FOUR PORT RS-232 SERIAL INTERFACE

2. Introduction

2.1 Overview

The Four Port RS-232 Serial Interface provides your PC system with four RS- 232 asynchronous ports. Connect to any device that uses the RS-232 protocol, such as modems, data-entry terminals, and plotters.

The Serial Interface also includes a serial utility diskette with Seacom, a DOS interrupt and driver package. Seacom allows data to be buffered, eliminating data loss in high-speed data transfers. It also allows more than

4 ports (256 max.) to be configured and utilized under DOS.

The README file on the serial utility diskette contains information about the latest changes and revisions. To view this file, insert the diskette into drive A or B and type A:TYPE READ.MEMORE [ENTER] or B:TYPE READ.MEMORE [ENTER].

2.2 What’s Included

Your Serial Interface should come with the following items. If any of these items are missing or damaged, contact your supplier.

(1)Four Port RS-232 Serial Interface with 1x DB37F,

(1)Octopus cable, (1) 3-ft. (0.9-m) to 4x DB25M,
