AI4AVSummary
The Christie SUHDxx V3 Series is a line of large-format display panels controllable over RS-232 serial. This spec covers the binary RS-232 command/response protocol used to query display state, control power, switch input sources, adjust image parameters, configure multi-window layouts, and manage the RTC schedule. Ethernet is supported for status alerts only and is not used as a control transport in the documented protocol.
Transport
protocols:
- serial
serial:
baud_rate: 115200
data_bits: 8
parity: none
stop_bits: 1
flow_control: none
auth:
type: none # inferred: no auth procedure in source
Frame format (host → display):
- Read:
07 IDT 01 CMD 08(7 bytes) - Write:
07 IDT 02 CMD VAL 08(8 bytes) STX = 0x07,ETX = 0x08IDT= do not care; source examples use0x01CMD= 3 ASCII bytes per the command table- Return from monitor uses
Type = 0x00and echoes the CMD with the resulting value
Worked example (power on):
- Transmit:
07 01 02 50 4F 57 01 08 - Return:
07 01 00 50 4F 57 01 08
Traits
- powerable # POW command, on/off
- routable # MIN input select, multi-window PSC/PIN/PIO/PIP
- queryable # W/R commands, dedicated R commands (SER, MNA, GVE, RTV)
- levelable # BRI, BRL, CON, SHA, HUE, SAT, USR/USG/USB, UOR/UOG/UOB
Actions
# Every W/R command from the source is enumerated as separate set/query actions.
# Read-only commands (SER, MNA, GVE, RTV) are emitted as kind: query.
# Command payloads use the literal byte format from the source: "07 01 TT CMD VAL 08"
# where TT = 01 (read) or 02 (write), CMD = 3 ASCII bytes (hex), VAL = hex byte.
# IDT = 0x01 per source examples; "do not care" per spec.

Variables
# No continuous settable parameters beyond what is exposed as discrete Actions above.
# (Daily schedule On/Off hour/minute are exposed as discrete set_* actions, not as
# composite variables, because the source treats each as an independent RS232 command.)
Events
# Ethernet alert messages (Power Status Alert, Source Status Alert, Signal Lost Status)
# are mentioned in the Communication menu as toggleable features, but the source does
# not document the alert packet format, transport, or destination. They are likely
# outbound TCP or UDP packets, but the source gives no protocol-level detail.
#
# UNRESOLVED: Ethernet alert packet format and transport - source describes the
# features as menu options with On/Off toggles only; no payload schema, port, or
# destination documented in the visible source. Marking as unresolved.
Macros
# UNRESOLVED: source does not document any user-defined or built-in macro sequences.
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not contain explicit safety warnings, interlock procedures,
# or required power-on sequencing. The Power saving / Wake Up From Sleep behavior is
# operational rather than safety-related and is documented in the Notes section.
Notes
Sleep mode behavior. The display enters Sleep Mode by default after five minutes with no signal. With the default Wake Up From Sleep = VGA Only, RS-232, DisplayPort, and HDMI inputs are inactive during sleep. To retain control during sleep, set the mode to Digital, RS232, Ethernet (0x01) or Never Sleep (0x02). The Power (POW) command is marked ▲ in the source as valid in power-save/off mode under this same precondition.
Frame protocol. All RS-232 commands use the same 7- or 8-byte frame: 0x07 IDT Type CMD [Value] 0x08. IDT is documented as "do not care"; the source examples consistently use 0x01. The monitor's reply echoes the frame with Type = 0x00 and either the executed value (write) or current value (read).
Ethernet usage. The display has a built-in Ethernet port (RJ-45 labeled "LAN / Communication port"), but the source only documents its use for status alerts. No TCP/UDP/JSON-RPC control command set is provided. The IP Address settings menu supports static IP (default 192.168.2.1) or dynamic IP, and the network can be disabled via the Enable Network menu option (default Off).
Command table source. Some Saturday schedule rows (TFH, TFM) and the DisplayPort 1 EDID row (ED1) appear to be present in the original vendor manual but were truncated in the extracted text used to build this spec. They are marked UNRESOLVED above and should be verified against the full vendor PDF or on-device command table before implementation.
IDT value. Source says "Do not care". The example transactions all use IDT = 0x01. Some hosts may treat the byte as a device address and use other values; behavior with non-0x01 IDT is not validated by the source.
