4.1 RS232 card IF-R1
The RS232 interface card IF-R1 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 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 ConguringtheIF-R1
The interface card is configured in the setup menu.
It is absolutely necessary to choose and set a unique device
address, also called „device node“, for every connected or
linked unit. Only then a unit can be identified and controlled
correctly. This address is used to access a device.
Activate the menu with
M
+Communication+
 device node Default: 1
= {1..30} Choose one of up to 30 device nodes
Slot A : { IF-… } depends on the equipped card
Slot B : { IF-… } depends on the equipped card
Here you set the desired device node and you also get an
overview which cards are currently installed. By selecting
a card with
Slot {A|B}: IF-R1 +
you enter the configuration menu for that particular card.
Each card has to be configured individually. You can now
setup the parameters:
 Baud rate Default: 57.6 kBd
= {9.6 kBd, 19.2 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 card IF-U1
The USB interface IF-U1 works similiar to the RS232 card,
but it is more comfortable when connecting multiple units to
a PC via an USB hub. You can connect and control up to 30
units with only one PC and one USB port.
The IF-U1 features an additional serial interface which is
used to link multiple power supplies in order to build the
System Link Mode.
Never connect any of these ports to an Ethernet hub
or switch or Ethernet port of a PC!
More information about it in section „4.5 System Link
Mode“.

4.3 CAN card IF-C1
CAN Standard: V2.0 part A
Cable length: depending on the baud rate
Specialty: Gateway to RS232 cards or USB cards
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 device
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.
