RS-232C Protocol

B-7

All signals can transmit between the printer and the host computer to send 

each signal with a signal ground.

This output is used as a buffer nearly-full handshake line. It is held high 

(above 3 volts) when the buffer can accept more data.

The voltage levels of the interface signals conform to EIA RS-232C 

specifications. SPACE is from 3 volts to 15 volts. MARK is from -3 volts to 

-15 volts. Voltages between -3 volts and 3 volts are undefined.

RS-232C Protocol

A protocol is a set of rules the computer follows in sending data to the 

printer. The RS-232C parameters are stored in battery backed-up memory. 

They are indicated on the status printout. They can be changed by the 

FRPO (firmware reprogram) command described in the 

 provided on the CD-ROM supplied with the printer. The 

parameters and their identification codes are given below.

The factory setting is 9600 baud.

7 or 8, factory-set to 8.

1 or 2, factory-set to 1.
