2.3 DIGITAL CONTROL VIA LAN [-1.2K MODELS ONLY]
Figure 2-1 shows all the ports available to the LAN interface. These port are described in Sec-
tion 9, LAN INTERFACE [-1.2K MODELS ONLY], and include:
• Port 80 - Web Interface. (See KLP User Manual for details on how to use the web inter-
face.) This port supports up to eight connections. For details as to how to access, oper-
ate and configure the unit using the web interface, refer to the KLP User Manual. In
addition, the web interface is compatible with \\LXI\instrument.xml and
\\LXI\instrument.xsd required by Version 1.2 of the LXI specification.
• Port 111 - SUNRPC (UDP Broadcast and TCP/IP). The SUNRPC port is used for discov-
ery when sent as a UDP broadcast message. The only command supported is the GET-
PORT. The ports that can be requested are detailed in the VXI specification and
repeated in the LXI specifications. The SUNRPC port can be also used with the TCP/IP
protocol. Again, the only command supported is the GETPORT. Port 111 is the method
(called the Discovery process) used by National Instruments and Agilent to find the
resource. KLP -1.2K Models support the discovery process implemented by Version 1.1
of the LXI Specification using this port and a VXI-11 protocol, as well as the XML proto-
col proposed by Version 1.2 of the LXI specification.
• Port 1024 - VXI-11. This port supports up to two connections. VXI-11 uses one standard
port (1024) and two assigned by the instrument when connections are opened. The
1024 port is open at all times to accept connection requests. The VXI-11 port requires
the use of a lock which prevents other VXI-11 connections from gaining access to the
instrument. This port is accessed using the VISA resource string ending in INST, e.g.:
TCIP0::192.168.1.100::INST
• Port 5024 - Telnet. This port supports up to two connections. the Telnet command pro-
vided with all windows operating systems can be run with the following command line
(use Start - Run) TELENET IPADDRESS PORT e.g.:
TELNET 192.168.0.100 5024
When the program is run, entering commands found in Appendix A and B of this Devel-
oper’s Guide allow the operation of the unit via the Telnet port.
