Data Sheet

If you want to reprogram servo, you need to download the PC software (SCServo_Debug), and to

connect SCPC-2(Serial Control Programming Card) between servo and PC.

Half Duplex Asynchronous Communication

Half duplex UART is a serial communication protocol where both TxD and RxD can’t be used at the

same time. This method is generally used when many devices need to be connected to a single bus.

Since more than one device is connected to the same bus, all the other devices need to be in input mode

while one device is transmitting. The Main Controller that controllers of the SCServo actuators sets the

communication direction to input mode, and only when it is transmitting an Instruction Packet, it

changes the direction to output mode.

Connection to UART

To control the SCServo actuators, the main controller needs to convert its UART signals to the half

duplex type.
