RS-232C Protocol (FS-C5030N only)
Parameters of the RS-232C Protocol
ADVANCED OPERATION GUIDE
A protocol is a set of rules followed by various devices to send or receive
data. The parameters of the RS-232C protocol are stored in the battery-
powered memory of the printer. You can verify these parameters on the
status printout as marked by the following identifications:
•
H1: Baud rate
•
H2: Number of data bits
•
H3: Number of stop bits
•
H4: Parity
•
H5: Protocol logic
•
H6: Buffer-nearly-full threshold
•
H7: Buffer nearly-empty threshold
•
H8: Received data buffer size
The parameters can be changed from the printer operator panel. To
change the value for the serial interface parameters, see Changing Serial
Interface Parameters (FS-C5030N only) on page 2-30.
This following section outlines the parameters and their values you can
select on the operator panel:
