LAN Option
The FOCUS LAN is easily recognizable by the presence on the GC rear panel of a
RJ45 connector, 2 LEDs for LAN activity and a reset button.
The FOCUS LAN sampler is shipped with a default IP address, which may not
match the LAN needs of the sites where the sampler must be installed.
To change the default values, contact your LAN administrator and ask for the IP
address to be assigned, the netmask, and eventually the port. The IP address and
communication port may be reset to default value by pushing the reset button,
accessible from the rear panel of the FOCUS GC, for at least 5 seconds.
CAUTION The reset button is accessible introducing a little screwdriver into the relevant
passing hole.
To set the IP address and the LAN communication port, follow the instructions
reported in Chapter 14
