Generally, you will never have to modify the delay sliders. The following circumstances necessitate adjusting the sliders. If you are completely unable to get a value of FF back from the EAS, then adjusting the Idle delay to a quicker setting can some times help. If you are constantly getting 255 values when trying to read the faults or recalibrating, try to adjust the One Byte Delay slider. Usually making the delay just a bit longer will help.
