Welcome to Smart Embedded Systems (SES): Company with SOFT HART MODEMTM

SES prides itself being the first company to offer firmware based HART modems. We are now offering two different soft modems:

  • 9600/1200 bps HART modem compatible with FieldComm Group physical layer C8PSK standards
  • 1200 bps HART modem compatible with FieldComm Group FSK modem standards

These modems work with any third party HART stack and we provide support documentation to integrate our modem for complete HART device solution.

In addition, we also provide HART stack with our soft modem (9600/1200 bps or 1200 bps only) and the combination of HART Stack and modem firmware is offered with a single microcontroller; presently on TI’s MSP 430 family microcontroller.

SES also provides full turnkey development and testing services for HART devices. Depending upon the architecture of other microcontrollers, our soft modem can be ported to other platforms.

Today, all HART devices operate at 1200 bps and it is hard to believe but true that there has not been significant advancement in the speed for physical layer communication for the past 20 years to increase the through put of the HART field devices. Now, SES has made that possible…

SES’s solution for 9600/1200 bps modem is the first of its kind in the world. SES’s offering of 9600 bps modem will enhance efficiency and productivity in the field of industrial automation. With 9600 bps, the throughput of these HART based field devices will increase by fivefold on the average.

Benefits of 9600/1200 bps Soft HART modem

  • Higher ( as much as fivefold increase) throughput
  • Lower cost with the integration of the stack in the same microcontroller
  • Lower power
  • High reliability
  • Easy to upgrade for fixes in the future
  • Smaller footprint
  • Higher Security


  • Process control and factory automation.
  • Temperature sensors
  • Flow transmitters
  • Level transmitters
  • Pressure transmitters
