Chapter 2 Driver Installation
This chapter includes information about installing the UPort 1400/1600 USB-to-Serial Hub. We
present the installation procedure for Windows 2000. The procedures for Windows XP/2003 (32
bit) and Windows XP/2003 (64 bit) are essentially the same as that for Windows 2000.
We recommend installing the UPort 1400/1600 driver first, before connecting the UPort
1400/1600 USB-to-Serial Hub to your computer’s USB port.
The following topics are covered in this chapter:
 USB Usage Limitations for UPort
 Installing the Driver
 Connecting the Hardware
¾ Connecting to the External Power Adaptor
¾ Connecting to a Serial Device
¾ LED Indicators
 Installing the Driver for the Server
 Installing the Driver for the Ports
 Configuring the Ports
 Uninstalling UPort
 Uninstalling the Driver
WARNING
If your host PC uses an nVIDIA nForce 4 processor and you find that your host PC is not
receiving the correct data, you should enter the PC’s BIOS configuration utility and disable USB
2.0. This will cause your host PC to use the USB 1.1 specification, which should prevent the data
transmission problem from recurring.
