ENTER, SELECT OK, RETURN, EXIT, INFO, VOLUME ±, CHANNEL ±, PIP toggles, PIP INPUT, PIP SWAP, PIP POSITION, PIP SIZE, Guide, Freeze). These are documented for IR control only and are NOT enumerated in this serial spec.
POIS table truncation: the source's POIS (Power On Input Source) table is truncated at value 3 (Component) in the refined document. Possible additional rows (HDMI1..4, VGA, etc.) not captured.
Title page: source document title is "RS-232/IR Protocol for Hisense® Prosumer TV". The "Models" field on the title page is empty in the refined source. The "5U63KUA" model identifier in this spec is taken from the request prompt, not from a model field within the source.
Revision history: source revision notes document V1.0..V3.6; revision history does not affect protocol surface.
