Description of the instrument (cont'd)
SUBNET mask
and GATEWAY If the result of the operation ' AND LOGICAL' between IP address of the
recipient of the message and the value of subnet mask is different from the
address of the recipient of the message, this message is sent to the
gateway which will be given the responsibility to forward it to destination.
The programming of the mask and the address of the gateway is possible
on the instrument, in the Advanced mode.
DHCP Protocol
This protocol is used to automatically assign an IP address to the
instrument when it connects up to the network.
A DHCP (Dynamic Host Configuration protocol) server must be accessible
on this network (contact your network administrator to make sure that this
server is present).
FTP protocol
A file can be transferred quickly between a PC and the instrument using FTP
(File Transfer Protocol).
To use it, open the browser on the PC and, in the URL field, type the IP
address of the instrument, preceded by " ftp: "
#
Example: ftp://192.168.3.1
The oscilloscope is an FTP server .
See §. Applications p. 176.
HTTP protocol
The instrument integrating the 'HTTP server' protocol functions like a WEB
server and can be accessed from a PC using a standard browser (EXPLORER,
NETSCAPE, FIREBOX …). You can then reach the most current adjustments
and visualize traces on your PC.
To use it, open the browser on the PC and, in the URL field, type the IP
address of the instrument, preceded by " http: "
#
Example: http://192.168.3.1
See §. Applications p. 174.
To be able to display the traces, you must install on your PC the Java Virtual
Machine JVM SUN 1.4.1 (or higher). This JVM can be downloaded from the
site http://java.sun.com
LPD protocol This protocol (Line Printer Daemon) is used by most of the printers
connected to an ETHERNET network, but also by the printing server units
which handle conversion between ETHERNET and CENTRONICS
(
#
Example: Jet Admin ) and UNIX and LINUX workstations.
An LPD server can also be installed on a PC (available as an option with
WINDOWS 2000 or XP).
In all cases, the instrument is an LPD client which has to be configured to
indicate to it the IP address of the LPD server (the workstation PC or
directly the printer) and the logical name of the printer managed by the
server.
See §. Applications p. 180.
