ADLINK EOS-2000 Visual System Installation and Troubleshooting

Digital I/O driver (requires ADLINK dedicated driver, similar to PCMe-1432 DIO library).

Image acquisition driver (four-way analog acquisition, requires installation of dedicated SDK or driver, specific to the random CD).

Due to the EOS-2000 positioning simulation acquisition, its acquisition function is usually implemented through APIs or DirectShow filters provided by the manufacturer. Developers need to refer to the corresponding software development kit.

3.3 Key BIOS Settings

Startup sequence: If starting from a CF card, the CF needs to be set as the first boot device in the BIOS (CF is usually recognized as an IDE device).

Serial port mode: COM1/COM2 can switch between RS-232/422/485 in the Super I/O Configuration of BIOS, please ensure compatibility with external devices.

Power management: AT mode means that it automatically starts up after power failure, without the need to press the power button (suitable for unmanned operation).

Hardware monitoring: The BIOS can view CPU temperature, fan speed (if any), and voltage values for early fault warning.

Simulation video capture channel configuration and optimization

4.1 Four way NTSC/PAL input

The collection front-end of EOS-2000 supports standard composite video (CVBS) signals, and each channel can independently select the standard (NTSC or PAL). Attention should be paid when connecting the camera:

Use 75 Ω coaxial cable, with a recommended length not exceeding 100 meters (otherwise an amplifier needs to be added).

Ensure that the camera output impedance is 75 Ω and use DC coupling or AC coupling (according to the camera specifications).

If multiple cameras need to be synchronized, an external synchronization signal is required (the system does not have built-in genlock, and frame synchronization needs to be achieved through digital I/O or external synchronization sources).

4.2 Acquisition Resolution and Frame Rate

NTC: 720 × 480 @ 30 fps (or 29.97 fps)

PAL：720×576 @ 25 fps

When collecting data from four channels simultaneously, the system needs to process a data stream of approximately 4 × (720 × 576 × 25) ≈ 41 MB/s (YUV format). The Core2 Duo P8400 combined with the GM45 integrated graphics card is sufficient to handle it. However, if complex image processing algorithms are involved (such as edge detection and template matching), it is recommended to optimize the algorithm code and utilize multi-threaded parallel processing.

4.3 Image acquisition driver and API

ADLINK typically provides interfaces based on DirectShow or proprietary SDKs. Suggestions for development:

Use double buffering or ring buffering mechanism to avoid frame loss.

Set collection timeout to prevent program from hanging due to camera disconnection.

Using hardware triggering (through digital I/O input) to initiate data collection and achieve precise synchronization with external events.

16 way isolated digital I/O application and wiring guide

5.1 Electrical Parameters

Isolation voltage: 5.0 KV (to ensure that high voltage surges on industrial sites do not damage the system).

Input: Each channel can accept 5-24 VDC, and the logic high/low threshold needs to refer to the specific manual (usually 5 V threshold).

Output: Darlington transistor or MOSFET, with a current capability of approximately 100-500 mA per channel (please refer to the complete manual for details).

5.2 Typical Wiring Examples

Input: Connect proximity switches, photoelectric sensors, buttons, etc. Using an external 24V power supply, the signal is connected to the DI channel, and the common terminal is connected to DI-COM (choose common ground or common source according to NPN/PNP).

Output: Drive relay, indicator light, alarm. Note that the output is an open collector, and an external pull-up resistor or load power supply (VDD) should be connected in series with a current diode to protect the inductive load.

5.3 Interrupt function

The digital input channel can be configured as a Change Detection (COS) interrupt to capture high-speed signals (such as position triggers) and avoid CPU overhead caused by polling. The DIO interrupt registration function needs to be called in the software, and callback functions need to be written to handle events.

Common fault phenomena and troubleshooting steps

6.1 System not powered on/no display

Check if the power input is within the allowable range (DC 10-30 V or AC 100-240 V), note that there is no switch in AT mode, and it starts immediately upon power on.

Observe whether the front panel indicator light (if any) is on; If the power supply is normal but there is no display, check the VGA cable and monitor settings.

Attempt to clear the CMOS (motherboard jumper) and restore the default BIOS to eliminate configuration errors.

6.2 Simulated acquisition with no or abnormal images

No image: Check the camera power supply and video cable connection, and measure the presence of CVBS signal with an oscilloscope.

Image flicker or asynchrony: Check if the format setting (NTSC/PAL) is consistent with the camera. If NTSC is mistakenly set for PAL, scrolling or instability may occur.

Color abnormality: Check the white balance, saturation and other parameters of the acquisition card, or try to restore the default gain.
