Remote Control
Now that you have successfully installed the NI-VISA driv-
ers, you can switch your ¸HMC8012 power supply
to the USB-TMC interface. Select the SETUP menu and
choose INTERFACE.

Use the soft key to select "USB TMC". The main view will
now display "TMC" as selected interface type.

Finally, use a USB interface cable (type A – B) to connect
the power supply with your Windows PC. On the first use,
the operating system issues the following message:
"Found New Hardware". Once the installation has been
successfully completed, the following message will be
displayed: "Device Setup" - "USB Test and Measurement
Device (IVI), ready to use".

Once you open the Windows Device Manager, the follow-
ing entry will be displayed: "USB Test and Measurement
Devices --> USB Test and Measurement Device (IVI)".

Ethernet

For the direct connection with a host (PC) or indirect con-
nection over a SWITCH, a doubly protected network cable
(e.g. CAT.5, CAT.5e, CAT.5+, CAT.6 or CAT.7) is required,
equipped with an Ethernet plug type the RJ-45 at each
end. Either an uncrossed or a crossed network cable (cross
over cable) can be used.
9.3.1 IP networks (IP – Internet protocol)
In order that two or several network elements (e.g. measu-
ring instruments, host/PC's, ...) can communicate over a
network with one another, some fundamental connections
have to be considered, so that data communication is error
free and unimpaired. For each element in a network an
IP address has to be assigned, so that they can exchange
data among themselves. IP addresses are represented
(with the IP version 4) as four decimal numbers separated
by points (e.g. 192.168.15.1). Each decimal number is
represented by a binary number of 8 bits. IP addresses
are divided into public and private address ranges. Public
IP addresses will be able to route by the Internet and an
Internet service Provider (ISP) can to be made available.
Public IP addresses can be reached directly over the Inter-
net to directly exchange internet data. Private IP addresses
are not routed by the Internet and are reserved for private
networks. Network elements with private IP addresses
cannot be reached directly over the Internet so no data can
be directly exchanged over the Internet. To allow network
elements with a private IP address to exchange data over
the Internet, they require a router for IP address conversion
(English NAT; Network address translation), before con-
nection to the Internet. The attached elements can then
data exchange over this router, which possesses a private
IP address (LAN IP address) and also a public IP address
(WAN IP address), via the Internet.
If network elements exchange data only over a local net-
work (without connection with the Internet), appropriate
use private IP addresses. Select in addition e.g. a private IP
address for the instrument and a private IP address for the
host (PC), with which you would like to control the instru-
ment. If you might connect your private network with the
