Summary

RGB LED light alert bar with full-duplex ASCII serial control over RS-232 (3.5mm TRS), USB virtual com port, Telnet/TCP (port 23), and UDP (port 31936). Supports up to 9 user color presets (R/G/B levels 0–100) with looping via Time On / Next Preset parameters, P1 logic input contact-closure recall, and a password-protected web configuration page.

Transport

protocols:
  - serial
  - tcp
  - udp
serial:
  baud_rate: 9600  # factory default; configurable 1200-230.4K via R5= command
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: not stated in source
  # Note: USB virtual com port fixed at 115.2K baud, 8N1 (same protocol, separate transport).
addressing:
  port: 23  # Telnet/TCP default
udp:
  receive_port: 31936
  feedback_port: 31935
  # UDP command format prefixes device number: "{device}>cmd". Status responses sent
  # to directed broadcast IP at port 31935.
auth:
  type: none  # inferred: no login procedure for ASCII serial/TCP/UDP control path
  # Note: web page (Settings) is password protected; password derived from last 3
  # bytes of MAC (e.g. MAC 00-14-C8-20-01-BA -> "2001BA"). Separate from control protocol auth.

Traits

- levelable   # R/G/B output levels 0-100
- queryable   # numerous query commands return state (IY, NP=, MC, MN, HR, ID, IB)

Actions

# Command framing: ASCII ">" prefix + 2-char command + optional params + CR ($0D).
# UDP framing: "{device}>cmd" + CR. Responses: "<cmd ..." + CR/LF.
# Parameterized actions shown with variable part in braces.

Variables

# Preset structure: each preset n (0-9) holds red/green/blue levels (0-100),
# Time On (0 or 1-240 in 1/10s), Next Preset (preset number), and Name (≤10 chars).
# Set/queried via the Save/Recall/Set commands above rather than a single variable slot.

Events

# Status responses are unsolicited after control commands or user actions, delayed ~125ms,
# sending most recent status. May be enabled/disabled per connection type (EE= command).

Macros

# Looped presets: chain of ≥2 presets defined via Set Preset On Time + Set Next Preset.
# Recalling any preset in the loop initiates it; selecting Preset 0 or a non-loop preset stops it.
# Example red/blue flash loop documented in source (Preset 1: R50/G0/B0/T5/Next=2;
# Preset 2: R0/G0/B50/T5/Next=1).

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements. Contact-closure P1 logic input and DIP-switch
# programming sequences described but not marked as safety interlocks.

Notes

  • RS-232 3.5mm TRS pinout: Tip=TX, Ring=RX, Sleeve=Common. Accepts 0–5 VDC non-standard swing (IR port compatibility).
  • Status responses intentionally delayed ~125ms after control commands; can be enabled/disabled per connection type.
  • Web page password: default derived from last 3 bytes of MAC, entered uppercase without punctuation (e.g. MAC 00-14-C8-20-01-BA → 2001BA). Up to 20 chars after change. "Preset Ctl while logged out" option allows password-free preset recall while protecting settings.
  • UDP device addressing: command prefix {device}>cmd. Reserved device numbers (multiples of 256) broadcast to the next 255 units; device 4095 = all units. Device 0 = demo mode (steps presets 1–7, 3s dwell). Set via SW1 (bits 1–8) + SW2 (bits 1–4).
  • P1 Logic Input: 3 contact inputs + 12 VDC; modes 0 (unused), 1 (Trigger, presets 1–9 momentary/latching), 2 (Static, presets 0–7 latching), 3 (Static+1, presets 1–8 latching). Shorting pin to ground = logic high.
  • USB virtual com port fixed at 115.2K baud, 8N1 (separate from configurable RS-232 port).
  • Help command HE returns full command list from device.
