4.2.3.2 Installing the USB driver
The USB adapter and the driver CD are located inside the Interface Unit:
figure 4-3 USB and null modem cable connection
When the USB adapter is connected to a PC for the first time, the USB driver must
be installed. The Node C and Interface Unit must be switched on for the procedure.
To install the driver, proceed as follows:
• Connect the USB cable of the USB adapter to the USB port of the PC.
• Then, wait until the system (valid from Windows98ME) delivers the message that
a new USB device was found and asks for the driver.
• Put the CD into the CD-ROM drive of the PC and the system will ask how to
search for the driver.
• Select the automatic search (usually default), confirm, and wait while the system
searches for the driver.
• The successful installation will be informed by a message that the new hardware
was successfully installed.
• After confirming this message the CD can be taken out of the drive and put back
into the plastic cover inside the Interface Unit.
• Reboot the PC.
When the connection is made the next time, this procedure is no longer necessary.
