R46 Circuit Diagram (8/15, 9/15)
1.
Block diagram
R46-PCB circuit diagram (8/15, 9/15) shown the consists of the following connectors:
• Connector CN10 that provides an interface between R46 board and NCU/G4N board.
• Connector CN3 that provides an interface between R46 board and external electro-mechanical
conponents (PC1 and PC2).
• Connector CN4 that provides an interface between R46 board and OPE (O4W) unit.
Figure A.24 (1/4) shows an interface between R46 board and NCU board.
Figure A.24 (2/4) shows an interface between R46 board and OPE unit.
Figure A.24 (3/4) shows the communication signal between MCNT and OPE.
Figure A.24 (4/4) shows the related signals of PC1 and PC2.

Function
1)
External status supervising interface (PC1/PC2)
External status is detected by the photocouplers (PC1/PC2) in the mechanism and the
signal is output to the input port of CPU1 via this interface circuit.
• PC1 : Presence of document on hopper.
When sub-power supply is applied to the fax machine, this signal is output to OPE
unit which will control the main-power supply.
• PC2 : Presence of document at scanning position.
3.
Others
NCU interface signal
• CML
: Line seizure control signal
• DP
: Dial pulse control signal
• SR
: Control signal for connection between LINE and TEL terminals
• MUTE
: Control signal for pulse dial improvement and bell shunt relay
• PP
: Relay control signal for special service code detection at parallel pickup or remote
reception
• PBXE
: Control signal for connecting one of LINE terminal to the PBXE terminal
• OH2-N
: Detection of off-hook of terminal connected to TEL
• RP
: Receiving sensitivity determination terminal
• RI
: Ringing detection signal
• S
: Send signal (picture data/protocol/tonal signals/PB tone etc.)
• R
: Received signal (picture data/protocol/tonal signals etc.)
OPE interface signals
• TXDOPE : This signal transmits sequencially the contents of each data of TXD (LED on/off
information, etc.) to OPE in serial data from CPU.
• RXDOPE : This signal transmits sequencially the contents of each data of RXD (key code
information, etc.) to CPU in serial data from OPE.
• OPECHK : Use to monitor the operation of the OPE unit.
• OPERST : Reset signal for OPE unit
G4N interface signals
