IOLAN+ can be configured to take advantage of your
network's Domain Name Server (DNS). This is done from
the server in the Administration Menu by keying in the IP
address of your DNS in the Name server field. Fill in the
Domain name field as well.
If you need to attach IOLAN+ to a different network with a
new IP address, it is possible to reset it to factory default
condition using the following procedure:
1 Power on the unit
2 Wait 30 seconds
3 Hold down the RESET button for 15 seconds
4 Release the button
After this is done, the unit will start sending BOOTP request
packets.
This procedure is useful for factory defaulting units which
cannot be reached via TCP/IP. This includes reassigning a
programmed unit to a network to which the previously
assigned IP address does not belong.
Firmware can be downloaded across the network using tftp
protocol if the host machine and file name are set in the boot
host and boot file entries of the server menu. These entries
are checked at start up and if they have been configured, the
relevant file will be downloaded.
Note: tftp must be enabled on the releveant host as it is
disabled by default.
