On the computer serial port, investigate pin assignments depends on the computer manufactureÕs instruction. Since the RS-422A configuration does not employ control lines except for data transmission/reception, select a mode in which signals such as DTR are not used.

Protocol

The serial interface supports the full baud rate of: 1200, 2400, 4800, 9600, and 19200, 38400, 57600 and 115.2 k (bps). For adjusting serial interface parameters including baud rate, parity, etc., refer to optional Serial interface board User’s Manual.
