Status
Rx : Lights when the necessary data is received from the connector A of
REMOTE 1 (S-BUS data link) or while CPU (A) for S-BUS remote is down
loading a program normally.
Tx : Lights when the data is transmitted to the connector A of REMOTE 1.
Rx : Lights when the necessary data is received from the connector B or C of
REMOTE 1 (S-BUS data link) or while CPU (B) for S-BUS remote is down
loading a program normally.
Tx : Lights when the data is transmitted to the connector B or C of REMOTE 1.
The switch S8 is set to A side (MAIN).
Rx : Lights when the necessary data is received from REMOTE 2 (RS-422A).
Tx : Lights when the data is transmitted to REMOTE 2.
Lights while this board is operating.
Lights when this board is set to the primary station on the S-BUS data link.
(S2-2 is set to ON.)
Lights while the CPU is operating normally.
Lights when an error is detected in a periodic self-diagnostics.
This indicator goes out automatically when the board recovers from an error.
