MX-4200 product line

The MX-4200 series is a high-performance, industrial-grade embedded computer product family for versatile tasks in the area of ​​M2M communication, IoT connectivity, automation, control, measurement and monitoring. Various product variants are available, customer-specific designs are possible.

Industrial interface equipment
The MX-4200 system supports a 10/100 Mbit Ethernet interface, two CAN bus interfaces in the standards 2.0A and 2.0B, RS422, RS485 and RS232 interfaces, two 480MBit / s USB host interfaces. In addition, up to 4 isolated digital inputs and 4 digital outputs are possible. The 400 MHz ARM system is equipped with 256 MB of internal flash memory and 128 MB of DDR RAM. A microSD card slot is available as a removable mass storage unit.

Modern and open Linux system
The MX-4200 is delivered with a modern, ready-to-run kernel 4 based Linux system. There are two Linux distributions available. A Debian system as well as a compact buildroot-based system. With Linux only standardized interfaces are used, so the processing time is very short and applications can be implemented quickly, simply and cost-effectively.

Power supply with wide range input
The power supply can be supplied with DC voltages between 8 and 40 volts. The supply input is reverse polarity protected and protected against overvoltages.

Intelligent control of the power supply
Optionally, an external control of the switch-on and switch-off process is available. The power is switched on and off via a status input. The shutdown process is automatically controlled by software so that a safe and controlled shutdown of the computer is ensured.

Maximum operational safety
A hardware watchdog ensures maximum availability. The very low power consumption from 1.3 watts in full operation allows the fanless operation without any further cooling being required. Also battery powered applications are possible at any time.

Action button
The ActionButton is a small concealed button that allows you to start a user-specific program. In this way, any required actions can be carried out locally in a simple manner.

With the option PowerControl, the plug for the power supply has a three-pole design. Two poles remain unchanged for the power supply of the device. The third pole is a status line which e.g. can be connected directly to the ignition terminal, the terminal 15. The device switches on only when the ignition is switched on. If the ignition is switched off, this is signaled to the operating system, which in turn signals the switch-off request to the application. The application can then perform all necessary work, such as closing files, terminating programs and services etc., and then, if necessary, shut down the operating system and shut down the computer.

Extended operating temperature

With the "Extended operating temperature" option, the MX-4200 can be operated in the following temperature ranges.

-30°C .. +80°C (non-condensing) Operation without restrictions
-40°C .. +85°C (non-condensing) Restricted operation

Restricted operation affects the integrated 4G module. Restricted operation allows the module to operate normally, but it may be possible that 3GPP specifications are not fully respected with respect to the receiver's sensitivity.


The bracket option is used to attach the MX-4200 Industrial Embedded Computer to a flat surface. This ensures a stable and easy mounting of the MX-4200.

Bracket with rubber buffer

If a fixed mounting of the MX-4200 Industrial Embedded Computer is not possible due to vibrations and impacts, the holder is available with integrated rubber buffers. This can reliably shield vibrations and impacts from the device.

DINrail holder horizontal

The horizontal DINrail option allows the MX-4200 Industrial Embedded Computer to be attached to a standard DINrail. The horizontal mounting variant is selected if the space available to the front is limited.

DINrail holder vertical

The vertical DINrail holder allows the MX-4200 Industrial Embedded Computer to be attached to a standard DINrail. The vertical mounting option is selected when the space is limited on the side.
