Enabling/Disabling
LEDs using jumper
The Isolated LLAI Module includes a jumper (W2) to enable/disable
LEDs on the module. Normally, you should keep the LEDs enabled,
but if power conservation is an issue, you could disable the LEDs.

Jumper Purpose Description
W2 Enables/disables LEDs on
module
Pins 1-2 installed = Enable LEDs (Factory default).
Pins 2-3 installed = Disable LEDs
