Transmit Blinks when the instrument is transmitting data
on the network.
Receive Blinks when there is any network activity. Steady
off means there is no network activity.
Collision Remains off under normal conditions. The LED
blinks when collisions are detected. Steady blinking usually
indicates an improperly configured network (no 50-Ohm
termination, wrong type of coaxial cable, etc.).
Transmit Normal indication blinks when the instrument is
transmitting data on the network.
Receive Normal indication blinks when there is any
network activity. Steady off means there is no network
activity.
Link Remains on when the instrument connects to a hub or
host computer. If off, check the hub connection.
Power Lit when power is applied to the adapter. If not lit,
check the power connections. This indicator must be on.
Activity Blinks when there is network activity, transmitting
and receiving. No blinking when the network is active
indicates no connection to the network. Cycle the computer
