Kyocera FS-1920 manual Table B-6, Table B-7, Parameter value Meaning

RS-232C Protocol

H4: Parity

Parameter value	Meaning
0	None
1	Odd
2	Even
3	Ignore

Table B-6

The factory setting is “None” (0 on the status printout).

H5: Protocol logic

Parameter value	Meaning
0	Combination of 1 and 3 below
1	DTR/DSR, positive logic
2	DTR/DSR, negative logic
3	XON/XOFF
4	ETX/ACK
5	XON/XOFF recognized only as protocol

Table B-7

The factory setting is 0.

H6: Buffer nearly-full threshold

This is a percentage from 0 to 99. The factory setting is 90.

H7: Buffer nearly-empty threshold

This is a percentage from 0 to 99. The factory setting is 70.

The factory settings of the buffer nearly-full and nearly-empty thresholds (H6 and H7) are subject to change without notification.

The gap between the nearly-full and nearly-empty thresholds allows the computer to send a fairly large amount of data in a continuous stream.

H8: Received-data buffer size

This is the size of the input buffer, specified in units of 10 Kbytes. The factory-set value is 6, meaning 60 Kbytes.

	Since DTR/DSR protocol is not used with the RS-422A standard, select a
	parameter value other than 0, 1, or 2 for the H5 setting when using the
Note	RS-422A interface.
