Sync board Failure Indicator for incomplete cable connections

The CTM SYNC LED will flash steadily red if there is no activity on the Rx port on the terminal block of the SPM

(R+ and R- on the connector). If both transmit and receive connections are cut off from the sync hub the

indicator will flash red. If only the transmit connection is disconnected and there are other Readers in the

synchronization network, the CTM SYNC LED stays green.
