1.4.2 Control of the R&S UPZ
There are three possibilities of controlling a R&S UPZ:
1.
Manually via an Audio Analyzer
2.
Via the IEC/IEEE bus
3.
Via the RS-232-C interface
The simplest way is to control the R&S UPZ via the Audio Analyzers R&S UPL,
R&S UPV or R&S UPP. Their firmware contains the complete control software for the
switcher so that all channel settings can be performed from the GUI.
Control via the IEC/IEEE bus is only possible by using an Audio Analyzer.
Depending on the device, a host PC can control the analyzer via IEC/IEEE-bus, LAN
or USB device, and the Audio Analyzer controls the R&S UPZ via the RS232 or USB
device. The required IEC/IEEE-bus commands are given in
Since the R&S UPZ has RS-232-C connectors, it can be directly controlled from a PC.

Remote Control via an External PC
1.4.3 Connecting the Control Lines
The R&S UPZ does not provide a user interface for controlling. To control an
R&S UPZ, either an Audio Analyzer (R&S UPL, R&S UPV or R&S UPP) or an external
host PC is required. The connection to the controlling device is either realized by
RS232 or USB.
1.4.4 Installing the USB Driver
How you have to install the USB driver for the R&S UPZ depends on whether the
Windows XP or Windows 7 operating system is installed on the R&S UPP/UPV. The
user interfaces of the two operating systems are considerably different, which is clearly
recognizable when you close the R&S UPP/UPV application and click the "Start" field
at the lower left with the mouse:
