Notes

• Frame format: commands are hex byte sequences. Byte positions 3-4 of fixed-form commands carry ID1 (Control ID) and ID2 (Model code); the source's literal examples assume ID1=00h, ID2=00h. Checksum byte (CKS) is the low-order 8 bits of the sum of all preceding bytes.
• Success response prefix = 20h + command-type byte; error response prefix = A0h + command-type byte. ERR1/ERR2 byte pairs carry failure reasons (see source section 2.4).
• Supported serial baud rates: 115200, 38400, 19200, 9600, 4800 bps. Source does not designate a default.
• TCP control port 7142 (explicitly stated for wired/wireless LAN command transport).
• ID2 (model code) is model-dependent and not stated in source for Pnme502.
• Several commands reference a vendor "Appendix: Supplementary Information by Command" for input-terminal and sub-input value maps; that appendix is not present in the refined source text and those value lists are therefore unresolved.
• Commands 078-2 RUNNING STATUS REQUEST, 078-4 MUTE STATUS REQUEST, 078-5 MODEL NAME REQUEST, 078-6 COVER STATUS REQUEST show no explicit error-response line in the source; the standard A0h-prefixed error frame is presumed by convention but not literally documented for those rows.

Known Gaps

- "firmware version compatibility not stated in source"
- "default baud rate not stated (source lists 5 supported rates, no default marked)"
- "ID2 model code value for Pnme502 not stated (varies by model)"
- "input-terminal DATA01 value map referenced to \"Appendix\" not present in refined source"
- "source documents no unsolicited notifications; all responses are replies to commands"
- "source states POWER ON and POWER OFF block all other commands during execution (including cooling time), but does not describe formal interlock sequences or power-on ordering requirements"
- "firmware version compatibility not stated"
- "default baud rate not designated among the five supported rates"
- "ID2 model code value for Pnme502 not in source"
- "input-terminal DATA01 value map (vendor Appendix not in refined source)"
- "eco-mode DATA01 value map (vendor Appendix not in refined source)"
- "base model type value map (vendor Appendix not in refined source)"
- "sub-input setting value map for PIP/PbP (vendor Appendix not in refined source)"
