USB to TTL Miniature Converters

TTL5USB9M, TTL5USB9M-LS,

TTL3USB9M, TTL3USB9M-LS

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 install the drivers supplied on CD ROM and plug the converter into an

available USB port on your computer or USB hub. 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. A

one meter USB cable is included.

Locked Serial Numbers Explained

We configure our single-port USB to serial converters in two ways. In standard

format, each product has a unique serial number. “Locked serial” format uses the

same serial number that is associated with a model type.

If your converter will always be used with the same computer, the standard

serialized model is all you need. If the converter is shared among several

computers, like field service laptops, the locked serial number model lets you

plug and play without having to worry about matching the two.
