RS-232C

	Pin no.	Signal name			I/O	Function
	Pin no.	Signal name			direction	Function
					direction
	1		F-GND		—	Frame ground
	2		TXD		OUT	Transmitted data
	3		RXD		IN	Received data
	4		RTS		OUT	Data transmission request signal. This is al-
						ways “SPACE” when the printer is turned on.
	5		CTS		IN	This signal changes to “SPACE” when
						host computer is ready to transmit data. (In
						this instance, the printer does not check this
						signal.)
	6		N/C			Not connected
	7		S-GND		—	Signal ground
	8		N/C			Not connected
	9-10		N/C			This pin is used when using the optional
						interface board.
	11		RCH		OUT	This signal changes to “SPACE” when the
						printer is ready to receive data. (The signal
						line is same as pin 20.)
	12		N/C			Not connected.
	13		S-GND		—	Signal ground
	14				OUT	When printer error occurs (such as paper
	14		FAULT		OUT	When printer error occurs (such as paper
						out, mechanical error, etc.), this signal is
						set to “MARK”.
	15	Multi-printer TXD			OUT	Diode coupled TXD
	16	Multi-printer DTR			OUT	Diode coupled DTR
	17 to 19		N/C			This pin is used when using the optional
						interface board.
	20		DTR		OUT	Data terminal ready signal. When the printer
						is ready to receive data, this signal changes
						to “SPACE”.
	21-22		N/C			Not connected
	23 to 25		N/C			This pin is used when using the optional
						interface board.
