Assigning Channels to Buttons

Set which relay channels each Virtual Terminal button switches

Assigning Channels to Buttons

The Virtual Terminal main screen shows buttons. Each button switches one or more of the 8 relay channels (CH1–CH8). You set the channel assignment in the VT's EDIT mode — one button can switch several channels, and the same channel can be switched by more than one button.

Understanding Channel Assignment

Each button carries a channel selection — the relay channels it switches when pressed.

Example SetupBehavior
Button → CH1 onlyButton switches a single channel
Button → CH1 + CH2One button switches two channels
Two buttons → CH1Either button switches the same channel

Assigning Channels via VT

  1. On the tractor Virtual Terminal, press the EDIT soft key (cog icon). The buttons turn blue to show you're in edit mode.
  2. Tap the button you want to set up.
  3. Tap the channel buttons (CH1–CH8) to select which relays this button switches:
    • Selected = pressing the button switches this channel
    • Not selected = this channel is left alone
  4. Tap multiple channels to have one button switch several relays at once.
  5. Exit edit mode to save.

Example Configurations

One Button, Multiple Channels

To make a button switch both CH1 and CH2 (e.g., left and right work lights):

  1. Press EDIT and tap the button.
  2. Tap CH1 (selected).
  3. Tap CH2 (selected).
  4. Exit edit mode to save.

Now pressing that button switches both CH1 and CH2.

Two Buttons, Same Channel

To switch CH1 from two different buttons (e.g., one screen button and one grouped with another function):

  1. Press EDIT, tap the first button, select CH1, exit edit mode.
  2. Press EDIT, tap the second button, select CH1, exit edit mode.

Now either button switches CH1.

Clearing a Button's Channels

To make a button switch nothing:

  1. Press EDIT and tap the button.
  2. Tap each selected channel to deselect it.
  3. Exit edit mode.

Testing Your Configuration

You can verify a relay switches in two ways:

  • Press the button on the VT main screen and confirm the relay clicks.
  • Use the TEST function in the web interface to switch each output directly and check the wiring (see Web Interface Overview).

Where to Set the Rest

Channel assignment is one part of button setup. To set a button's name, icon, and mode (TOG/MOM), see Virtual Terminal Display. To choose toggle vs momentary behavior, see Button Modes.
