Universal Serial Bus (USB) has become the connectivity workhorse of today's PCs replacing the familiar serial ports. However many commercial and industrial devices still use the TTL interface. To connect these devices to modern PCs you need a simple and reliable conversion solution. The TTL5USB9M and TTL3USB9M offer this solution in a space saving USB Port powered package. Simply plug the converter into an available USB port on your computer or USB hub and install the drivers supplied on CD ROM. The device will show up as an additional COM port in the Windows Device Manager which is fully compatible with your Windows applications. Choose the TTL5USB9M for 5V TTL and the TTL3USB9M for 3.3V TTL. Locked serial number versions are also available (see the driver installation notes at the end of this document). A one meter USB cable is included. Remember when it comes to USB to Serial Conversion B&B Electronics Ulinx™ brand is your number one choice.
