I have just updated the instructional video for the 3 Position servo driver.
The software has been updated, a continual process to meet the needs of users.
When DIP Switch 6 when turned ON this changes the servos to 2 position, from the default 3 position when DIP Switch 6 is OFF.
When DIP Switch 5 is turned ON, the range of servo travel is reduced. This is useful for some model Semaphore Signals that require very little servo travel. The speed of travel has also been reduced. This is useful for signals from San Mateo Line sanmateoline.com.au that could be easily damaged by servos traveling too far or too fast.
Please let me know if any of my electronics could be modified to be more useful for your model railways.
