2.4 Other USB Devices You Might Need
• Conventional devices without a USB interface
require a USB converter—for example, if your PC
does not have a USB interface, you’ll need the
USB Card (PCI)(part number IC136C).
• To attach more than one device, you will also need
a USB Hub. Choose the USB Director (4- or 7-Port
Hub) (part number IC134A or IC137A) to
connect 4 or 7 USB peripherals.
• Connect 4 high-speed serial devices to one USB
port via the USB Director (USB
→
RS-232 Hub)
(part number IC135A).
