I/O Input relationship to Servo output
Here is a table that lists the 8 servo positions along with the I/O position that corresponds to each servo.
1 SERVO 1 AUX I/O 1
2 SERVO 2 AUX I/O 2
3 SERVO 3 AUX I/O 3
4 SERVO 4 AUX I/O 4
5 EXP 1 MAIN I/O 1
6 EXP 2 MAIN I/O 2
7 EXP 3 MAIN I/O 3
8 EXP 4 MAIN I/O 4
EXP port numbering is backwards
Notice that the numbering on the EXP port goes right-to-left. All the other ports go left-to-right.
Servos will hardly move out of the box
The default servo travel is very small, to help prevent any accidents while getting things
configured. Use the Remote Align board to adjust the travel endpoints.
Servos are only “powered” when moving
The servos are set to “Power Off When Stopped”.
This means that the board stops sending the
position (pulse) signal to the servo after the servo has reached the position setpoint. When the servo
does not receive signal pulses, it stops driving its internal motor. This feature prevents any annoying
servo buzzing.
Have fun!
I always here to help if needed.
