ADLINK MXC-6000 Industrial Control Computer Deployment and Optimization Guide

Maintenance: The fan is designed to be pluggable and can be replaced without stopping the machine when its lifespan expires or malfunctions (but it is necessary to ensure that the system power consumption is not too high).

Suggestions for heat dissipation optimization:

Ensure a ventilation space of at least 5 cm around the chassis, with the heat dissipation fins facing upwards (facilitating natural convection).

Regularly clean the accumulated dust on the heat sink with compressed air, especially in dusty workshops.

If the ambient temperature is close to 60 ℃ for a long time, it is recommended to use industrial grade wide temperature SSDs (such as -40 ℃~85 ℃) and reduce CPU load (by limiting the maximum frequency through power management).

RAID array configuration and data security

MXC-6000 supports onboard RAID 0/1 (provided by Intel QM57 chipset). Typical application scenarios:

RAID 1 (mirroring): Used for critical data redundancy, such as process parameter databases or recipe files.

RAID 0 (Stripe): Increases continuous read and write speed, suitable for high-speed image stream acquisition (but without redundancy).

Configuration steps (using Windows as an example):

Enter BIOS settings and change SATA mode to RAID.

After restarting, press Ctrl+I to enter the Intel RAID ROM interface, create a RAID volume, and select the disk.

Load Intel Rapid Storage Technology driver (F6 load) when installing the operating system.

After the system installation is completed, install RST management software to monitor the health status of the array.

Note: Two internal SATA ports and one external eSATA can participate in RAID, but it is recommended to use hard drives with the same capacity and speed. If using eSATA as a RAID member, it is necessary to ensure that the external hard drive is always connected, otherwise the array will be downgraded.

Electrical wiring and programming for isolated digital I/O

The built-in 16 channel DI and 16 channel DO are both isolated by optocouplers, with a withstand voltage of 2.5kV, suitable for industrial sites to cooperate with PLCs or relays.

Input characteristics (DI):

Input voltage range: 0-30V, threshold of approximately 5V (TTL/CMOS compatible).

Each channel has an LED indicating the status (bright indicates input high level).

Wiring: The positive pole of the external signal source is connected to the DI terminal, and the negative pole is connected to the isolated ground (ISO_SND).

Output characteristics (DO):

Darlington transistor output, open collector, maximum current 100mA/channel, withstand voltage 30V.

An external pull-up resistor or load power supply (such as a 24V relay) is required, and the other end of the load is connected to the positive pole of the external power supply, with the DO end connected to the negative pole of the power supply (low side drive).

When driving inductive loads (relays, solenoid valves), it is necessary to parallel freewheeling diodes (such as 1N4007) at both ends of the load to prevent the breakdown of the output tube due to turn off surges.

Software control:

ADLINK provides a unified DLL/API (such as DIO library) that supports read and write by bit or byte.

Under Linux, it can be accessed through the sysfs or GPIO subsystem (with kernel driver support).

Typical application: Read the status of limit switches, output control indicator lights or valves.

Troubleshooting:

If there is an error in reading the input status, check if ISO_GND is connected to the external power supply ground.

If the output driver is weak, check if the external power supply voltage is sufficient and if the current exceeds the limit.

Internal USB port - high reliability deployment of encryption dongle

The MXC-6000 provides a USB 2.0 port on the internal adapter card (not visible externally). The core value of this design lies in:

Anti accidental disconnection: External USB ports are prone to accidental contact or disconnection, resulting in software authorization failure and production line shutdown. Physical isolation of internal ports to eliminate such risks.

Anti theft: The encryption dongle is placed inside the chassis to increase physical security.

Deployment method: Open the top cover of the chassis, insert the software authorized USB dongle into the internal USB socket, and then reinstall the cover. After system startup, the port is the same as the external USB and the driver can recognize it normally.

Attention: As this port is located on the adapter card, if using a larger volume encryption dongle, it is necessary to ensure that it does not conflict with other expansion cards. Suggest using a micro encryption dog.

Serial port configuration and on-site device connection

MXC-6000 provides 4 serial ports: 2 fixed RS-232 and 2 programmable (RS-232/422/485). The programming mode is usually set in BIOS (such as setting COM3/COM4 mode in Advanced → Onboard Device Configuration).

Key points for RS-485 multi station deployment:

Signal lines A (+) and B (-) need to be connected to twisted pair cables and ensure that a 120 Ω terminal resistor is connected at both ends of the bus (if it is a multi-point network).

Using software half duplex control (RTS or automatic direction switching), ADLINK serial port drivers typically support automatic direction control (via RTS signals).
