RSIB Protocol
The R&S defined RSIB protocol uses the TCP/IP protocol for communication with the
instrument. Remote control over RSIB is done on a message level basis using the
SCPI command set of the instrument. The RSIB protocol allows you to control the
instrument for example via Visual C++- and Visual Basic programs, via the Windows
applications Word and Excel, as well as via National Instruments LabView, LabWind-
ows/CVI, Agilent VEE and others. The control applications run on an external computer
in the network.
RSIB Interface Functions
The library functions are adapted to the interface functions of National Instruments for
GPIB programming. The functions supported by the libraries are listed in the following
table.
Function Description
RSDLLibfind() Provides a handle for access to a device.
RSDLLibwrt() Sends a zero-terminated string to a device.
RSDLLilwrt() Sends a certain number of bytes to a device.
RSDLLibwrtf() Sends the contents of a file to a device.
RSDLLibrd() Reads data from a device into a string.
RSDLLilrd() Reads a certain number of bytes from a device.
RSDLLibrdf() Reads data from a device into a file.
RSDLLibtmo() Sets timeout for RSIB functions.
RSDLLibsre() Switches a device to the local or remote state.
RSDLLibloc() Temporarily switches a device to the local state.
RSDLLibeot() Enables/disables the END message for write operations.
RSDLLibrsp() Performs a serial poll and provides the status byte.
RSDLLibonl() Sets the device online/offline.
RSDLLTestSrq() Checks whether a device has generated an SRQ.
RSDLLWaitSrq() Waits until a device generates an SRQ.
RSDLLSwapBytes Swaps the byte sequence for binary numericdisplay (only required for
non-Intel platforms).
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.
