HiSense 75U75QGB Series Control Spec

Summary

RS-232 and IR control protocol for the HiSense Prosumer TV line, as documented in the vendor "RS-232/IR Protocol for Hisense® Prosumer TV" manual (rev V3.6, 17-Apr-2017). The 75U75QGB Series is not explicitly named in the source — the document is generic across the "Prosumer TV" product line and instructs the integrator to consult the device User Manual for model-specific support. Transport is RS-232 (DB9 D-sub female) at 9600 8N1, ASCII command/ack protocol, with a 3-byte client ID derived from the TV's Ethernet MAC address (last 3 hex bytes) or a broadcast ALL token.

Transport

# Source documents RS-232 only. No TCP/UDP/HTTP/port number present.
# IR section is documented but the spec format targets machine protocols;
# IR codes (Pronto CCF / NEC data) are listed in the source as a separate
# catalogue and are NOT serialized as AI4AV Actions.
protocols:
  - serial
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
  # Source: "Communication Code: ASCII code"
auth:
  type: none  # inferred: no login/password procedure in source

Traits

- powerable       # POWR, PWRE documented
- routable        # INPT documented (TV/AV/Component/HDMI1-4/VGA)
- queryable       # ??/???? query form on every command
- levelable       # VOLM, BRIT, CONT, COLR, TINT, SHRP, BKLV documented

Actions

# Source protocol frame (fixed length, 14 bytes + CR):
#   S/Q + 3-byte CLIENT_ID + 4-byte COMMAND + 4-byte DATA + 1-byte CHECKSUM + 0x0D
# "S" = Set, "Q" = Query. Checksum = 8-bit sum so the total frame (incl. CHECKSUM byte) = 0x00.
# Below, "command" uses ASCII form with placeholder; "checksum" / hex form are
# documented in the source per-row but are command-specific - the source does
# NOT expose a single formula. Implementers must compute the checksum per the
# rule above and consult the source's per-row hex columns.
#
# Generic (broadcast) variant: client_id = "ALL" - hex `41 4C 4C`.
# TV-specific variant: client_id = last 3 hex bytes of TV's Ethernet MAC.

Variables

# No settable scalar parameters distinct from the action set above. All settable
# values are exposed as parameterized actions in the Actions section.
# UNRESOLVED: remove this section if not applicable

Events

# UNRESOLVED: source does not document unsolicited notifications from the TV.
# The protocol is strictly command/response - controller sends a frame, TV sends
# one ACK back. There is no asynchronous event stream.

Macros

# UNRESOLVED: source does not document multi-step sequences. The closest analog
# is the TV Setup procedure (enable Custom Installation menu, set RS-232 port
# active, optionally enable Power On Command for wake-from-standby), but that
# is installer setup, not a device-driven macro.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or hazardous-state definitions. RSET9999 (factory reset) and POWR0000 (standby)
# are reversible; no parameter-set combination in the source is flagged as
# destructive or operator-confirmation-required.

Notes

• The source document is the generic "RS-232/IR Protocol for Hisense® Prosumer TV" (rev V3.6, 17-Apr-2017), not a 75U75QGB-specific manual. The doc itself states "Check User Manual for your specific TV to identify supported IR commands by model." This spec therefore represents the protocol as documented for the Prosumer TV product line; model applicability to the 75U75QGB is operator-assumed and not directly confirmed by the source.
• User-supplied metadata tagged "Known protocol: TCP/IP" — the source does not document any TCP/IP port, HTTP endpoint, or REST path. Only RS-232 (DB9 D-sub female, 9600 8N1 ASCII) is documented. The Ethernet MAC address derivation for the 3-byte client ID is the only networking-related evidence and is not sufficient to infer a transport. IP-based control is not serialized in this spec.
• IR section in the source documents ~50 discrete NEC-format codes (POWER, HDMI.1-5, VOL±, CH±, digit 0-9, navigation, etc.) plus their full Pronto CCF hex strings. These are out of scope for AI4AV Actions (IR is a separate transport, not a machine protocol) and are not serialized.
• Protocol frame: 14 bytes + CR(0x0D). Layout: OP(1) + CID(3) + COMMAND(4) + DATA(4) + CHECKSUM(1). CHECKSUM is the 8-bit sum such that the entire 14-byte frame including the CHECKSUM byte equals 0x00. The source does not give a closed-form expression — implementers must compute the checksum per row, or recompute from the per-command hex columns the source lists.
• Acknowledgement (ACK) format from TV: {CID(3)} : ACK(A-Z) {DATA(4)} {CHECKSUM(1)} CR. Common ACKs: OKAY (success), EROR (error), WAIT (busy). For example, the TV returns 5FA:OKAYHDM1[0xCB][0x0D] when the input query for client 5FA resolves to HDMI1.
• Per-row hex in the source distinguishes "TV-specific" (last 3 hex bytes of MAC = 465 shown) from "Generic" (ALL = 41 4C 4C shown) command forms — same command/data, different CID. Implementations targeting a single known TV should use the MAC-derived CID; broadcast scenarios use ALL.
• The protocol is case-sensitive (per source note).
• The source notes that the TV must have Custom Installation set to "Enable" in the on-screen menu (and "Power On Command" set to "Enable" if RS-232 wake-from-standby is required) before the RS-232 port becomes active.

summary: "All 68 spec actions matched to source commands with correct opcodes and shapes; 4 source commands (SPKM, B2BM, USBM, PSHF) not in spec but ratio 38/42=0.905 is above 0.9 floor and extra count ≤5. (8 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- SPKM
- B2BM
- USBM
- PSHF
- "source does not explicitly name the 75U75QGB; the model is being associated with this Prosumer TV protocol doc on operator-supplied evidence. The doc explicitly states \"Check User Manual for your specific TV to identify supported IR commands by model.\""
- "remove this section if not applicable"
- "source does not document unsolicited notifications from the TV."
- "source does not document multi-step sequences. The closest analog"
- "source contains no explicit safety warnings, interlock procedures,"
- "75U75QGB-specific model applicability — the source doc is the generic Prosumer TV protocol manual; no statement in the source confirms or denies that the 75U75QGB implements this exact command set. Operator should validate against the device User Manual or a live device."
- "TCP/IP control — user metadata claims TCP/IP as a known protocol, but the source contains no port number, no HTTP path, no JSON-RPC method, and no other TCP/IP evidence beyond the Ethernet MAC address being used as a client identifier. A separate network control protocol (if it exists for 75U75QGB) would need a different source document."
- "firmware version compatibility — source revision is V3.6 (2017); the 75U75QGB is a 2025-era product. No statement in the source or in the operator-supplied metadata confirms whether the 75U75QGB firmware implements this exact command set, a superset, or a subset. The 75U75QGB may use a different (Roku TV / Google TV / VIDAA) control path entirely."
