WHAT IS Monico Mobile Messenger™?

Monico Mobile Messenger™ for High Volume Applications
m3™ is designed for high volume applications requiring consistent data parameter protocol translation between CDL (CAT® Data Link) and S.A.E. J1939 or Modbus RTU. The unit is purposefully built in an environmentally sealed IP66/IP67 enclosure and designed for industrial, mobile, and off-road applications that only require a small number of parameters. The semi-transparent housing provides clear visibility to LED indicating lights configured to provide positive confirmation of power, connectivity, and data transmit/data receive.

Monico Mobile Messenger™ for Industrial Protocol Translation
The Monico Mobile Messenger, or m3™, is an OEM-oriented product that is preconfigured at the factory and perfect for high volume, repetitive industrial applications where only a small number of parameters are needed. m3 standard data map includes up to 50 parameters (if available) and can translate Modbus RTU over RS485, CDL over CAT® Data Link, and S.A.E. J1939 over CANbus. With the ability to communicate over proprietary CAT Data Link and convert this information into S.A.E. J1939, m3 can be used for many applications to interface thousands of CAT engines and generator sets to more modern control and monitoring solutions in the industrial mobile, marine, off-road, and construction markets.
m3 is easy to mount and was specifically designed for rugged service in heavy industrial applications and mobile equipment. This device is environmentally sealed to protect against dust ingress, high volume water spray, and immersion in up to 1 meter of water (IP66 & IP67). Operating temperatures for this device are between – 40ºC and 70ºC. m3’s IP66/67 enclosure, vibration-resistant design, and wide thermal environment design make it a great choice for mobile machinery while maintaining visible LED’s for communication and power confirmation.

FAQs
Frequently Asked Questions
What is the Monico Mobile Messenger™ (m3™) used for?
m3™ is designed for OEMs and high-volume users who need reliable, repeatable protocol translation between CAT® Data Link (CDL), S.A.E. J1939, and Modbus RTU. It’s ideal for mobile, marine, off-road, and industrial applications where only a small number of data points are needed.
What protocols does m3™ support?
m3™ supports translation between:
- CDL (CAT® Data Link)
- S.A.E. J1939 over CANbus
- Modbus RTU over RS485
This makes it suitable for interfacing CAT® engines or gensets with newer control systems.
What makes m3™ suitable for rugged environments?
m3™ is housed in an IP66/IP67-rated enclosure, meaning it’s sealed against dust, high-pressure spray, and immersion in water up to 1 meter. It’s also built with vibration resistance and operates in extreme temperatures from -40°C to +70°C — ideal for off-road and mobile machinery.
What connectors does it use?
m3™ is equipped with industry-standard DEUTSCH® connectors, ensuring compatibility and durability in harsh operating conditions.
How is m3™ different from other Monico gateways?
Unlike our larger configurable gateways, the m3™ is factory-programmed, application-specific, and optimized for high-volume deployments. It focuses on translating a small set of key parameters quickly and reliably, making it perfect for use cases where minimal configuration and ruggedness are priorities.
How many parameters can it translate?
m3™ can map and transmit up to 50 key parameters, depending on the availability of data from the equipment it’s connected to. These are selected and programmed at the factory for consistent, streamlined deployment.
Is the m3™ device customizable?
m3™ is not field-configurable; it is pre-programmed at the factory based on the specific application. This ensures consistency in high-volume production environments and simplifies installation and deployment.
How does m3™ confirm it’s working correctly in the field?
The unit features a semi-transparent housing with LED indicators for power, connectivity, and data transmission. These provide visual confirmation to installers and technicians during setup and troubleshooting.
