Pertech A470 manual Parallel Interface, Flow Control

A470 Users Guide

Flow Control

The RS-232 interface uses either XON/XOFF(Software) or RTS/CTS (Hardware) protocol. This is set via dipswitch A 7. For the selected serial interface Flow Control of XON/XOFF, a particular character is sent back and forth between the host computer and the printer to regulate the communication. For RTS/CTS, changes in the RTS/CTS signal coordinate the information flow.

Parallel Interface

The Parallel interface is compatible with IEEE 1284 Parallel Interface Standards. Using the Parallel interface with the printer requires that you set Dip Switches A1, A2, A3 to the Closed position.
