Introduction

Control Two Serial Devices from One USB Port!

Our USBS 2401 Serial Communications Converter make it easy for newer computers with USB ports to communicate with older RS-232, RS-422 and RS-485 serial-port devices. Because USB data speeds are so high, by using our USBH series hubs to attach more than one USBS unit per USB port, one downstream USB port can support up to 16 serial ports.

USBS 2401 converters allow you to establish serial communications without ever opening up you computer case. They also eliminate the need for such system resources as I/O ports and IRQs to support serial communications. The USB converters require a computer system that supports v1.1 USB, both in hardware and operating system, and they come with drivers for Windows®: 98/2000/XP; Windows NT4 drivers free upon request.

The series automatically configure themselves. After you install the included software, your computer automatically recognizes all models and configures them. You can add or delete any number of USBS converters without ever reconfiguring your system or fussing with jumpers and DIP switches!

Our USBS 2401 models are powered from the USB cable, so you need no additional power supplies. However, USBS models should normally be connected to a self-powered hub that is capable of supplying 500mA of current per port. 

USBS series 2000 converters are recommended for applications where data rates in excess of 920 kpbs are required, and where buffer sizes of 128 bytes (TX) and 384 bytes (RX) help to prevent lost data. Optical isolation on our one-port USBS 2401-I also guards against ground loops and other stray voltages.
