The external dimensions of MXE-5500 are 230mm (width) × 204mm (depth) × 90mm (height), and the weight is about 4kg. When installing on the wall, attention should be paid to:

Remove the 4 plastic foot pads at the bottom and the side screws.

Fix the two wall brackets to the chassis with 6 M4 screws.

Key Warning: The manual specifically states that 'To maintain structural integrity, the device should not be wall mounted with the rear panel on the bottom.' It is prohibited to wall mount the rear panel in a downward direction to avoid affecting structural strength and heat dissipation.

1.3 Requirements for heat dissipation spacing

The CPU and PCH heat source components of MXE-5500 are located at the top of the system and directly contact the heat dissipation fins through thermal pads. To ensure the efficiency of natural convection heat dissipation, at least 2 inches (5cm) of clearance should be left at the top. Wide temperature models (-20 ° C to 60/70 ° C) need to be used with industrial grade SSDs or CFast cards.

Chapter 2: Internal Module Installation - Hard Disk, CFast, and Mini PCIe

2.1 Installation of 2.5-inch SATA hard drive/SSD

Place the 2.5-inch HDD or SSD into the bracket and secure it with 4 M3 screws.

Slide the bracket back into the slot until the SATA connector is fully engaged, then unscrew the thumb screw.

Repeat the steps to install the left hard drive.

Attention: If using HDD (mechanical hard disk), the vibration tolerance is 0.5Grms; If SSD is used, the vibration tolerance can be increased to 5Grms, and industrial grade SSD must be selected for wide temperature applications.

2.2 CFast card installation

The system rear panel provides CFast Type II slots (push push), supporting SATA-III (6.0Gb/s):

Unscrew the 2 screws on the CFast compartment cover and remove the cover plate.

Insert the CFast card in the direction of the guide rail until it is fully seated.

Reinstall the cover plate and secure the screws.

Insert the mini PCIe module into the corresponding slot at an angle of approximately 30 °, press down to level, and secure with 2 M2.5 × L5 screws.

Insert the SIM card into the USIM card slot (with the contacts facing downwards and the missing corners facing outwards).

Reinstall the top cover and secure all screws.

2.4 Internal Expansion Interface

The motherboard provides GPS module power interface (+3.3V and+5V, maximum 1A), clearing CMOS jumper (short circuit Pin2-Pin3 to restore factory settings), and external power/reset/LED extension pin (can be connected to remote control panel).

Chapter 3: Detailed Explanation of Power Connection and Peripheral Interface

3.1 DC power connection and polarity confirmation

MXE-5500 adopts 9-32V DC wide voltage input, 3-pin pluggable connector (V+, chassis ground,...) V-）。 Key Warning: The manual clearly requires that "Before introducing DC power to the MXE-5500, ensure that the voltage and polarity provided are compatible with the DC input. Improper input voltage and/or polarity can be responsible for system damage." When wiring, be sure to confirm the positive and negative poles, and it is recommended to use a 160W power adapter.

3.2 Isolation DI/O (DB-26P) Detailed Explanation

The MXE-5500 provides 8 isolated digital inputs and 8 isolated digital outputs (1.5kV isolated), which are led out through the DB-26P interface. Its electrical specifications:

DI: Logic high 5~24V, logic low 0~1.5V, input resistance 2.4k Ω @ 0.5W, supports interrupt triggering.

DO: Open drain N-channel MOSFET output, 250mA per channel @ 60 ° C (100% duty cycle), external power supply 5-35V.

Important: The DO output must be connected to an external VDD power supply (via pin 8 of DB-26P+VDD) to form a freewheeling circuit. When driving inductive loads (relays, motors, solenoid valves), attention should be paid to flywheel diode protection.

Optional terminal board (DIN-37D-01) and dedicated cable (30-01143-0000) for easy on-site wiring.

3.3 Multi display configuration

The MXE-5500 supports three independent display outputs, implemented through two DisplayPorts and one DVI-I

DP+DP+VGA: Analog VGA signal output through DVI-I.

Optional DisplayPort to VGA/DVI/HDMI adapter cable (see Table 1-3 in the manual for specific part numbers).

3.4 Serial port configuration

All 6 COM ports are DB-9 interfaces, among which COM1~COM4 can be configured as RS-232/422/485 mode in BIOS, and COM5/COM6 are fixed as RS-232. The pin definition is detailed in Table 1-6 of the manual, and an external terminal resistor is required for RS-485 mode.

Chapter 4: Watchdog Timer (WDT) and DI/O Programming Practice

MXE-5500 provides API based watchdog and DI/O library, suitable for Windows environments.

4.1 Watchdog Timer (WDT)

Working principle: After startup, the application needs to periodically "feed the dog", and if the timeout occurs, the system hardware will be reset.

API call process (C/C++, including Matrix_wdt. h and Matrix_wdt. lib):

InitWDT() - Initialize WDT.

SetWDT (tick, unit) - Set timeout value, tick=1~255, unit=0 (seconds) or 1 (minutes).

StartWDT() - Start timer.

Periodically calling ResetWDT() in the business cycle to feed the dog.

StopWDT() - Stop the timer.

WDT in SEMA GUI: The Hardware Control Tab of SEMA Utility provides graphical WDT control with timeout values ranging from 1 to 65535 seconds. However, the manual specifically warns: "When using the watchdog feature, all partitions must be mounted as read-only to avoid file system corruption and data loss. It is not advisable to use the watchdog feature in a Windows environment, since Windows restart uses a safe shutdown procedure." To use WDT in Windows, the system partition must be set to read-only or used in conjunction with EWF/UWF.

4.2 Isolation DI/O Programming

DI/O API functions (including matrix_diffo. h and matrix_diffo. lib):

GPIOInitialize - Initialize DI/O resources.

GPI-Read (U16 * pwState) - Read the status of 8 DI channels (bit0~bit7 corresponding to channels 1~8).

GPOWrites (U16 wState) - Set up 8 DO outputs.

GPO-Read (U16 * pwState) - reads the current DO output state.

4.3 SEMA Utility Hardware Control

SEMA Utility provides rich system management functions:

System Health: Real time display of CPU/motherboard temperature, fan speed, power consumption (mA/W), running time statistics, and startup reasons.

Hardware Control: watchdog, backlight control (LVDS interface), intelligent fan control (can set trigger temperature and PWM duty cycle curve).

Hardware Monitor: Graphically displays temperature and power consumption data, supports logging (CSV format).

GPIO Tab: configurable GPIO direction, read input status, write output value, supports XOR logic operation (XorAndXor).

I2C Bus Tab: Accessing up to 4 I2C buses through BMC, supporting byte/block read and write.

User Flash Memory: Provides 512 bytes or 1KB of user readable and writable flash memory for storing device configuration parameters (addresses 0x0000~0x01F0/0x03F0, 16 byte aligned).
