Connect To The Usb Interface - TDT System 3 Installation Manual

42 System 3 Installation Guide

Connect to the USB Interface.

Important!: The TDT drivers must be installed before connecting the zBus
chassis to your PC (see page 19).
When using the USB interface, a UZ2 interface module is required for every
chassis which houses a programmable module such as the RX Multiprocessor
modules or the PA5 Programmable Attenuator. The UZ2 is installed in the back
bay of the chassis and should be connected to the PC USB port. If you have
multiple chassis housing programmable modules you will need an available USB
2.0 port on the host PC for each UZ2 in a multi-chassis system. We typically
recommend upgrading to an Optibit interface if a system requires more than
three chassis.
Note: The UZ2 is designed for USB 2.0 ports. Some systems might use the UZ1
and UB4 interfaces designed for USB 1.1 ports. Connections for 2.0 and 1.1
compatible devices are similar; however, each system should use EITHER the
UZ2 OR the UZ1/UB4 configuration. The two groups of devices should not be
combined. If you are unsure how your system should be configured, contact
TDT technical support staff for assistance. Also note that the UB4/UZ1 USB
interfaces should not be used with the high performance processors, such as
RX5, RX6, RX7 and RX8.
Connect the Interface to the Host PC.
To connect a device chassis (with UZ2 connector on the back of the chassis),
use the supplied A-to-B type USB cable to connect the UZ2 chassis to the USB
port on your computer.
