Does anyone know what additional electronics are needed to connect ALPS rotary encoders to the FSBUS keys pcb? and if you do where can I purchase or get a layout to build a board?

If it is an Alps "gray code" or "phase shifted" encoder where the pulse comes from all pins, but it is connecting one of the pairs first depending on the direction turned, then you need some extra stuff. Search this forum for "redec" circuit and you find lots of discussion about the topic.//Tuomas

In other words: if you have a alps SRBM1L, you can connect it directly to FSKEY, they have 2 connections for left and two separate connections for right. They cost 7 euros (simcockpit.nl).Most other (cheaper) Alps rotary encoders need a REDec for smooth handling. Alternatively Knitter encoders perform smoothly without REDec. The cheaper Alps types (with 3 connectors) can be connected to FSKEY, but will malperform when turned too quickly or too slow.
