USB – RS 232 converter
1. INTRODUCTION The USB to Serial converter making the use of legacy peripherals and communication between PC and RS‐232 devices easily. It’s simple low cost‐effective solution ideal for various communication and automation applications. Full compliance with USB specification 1.1 and compatible with USB v2.0 ports. Supports the standard RS‐232 Serial (Com) interface and automatic handshaking mode. The USB to Serial converter connects RS‐232 serial devices to your USB providing a bridge connection with a DB‐9 female serial port connector on the end and USB port plug connector on the other side The USB‐RS232 converter board components meaning: - LED “READY” indicates that device is ready to use - B‐Type USB port connector - DB 9 female serial port connector “READY” RS232 driver

2. DEVICE OVERVIEW AND FEATURES • The USB‐RS232 converter interface consists of: • Tx (transmit) ⁞ Rx (receive) ‐ data signals. • RTS ⁞ CTS ⁞ DSR ⁞ DTR ⁞ DCD ⁞ RI ‐ control signals The UART supports RTS/CTS, DSR/DTR and X‐On/X‐Off handshaking. If the Virtual COM Port drivers are used, the data format and baud rate are set during serial port configuration on the PC. • 576 Byte receive buffer, 640 byte transmit buffer • Data bits: 5, 6, 7, 8 • Stop bits: 1, 1.5* 2 * ‐ 5 data bits only • Parity types: None, Even, Odd, Mark, Space • Baud rates: 9600, 14400, 19200, 38400, 56000, 115200 ( 7 / 8 data bits)

Be patient for few seconds until new one “pop‐up bubble” confirmation message will appear:
Figure 8. New hardware is ready to use
Congratulations! Virtual COM Port Driver is ready to use with USB‐RS232 converter. Please verify virtual com port driver installation
4.3 VERIFICATION OF VIRTUAL COM PORT DRIVER INSTALLATION Follow to the verification steps:
1. Click “My computer” icon on your Desktop or click menu “Start” ‐> select “Properties” from pop‐up menu 2. Select “Hardware” tab of “System properties” dialog 3. Click “Device manager” button 4. Expand tree of “Device manager” 5. Expand branch named “Ports (COM & LPT)” 6. In case of successful installation you’ll see node named “Silicon Labs CP210x USB to UART Bridge (COM3)” ***
