Input Mode - the drive receives the continuously transmitted data, multiplies by a scaling factor andwrites to a user-defined destination parameter. - RS232 allows simple one-to-one connection to a 9-way PC serial port. Ideal for commissioning. - ANSI protocol fully compatible with Control Techniques CDE and Mentor II ranges of drives. - Up to 1200 m cable length - Up to 15 drives on one link without repeaters. - UniSoft, VTCSoft and SystemWise fully supported.   Network - RS485 and RS232 ports both optically-isolated - Data rates from 4800 bits/sec to 19200 bits/sec - Up to 1200m network length at 19200 bits/sec - Up to 15 nodes without network repeaters - Supports ANSIx3.28-2.5-4 protocol in slave mode   Environment - Ambient Temperature: -5ºC to +40ºC - Storage Temperature: -40ºC to +50ºC - Weight: 124g - Maximum Altitude: 4000 m - Humidity: +5% to +95% at 40ºC non-condensing
