AI4AVSummary
Rotel RC-1590 stereo preamplifier controlled via an ASCII command protocol over RS-232 (115200 8N1, no flow control) and TCP/IP (port 9590). This spec covers the V2.0 command set (main CPU firmware V1.40 and newer) and the legacy V1.0 command set (pre-V1.40), including control commands, feedback queries, and response string formats as documented in Rotel's "RC-1590 RS232 / IP ASCII Controller Command List" (spec version 2.00, July 16, 2019).

Actions
# All commands MUST be terminated with "!" (no spaces, no CR/LF after it).
# Commands marked (both) use the same ASCII string on all firmware revisions;
# only the feedback terminator differs ("$" on fw >= 1.40, "!" on older fw).

# resets the unit to factory defaults; source attaches no warning to it.
Notes
- All commands must be terminated with the "!" character. Do not include spaces, carriage returns, or line feeds — only the terminating "!".
- Feedback strings terminate with "$" on firmware V1.40+ (protocol V2.0) and "!" on older firmware (protocol V1.0). Variable-length display text uses a decimal byte count (covering text data only, not the length digits or the "," separator) followed by "," and the text, with no terminating character. The control application must parse all three forms.
- RS-232 hardware does not support flow control; care must be taken when sending/receiving to avoid packet loss. Serial settings: 115200 baud, 8 data bits, no parity, 1 stop bit, no handshaking, string data type.
- IP control: commands accepted via TCP port 9590; responses return on the same port. Command/response format identical to serial.
- Protocol revision break: as of main CPU software V1.40, several commands and ALL feedback strings changed (see spec Sections 3, 4, Appendix A). Connected control systems must be updated to the new protocol before updating RC-1590 firmware. RS-232 settings and IP port are unchanged between V1.0 and V2.0.
- Rotel Link RCD: the input selected for ROTEL LINK RCD in the setup menu returns a
_cd-suffixed source string (e.g.source=coax1_cd$instead ofsource=coax1$). - PC-USB transport controls (play/pause/track) only function when the RC-1590 is set to USB 2.0 mode (
pcusb_class_2!). - Special character mapping (spec Section 5): some display characters are represented as 2–3 hex byte sequences in feedback (e.g. EE 82 85, EE 82 82 for play/arrow symbols, EE 80 80 EE 80 81 EE 80 82 for END). Parse display text accordingly.
- Volume scale is 1–96 (corrected in spec v1.11 from an earlier 1–86).

summary: "All 136 spec action units (power/volume/source/tone/balance/dimmer/transport/menu/numeric/system V2.0 + V1.0 legacy and feedback queries) appear verbatim as ASCII tokens in the refined Rotel RC-1590 command list; transport (115200 8N1, TCP 9590) matches the Connection/IP Control Settings tables. (4 unresolved item(s) noted in Known Gaps.)"
Known Gaps
- "no IP addressing details (DHCP/static, network config commands) beyond TCP port stated in source"
- "source contains no safety warnings, interlock procedures, or"
- "no IP network configuration commands (DHCP/static assignment) documented in source"
- "command acknowledgement/error behavior for invalid commands not documented in source"
