Data Rate Multiplier

Clock Mode	Max bps	Description
		Auto clock mode enables applications to
		request any baud rate up to 921,600.
Auto	921,600	The hardware drivers will select the
		correct clock multiplier based on the
		baud rate requested
		The X1 clock mode mimics a standard
		COM port. The hardware drivers lock
X1	115,200	the clock to the standard rate. The port
		will run at the baud rate requested by
		the application.
		The X2 clock mode locks the ports
		hardware clock at double the standard
		rate. The baud rate the port runs at will
X2	230,400	always be double the rate requested by
		the applications. This mode is useful
		for legacy applicattions which cannot
		request baud rates over 115,200
		The X4 clock mode locks the ports
		hardware clock at four times the
		standard rate. The baud rate the port
X4	460,800	runs at will always be four times the rate
		requested by the application. This mode
		is useful for legacy applications which
		cannot request baud rates over 115.200.
		The X8 clock mode locks the ports
		hardware clock at eight times the
		standard rate. The baud rate the port
X8	921,600	runs at will always be eight times the
		rate requested by the application. This
		mode is useful for legacy applications
		which cannot request baud rates over
		115.200.

6.Double click the hardware class Ports (Com and LPT). Each Quatech PCI Serial Port listed in this class is a “child device” of the DSCLP-200/300 “parent device.”

7.Open the Properties dialog for a COM port, then click the RS-422/485tab to view the settings for that port.
