Call for price


The 1103 serial interface converter provides Isolation and Auto baud capabilities, truly making it a no compromise interface converter. Isolation is important in installations where the equipment connected to the PC is either located far from the host system, or on a different power transformer circuit. Isolation on the IC485+I eliminates the effects of Ground Loop Current, a commonly neglected and misunderstood phenomenon that leads to data errors and the destruction of communications equipment.

Note: This item has a minimum order quantity (MOQ) of 25 units. Please contact your sales representative with any questions.
