The status LED on the target port side of the cable displays the operation status of the
EthernetBlaster communications cable. See

for a description of each LED

Static & Dynamic IP Addressing
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.
