Configuring the IPL for network use via the ARP command
The ARP (address resolution protocol) command tells your computer to associate
the IPL 250’s MAC (media access control) address with the assigned IP address.
You must then use the ping utility to access the controller, at which point the
controller’s IP address is reconfigured.
Use ARP to configure the IP address as follows:
1. Obtain a valid IP address for the IPL 250 from your network administrator.
2. Obtain the IPL’s MAC address (UID #) from the label on its rear panel. The
MAC address should have this format: 00-05-A6-xx-xx-xx.
3. If the IPL has never been configured and is still set for factory defaults, go to
step 4. If not, perform a Mode 4 system reset. For detailed information on
reset modes, see “Resetting the Unit” in chapter 2, “Installation”.
C The IPL must be configured with the factory default IP address
(192.168.254.254) before the ARP command is executed, as described below.
4. At the PC, access the MS-DOS command prompt, then enter the arp –s
command. Type in the desired new IP address for the unit and the unit’s
MAC address. For example:
arp –s 10.13.197.7 00-05-A6-03-69-B0
N The MAC address is listed on the rear panel.
After the arp -s command is issued, the controller changes to the new
address and starts responding to the ping requests, as described in the next
step.
5. Execute a ping command by entering “ping” followed by a space and the new
IP address at the command prompt. For example:
ping 10.13.197.7
You must ping the IPL 250 in order for the IP address change to take place.
The response should show the new IP address, as shown in the following
picture.
