JEwaldt.LgDisplay

A two-way Crestron SIMPL# Pro driver for LG commercial displays, using the LG serial control protocol (the ka/kf/ke/xb command set) over serial-over-IP — a serial-to-Ethernet gateway or the display's native LAN control port (default 9761). Verified against the LG 60WL30MS-D.

Install

dotnet add package JEwaldt.LgDisplay

Use

using JEwaldt.LgDisplay;

var tv = new LgDisplay("192.168.1.80", 9761, setId: 1, name: "Sit Room 2nd Display");
tv.FeedbackChanged += (s, e) =>
{
    // tv.PowerIsOn, tv.Volume, tv.Muted, tv.SelectedInput
};
tv.Connect();

tv.PowerOn();
tv.SetInput(LgProtocol.Input.Hdmi1);
tv.SetVolume(35);
tv.Poll();            // refresh power / volume / mute / input feedback

Call tv.Dispose() on teardown.

Control surface

PowerOn / PowerOff / PowerToggle · SetVolume / VolumeUp / VolumeDown · MuteOn / MuteOff / MuteToggle · SetInput / SetInputRaw · SendKey(LgProtocol.RemoteKey) (IR menu navigation — Menu/Up/Down/Left/Right/Ok/…) · Poll · SendCommand(c1, c2, data) (raw escape hatch for any LG command).

Feedback (properties + the FeedbackChanged event)

PowerIsOn · Muted · Volume · SelectedInput.

Inputs (LgProtocol.Input)

Hdmi1, Hdmi2, Hdmi3, DisplayPort, Ops, Av, Component, RgbPc.

Input codes vary by model. The xb data codes in LgProtocol are the common LG values; confirm them against your model's manual. SetInputRaw("90") lets you send an exact code without touching the enum.

Protocol

  • Command: {c1}{c2} {SetID} {Data}\r — e.g. ka 01 01\r (power on, set 1).
  • Acknowledgement: {c2} {SetID} OK{Data}x — e.g. a 01 OK01x. NG = rejected.
  • One command is sent at a time and gated on the ack (500 ms timeout); replies are dispatched by their command character, so a late ack still updates the right feedback.
  • The TCP transport auto-reconnects every 5 seconds.

FeedbackChanged fires on a Crestron worker thread — marshal to your own context if a handler touches shared state.
