Highlights for B&B Electronics ULINX 485USBTB-2W Data Transfer Adapter
  • Product Type:Data Transfer Adapter

Universal Serial Bus (USB) has become the connectivity workhorse of todays PCs, replacing the familiar serial ports. 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 485USBTB-2W and 485USBTB-4W 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. Select the 485USBTB-2W for RS-485 2-wire applications or the 485USBTB- 4W for RS-485 4-wire applications. Locked serial number versions are also available (see the installation notes in the driver section). 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.
