1 About the ProtoCessor
ProtoCessor is a family of embedded or external low cost, high performance Building and Industrial Automation multi-
protocol gateways.
With one part number, the ProtoCessor products are pre-programmed to automatically support one to many of the same or
different OEM products to multiple different protocols.
This guide provides an overview to the ProtoCessor family of protocol gateway solutions and the steps required to utilize
each gateway option.
By adopting the ProtoCessor solution 140+ Industrial and Building Automation protocols are instantly available. The
ProtoCessor solution translates from a common Serial or Ethernet protocol on the OEM’s controller to the desired field
protocol (Serial, Ethernet or LonWorks).
The ProtoCessor is cloud ready and connects with MSA Grid. For FieldServer Manager instructions, refer to the MSA Grid -
FieldServer Manager Start-up Guide on the MSA Safety website.
1.1 Certification
BTL Mark – BACnet Testing Laboratory
The BTL Mark on the FieldServer is a symbol that indicates that a product has passed a series of
rigorous tests conducted by an independent laboratory which verifies that the product correctly
implements the BACnet features claimed in the listing. The mark is a symbol of a high-quality BACnet
product.
Go to www.BACnetInternational.net for more information about the BACnet Testing Laboratory. Click
here for the BACnet PIC Statement. BACnet is a registered trademark of ASHRAE.
LonMark Certification
LonMark International is the recognized authority for certification, education, and promotion of
interoperability standards for the benefit of manufacturers, integrators and end users. LonMark
International has developed extensive product certification standards and tests to provide the
integrator and user with confidence that products from multiple manufacturers utilizing LonMark
devices work together. MSA Safety has more LonMark Certified gateways than any other gateway
manufacturer, including the QuickServer, ProtoCessor, ProtoCarrier and ProtoNode for OEM
applications and the full featured, configurable gateways.

1.2 ProtoCessor Family of Modules
Full Function ProtoCessor and Application Specific ProtoCessor (ASP): These modules are designed on the OEM’s
controller by implementing a ProtoCessor serial TTL socket (3.3VDC to 5VDC). See voltage ranges in Section 3.1.2
ProtoCessor Pin Voltage Levels.

2 Implement the ProtoCessor from a Hardware Perspective
2.1 How to Implement the ProtoCessor Socket on OEM Hardware
The OEM needs to implement a ProtoCessor socket on the board consisting of u-shaped 2 x 10 and 1 x 8 pin headers
(reserved pins) which include the TX/RX signals power supply.
• This socket will accommodate any current and future ProtoCessor.
• The socket is populated only when the need for the protocol exists.
