NODE TEST
On Yellow
The host and MAC board are performing selfĆdiagnostic tests.
MAC FAULT
On Yellow
The MAC board has either failed the selfĆdiagnostic test, faulted while in operation, or
there is another module with the same node address on the network. A MAC fault also
causes the HOST FAULT indicator to light.
MAC TEST
On Yellow
The MAC board is performing a selfĆdiagnostic test.
SAT
On Yellow
The node has reached the peak of its ability to process messages.
ACTIVITY
