See below the characteristics of the VISA resource strings for the corresponding inter-
face protocols. The highlighted characters are crucial.
HiSLIP
TCPIP::host address::hislip0[::INSTR]
●
hislip0 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 details of the HiSLIP protocol, refer to Chapter 10.1.2.2, "HiSLIP Protocol" ,
on page 281.
VXI-11
TCPIP::host address[::inst0][::INSTR]
●
[::inst0] LAN device name, indicates that the VXI-11 protocol is used (optional).
inst0 currently selects the VXI-11 protocol by default and can be omitted.
For details of the VXI-11 protocol, refer to . Chapter 10.1.2.3, "VXI-11 Protocol" ,
on page 282
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 associ-
ated protocol used.
The registered port for socket communication is port 5025.
See also Chapter 10.1.2.4, "Socket Communication" , on page 282.
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 rssgt100a100021 ; the valid resource string is:
TCPIP::rssgt100a100021::hislip0
(HiSLIP)
TCPIP::rssgt100a100021::inst0
(VXI-11)
●
A raw socket connection can be established using:
TCPIP::10.113.11.91::5025::SOCKET
10.1.2.2 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
