Embedded co-processor module expands OEM's addressable markets with cloud connectivity and multi-protocol support


ProtoCessors are a family of low-cost TTL to RS-485, Ethernet, and LonWorks embedded coprocessor modules that enable original equipment manufacturers (OEM) to connect to the cloud and rapidly implement various industrial, building, and machine automation protocols in their products.

The ProtoCessor provides OEMs the ability to fully configure the OEM IIoT gateway module to meet specific product, customer, or application needs, yet still utilize the same socket and hardware of an OEM electronics board. The manufacturer downloads the new configuration via a downloadable file or host PC.

The ProtoCessor is BTL (BACnet Testing Laboratories) Marked, LonMark Certified, DNP3 Conformance Tested, and RoHS Compliant. These approvals and certifications assure our customers that we carry only the highest quality of products and performance.

Low-cost TTL to RS-485 embedded coprocessor module
1. SMC Device Cloud support

Register your ProtoCessor to the SMC Cloud interface for remote access to local applications, configuration, and device management

2. Rapid Time-to-Market

Minimize coding and hardware demands or changes to current OEM design

3. Reduced NRE (Non-Recurring Expenses)

Reduce costs on purchases of source code and engineering time

4. TTL Form Factor

Fits on any OEM’s PCB circuit board hardware for maximum flexibility and ease-of-installation

5. Serial, Ethernet, or LonWorks Environment Support

Provide multiple protocol support for any protocol translation as a full-featured, field-programmable OEM protocol gateway solution

6. Multi-Client Support

Ensure interoperability between any industrial and/or building automation protocols

7. BACnet COV (Change of Value)

Provide fast data communication while reducing traffic over a BACnet network

8. BACnet COV (Change of Value)

Automatically discover known devices on the network and be configured to provide the protocol translation necessary

  • Easily support one or multiple of the same or different devices without having to build any specific configuration files
  • Automatically build the configuration file of known devices and download the file
9. Configuration Auto-Selector

Enable manufacturers to pre-load multiple predefined configurations

  • Store multiple predefined configuration files
  • Select the active configuration file with DIP switches on the fly
  • Utilizing the FS-GUI (Graphical User Interface), a different configuration file can be downloaded
  • Up to a maximum of 1000 Modbus registers can be included in a configuration file
