Overview and installation⚓︎
The MX-V has the following connectors accessible from the outside.
- DVI connector for display
- two RJ45 Ethernet ports
- two USB type A connectors
- antenna connectors for GPS, WiFi and mobile
- 34-pin I/O connector, including serial interfaces, see below
- 34-pin I/O connector, including power and CAN, see below
- SDHC card slot
- SIM card slot
- Optional M12 connectors for ethernet (can not be combine with RJ45 ports)
KL30 is positive power terminal (red) and KL31 is negative (black). The units start when KL15 (yellow ignition input) is connected to positive input (e.g. battery voltage).
The digital out channels can both source and sink a load. When sourcing, enabling the channel (output pin) connects it to battery voltage, while sinking connects the channel to ground.
The (5+8) analog/digital in channels can measure voltages up to 32V. The difference lies in the hardware filtering where analog is filtered at 25Hz and digital at 250Hz.
Connect either Ethernet connector to a router to get an IP address through DHCP. Alternatively, connect a male to male USB-A cable between the MX-V and your workstation for direct network access.
You can also access the machine without a workstation by connecting a computer monitor along with a keyboard.
Connect the MX-V harness to a power supply in the range 9 to 32V. Then nominal voltage is 24V.
The MX-V boots automatically when power and ignition are applied. The boot time depends on the configuration. For the current development build with a lot of things enabled it takes about 15 seconds.
The Host Mobility MX-V platform runs a custom built GNU/Linux operating system. The current kernel version is 4.19. To load the kernel, the U-Boot bootloader is used. The operating system for the MX-V is installed on the on-board eMMC memory. It contains the U-boot, kernel image plus device tree as well as the root file system.
The MX-V is delivered with the operating system installed and you can login through a secure shell (SSH).
