  - serial
  - tcp
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
addressing:
  port: 10008  # default LAN data port
auth:
  type: credentials  # UNRESOLVED: login procedure described (username + password), credentials not specified in source
  notes: "LAN login: send [username]+[space], receive [Password:], send [password]+[space], receive [OK]. Empty username/password permitted if unset. Send [BYE] + [space] to disconnect."

Actions

# Command format: C1 C2 C3 C4 P1 P2 P3 P4 [return code 0DH 0AH]
# Parameter field is 4 chars, padded with spaces if needed.
# Direction W = write/set, R = read via "????" param, WR = both.

Variables

# No settable parameters outside discrete actions above.

Events

# No unsolicited notifications documented.
# LAN: [Login: ] prompt on connect, [Password: ] after username, [OK] after password, [Goodbye] on BYE.

Macros

# No multi-step sequences documented (login handshake is transport-level, see Transport.auth.notes).

Safety

confirmation_required_for: []
interlocks:
  - command: all_reset
    notes: "Monitor restarts after ALL RESET. Wait >= 1 minute before sending next command."
  - command: power_set
    notes: "Perform buffer clear at sender before power On/Off. Wait >= 1 minute after power On/Off before next command."
timing:
  response_timeout: ">= 10 seconds recommended"
  inter_command_interval: ">= 100 ms between response and next command"

Notes

  • Command field is 4 prescribed alphanumerical chars; parameter field is 4 chars (0-9, +, -, space, ?), padded with spaces.
  • Wrong: VOLM30 — Right: VOLM 30 (4-char param, space-padded).
  • Direction "W" = set/write, "R" = read via ????, "WR" = both.
  • Commands marked – usable only when power on. * not usable in standby / input-signal-wait when Control Terminal=RS-232C or Power Save Mode=Low Power.
  • RS-232 requires cross cable between COM port and monitor RS-232C terminal.
  • ERR returned for unknown command or command unusable in current state. Nothing returned if connection bad. Resend recommended on ERR from interference.
  • LAN auto-disconnect after "Auto Logout Time" elapses with no communication.
  • Same command set used for RS-232C and LAN.

summary: "All 17 spec actions map to literal mnemonics (POWR, INPS, VOLM, MUTE, WIDE, INF1, SRNO, RSET, VLMP, PXCK) in the source command table, with shapes and enums aligned, and transport values (9600 baud, port 10008, login handshake) verified verbatim. (3 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "voltage/power specs not in source. Firmware version compat not stated."
- "login procedure described (username + password), credentials not specified in source"
- "firmware version compat not stated. Voltage/power specs not in source. Credentials for LAN auth not specified (login procedure described but no default user/pass). Protocol version not stated. Return code byte sequence noted as 0DH 0AH or 0DH in one place — ambiguous, treat as CRLF."
