4. RS232 card IF-R1 / IF-R2
The RS232 interface card links the power supply with a
controlling unit (PC) via its serial port, also called COM
port. In case the PC does not feature one of these older
serial ports anymore, there are adapter cables available in
selected stores, which work via USB and generate a virtual
COM port on the PC.
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 can be found in
section „12. The System Link Mode (PSI9000 only)“.
Attention!
Never connect any of the RJ45 sockets of the IF-R1 card
to an Ethernet hub or switch or Ethernet port of a PC!
4.1 Configuring the RS232 card
The interface card is configured in the setup menu.
It not required to set the device address (node) here, since
RS232 is point-to-point. To simplify communication, the so-
called broadcast address 0 can be used to access the device
disregarding its particular address.
Activate the menu with
M
+ Communication +
Slot: { IF-… } depends on the equipped card
Only with PSI 9000 there is another slot available:
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 card(s) is/are currently installed. By selecting
the card with, for example,
Slot: IF-R1 +
you enter the configuration card‘s menu. If two are equipped
(PSI 9000), each card has to be configured individually. You
can now setup the parameters:
device node Default: 1
= {1..30} Choose one of up to 30 device nodes
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.
5. USB card IF-U1 / IF-U2
The USB interface works similiar to the RS232 card, but
it is more comfortable when connecting multiple units to a
PC, because nowaydays PC feature multiple USB ports.
Alternatively, devices with this USB card could be connected
via a USB hub.
The card IF-U1 features an additional RS485 interface which
is used to link multiple power supplies of series PSI 9000 in
order to build the System Link Mode. More information can
be found it in section „12. The System Link Mode (PSI9000
only)“.
Attention!
Never connect any of the RJ45 sockets of the IF-U1
card to an Ethernet hub or switch or Ethernet port of
a PC!
5.1 Configuring the USB card
The interface card is configured in the setup menu.
It not required to set the device address (node) here, since
USB is point-to-point. To simplify communication, the so-
called broadcast address 0 can be used to access the device
disregarding its particular address.
Activation of the menu is the same as with the RS232 card
in section 4.1.
Here you set the desired device node and you also get an
overview which cards are currently installed. A further con-
figuration of the USB card is not required.
Note
The USB driver installs a virtual COM port (VCP) on the
PC. This COM port has to be congured with certain pa-
rameters if used to communication with the device (see
„13. Programming“).
