1.1 Introduction

The ASCII interface module AS311 (hereafter called AS311) is a general purpose data communication module for Toshiba’s Programmable Controller PROSEC-T3 (hereafter called T3). By using the AS311, T3 can communicate with external devices, such as a micro computer, bar code reader, printer, display device, sensor, etc., through the serial interface RS-232C or RS-422.

The AS311 has two ports of the serial interface. One port (channel 1) can be selected either RS-232C or RS-422 by switch setting. The other port (channel 2) is RS-232C interface. These two ports can be used independently for data receiving and transmitting.

The transmission is asynchronous (start-stop system).

ASCII is used as the transmission data code.

The figure below shows the typical system configuration.

NOTE	The maximum number of AS311 that can be controlled by one T3 is not limited by
	software. However, this module consumes maximum 1 A of internal 5 Vdc power.
	Confirm that the total 5 Vdc consumed current per one power supply module is
	within the limit (7 A).
