12.4 Advanced remote control using fast socket
Fast settings
The socket interface can be utilized not only to transfer text messages, e.g., SCPI
commands but also to carry register based remote control messages. The latter mode
is called fast settings mode. The fast socket communication is based on the Ethernet
protocol which does not support routing. Therefore a controller PC can only control
devices within its own network segment using the fast socket method.
To use the advantage of the fast settings, the following prerequisites must be fulfilled:
●
On Windows operating systems, the fast socket driver must be installed.
●
The application program must be run with root/administrator rights.
●
The fast settings must be enabled with the function rssgs_useFastSettings
(see also Chapter 12.3.5, "Enabling fast settings", on page 190).
The instrument driver uses the fast settings method whenever possible, currently for
the parameters frequency, level, RF state, I/Q modulator state, IQ wideband state. In
all other cases, SCPI messages are sent.
12.4.1 Setting up a remote control connection via fast socket
Download the required archive and extract the files on a remote PC, as described in
Chapter 12.3.2, "Downloading the drivers", on page 187.
Windows operating systems
To set up a remote control connection via fast socket for Windows operating systems,
perform the following steps:
1. Connect the controller and the instrument: See Chapter 3.13.2, "Connecting a
remote PC via LAN", on page 30.
2. Install the protocol driver to the controller: See Chapter 12.4.2, "Installing the proto-
col driver", on page 192.
3. On the controller, start the driver by using one of the following:
a) Start the Windows console user interface as an administrator.
Excute the command net start SGMANDISPROT.
b) Use a program for opening the driver.
See, for example, the example file SgsDriverDemo.c.
4. Start the application with administrator rights.
5. Enable fast settings: See Chapter 12.4.3, "Enabling fast settings", on page 192.
