1. Introduction

The industrial converter is designed to convert RS-232 signals to opti- cally isolated, balanced, full or half-duplex RS-422 or RS-485 signals at baud rate up to 115.2Kbps. It features RTS control design, which allows software to control RS-485 transmission. With smart ADCTM (Auto Data Control) design, the converter can uses send data signal to control RS- 485 transmission automatically so no software control is required in RS- 485 mode. The Din-rail mountable design makes it ideal for industrial cabinets and enclosures. Further, more designs such as signal protec- tion, wide operating temperature range, wide power voltage range are provided to suit for more industrial applications.

For industrial environment, the converters are designed with the follow- ing enhanced features exceeding that of commercial media converters:

High and wide operating Temperature

Wide operating voltage range for DC power input

Power input interface: Industrial screw terminal block and DC power jack for external commercial power adapter as option

DIN rail mounting support for industrial enclosure

Screw panel mounting support for industrial enclosure

Industrial-rated Emission and Immunity performance
