11.2 Networking
Figure 7 and 8 depict networking examples for the digital control
of multiple devices in star-shaped (USB, RS232) or bus-like (CAN,
GPIB)conguration.
Limitationsandtechnicalspecicationsofthebussystemsand
the interfaces apply.
With USB up to 30 units can be controlled with one PC, appropri-
ate 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 units on one bus, con-
trolled by a GPIB master. Multiple GPIB masters can be installed
in a PC in order to increase the number of addressable units.
11.3 Accessories and options
Note: Details about options and accessories are avaible in se-
perate user guides.

b) Digital interface cards
Pluggableandretrottable,digitalinterfacecardsforUSB,RS232,
CAN, GPIB/IEEE (SCPI only) or Ethernet/LAN (SCPI via VXI11)
are available.
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
also increase!
Note: this is a permanent modication which is not switchable.
