Reverse Switch
The PCM9X features a servo reverse function. This allows the user to electronically
reverse the direction of a channel. Servo reversing is available for all 9 channels of
the PCM9X. In Function Mode, use the scroll bar to select Reverse Switch and
access by pressing the scroll bar.
Sub Trim
The sub trim function allows you to individually fine tune the centring of all 9
channels on the PCM9X within a range of + or - 125% (+ or - 30 degrees
servo travel). It is not a good idea to use excessive sub trim as you can
eventually overrun the maximum travel of your servos.
In Function Mode, use the scroll bar to select Sub Trim and access by pressing
the scroll bar.
Travel Adjust
The purpose of Travel Adjust, also known as endpoint adjustment or
adjustable travel volume, is to offer you precise servo control deflection in
either direction of servo operation.
The travel adjust range is from 0-150% (0 degrees to 60 degrees) from neutral
and it can be adjusted for each direction individually. The factory default (data
reset) value is 100% for each direction of servo travel.
