Interpreting the Status Indicators
The status indicators on the 9220-KTCT give you information about the
card and the network when you’re connected via the BNC connectors.
The table below outlines the states, and explains what each state means
to you and the action you should take, if any, to correct that state.
• steady – indicator is on continuously in the defined state.
•
alternating – the two indicators alternate between the two defined states at the same time (applies to
both indicators viewed together). The two indicators are always in opposite states, out of phase.
• flashing – the indicator alternates between the two defined states (applies to each indicator viewed
independent of the other). If both indicators are flashing, they must flash together, in phase.

present and working
À
flashing red/off media fault check media for broken cables, loose
connectors, missing terminators, etc.
no other nodes present on network add other nodes to the network
flashing red/green incorrect network configuration cycle power or reset unit
If fault persists, contact A-B representative
or distributor.
À The configuration node is the node responsible for distributing ControlNet configuration data to all nodes on
the network.
