Sharp PN-M Series Control Spec

Summary

Sharp PN-M Series professional displays support external control via RS-232C serial and LAN (Telnet-style TCP) connections. Commands use a fixed 4-character command field plus 4-character parameter field. Up to 4 monitors can be daisy-chained via RS-232C with individual ID addressing (1–255). This spec covers power, input selection, picture adjustment, PIP/multi-screen, scheduling, LAN setup, and diagnostic queries.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 38400
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
addressing:
  port: 10008
auth:
  type: credential
  method: telnet_login
  description: >-
    LAN connection requires Telnet-style login sequence.
    Connect to IP:10008, receive "Login:" prompt, send username + space,
    receive "Password:" prompt, send password + space.
    If credentials not set, send space for each.
    Successful login returns "OK ". Send "QUIT " to disconnect.
    RS-232C has no authentication.

Traits

traits:
  - powerable     # inferred from POWR command
  - queryable     # inferred from multiple R-direction commands
  - routable      # inferred from INPS input selection and MWIP PIP source
  - levelable     # inferred from VOLM volume and VLMP brightness controls

Notes

• Command format is 4-character command field + 4-character parameter field, terminated with return code (0DH 0AH or 0DH). Parameters must be exactly 4 characters, padded with spaces.
• Repeater control: setting the 4th parameter character to "+" broadcasts to all daisy-chained monitors.
• Query commands (Direction R) use "?" characters as parameters to read current values (e.g., VOLM????).
• Up to 4 monitors can be daisy-chained via RS-232C with ID numbers 1-255.
• RS-232C and LAN control cannot be used simultaneously (select via CTLS command).
• Baud rate default is 38400 bps; configurable via SETUP menu BAUD RATE setting.
• Minimum 100 ms interval required between command response and next command transmission.
• LAN control uses same RS-232C command set over Telnet-style connection on port 10008.
• LAN login required: connect to port 10008, authenticate with username/password, then send commands.
• When POWER SAVE MODE is ON, some RS-232C commands and LAN control are unavailable in standby mode.
• Response codes: "OK" (success), "ERR" (invalid command or wrong state), "WAIT" (processing, wait 10+ seconds), "UNSELECTED" (RS-232C/LAN SELECT is set to the other interface).
• IDSL targets one next command; IDLK targets all subsequent commands until canceled.
