1.9.5 USB port
TheUSB porton theback side ofthedevice isprovidedfor communicationwiththe deviceandfor rmware
updates. The included USB cable can be used to connect the device to a PC (USB 2.0, USB 3.0). The driver is
delivered on the included CD or is available as download and installs a virtual COM port. Details for remote control
can be found in external documentation, a general programming guide, on the web site of the manufacturer or on
the included CD.
The device can be addressed via the USB port using the international standard ModBus protocol.
1.9.6 Ethernet port
The Ethernet port on the back side of the device is provided for communication with the device in terms of remote
control or monitoring. The user basically has two options of access:
1. A website (HTTP, port 80) which is accessible in a standard browser under the IP or the host name (as long as
registeredinthelocalDNS)givenforthedevice.Thiswebsiteoffersacongurationpagefornetworkparameters,
as well as an input box for SCPI commands to control the device remotely by manually entering commands.
2. TCP/IP access via a freely selectable port (except 80 and other reserved ports).
ForcongurationoftheEthernetandsetupofTCP/IPconnection,refertosection3.5.3.
1.9.7 Analog interface
This 15 pole Sub-D socket on the back side of the device is provided for remote control of the device via analog
signals or switching conditions.
If remote control is in operation this analog interface can only be used alternately to the digital interface. However,
monitoring is always available.
1.9.8 Sense connector (remote sensing)
If the output voltage has to be dependant on the consumer location rather than the DC output of
the power supply, then the input “Sense” can be connected to the consumer where the DC con-
nection is made. This compensates, up to a certain limit, the voltage difference between the power
supply output and the consumer, which is caused by the high current through the load cables.
The maximum possible compensation is given in the technical data.
