Servo Screen – This screen is used to configure the servo outputs if you are in dead rail mode. Each servo has a function code associated with it, a reverse flag and a low and high limit setting. The function code for servo 0 has no effect at the moment but 2 and 3 are used when the servos are set to coupler mode. In coupler mode, issuing that function code (from say the aux button on the PT) will set the servo to either limit. If the function is on, the servo will be driven to the high limit, if off, it will go to the low limit. These limits are also used in ‘steam’ mode. In this case, servo 0 follows the throttle (28 step mode works best here) and the direction controls servo 1. Reverse is limit low, forward is limit high.
