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.

Please contact the OEM vendor of your ProtoCessor to ask for the Start-up guide for the specific ProtoCessor. The output protocol can be configured a number of different ways on the ProtoCessor and the OEM Vendor will have the correct documentation on how to set it.

The ProtoCessor mapping has been pre-configured and approved by the OEM Vendor. MSA Technical Support is not authorized to change it. Please contact your OEM Vendor to inquire about any modifications to the mapping.

Please contact the OEM vendor of your ProtoCessor to ask for the Start-up guide for the specific ProtoCessor. There are several ways of changing the Device Instance on a ProtoCessor Gateway and the OEM Vendor will have the correct process documented in their Start-Up guides.

Recovery Mode occurs when an internal Module of the ProtoNodeCessor firmware has suffered a crash or corruption. A firmware upgrade will be required to resolve.
