{CH} command

Declares a channel that is available on the remote device.

Each channel that is present will be reported in its own {CH} command.

Syntax

  • ch the number of the channel
  • Type the channel type. One of the following
    • A = Audio
    • ANI = Animation (lights)
    • CAB = Cab control
    • E = A predefined event
    • LC = Color Light
    • LM = Monochrome Light
    • OLED = OLED display (Small RemoteSign ESP based screens)
    • R = RemoteSign with color display, clock, audio, etc.
    • S = Sensors
    • SIG = Signal
    • TL = Traffic Light
    • TTS = Text to speech (Speech synthesis)

    • For type E, the name of the event (optional)

Note: To enable backward compatibility, traditional RemoteSigns and OLED signs must report their screen on channel 1. (So if Channel 1 is not type R it is not a traditional RemoteSign Windows.) Conversely all RemoteSign screen commands are regarded as being for channel 1.

Examples:

{CH}1␑ R
A classic RemoteSign

{CH}1 ␑ LM 
{CH}2 ␑ LM
A system with two independent lights

{CH}1␑ E ␑ Turntable position 3
Sending an {E}1 command will set the turntable to position 3
