Introduction

Control Four Serial Devices from One USB Port!

Our USBS 1204 serial communications converters make it easy for newer computers with USB ports to communicate with older RS-232 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 1204 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 1204 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.

The USBS 1204-S offers surge protection for additional safety in tough industrial environments. We recommend this surge-protected model for all applications where speeds less than 461 kpbs and buffers no larger than 16 bytes are appropriate.
