HiSense 55U75QG Series Control Spec

Summary

HiSense 55U75QG Series prosumer TV controllable via RS-232 serial and discrete IR. RS-232 uses a fixed-length ASCII protocol with 4-byte command and data fields, 8-bit checksum, and CR termination. Supports power, input routing, picture/audio settings, volume, and query for most parameters.

Transport

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

Protocol Notes

# Command format: [OP_DIR(1B)][CLIENT_ID(3B)][COMMAND(4B)][DATA(4B)][CHECKSUM(1B)][CR(1B)]
# OP_DIR: S=Set, Q=Query
# CLIENT_ID: last 3 bytes of Ethernet MAC address (hex), or "ALL" for broadcast
# ACK format: [CLIENT_ID(3B)]:[ACK(4B)][DATA(4B)][CHECKSUM(1B)][CR(1B)]
# ACK values: OKAY, EROR, WAIT
# Checksum: 8-bit sum of all bytes (including checksum) equals zero
# Termination: CR (0x0D)
# Protocol is case sensitive

Traits

traits:
  - powerable    # power on/off commands present
  - queryable    # query commands returning state present
  - routable     # input/output routing commands present
  - levelable    # volume, brightness, contrast, backlight control present

Notes

RS-232 port must be enabled in the TV Custom Install menu (Quick Settings > enter "7310") before serial control works. To allow power-on via RS-232 while in standby, the Power On Command must also be set to Enable in the Custom Install menu. The CLIENT_ID field uses the last 3 hex bytes of the TV's Ethernet MAC address for unicast commands, or "ALL" for broadcast. Connector is a female DB9 D-sub chassis mount. IR discrete codes (Pronto CCF format) are documented in the source but not represented here as they are one-way IR signals, not serial commands.
