1.10.7 USB port (rear side)
The USB-B port on the back side of the device is provided for communication with the de-
vice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 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.
1.10.8 Ethernet port (rear side)
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 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congurationpagefornetwork
parameters, as well as a 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). The
standard port for this device is 5025. 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 inter-
face or the USB interface and can, therefore, only be used alternatively to these. However,
monitoring is always available.
1.10.9 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 val-
ues, 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%.
