For details of the VXI-11 protocol, refer to . "VXI-11 Protocol" on page 50
Socket communication
TCPIP::host address::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 registered port for socket communication is port 5025.
See also "Socket Communication" on page 50.
Example:
●
Instrument has the IP address 10.113.11.91 ; the valid resource string using
VXI-11 protocol is:
TCPIP::10.113.11.91::INSTR
●
The DNS host name is rssgu100a100021 ; the valid resource string is:
TCPIP::rssgu100a100021::hislip0
(HiSLIP)
TCPIP::rssgu100a100021::inst0
(VXI-11)
●
A raw socket connection can be established using:
TCPIP::10.113.11.91::5025::SOCKET
HiSLIP Protocol
The HiSLIP ( Hi gh S peed L AN I nstrument P rotocol) is the successor protocol for
VXI-11 for TCP-based instruments specified by the IVI foundation. The protocol
uses two TCP sockets for a single connection - one for fast data transfer, the
other for non-sequential control commands (e.g.
Device Clear
or
SRQ
).
HiSLIP has the following characteristics:
●
High performance as with raw socket network connections
●
Compatible IEEE 488.2 support for Message Exchange Protocol, Device
Clear, Serial Poll, Remote/Local, Trigger, and Service Request
●
Uses a single IANA registered port (4880), which simplifies the configuration
of firewalls
●
Supports simultaneous access of multiple users by providing versatile locking
mechanisms
