Question What is the A/B switch on the D2-12TR used for?
Answer It is used because there is not enough space on the D2-12TR for 12 LEDs. When the switch is in the A position, the LEDs indicate the status of the first bank of 6 outputs. When the switch is in the B position, the LEDs indicate the status of the second bank of 6 outputs.
