Printer initialization
After Ethernet Card installation, the red and green status lights
on the interface flash simultaneously during printer initialization.
Network recognition and normal
operation
At start up, the Ethernet Card checks all active NetWare file
servers. While the card is recognizing the network, the red and
green status lights flash alternately on and off.
After recognizing the network, the Ethernet Card is ready to
send and receive data. In this mode, only the green status light
is lit.
Data Transmission light
When the Ethernet Card receives a data packet, it
automatically recognizes the protocol of the packet and
switches to that protocol mode. When the card sends data, the
Data Transmission light (green) is lit.
Status sheet printing

the Status Sheet button is pressed, the connected
printer prints out a status sheet showing the current card
configuration.
