Step 1 - Setting up a temporary IP address

This step is only necessary if the network used to configure the unit can not access the
default IP address (

192.168.24.53

). In this case the unit must be switched into the

Configuration Mode which allows setting up a temporary IP address accessible from the
current network. The temporary IP address should be selected such that it is:

1) accessible on the network;

2) is not already used by any other device on the same network.

First, run ARP on the computer that is connected to the same network with the
following command line:

arp -s

The MAC address is

08-00-56-xx-yy-zz

, where xx-yy-zz are the last 6 digits of the

board's serial number. If your unit is in the enclosure, please use the serial number
labeled as the “Board SN”.

For example, for the unit with the board's serial number 526501 use the following
command

arp -s 10.135.1.61 08-00-56-52-65-01

In Windows either navigate to Start/Run and type the command line in the “Open” box,
or start a Command Prompt window and type the command line followed by Enter.

In Linux type the command line in the terminal window at the shell prompt followed by
Enter. Please use colons (:) instead of dashes (-) in MAC address.

Note: it is recommended to use a temporary IP address that is different from the target
permanent address to be assigned to the unit.

Now switch the 2453 into the Configuration Mode by pressing the configuration button.
The red LED starts blinking.

Note: you need to wait 15 seconds after the 2453 is powered up before the board is able
to switch to Configuration Mode.

Once the 2453 receives a network packet addressed to it, the temporary IP address will
be in effect. To send a packet either ping the board or connect to it with a browser.
Using an IP address from the example, either run

ping 10.135.1.61

or type

http://10.135.1.61

into the address bar of your browser

on the computer connected to the same network as the 2453. Once the temporary
address is enabled the red LED will blink fast several times and go off.

Once the unit is accessible using a temporary IP address, the standard Web page
procedure (Step 2) can be used to set up the desired permanent IP address and other
settings.
