Some information on inputs used by DCS for TEDAC controls ?

[subseauk]

Hi all

Appologies if this is the wrong area to ask this but I am in the process of building a 3d Printed Apache CPG TEDAC unit and need some information regarding 3 specific controls fitted and what signal DCS requires to operate the associated item.

fIrst one is the OFF - DAY - NIGHT rotary switch on the top right of the TEDAC screen.

Second and Third is the GAIN & LEVEL rotary controllers.

I need to know what sort of signal input is accepted by DCS from these so I can install the correct parts ie Rotary Encoders or Potentiometers.

Any help would be greatly appreciated as these are the last 3 items I need to complete the project.

Rgds
