2 Start-up User Manual PROFview XL
2.3.2 Mains connection
The desktop power adapter included in the scope of supply possesses a wide-range input for connection to
mains voltages from 100 V to 240 V 50/60 Hz; the output is a d.c. voltage of 24 V. The cable of the desktop
power adapter is inserted into the PROFview XL using the external voltage connector to DIN 45323. Once the
mains power cable is inserted into the desk power adapter and the mains power plug into the mains socket-
outlet, the PBT is ready for operation. This is indicated by the "Power On" LED on the device.
2.3.3 PROFIBUS connection
Various adapter cables for connecting the PROFview XL to a PROFIBUS plant are included in the scope of
supply. These enable the device to be connected both via SUB-D 9 or M12 connector.
2.3.4 Connecting the PROFIBUS Tester to a storage oscilloscope
To display the signal quality of individual PROFIBUS stations on a DSO, the PBT generates a station-related
trigger pulse. Thus, it is merely necessary to connect the BNC socket of the device to the external trigger in-
put of the oscilloscope.
The adapter board included in the scope of supply can be connected to the second SUB-D 9 socket, for sim-
ple sampling of the signals from the data lines A and B and the shield potential with the oscilloscope probes.
To sample the data transfer signal, a differential probe is recommended (signal line A against signal line B). If
two simple probes are used (A against shield and B against shield), the storage oscilloscope must provide
mathematics functions to be able to generate the difference (B minus A).
2.3.5 Connecting the device to the PC
The PBT is connected to a PC or notebook via the "hot-plug-&-play-capable USB port. Before you connect
the device to a PC or notebook, it is recommended to install the supplied software, as it includes the neces-
sary USB driver (see Section 4.2 "Installing the software").
2.4 Prevention of accidents
When operating this test device, it is imperative to observe the general accident prevention regulations for the
use of measuring instruments. The device must only be used in dry rooms.
