Cable Setup

Static & Dynamic IP Addressing

Cable Setup

The EthernetBlaster communications cable supports both static IP and dynamic IP addressing, the latter by means of Dynamic Host Configuration Protocol (DHCP). By default, the EthernetBlaster cable is configured at the factory to use dynamic IP addressing. Upon power up, the cable attempts to obtain an IP address from your network DHCP server. The Status LED is green and blinking while the network address is being obtained and the cable is initializing. This process may take up to two minutes.

When an IP address is obtained and the cable is ready to use, the status LED emits a steady green light. If the attempt to obtain an IP address is unsuccessful (the DHCP server may be down or absent), the cable switches to static IP addressing. The default IP address is configured to 192.168.0.50. If static IP addressing is used, you must configure your computer to an IP address in the same subnet as the cable to communicate with it. The default setting requires your address to be in the 192.168.0.X network domain.

1Refer to your operating system manual or contact your network administrator to verify that your network supports DHCP services and for instruction on how to change your IP address.

To maintain your computer’s IP address and change the EthernetBlaster communications cable’s default IP address, see “Configuring the EthernetBlaster Hardware to Use Static IP Addressing” on page 1–11.

The EthernetBlaster communications cable includes a self-hosted administrative web page, allowing you to configure various aspects of cable operation. The following section describes how to access this web page based on your mode of connection.

This section describes how to install and set up the EthernetBlaster communications cable for device configuration or programming including the following setups:
