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.
16.1.1.3 GPIB Interface (IEC/IEEE 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 program
libraries for the programming language used must be provided in the controller. The con-
troller must address the instrument with the GPIB bus address.
Characteristics
●
Up to 15 instruments can be connected
●
The total cable length is restricted to a maximum of 15 m; the cable lenth between
two instruments should not exceed 2m.
●
A wired "OR"-connection is used if several instruments are connected in parallel.
GPIB Instrument Address
In order to operate the instrument via remote control, it must be addressed using the
GPIB address. The remote control address is factory-set to 20, but it can be changed in
the network environment settings. For remote control, addresses 0 through 30 are
allowed. The GPIB address is maintained after a reset of the instrument settings.

16.1.2 Starting and Stopping Remote Control
16.1.2.1 Starting a Remote Control Session
When you switch on the instrument, it is always in manual operation state ("local" state)
and can be operated via the front panel, the touch screen and external keyboard and/or
mouse.
► To start remote control:
● Send a command from the controller.
● VXI-11 protocol (LAN or USB interface): Use >R interface message.
While remote control is active, the instrument settings are optimized for maximum mea-
surement speed; the display is switched off. Operation via the front panel is disabled.
On the touch screen, two buttons appear in the upper left corner: "Local" and "View".
