Introduction

ISC-1112 series are industrial media converters provide media conversion between RS-232 and RS-422/485 interface. ISC-1112 series are ABS housing

design and supporting an operating temperature of -10 to 70˚C. The RS-485 control is completely transparent to the user and software written for half-

duplex operation without any modification. ISC-1112-I opto-isolators provide 3000VDC of isolation to protect the host computer from destructive voltage

spikes. Therefore, the ISC-1112 series is reliable serial media converter and can satisfy most demand of operating environment.
