Setting Configuration Values
When the Config
Preset Button is
Pressed
The recessed Config Preset button on the back panel of the Gateway is used
to reset the LAN/GPIB Gateway to its default configuration values (preset at
the factory). The
Config Preset button has two modes of operation.
n If you press the Config Preset button at the same time as you apply
power to the Gateway, all previous configuration information is
erased and all default configuration values are used.
This is helpful if you want to completely reconfigure the Gateway,
but you first need to set the Gateway to a known state (to a state
where the Gateway is using all of its default configuration values).
n If you press the Config Preset button after power is applied, previous
configuration information is not erased, but the Gateway temporarily
uses its default IP address. That is, only the IP address is reset to its
default value temporarily. Once you reboot or cycle the power again,
the Gateway will return to its actual IP address that was previously
set.
This is helpful if you want to interrogate the Gateway at a known
address in preparation for setting a new IP address for the Gateway.
However, all network connections to the Gateway, if any, are also
terminated without any cleanups.
NOTE
If you use the default IP address, you may need to explicitly tell your
networking software how to talk to the Gateway. This is because the
default IP address may appear to be on a different subnet. Use the
route command, as follows.
• On HP-UX client systems, as root:
route add host 192.0.0.192 your_system_name
Return
• On Windows 95/98/2000/Me/NT client systems:
route add 192.0.0.192 your_system_name
Enter
