hello... i had bought the SC16A and tested with three C40R servo motors using the GUI software provided. It could be no problem when tested with only 1 servo. However, the problem came out when tested with multiple servos. Once i control the 2nd servo the previous servo will turn without giving any command to it while the 2nd servo remain the same position. Later on the all of the servos cannot work at all by keep sending the commands. The servo will only start work again when the reset button is pressed.
So i wanna know that it is because of the problem of the servo controller SC16A or due to the servos?? But i have tested them independently it could work.
