Features:
Create a virtual serial port via USB for serial communication. Supports TTL or CMOS Level (5V or 3.3V), RS-232C Level (±12V) signal. TTL or CMOS Level (5V or 3.3V) signals are output (direct use with MCU, logic) with 5045-4 connectors and RS-232C Level (±12V) signals are available with 5267-3 connectors and 9-pin D-SUB for serial communication control signals (with loop back resistance removed). Basic settings are communicated with loop back resistance and RXD, TXD, TXD, GND 3 pins only. Can be used with RI/DTR/CTS/RTS/DSR/DCD when using handshake modes. USB 5V power supply (when using UART 4-pin connector).
