Display, buttons and ambient light
According to the datasheet, the MConn Mini has a 2.4-inch IPS colour TFT display with 320×240 resolution, 500 cd/m² brightness and a viewing angle of up to 80°. The housing is black ABS with a PMMA front screen and the unit weighs 100 g. The 4 capacitive buttons are configurable and give LED and acoustic feedback; the display also has a switchable backlight controlled by an ambient light sensor and an acoustic signal.
Communication, supply and protection
- The CAN interface is CAN 2.0 A/B (ISO 11898-2 and 11898-5) and CAN-FD capable.
- Overvoltage protection starts at about 33 V, and the unit has reverse polarity protection.
- Temperature: operation -20 … +60 °C, storage -30 … +80 °C. Environmental protection according to ISO 20653 is IP 6K8.
- In the datasheet pin assignment of the NMEA plug variant, pin 4 is CAN high, pin 5 is CAN low and pin 1 is the optional LIN bus.
Programming and accessories
The MConn Mini is programmed with MRS Applics Studio. The accessories list in the datasheet includes the Applics Studio Bundle (1.100.200.00), a Mini Display cable harness for programming (503838), a PCAN-USB interface (105358) and an NMEA 2000 connector kit (302392).
Use in projects
The MConn Mini is used in our CAN-based tank level monitoring solution for fire trucks, together with the MRS Micro PLC CAN 4 ANA controller and 2 pressure sensors: CAN tank level monitoring for fire trucks. See MRS Micro PLC CAN 4 ANA for the controller, and MRS Electronic and Displays and HMI units for other products.
