10.4 Advanced Remote Control Using Fast Socket

Fast settings
The socket interface can be utilized not only to transfer text messages e.g. SCPI com-
mands 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 pro-
tocol which does not support routing. Therefore a controller PC can only control devi-
ces within its own network segment using the fast socket method.
