RS-232C Protocol

H4: Parity

Parameter value

0

None

 

 

1

Odd

 

 

2

Even

 

 

3

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.
