    Overview of the KD485

    The KD485 is a multi-purpose isolated RS232/422/485/20mA interface converter with intelligent data processing options.

    Three standard product versions cover most industrial interface and protocol conversion applications.

    Another common requirement is multi-drop connection of non-addressable RS232/422/20mA devices, to enable them to be conveniently polled from a single RS422/485 Master device. The KD485-ADE can act as an "addressable adapter" for each RS232 device.

    Many projects involve the interconnection of equipment which is mutually incompatible. The KD485-PROG can be programmed - in ANSI C - to convert virtually any industrial automation protocol into any other. A MODBUS RTU comms library is available for rapid MODBUS RTU SLAVE protocol converter development, enabling a non-MODBUS device to appear as a MODBUS RTU SLAVE device.

    Standard Versions

    The KD485 is available in three stock versions which share the following common features:

    • DIN-rail enclosure with removable screw terminals; fits 35mm symmetric rails
    • 29mm width on DIN rail
    • DC power input in the range +7V to +35V; uses a high efficiency switching power supply
    • Two serial ports: port 1 and port 2; isolated from each other and from the power supply
    • Port 1 is RS232; port 2 is RS422/485 as standard
    • Either port can be factory-fitted as RS232, RS422/485 or 20mA Loop
    • Controlled slew rate drivers on RS422/485 ports - no terminators needed for cables shorter than 300m
    • Internal pull-up and pull-down resistors on RS422/485 ports ensure that RS485 bus floats to a valid state when not driven.


    This entry level product has no CPU. It is an interface converter/isolator only and is baud rate and character format independent. Its main application is in isolated conversion between RS232, RS422 and 20mA. It can also drive a 2-wire RS485 bus if the RS232 host provides RTS Control
