The KDE485 C programmable converter is intended for rapid development
of devices ranging from simple protocol conversion, Modbus
interfacing, through data acquisition, telemetry, and all the way to
complex products for the IoT market.

The customer is able to leverage in-house C programming expertise, and
the license-free and widely used STM Cube IDE development kit protects
his investment by avoiding restrictive practices in software
licensing.

The KDE485 is offered in three versions: 

The standard KDE485 has Ethernet and four serial ports. The API
includes TCP/IP, TLS, HTTPS and this covers secure comms requirements
with X509 encryption and authentication. Config and firmware updates
are via USB, and can be accessed remotely via HTTP. There is also a
0-20mA output port, enabling the emulation of 4-20mA sensors. Modbus
communication is easily implemented.

The Isolated Analog version adds a 16 bit subsystem for sensing PT100,
PT1000, all eight termocouple types, 4-20mA, and voltage.

The GPS-NTP version is intended for factory LANs where the highest
security is required, mandating no internet connections, and it
delivers GPS time via an NTP server on a user defined IP.

Other options include a 22 bit ADC, and ARINC429 which enables easy
construction of products for the aviation and related markets. Other
options can be rapidly developed using an internal expansion
interface.

The KDE485 is powered from 11 to 28V DC. The power input is isolated
with a 1500V AC test voltage.

KK welcomes custom product enquiries which can be developed using the
KDE485 as a platform. Extensions already developed include LCD
displays and keypads.
