Telnet Protocol
As an alternative to remote control the instrument can use a simple telnet protocol (port
5025). Unlike using the VXI-11 protocol, no VISA installation is necessary on the
remote controller side. This protocol is sometimes also referred to as "socket communi-
cation" or "Raw Ethernet mode". To control the instrument, only a Telnet program is
required. The Telnet program is part of every operating system.
11.1.1.4 GPIB Interface (IEC 625/IEEE 418 Bus Interface)
To be able to control the instrument via the GPIB bus, the instrument and the controller
must be linked by a GPIB bus cable. A GPIB bus card, the card drivers and the pro-
gram libraries for the programming language used must be provided in the controller.
The controller must address the instrument with the GPIB bus address (see
Instrument Address"
Notes and Conditions
