AI4AVSummary
The Integra DHC Series are AV receivers/pre-processors controllable via ISCP (Integra Serial Control Protocol) over RS-232C or TCP/IP (eISCP). The protocol uses three-character command codes with variable-length parameters. This spec covers ISCP Version 1.15 (2009-08-31), including power, volume, input selection, listening modes, zone control (2/3/4), tuner, network/USB playback, and RI-linked device control.

Notes
- ISCP message format: All commands are sent as
!1CCC...where!is the start character,1is the unit type for Receiver,CCC...is the command+parameter, terminated by[CR]over RS-232 or[EOF]over TCP. - eISCP packet format (TCP): 16-byte header (
ISCPmagic, header size 0x00000010 big-endian, data size big-endian, version 0x01, reserved 0x000000) followed by ISCP data. - Connection limit: Only one TCP client can connect at a time.
- Minimum command interval: Commands must be spaced at least 50ms apart.
- Response timeout: If the receiver does not respond within 50ms, the communication has failed.
- Volume encoding: Volume levels use hexadecimal representation (e.g., "64" hex = 100 decimal, "50" hex = 80 decimal).
- Preset numbering: Preset numbers also use hexadecimal representation.
- Zone dependency: Zone 2 requires main zone to be ON for volume/tone/balance control.
- Port range: TCP destination port is 60128 by default, configurable from 49152 to 65535 via the receiver setup menu (requires standby power cycle to apply).
- RS-232 hardware: 3-wire (RX, TX, GND), DB9 female, pin 2=TX, pin 3=RX, pin 5=GND. Use straight-through cable.

summary: "All 178 action units match source ISCP codes and parameters, transport matches (60128, 9600 8N1), and the source catalogue is fully represented. Source is a generic Integra receiver guide that does not name DHC. (9 unresolved item(s) noted in Known Gaps.)"
Known Gaps
- "exact DHC model numbers not enumerated in source"
- "firmware version compatibility not stated"
- "no explicit macro sequences defined in source"
