The device can be addressed for control via the remote interface by means of a USB
connection and / or an Ethernet (TCP/UDP) connection. The USB interface appears as a so-
called virtual COM port on the PC and allows simple handling just like the usual serial
interface. The NRA internal TCP server allows connection to a client for exchanging data.
The IP address and the remote port of the TCP server must be known in order to set up the
Ethernet link. The IP address and port together with the communication protocol are also
called the socket interface.
The entire range of functions is available via the remote interface. You can set all the
measurement parameters and read out the measurement results cyclically.
Every command sent to the remote device generates a response. The time taken for the
response to come from the remote device depends greatly on the type of command.
Commands received in parallel (e.g. from USB and Ethernet) are processed sequentially in
the remote device.
One USB client is always connected to the USB host via the USB connection.
No provision has been made for multiple client connections to one remote device. The USB
connection is used primarily to configure the remote device.
You can directly connect a remote device to a computer using a crossover network cable.
Static IP addresses must be assigned to the client and the server for this, as the remote
device is not equipped with a DHCP server. In this instance, only one client can be
connected to the TCP server of the remote device.
