AI4AVSummary
The Integra DRX-R1.3 is a multi-zone AV receiver controllable via ISCP (Integra Serial Control Protocol) over RS-232C or Ethernet (eISCP over TCP). The protocol uses a fixed-format ASCII command structure: start character !, unit type 1 (Receiver), three-character command code, and variable-length parameter. This spec covers the eISCP (TCP) and RS-232 transport layers and all documented command groups: system power, volume, input selection, listening modes, tone control, tuner, network/USB playback, multi-zone control (Zone 2/3/4), and RI-system device passthrough.
Transport
protocols:
- tcp
- serial
addressing:
port: 60128
serial:
baud_rate: 9600
data_bits: 8
parity: none
stop_bits: 1
flow_control: none
auth:
type: none # inferred: no auth procedure in source
ISCP message format (RS-232):
Controller → Device: ! + unit type (1) + 3-char command + parameter + [CR]/[LF]/[CR][LF]
Device → Controller: ! + unit type (1) + 3-char command + parameter + [EOF]
eISCP packet format (TCP):
Header (16 bytes, big-endian): magic ISCP | header_size 0x00000010 | data_size | version 0x01 | reserved 0x000000
Data: ! + unit type (1) + 3-char command + parameter + [EOF]/[EOF][CR]/[EOF][CR][LF]
Notes:
- Connection must be held continuously; status notifications require a persistent connection.
- Only one TCP client connection at a time.
- Minimum 50 ms interval between received messages.
Traits
traits:
- powerable # PWR, ZPW, PW3, PW4 commands
- levelable # MVL, ZVL, VL3, VL4 volume; TFR/TCT/TSR tone controls; SWL/CTL sub/center levels
- routable # SLI, SLZ, SL3, SL4 input selector commands
- queryable # QSTN parameter on most commands
- muteable # AMT, ZMT, MT3, MT4 muting commands

Notes
- ISCP protocol version documented as 1.15 (31 August 2009). The protocol document covers a family of Integra/Onkyo receivers; not all commands may apply to the DRX-R1.3 specifically.
- Volume levels are expressed in hexadecimal (e.g.,
MVL32= decimal 50). - Preset numbers are in hexadecimal representation (e.g.,
PRS28= preset 40). - The eISCP header is 16 bytes, big-endian. Header size field is
0x00000010. - FF/REW Net-Tune commands must be sent continuously with no more than 100ms between codes.
- Minimum 50ms interval between received messages.
- TCP connection must be persistent to receive unsolicited status notifications.
- The tuner function (TUNER/XM/SIRIUS/HD Radio) is shared across MAIN and ZONE zones.
- Zone 2 has both shared (TUN/PRS) and separated (TUZ/PRZ) tuner control variants.
- XM, SIRIUS, and HD Radio commands are model-dependent and may not be available on all units.
- Japanese models have additional VOS (Video Output Selector) command.

Known Gaps
- "exact firmware versions compatible with this protocol version (1.15) not stated"
- "maximum concurrent connection limit beyond \"one\" noted in source — unclear if this refers to total TCP sessions or simultaneous controllers"
- "eISCP end-of-message character varies by model (\"[EOF]\" or \"[EOF][CR]\" or \"[EOF][CR][LF]\") — not pinned for DRX-R1.3 specifically"
- "no multi-step macro sequences described in source"
- "power-on sequencing requirements not stated in source"
- "fault behavior and error recovery sequences not stated in source"
- "exact eISCP end-of-message terminator for DRX-R1.3 not confirmed"
- "configurable TCP port range 49152-65535 stated but setup procedure not detailed"
- "tone commands for Front Wide (TFW), Front High (TFH), Surround (TSR), Surround Back (TSB), Subwoofer (TSW) documented but channel availability depends on speaker configuration"
- "Dolby Volume (DVL), Music Optimizer (MOT), Late Night (LTN), Re-EQ/Cinema Filter (RAS) commands documented but may vary by model"
- "RI system commands (CCD, CT1, CT2, CEQ, CDT, CDV, CMD, CCR, CDS) control external devices via RI link and are not direct receiver functions"
- "model-specific source not located"
