Below is an illustration of a LED/switch bay from the user’s perspective.
Figure 2-14. LED/Switch Modules
The LED/switch controller card is a 4100 slave that mounts behind two LED/switch
modules. The LED/switch controller handles up to 64 switches and 64 LEDs on the
modules and communicates their status to the 4100 CPU. When a button is pressed on a
module, the controller acknowledges the signal and reacts according to how that switch
was configured via the 4100 Programmer.
