Alternatively to setting network parameters manually, DHCP can be activated by command and used by a DHCP
server in the network to dynamically assign them.
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.
3.5.3.3 Communication
Via TCP/IP and the port or via USB, communication to the device can be established in most of the common
programming languages.
Using the Ethernet or USB port, the device can either be controlled by commands from SCPI or ModBus protocol,
while automatically detecting the type of message.
There is no priority of any digital interface over another or the analog interface. Once remote control has been
activated via on of the interface, it will be in charge and the other interfaces could only be used for monitoring.
3.5.3.4 Programming
Programming details for the interfaces, the communication protocols etc. are to be found in the documentation
“Programming Guide ModBus & SCPI“ which is supplied on the included CD or which is available as download
from the manufacturer’s website.
