More Description

Universal Serial Bus (USB) has become the connectivity workhorse of today’s PCs, replacing the familiar serial port. However, many commercial and industrial devices still use the RS-485 interface. To connect these devices to modern PCs, you need a simple and reliable conversion solution. The 485USB9F-4W-LS offers RS-485 4-wire conversion in a space saving, USB port-powered package. Simply install the drivers and plug the converter into an available USB port on your computer or USB hub. The device will appear as an additional COM port in the Windows Device Manager which is fully compatible with your Windows applications. A one meter USB cable is included. Locked Serial Numbers Explained - The "locked serial number" format uses the same serial number (same COM port) that is associated with a given model type. If the converter is shared among several computers, like field service laptops, a locked serial number model lets you plug and play without having to worry about matching the two.
