Operating the device
11.2 Networking
The figures below depict networking examples for the digital
control of multiple devices in star-shaped (USB, RS232) or
bus-like (CAN, GPIB) configurations.
Limitations and technical specifications of the bus systems and
the interfaces apply.
With USB, up to 30 units can be controlled with one PC, ap-
propriate USB hubs with custom power supply assumed.This
basically applies to RS232, too. Differences lie in the handling
and the cable lengths.
With CAN, up to 30 power supplies per address segment can
be integrated into a new or existing CAN bus system. They
are addressed by the device node and the RID (see „8. Device
setup).
With GPIB, there is a limitation of max. 15 slave units on a
bus. Multiple GPIB masters can be installed in a PC in order to
increase the number of addressable units.

12. Miscellaneous
12.1 Accessories and options
Following accessories are available:
a) USB-to-Analogue interface UTA12
Galvanically isolated remote control via USB (on PC side) and
the device internal analogue interface.
b) Digital interface cards
Pluggable and retrofittable, digital interface cards for USB,
RS232, CAN, GPIB/IEEE (SCPI only), Profibus or Ethernet/
LAN (SCPI only) are available. Details about the interfaces can
be found in the interface cards manual.
Following options are available:
a) High Speed Ramping
Increased dynamics of the output voltage by reduced output
capacity. It must be pointed out, that other output related values,
like for example the ripple, also increase! This is a permanent
modification which is not switchable.
12.2 Firmware update
A firmware update of the device should only be done if the
device shows erroneous behaviour or if new features have
been implemented.
In order to update a device, it requires a certain digital interface
card, a new firmware file and a Windows software called „Update
tool", which is available as internet download.
These interfaces are qualified to be used for a firmware update:
• IF-U1 (USB)
• IF-R1 (RS232)
• IF-E1 (USB port)
• IF-PB1 (USB port)
In case none of the above interface types is at hand, the device
can not be updated. Please contact your dealer for a solution.
The update tool and the particular firmware file for your device
are obtainable from the website of the device manufacturer, or
are mailed upod request. The update too will guide the user
through the semi-automatic update process.
