Rotel RSX-1058 RS-232 / IP control commands

Summary

The Rotel RSX-1058 is a multi-zone A/V surround receiver controllable via RS-232C using a binary HEX protocol. Commands use a fixed frame (Start 0xFE, Count, Device ID 0xC8, Type, Key, Checksum). Supports main zone plus 3 additional zones with independent power, volume, source selection, and tuner control. Unsolicited feedback strings mirror the front-panel display on any state change.

Notes

Binary HEX protocol — all commands are raw byte sequences, no ASCII text commands.
Checksum algorithm: (Count + DeviceID + Type + Key) mod 256. Count is always 0x03 for standard commands.
Meta encoding: byte value 0xFD in data must be sent as FD 00; byte value 0xFE must be sent as FD 01. This prevents false start-byte detection.
No carriage return or line feed after commands.
Device ID is fixed at 0xC8.
Type 10 commands affect all zones simultaneously in multi-zone installations; use zone-specific types (14/16/17/18) for discrete zone control.
Zone 2/3/4 status bits in feedback flags were added in Main software V1.2.0.
Volume direct main zone range: 0x00-0x5F (0-95). Zone 2/3 max sampled at 89, Zone 4 max sampled at 80.
Numeric key byte mapping: digit 1-9 → key 0x2A-0x32, digit 0 → key 0x33 (i.e., key = 0x29 + digit_index where digit_index = digit for 1-9, 10 for 0).
