sure that the RS-232 selection as the interface is indicated
by a check mark. you can select the interface parameters
under Settings.

USB

All statements about the USB interface also apply to the stan-
dard interface card HO720 and the optional HO730. The USB
drivers are available for both 32 bit and 64 bit Windows versions.
The USB interface must be selected in the menu of the
power supply and requires no further action. If it is con-
nected to a PC for the first time, Windows ™ requires the
installation of a driver. The driver is included on the sup-
plied CD or it can be downloaded for the HO720 / HO730
at www.hameg.com. It is possible to connect via regular
USB connection or via virtual COM Port (VCP). Information
about driver installation is included in the HO720 / HO730
manual.
For a connection via virtual COM Port (VCP) it is required to
select the USB interface in the HMP.

Ethernet (Option HO730)

In addition to the USB interface, the optional interface card
HO730 includes an Ethernet interface. The required
parameters are selected in the power supply once ETHER-
NET has been selected as interface. you can specify all
parameters and assign a fixed IP address. You can also
assign a dynamic IP address with the activated DHCP
function. Please contact your IT management to configure
the settings properly.
If DHCP is used and the system cannot assign an IP address to
the HMP (for instance, if no Ethernet cable is connected or the
network does not support DHCP), it may take up to three minutes
until a timeout allows the interface to be configured again.

If the device has an IP address, it can be accessed via web
browser at this IP since the HO730 includes an integrated
web server. Enter the IP address in the location bar on your
browser (http//xxx.xxx.xxx.xx). This opens a window that
includes the instrument name and type, serial number and
interfaces with technical information and configured par-
ameters. To the left, you can use the link SCREEN DATA to
transfer a screenshot of the HMP (right-click to copy to the
clipboard for further use). The link SCPI DEVICE CONTROL
opens a site with a console to send remote SCPI com-
mands to the power supply. For further information, con-
sult the HO730 manual at www.hameg.com.
In general, the HO730 works with a RAW-Socket communication
to control the instrument and to retrieve the measuring values.
Therefore, a TMC protocol or a similar protocol will not be used.
6 .4 IEEE 488 .2 / GPIB (Option HO740)
The optional interface card HO740 includes a IEEE488.2 in-
terface. The required parameters are selected in the power
supply once IEEE 488 has been selected as interface. For
further information, consult the HO740 manual at www.
hameg.com.
