IOLAN
+
- User and Administration Guide
Domain Name
Server (DNS)
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.
Reassigning
IOLAN+ to a
New Network
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.
Updating IOLAN+
Firmware
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.
