Configuring a PL1000E Communication Module to Work on a Non-DHCP network

Perform the following steps in order to configure a PL1000E Communication Module to work on a network that does not have Dynamic Host Configuration Protocol(DHCP).

Note: If a PC is to be connected directly to the PL1000E via a crossover ethernet cable, then leave the IP configuration set to the default settings. Go to the “Configuring a Stand – Alone Windows PC to Access the PL1000E Communication Module” section.

For more information on the default settings, see the section on Internet Protocol Configuration.

  1. Connect a computer with Caterpillar Electronic Technician (Cat ET) or Caterpillar Communications Tool Kit to a PL1000E Communication ECM either by using a “Comm Adapter II” or the “ECA Service Port (serial port 3)” on the PL1000E.
  1. Start Cat ET and wait for it to connect to the PL1000E.
  1. Once Cat ET is started and the selected device is the PL1000E, click on the “Configuration Screen” or press the F5 key.

  1. Enter the four parts of the IP address in the four fields according to the information that is provided by the network administrator. Click “OK”.

    Note: If a PC is to be connected directly to the PL1000E via a crossover ethernet cable, then leave the IP configuration set to the default settings.

  1. Click “Yes” in order to program the PL1000E.
  1. In order to make the PL1000E changes effective, turn the key switch to the OFF position, then turn the key switch back to the ON position. The PL1000E is ready for direct connect use.

Configuring a Stand – Alone Windows PC to Access the PL1000E Communication Module

Note: The PC must be equipped with a wired Ethernet adapter. If the PC is normally on a wired network, this procedure requires temporarily disconnecting the PC from the network in order to connect to the PL1000E.

Perform the following steps in order to configure a Windows based PC that is not on a network to access the PL1000E.

Note: A crossover ethernet cable is required in order to directly connect the network adapter port (RJ-45) of the PC to the network adapter port of the PL1000E without the use of a hub or switch.

  1. Click “Start Menu”.
  1. Click “Control Panel”.
  1. Click the Internet Options (9) program.
