System 3 Installation Guide 45
This program allows you to test the USB connection from the PC to the System
3 hardware. The hardware diagram displays all zBus chassis and programmable
devices, such as the RP2.1, RX6 and PA5. The hardware diagram will not show
most non-programmable devices, such as the HB7 or SM5, however non-
programmable devices that require a connection to the PC (for example
RA8GA, HTI3) will appear as an empty zBus chassis.
The programmable devices are given a logical index starting with 1 so that
multiple devices of the same type can be distinguished in software.
Important!: The device indices are dependent on the order in which the
devices were powered on and recognized by the PC. Software applications
connect to the devices by name and index value. If you have multiple devices of
the same type it is very important that you power on the devices in the same
order every time so that the device indices will be consistent in software. The
number of the zBus chassis, displayed to the right of the chassis in the diagram,
reflects the order in which the USB devices were powered on.
The microcode version of all real-time processors (RXn, RPx and so forth) is
displayed in parentheses to the right of the part number in the diagram. They
must match the current version of TDT Drivers installed on the PC. If you
installed the drivers that came with your system, then your devices were
preprogrammed with the correct microcode. If you update your TDT Drivers in
the future you must also manually update the microcode for each of your real-
time processors. See Updating Your System at the end of this guide for more
information.
When the Show Version check box is selected, the microcode version of the
interface and of each programmable device is displayed. Note that the USB
microcode version number (v22) is fixed and cannot be changed by the user.
The microcode on the PA5 programmable attenuators (v30) is also fixed.
A Transfer Test can be used to test data transfer both to and from the PC.
To perform a transfer test:
 Click the Transfer Test button in zBUSmon.
