1.9.6

USB port

The USB-B port on the back side of the device is provided
for communication with the device and for firmware 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 USB stick 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 USB
stick.
The device can be addressed via the USB port either using the international standard ModBus protocol or by SCPI
language. The device recognises the message protocol used automatically.
If remote control is in operation the USB port has no priority over either the analog interface or the Ethernet interface
and can, therefore, only be used alternatively to these. However, monitoring is always available.
1.9.7

Ethernet port

The Ethernet port on the back side of the device (standard
version of device only) is provided for communication with
the device in terms of remote control or monitoring. The user
has basically two options of access:
1. A website (HTTP, port 80) which is accessible in a standard
browser under the IP or the host name given for the device.
This website offers to configuration page for network param-
eters, as well as a input box for SCPI commands.
2. TCP/IP access via a freely selectable port (except 80 and other reserved ports). The standard port for this device
is 5025, default IP is 192.168.0.2. Via TCP/IP and this port, communication to the device can be established in
most of the common programming languages.
Using the Ethernet port, the device can either be controlled by commands from SCPI or ModBus protocol, while
automatically detecting the type of message.
The network setup can be done manually or by DHCP. The transmission speed is set to "Auto negotiation" and
means it can use 10MBit/s or 100MBit/s. 1GB/s is not supported. Duplex mode is always full duplex.
If remote control is in operation the Ethernet port has no priority over either the analog interface or the USB interface
and can, therefore, only be used alternatively to these. However, monitoring is always available.
1.9.8

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.
The input voltage range of the set values and the output voltage range of the monitor values, as well as reference
voltage level can be switched in the settings menu of the device between 0-5 V and 0-10 V, in each case for 0-100%.
1.9.9

Sense connector (remote sensing)

During constant voltage operation (CV) and in case the adjusted output voltage has
to be held constant on the load and not on the power supply's DC output, remote
sensing can be used in order to compensate for the voltage drop on cables up to
a certain limit. The maximum possible compensation is given in the technical data.
