SATO 200i RS232C SERIAL INTERFACE, Ready/Busy Cable Requirements, DB25, Host, Direction, 8-PIN

Unit 3: Interface Secifications

RS232C SERIAL INTERFACE

This interface is an industry standard for serially transmitting data using a wired cable. Separate transmit and receive lines enable data to flow in both directions simultaneously. Data transmitted using this protocol is defined in its parameters; baud/bps (speed), data bits, stop bit, parity, and hand-shaking method. To change the parameter settings, refer to the Programming Reference document for this product. The Programming Reference and a ready-made cable with DIN and DB9 connectors may be acquired from SATO.

Default Parameters: DSW1-4 OFF, 19200bps, 8 data bits, 1 stop bit, no parity.
