2.6Description of Interface Signals

The 2 lines; TxD and RxD are used to transmit/receive signals between the equipment and the Finisher. When the Finisher is connected, the equipment detects the power supply signal (MFP-24V-ON) and confirms that the Finisher is connected to it with the status of the connection switch (SW4) and an MFP- CONNECT-SEN signal from the connection sensor (S25).

TXD:

Sent data (transmitted from the Equipment to the Finisher)

RXD:

Received data (transmitted from the Finisher to the Equipment)

MFP-24-V-ON:

Equipment 24V power supply signal (Low level - 24V power supplied)

MFP-CONNECT:

Equipment connection switch (Connected - 24V power supplied)

MFP-CONNECT-SEN: Equipment connection confirmation signal (Low level - Connected to the equipment)

Data communication (RxD and TxD) between the equipment and the Finisher has adopted the serial communication system which does not allow checking whether the signals are transmitted/ received properly using testing devices in the field.
