About the interface cards
4.1 RS232 cards IF-R1 and IF-R2
The RS3 interface card links the power supply with a
controlling unit (PC) via its serial port, also called COM port.
The settings of this serial connection have to be configured
on both ends to the same values. At the power supply this is
done in the setup menu. A 1:1 cable has to be used.
The card type 1 (IF-R1) features an additional serial interface
which is used to link multiple power supplies in order to build
the System Link Mode. More information about it in section
„6. The System Link Mode (only PSI9000)".
Never connect any of these ports to an Ethernet hub
or switch or Ethernet port of a PC!
4.1.1 Configuring the RS232 card
The interface card is configured in the setup menu.
It is absolutely necessary to choose and set a unique device
address, also called „device
linked unit. Only then a unit can be identified and controlled
correctly. This address is used to access a device.

Here you set the desired device node and you also get an

Each card has to be configured individually. You can now
setup the parameters:

Baud rate
= {9.6 kBd, 19. kBd, 38.4 kBd, 57.6 kBd}
The selected baud rate has to be determined in dependency
of the used cable length. At 15m a maximum of 9.6 kBd is
strongly recommended. 1kBd = 1000Bd.

4.2 USB cards IF-U1 and IF-U2

The USB interface works similiar to the RS3 card, but
it is more comfortable when connecting multiple units to a
PC via an USB hub. You can connect and control up to any
number (limited by the USB specs) of units with only one
PC and one USB port.
The card type 1 (IF-U1) features an additional serial interface
which is used to link multiple power supplies in order to build
the System Link Mode.

4.3 CAN cards IF-C1 and IF-U2

CAN Standard: V.0 part A
Cable length: depending on the baud rate
Specialty: Gateway to RS3 card or USB card
The communication over the CAN bus is specifically desi-
gned to suit the needs of test applications and systems, like
for instance in the automotive industry. A subsequent imple-
mentation into existing systems and the modification of a
related software application is possible and unproblematic.
The networking of CAN devices provides the advantage of
a faster communication and a fail-safe bus topology. The
driver chip on the CAN card can support up to 110
nodes (the term device node is used for addresses of CAN
units). The LabView VIs resp. the communication protocol
can handle up to 30 units per address segment (RID). Thus
it is theoretically possible to set up a bus system of up to 110
units, which will operate with at least 4 address segments.
The address segments are relocatable, so that the one or
multiple devices can be implemented into an existing CAN
bus without the need to reconfigure the whole system.
