Pump and light GUI parameter questions

A few questions on the GUI:

  1. What does IN 2 do on the peristaltic pump array parameter? When I run the pump with it selected I get the following & nothing happens:
  2. What are the options A and B under the light parameters? image

Those only work if you have the other modifications to the system, like adding LEDs for optogenetics or adding a 3rd pump array for morbidostat applications. If you don’t have your system modded to do this, it won’t do anything.
