Synchronization:	Asynchronous
Handshaking:	Depend on the DIP switch settings
	(DTR/DSR or XON/XOFF control)
Signal levels:	2.0 to 5.0 V:	Logic 1
	0.0 to 0.8 V:	Logic 0
Baud rates:	4800, 9600, 19200, 38400 bps
Data word lengths:	7 or 8 bits
Parity settings:	None, even, odd
Stop bits:	1 or more
Connector (printer side):	Female D-SUB25 pin connector

NOTES: • The handshaking data word length, baud rate, and parity depend on the DIP switch (Refer to Section 3.3.3)

•Data transmitted from the printer has 1 stop bit (fixed).

DR1 > DR2		CS1 > CS2 indicates that:
	Channel 1 is high.
	Channel 2 is low.
DR1 < DR2		CS1 < CS2 indicates that:
	Channel 2 is high.
	Channel 1 is low.

	CS1		CS2	Function
	H		L	Communication is available
	L		H	Communication is not available

NOTE:	•	If the electric potential of CS1 is higher than that of CS2, the printer is ready for
		communication (the host is ready to receive data). If the electric potential of CS1 is
		lower than that of CS2, the printer is not ready for communication (the host is not ready
		to receive data).
