3-3 IPL 250 • Software-based Configuration and Control
Communicating with the IPL
To communicate with the IPL 250, you must power on the IPL and the PC you will
use to configure it, and connect the two devices for IP (network) communication.
• Power:
see chapter 2 for wiring instructions. It is best to power the IPL using the
12 VDC external power supply that is shipped with the unit.
• Communication: to connect the IPL to a network or to connect it directly to
the PC using a serial cable, see page 2-6 or page 2-7 of this manual for wiring
instructions. See “Configuring the IPL for Network Communication,“ below to
set the unit up to talk with the PC.
Configuring the IPL for Network Communication
To function together, both the PC and the IPL 250 must be configured correctly. The
PC must be network-capable with the proper protocols, and the IPL must be set up
so it can be connected to a LAN or other network.
When you power on the IPL for the first time, you have a choice of several ways to
set up the IP address:
• Use the Global Configurator software via the LAN connector.
• Use the ARP (address resolution protocol) command via the LAN connector.
• Use a Web browser via the LAN connector.
• Use SIS commands via Telnet and the LAN connector.
If you use a Web browser or Telnet the first time you connect a PC to an IPL via IP,
you may need to temporarily change the PC’s IP settings in order to communicate
with the controller. See “Setting up the PC for IP communication with an IPL” later
in this chapter. Then you must change the controller’s default settings (IP address,
subnet mask, and [optional] administrator name and password) in order to use the
unit on an intranet (LAN) or on the Internet. After you have set up the IPL 250 for
network communication, you can reset the PC to its original network configuration.
IPL 250’s LAN port defaults:
• IPL’s IP address: 192.168.254.254
• Gateway’s IP address: 0.0.0.0
• Subnet mask: 255.255.0.0
• DHCP: off
• Link speed and duplex level: autodetected
N Both the computer and the IPL must be connected to the same subnet on a LAN
(using a straight-through cable). Alternatively, you can use a crossover Ethernet
cable to connect the controller directly to your computer’s Ethernet card.
The following instructions assume that you have already connected the PC to the
IPL’s LAN port and powered on the controller and the PC.
Configuring the IPL for network use via Global Configurator
You can configure the controller’s IP address via an IP/Ethernet connection using
the Extron Global Configurator (GC) software. Read the Global Configurator help
file for basic information on using Global Configurator software and setting up a
project. Also read the IPL 250 Setup Guide for step-by-step instructions of how to
use GC to set up the IPL’s IP address.
