CONNECTIONS

PARALLEL2DATA SIGNAL

Pin No.		Return pin No.	Signal	From/to	Function
1	19		STROBE	PC/DCP	Strobe pulse for data reading. Incoming pulse width should
					be 0.5 ms minimum. At regular conditions, “High” data will be
					read after becoming “Low”.
2	20		DATA1 (LSB)	PC/DCP	High:		data 1
3	21		DATA2	PC/DCP	Low:		data 0
4	22		DATA3	PC/DCP	Information will be expressed for parallel data of every signal
5	23		DATA4	PC/DCP	from bit No.1 to No.8.
6	24		DATA5	PC/DCP
7	25		DATA6	PC/DCP
8	26		DATA7	PC/DCP
9	27		DATA8 (MSB)	PC/DCP
10	28			DCP/PC	This signal is yielded after data input has ended by a data
			ACK
			(ACKNOWLEDGE)		reception acknowledgment pulse.
11	29		BUSY	DCP/PC	High:		DCP data is not accepted
					Low:		DCP data is accepted
					The signal becomes “High” in the following cases;
					·	Off line status
					·	During data entry
					·	During printing
12			P·E	DCP/PC	High:		No paper
			(PAPER END)		Low:		Paper available
13			SELECT	DCP/PC	High:		INPUT switch is PARALLEL and the ON LINE
						button is pressed ON
					Low:		Other than above
16,17			GND		Earth
18			DC5V
19-30, 33			for twist pair return
32				DCP/PC	Low:		Abnormal condition occurs in DCP (e.g. error due to
		FAULT	FAULT
					paper jamming etc.)
14, 15, 34-36			NC		Unused
31	16			PC/DCP	Clears sending data. Incoming pulse width should be 100 ms
			INT
			(INITIALIZE)		minimum. At regular conditions, “High” data will be cleared
					after becoming “Low”.
