Hardware

Pin #	Signal	Description
60	ERR*	Parallel Error – This is a status output signal from the printer. A low state
		indicates an error condition on the printer.
	HDSEL*	Floppy Head Select – Selects the side for Read/Write operations (0 = side 1,
		1 = side 0)
61	IRTX	IR Transmit Data (HPSIR or ASKIR)
62	PD6	Parallel Port Data 6 – This signal (0 to 7) provides a parallel port data signal
		and is the printer data MSB.
63	RXD2	Receive Data 2 – Serial port 2 receive data in.
64	INIT*	Parallel Initialize* – This signal initializes the printer. Output in standard
		mode, I/O in ECP/EPP mode.
	DIR*	Floppy Direction – Direction of head movement (0 = inward motion,
		1 = outward motion).
65, 66	GND	Ground
67	RTS2*	Request To Send 2 – Indicates Serial port 2 is ready to transmit data. Used
		as hardware handshake with CTS2 for low level flow control.
68	PD5	Parallel Port Data 5 – Refer to pin-58 and 80 for more information.
69	DTR2*	Data Terminal Ready 2 – Indicates Serial port 1 is powered, initialized, and
		ready. Used as hardware handshake with DSR2 for overall readiness.
70	SLCTIN*	Select In – This output signal is used to select the printer. I/O pin in
		ECP/EPP mode.
	STEP*	Floppy Step – Low pulse for each track-to-track movement of the head.
71	DCD2*	Data Carrier Detect 2 – Indicates external serial device is detecting a carrier
		signal (i.e., a communication channel is currently open). In direct connect
		environments, this input is driven by DTR2 as part of the DTR2/DSR2
		handshake.
72	PD4	Parallel Port Data 4 – Refer to pin-58 and 80 for more information.
	DSKCHG*	Floppy Disk Change – Senses the drive door is open or the diskette has been
		changed since the last drive selection.
73	DSR2*	Data Set Ready 2 – Indicates external serial device is powered, initialized,
		and ready. Used as hardware handshake with DTR2 for overall readiness.
74	PD3	Parallel Port Data 3 – Refer to pin-58 and 80 for more information.
	RDATA*	Floppy Read Data – Raw serial bit stream from drive for read operations.

75	CTS2*	Clear To Send 2 – Indicates external serial device is ready to receive data.
		Used as hardware handshake with RTS2 for low level flow control.
76	PD2	Parallel Port Data 2 – Refer to pin-58 and 80 for more information.
	WP*	Floppy Write Protect – Senses the diskette is write protected.
77	TXD2	Transmit Data 2 – Serial port 2 transmit data out

78	PD1	Parallel Port Data 1 – Refer to pin-58 and 80 for more information.
	TRK0*	Floppy Track 0 – Sense detects the head is positioned over track 0.

79	RI2*	Ring Indicator 2 – Indicates external serial device is detecting a ring
		condition. Used by software to initiate operations to answer and open the
		communications channel.
