The IP address or hostname is used by the programs to identify and control the
sensor. While the hostname is determined by settings in the sensor, the IP
address is assigned by a DHCP server when the sensor requests one. Alterna-
tively the IP address is determined with a procedure called Zeroconf.
You can also assign a LAN device name which defines the protocol characteris-
tics of the connection. See the description of the VISA resource string below for
the corresponding interface protocols. The string of the
LAN device name is
emphasized in italics.
VXI-11
TCPIP::<IP address or hostname> [::inst0] [::INSTR]
●
inst0 is the LAN device name, indicating that the VXI-11 protocol is used
(optional)
inst0 currently selects the VXI-11 protocol by default and can be omitted.
For further details, see Chapter 7.2.2, "VXI-11 Protocol" , on page 55.
HiSLIP
TCPIP::<IP address or hostname> ::hislip0 [::INSTR]
●
hislip0 is the HiSLIP device name, designates that the interface protocol
HiSLIP is used (mandatory)
hislip0 is composed of [::HiSLIP device name[,HiSLIP port]] and must be
assigned.
For further details, see Chapter 7.2.3, "HiSLIP Protocol" , on page 55 .
Socket communication
TCPIP::<IP address or hostname> ::port::SOCKET
●
port determines the used port number
●
SOCKET indicates the raw network socket resource class
Socket communication requires the specification of the port (commonly referred
to as port number) and of "SOCKET" to complete the VISA resource string with
the associated protocol used.
The default port for socket communication is port 5025.
For further details, see Chapter 7.2.4, "Socket Communication" , on page 56.
