FAST Switch FAST-XFI Calibration

A single toggle switch can be used to access calibration files 0 and 1. Simply wire ?Cal Select Input #0? to ground through the switch. Using two toggle switches will give access to all four calibration files. Wire ?Cal Select Input #0? to ground through the first switch and wire ?Cal Select Input #1? to ground through the second switch. The switches would then be set as shown above to select the desired calibration file. A BCD encoder is a switch that will ground the inputs in the required pattern. ?Cal Select Input #0?, ?Cal Select Input #1? and a ground are connected to the switch according to the manufacturer?s instructions. All four calibration files can be selected with this type of switch.
