<strong>USB</strong> <strong>to</strong> <strong>Serial</strong> <strong>UART</strong> <strong>TTL</strong> <strong>Converter</strong><br />
Enable two way serial communication from<br />
<strong>USB</strong> <strong>to</strong> your application required 3 or 5V<br />
levels. Typical application includes interfacing<br />
microcontroller application directly <strong>to</strong> <strong>USB</strong> port.<br />
The driver on PC provides Virtual <strong>Serial</strong> Port<br />
which is similar <strong>to</strong> RS232 port on PC so any<br />
existing COM port based software can connect<br />
easily.<br />
<strong>Features</strong><br />
• Direct connection <strong>to</strong> Microcontroller<br />
TX/RX pins<br />
• Virtual COM port on PC created connected over <strong>UART</strong><br />
• Simple <strong>to</strong> use & Plugs Directly <strong>to</strong> <strong>USB</strong> port<br />
• Can provide power external boards through <strong>USB</strong><br />
• Highly stable design based on <strong>USB</strong> 2.0 PIC microcontroller<br />
• Uses built in Windows OS <strong>USB</strong> Drivers<br />
• Works on all Operating Systems<br />

<strong>USB</strong> drivers for the following operating systems are available for download from our website:<br />
Windows XP, Windows7/8-32 Bit and 64 Bit<br />
Download <strong>USB</strong> Driver from below link, It has readme text file <strong>to</strong> help you with instructions <strong>to</strong> install.<br />

Plug in unit <strong>to</strong> PC’s <strong>USB</strong> port.<br />
You can open Start > Device and Printer menu <strong>to</strong> see the installed Port <strong>to</strong> which software can<br />
connect. A com port should also appear in Device Manager under Ports.<br />
Detected by PC as<br />
Virtual Com Port<br />
Normally your system au<strong>to</strong> assigns new COM port number.<br />
In future if you plug the unit <strong>to</strong> same <strong>USB</strong> port the COM port does not change.<br />
If you want <strong>to</strong> change its COM port number, then go <strong>to</strong> device manager, properties of particular com<br />
port and right click>advanced and select a COM port.<br />
