ViewSonic ViewBoard IFPxx60 Control Spec

Summary

ViewSonic ViewBoard IFPxx60-series interactive flat panel. Dual control interface: RS-232 (9600/8N1) and LAN (TCP port 5000). Binary command protocol, 9-byte Set/Get packets, ASCII reply codes +/-/r. Includes remote control pass-through mode.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # not stated explicitly; RS-232 spec lists only baud/data/parity/stop
addressing:
  port: 5000

  type: none  # inferred: source states "Logon Credentials: No"

Traits

traits:
  - powerable      # inferred: Power On/Off set + power status get
  - queryable      # inferred: Get-Function section enumerates many status queries
  - levelable      # inferred: Brightness/Volume/Contrast/Bass/Treble/Balance set+get
  - routable       # inferred: Input Select with enumerated source list

Actions

# Command packet template (9 bytes):
# Length=0x38 | ID2 | ID3 | Type | Cmd | V1 | V2 | V3 | 0x0D(CR)
# Type: 0x73='s' Set, 0x67='g' Get. ID default "01" = 0x30 0x31.
# Reply: 0x2B='+' valid (Set), 0x2D='-' invalid (Set), 0x72='r' valid (Get reply).
# Below `{id2}{id3}` = 2-byte ASCII display ID (default 0x30 0x31).

Macros

# No multi-step sequences described in source. Removed.

Safety

confirmation_required_for:
  - restore_default   # factory reset, irreversible
  - set_power         # power state change
interlocks:
  - "POWER Lock enabled: display ignores IR POWER key, but RS-232 SET POWER still works. Lock cannot be cleared via OSD reset; auto AC power-on behavior under power-lock."
  - "Under POWER Lock: display will not enter power-saving on no-signal, and will not auto-off after 15 min no video."
  - "IR Pass-Through POWER key: when display OFF and IR POWER received, display turns ON then forwards code; when ON, forwards code then turns OFF."
  - "Button Lock: locks all front-panel + RCU keys except POWER; RS-232 Set functions still work."
  - "Menu Lock: locks MENU key on panel + RCU; Factory/Hospitality modes may still be reachable via MENU-combo."
# UNRESOLVED: no explicit voltage/current/power-spec or external-interlock text in source.

Notes

• Source doc caveat: the supplied refined markdown is titled "IFP32 RS-232 Protocols". It is being applied to the IFPxx60 family based on the recovery-memo inference that ViewBoard families share a common protocol; this is not stated by the manufacturer. A spec verifier may downgrade for this reason.
• Display ID addressing: ID is 2 ASCII bytes, range 01~98 (default 01). ID 99 broadcasts to all displays — only display #1 replies. ID is configured via OSD.
• Packet terminator: every command ends with 0x0D (CR). Set/Get packets are 9 bytes (length byte = 0x38 = ASCII '8'); Get-valid reply is 9 bytes; Set/invalid reply is 5 bytes (length 0x34 = ASCII '4').
• Brightness/Volume special values: 900=decrement, 901=increment (relative).
• Hex input encoding: Value bytes are ASCII digits of the parameter, not raw binary (e.g. value 76 → bytes 0x30 0x37 0x36).
• Source inconsistencies flagged: (1) Color Mode and Backlight On_Off both show Hex 0x29 (one is a typo); (2) Get-Menu Lock shares cmd l/0x6C with Get-Power Status; (3) Get-RS232-Version example uses cmd 6/0x36 colliding with Get-IP-Address; (4) Backlight row shows Command Type A/a instead of s/g.
• Connector: DSUB-9 male or 3.5mm barrel (tip=TXD, ring=RXD, sleeve=GND). Null-modem cable required. Pin 9 supplies +5V/2A for vendor dongle.

Spec emitted. 60+ actions enumerated (all Set/Get rows + WoL + IR pass-through). Inferences marked. Source ambiguities flagged in Notes.

## Known Gaps

```yaml
- "source file titled \"IFP32 RS-232 Protocols\" — protocol compatibility with IFPxx60 inferred from product-family naming/doc structure, not stated explicitly by manufacturer. Specific model SKUs (IFP6560/IFP7560/IFP8650) and their exact firmware/driver support not verified."
- "no explicit voltage/current/power-spec or external-interlock text in source."
- "protocol compatibility with IFPxx60-series inferred, not stated."
- "source ambiguities in command-code table (see Notes)."
- "flow_control not stated in source (defaulted to none)."
- "firmware version compatibility not stated."
- "voltage/current/power specs not in this document."
