Binding circuits of the interface are led out to connectors N1 to N6 of the
terminal board marked as SERIAL CHANNEL 2.
Connector Signal Signal type Use
N1 frame connection of the
shielding
N2, N4 RxD-/TxD- input/output data signal
N3, N5 RxD+/TxD+ input/output data signal
N6 GND signal ground
Interconnection is realized in the way described under item 9.5.9.
