ADLINK MCM-204 Edge DAQ Deployment Configuration Guide

ADLINK MCM-204 Edge DAQ Platform Deployment and Configuration Complete Manual

In the evolution of Industrial Internet of Things (IIoT) and predictive maintenance, edge computing is becoming a key bridge connecting field sensors and IT systems. The MCM-204 launched by ADLINK is an independent Ethernet Data Acquisition (DAQ) edge platform designed specifically for distributed vibration monitoring and status detection. Unlike traditional card DAQ, MCM-204 is equipped with a Cortex-A9 processor RESTful API、 The streaming SDK and web-based configuration console can collect raw vibration signals while completing data preprocessing such as FFT, power spectrum, and direct frequency (OA) at the edge, significantly reducing network bandwidth and backend server computational pressure. This article will systematically review the deployment process and core practices of MCM-204 from hardware installation, network configuration, web console operation, DAQ task settings, custom filtering algorithms to typical application scenarios, providing on-site engineers and system integrators with an immediately implementable technical reference.

Hardware installation and interface specifications

MCM-204 adopts a compact metal shell (110.5 × 40 × 126.5 mm), with a protection level of IP30, and supports two installation methods: DIN rail and wall mounting (wall mounting bracket is an optional accessory, P/N 34-51112-0000). Its interface layout is clear and divided into the following categories:

1.1 Analog Input (BNC)

4-channel synchronous sampling, 24 bit Δ - ∑ ADC, maximum sampling rate of 128 kS/s, adjustable gear: 1 k、2k、4k、8k、16k、32k、64k、128k。

The input range can be selected as ± 10 V or ± 1.25 V, with pseudo differential input and switchable coupling mode DC/AC.

IEPE incentive: Each channel provides a 4 mA constant current source, compliant with a voltage of+24 V, which can directly drive the IEPE accelerometer without the need for an external regulator.

Overvoltage protection ± 50 V, input impedance 200 k Ω (between positive and negative terminals), negative terminal to analog ground 115 Ω, analog ground to chassis isolation 1.5 kVDC.

Frequency response: -3 dB bandwidth of 0.43 x sampling rate, passband flatness of ± 0.01 dB (10 Hz~10 kHz), AC cut-off frequencies of 0.4 Hz (-3 dB) and 2.4 Hz (-0.1 dB).

1.2 Isolated digital I/O (6-pin spring terminal)

4 channels, each channel can be independently configured as input or output (set through the web console).

Input logic level: Low ≤ 0.8 V, High ≥ 2.0 V; Output is open drain and supports 5V TTL.

Special feature: DI0 supports tachometer input (0.6 Hz~500 kHz) or external digital trigger input.

1.3 Temperature sensor input

Comes with TI LMT01 digital temperature sensor (with 3-meter cable), measuring range -50 ℃~150 ℃, can be used to monitor motor housing or ambient temperature.

1.4 Dual Gigabit Ethernet and USB

Two RJ-45 ports share the same MAC address and support cascading (daisy chain), but circular connections are prohibited to prevent network communication failure.

The default static IP is 169.254.1.1, which can also be automatically obtained through DHCP or link local mode.

The USB 2.0 port is only for use with Wi Fi dongles (please consult ADLINK for support models).

1.5 Reset pin and LED indicator light

Press and hold the reset hole with a paper clip for 3 seconds to restore the factory settings (network settings can be selected to be retained).

Four LEDs on the front panel: PWR (power), SYS (system status), I/O (data acquisition activity), USB (device read-write).

Power supply and start-up process

MCM-204 adopts a 9-30 VDC wide voltage input (optional 40W AC-DC adapter, P/N 31-62138-0000）， The maximum power consumption is 8.8 W. The terminal block is spring type, and it is recommended to use a straight screwdriver to press the orange release hole and insert the wire.

Start sequence:

First, connect the Ethernet cable to the PC or switch, and then turn on the power (if the cable is not connected before startup, the device will enter a self check process of about 3 minutes).

The PWR LED remains constantly red, while the SYS LED flashes red for about 35 seconds before turning green, indicating that the system is ready.

Set the same network segment IP (such as 169.254.1. x) or enable DHCP/link local on the PC for browser access http://169.254.1.1 Or log in to the web console using the device hostname (provided on the label).

Default username: administrator, password: Adlink6166.

Full functional analysis of web console

The core management interface of MCM-204 is the built-in web console (Chrome browser is recommended), which can complete all configurations without installing dedicated software. The main menu includes:

3.1 System Information

Display firmware version, hardware information, I/O channel status, network parameters, and runtime. Can serve as a diagnostic entry point.

3.2 Peripheral Management

Real time viewing of the current level status of 4 DI/O channels, and the ability to switch the input/output direction of each channel. Simultaneously display the temperature sensor reading.

3.3 Data History

Retrieve stored historical collection data by time period (if data persistence is enabled).
