5.1.1.1 VXI-11 Protocol
The VXI-11 standard is based on the ONC RPC (Open Network Computing
Remote Procedure Call) protocol which in turn relies on TCP/IP as the network/
transport layer. The TCP/IP network protocol and the associated network services
are preconfigured. TCP/IP ensures connection-oriented communication, where
the order of the exchanged messages is adhered to and interrupted links are
identified. With this protocol, messages cannot be lost.
5.1.1.2 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
●
Usable for IPv6 or IPv4 networks
