HiSense 5U8K Control Spec

Summary

The HiSense 5U8K is a prosumer-class television controllable via an RS-232 serial interface on a DB9 connector. The source document (V3.6, 17-Apr-2017, "RS-232/IR Protocol for Hisense® Prosumer TV") describes a fixed-length ASCII command protocol with 4-character opcodes, an optional per-TV client identifier, a configurable parameter field, and a 1-byte checksum terminated by CR. It also documents a large catalogue of discrete IR codes, but those are out of scope for a serial-control spec.

Transport

protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no login/password/auth procedure in source

Frame format (per source):

• Set: S [CLIENT_ID(3)] [COMMAND(4)] [DATA(4)] [CHECKSUM(1)] CR
• Query: Q [CLIENT_ID(3)] [COMMAND(4)] ???? [CHECKSUM(1)] CR
• Ack: [CLIENT_ID(3)] : ACK [DATA(4)] [CHECKSUM(1)] CR
• CLIENT_ID = ALL for broadcast, or the last 3 bytes of the TV's Ethernet MAC address (e.g. 5FA) for a single unit.
• COMMAND = 4 ASCII letters, e.g. POWR, INPT, PMOD.
• DATA = 4 ASCII characters (0-9, A-Z, #, ?). ???? is the query placeholder.
• CHECKSUM = 1 byte; the 8-bit sum of every byte in the frame including the checksum byte equals zero.
• Termination = carriage return (HEX 0x0D). Colon separator = 0x3A. Communication code is ASCII. Protocol is case sensitive.

Traits

- powerable   # inferred from POWR/PWRE/PBTN command examples
- routable    # inferred from INPT/INPM/POIS input-routing command examples
- queryable   # inferred from query command examples (? INPT, ? PMOD, ? VOLM, etc.)
- levelable   # inferred from VOLM/BRIT/CONT/COLR/TINT/SHRP/BKLV/MAVL/VLFL level-control examples

Variables

# No additional continuous variables beyond those exposed as discrete actions
# (BRIT, CONT, COLR, TINT, SHRP, BKLV, VOLM, MAVL, VLFL). Source documents
# only fixed-step set/query commands; no separate "set-without-action" variables.

Safety

confirmation_required_for:
  - restore_factory_settings  # RSET9999 - wipes all custom settings
interlocks: []
# UNRESOLVED: source does not document other safety warnings, electrical interlocks,
# or power-on sequencing requirements beyond the "Power On Command Enable" install flag.

Notes

• TV setup requirement (per source): RS-232 control is not enabled by default. The user must enter the Custom Install menu (Quick Settings → enter 7 3 1 0 → set Custom Installation = Enable). For RS-232 to power the TV on from standby, the Power On Command setting must also be set to Enable in that menu.
• Multiple-TV addressing: The source documents two addressing modes — ALL (broadcast to every TV on the serial bus) and the last 3 bytes of the TV's Ethernet MAC address (e.g. 5FA). The TV's MAC is found via Menu > Network > Network Information.
• Power-on command enable is not available in STANDBY mode (per source V3.1 release note for the PWRE command).
• Example sequence from source (ASCII form): S5FAPOWRON##[chk]\r enables remote power-on; the TV replies 5FA:WAIT####[chk]\r then 5FA:OKAY####[chk]\r. S5FAPOWR0001[chk]\r then turns the TV on. The "POWR" command alone (without PWRE first) will fail to wake a TV that is in standby.
• Discrete IR codes: The source also documents a large catalogue of discrete IR codes (NEC protocol, 32-bit custom codes with 04 FB prefix) covering power, input select, digits, navigation, picture/sound mode toggles, aspect ratio, channel list, sleep, menu, and the colored buttons. These are an alternative control path; the source does not specify a transport layer that delivers them over IP.
• No TCP/IP control documented. The user's "Known protocol: TCP/IP" hint is not supported by the source — the Ethernet reference is limited to MAC-derived client IDs and the TV's network info menu. Any TCP control would require a separate, uncataloged command set.
• Cable note: For PC/controller connection without a DB9 port, the source specifies a USB-to-Serial adapter (sold separately).
• DB9 pinout (TV female chassis-mount, DCE): 1=RI, 2=TXD, 3=RXD, 4=DSR, 5=GND, 6=DTR, 7=CTS, 8=RTS, 9=Power Input/DCD. The "Power Input" pin is not a serial signal and should not be driven.
• Command mnemonics are case-sensitive (per source).

summary: "All 68 spec actions traced to source (dip-safe re-verify). (3 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "User-stated protocol was TCP/IP, but the source only documents RS-232/IR. The \"Ethernet MAC address\" referenced by the source is used as a client-identifier value inside the RS-232 frame, not as a network control protocol."
- "Specific HiSense 5U8K model identifier is not stated in the source; the source covers the \"Prosumer TV\" line in general."
- "source does not document other safety warnings, electrical interlocks,"
