UZ2 USB 2.0 Interface
UZ2 USB 2.0 Interface
Overview
The USB 2.0 zBus Interface mounts in the rear bay of a zBus device chassis and
handles communication and data transfer between your computer and zBus mounted
programmable devices, such real-time processors or programmable attenuators. Most
nonprogrammable devices, such as speaker drivers or signal mixers, do not require
an interface. You will need a USB2.0 port available on the host PC for each UZ2
in a multi-chassis system. We recommend upgrading to an Optibit interface if a
system requires more than three chassis.
Note: If using the USB 2.0 interface on a 64-bit operating system, you must install
version 76 TDT drivers or greater.
Connecting the UZ2
The UZ2 connects to your computer with standard USB 2.0 A to B cables (provided
with each module). Interface drivers are bundled with the TDT Drivers and will be
installed when the device is connected to the host computer for the first time. The
UZ2 can be safely connected or unconnected while the computer is running.
Important! Wait ten seconds after devices have gone through the boot sequence or 30 seconds
after turning on devices (with the computer already running) before running
applications that use TDT devices. We also recommend using zBUSmon to verify the
logical order of devices before beginning any experiment. See “Boot Up Sequence”
below, for more information.
Sync
The Sync allows users to synchronize several modules that are mounted in different
device chassis. Each USB module has its own clock. Clocks on multiple USB
devices will drift relative to each other. The Sync line uses the clock from one USB
module, the master, to synchronize the clocks across all zBus device chassis.
To connect several zBus chassis, one module (the highest logical module) is
designated as the master and the other clocks are slaved to the master clock.
Connect the Sync Out of the master clock to the Sync In of the slave with a short
