5.4 Connecting to Computer through UART

5.4.1 Connecting Shield-Servo to Computer

Another concern in controlling Servo motor using a computer is the hard work needed to get

started. However, with Shield-Servo, interfacing with a computer is as easy as 1 2 3. Normally,

user will need to develop a RS232 level shifter for communication to serial port. This

generates extra work. Furthermore, laptop and computer nowadays have phase-out the serial port

and replaced it with USB. With these reasons, an USB to UART converter, UC00A/UC00C,

have been developed by Cytron Technologies. Simply plug UC00A/UC00C to Shield-Servo and

USB port of computer (PC or Laptop), install the driver (for the first time only) and it will

create a virtual COM port in your computer and is ready to communicate with Shield-Servo. Only

power source for Servo motor is needed if using PC.

User may refer to UC00A/UC00C User’s Manual for hardware and software installation. So, no

extra work is needed to control Shield-Servo using a computer. And, of cause, you may connect

more than one UC00A/UC00B/UC00C to your computer and control more than one Shield-Servo

at the same time.

A Graphical User’s Interface (GUI) comes together with the source code is provided for user to

implement Servo motor control using a computer.

a. To begin, connect VM and GND to power source. Please refer to chapter 3, Product

Specification and Limitations, for details.

b. Connect Servo motor to a Shield-Servo.

c. To interface with a computer, simply connect UC00A/UC00C 6-pin connector to

d. Shield-Servo and the USB end to PC. Please note that the

TX and RX pins between Shield-Servo and UC00A/UC00C are cross-connected.

e. Please refer to documents named “USB Driver Installation Guide” included in

UC00A/UC00C package for driver installation.

f. After plugged in UC00A/UC00C to computer and installed the driver, user is ready to test

the functionality of Shield-Servo using Shield-Servo GUI.
