Establishing Communications For Setup; Option 1: Assign A Temporary Ip Address To The Webrelay-10 Plus - ControlByWeb WEBRelay-10+ User Manual

2.3 Establishing Communications for Setup

The WebRelay-10 Plus™ is set up using a web browser. The first task is to establish communications between a
computer and the WebRelay-10 Plus™ so that the browser-based configuration can begin. To do this, the com-
puter and the WebRelay-10 Plus™ must be physically connected to the same network and both must have IP
addresses on the same network. There are two ways to set up the computer and the WebRelay-10 Plus™ so that
they are on the same network. The first (Option 1) is to change the IP address of the WebRelay-10 Plus™ to an
address that is on the same network as the computer. The second (Option 2) is to change the IP address of the
computer to an address that is on the same network that the WebRelay-10 Plus™ is set to by default.

2.3.1 Option 1: Assign a temporary IP address to the WebRelay-10 Plus™

This option is used to TEMPORARILY assign an IP address to the WebRelay-10 Plus™ without the need to
change the IP address of the configuration computer. Note that the WebRelay-10 Plus™ will only use this IP
address as long as power is maintained. Once power is lost and restored, the WebRelay-10 Plus™ will use the IP
address assigned in the setup page and not the temporary address assigned here. This means that once commu-
nications are established, the desired IP address should be entered into the Network setup tab using the browser.
To assign the temporary IP address...
1. Make sure the WebRelay-10 Plus™ and the configuration computer are connected to the same network. This
will not work through routers or gateways.
2. Assign the address as follows:
Windows:
Open a Command Prompt (select START, then RUN, then type "cmd").
Note: For Vista, the Command Prompt should be run as administrator (select Start, then type "cmd" and right click
on "cmd" and select "Run as administrator").
Type:
arp -s {new IP address} {serial number of the WebRelay-10 Plus™ }
Note: IP address format is xxx.xxx.xxx.xxx
Serial number format is ss-ss-ss-ss-ss-ss
For example, to set the WebRelay-10 Plus™ (with serial number 00-0C-C8-01-00-01 ) to 10.10.10.40
the following command would be used:
arp -s 10.10.10.40 00-0c-c8-01-00-01
Next, type:
ping -l 102 {new IP address}
For example, if the new IP address is 10.10.10.40, the following command would be used:
ping -l 102 10.10.10.40
Linux/Unix:
Open a terminal, change to root user (su -, then enter root password).
