Application and Configuration of ADLINK ECS-8582-4S Extension System

2. BP-8005 Backplane Layout

The backplane provides 5 PCI slots (system slot+4 peripheral slots), and the system slot is pre installed with PCI-8565. It is strictly prohibited to insert any CPU card or other controller, otherwise it may damage the backplane or devices.

Key connectors:

CN2 (ATX power connector): 20 pin standard ATX power interface, connected to a built-in 200W power supply.

CN3 (fan connector): 3-pin, providing power to an 80mm fan (+12V).

CN4 (Power OK status): Provides PW-OK signal for ATX power supply for host monitoring.

JP2 (ATX power enable): 2-pin, short circuited to remotely turn on the power (in conjunction with JP1 of PCI-8565).

CN1/JP1 (LED connector): Used to connect the power indicator light on the front panel of the chassis.

All jumpers and connectors have clear silk screen printing, please wire them as needed.

Common problems and troubleshooting

Q1: What is the maximum extension distance?

Answer: The longest is 7 meters. Linghua provides three types of cables: 1-meter, 3-meter, and 7-meter (part numbers ACL-EXPRESS-1/3/7).

Q2: Do additional drivers need to be installed?

Answer: No need. Due to the use of a transparent PCIe to PCI bridge and native support of the operating system, no special drivers are required.

Q3: Can a host connect to multiple expansion enclosures?

Answer: PCIe is a point-to-point architecture, and one ExpressCard slot can only connect to one chassis. But theoretically, the PCI bus allows a maximum of 255 bus segments. If the host has multiple ExpressCard slots, it can be connected to multiple chassis separately, but is limited by BIOS and operating system.

Q4: What should I do if I encounter compatibility issues (such as unrecognized boards or resource conflicts)?

Answer: Compatibility issues mostly stem from the BIOS's allocation strategy for multiple PCI bridge resources. Suggestion:

Upgrade the laptop BIOS to the latest version.

Disable unnecessary onboard devices (such as parallel ports, serial ports, audio, etc.) in BIOS to free up resources.

Remove all non essential PCI devices (such as WiFi cards) inside the laptop.

Try inserting EC-8560 into different ExpressCard slots (if available).

Priority should be given to laptops with Intel 945, 965, or newer chipsets, as these chipsets provide better support for multiple PCI bridges.

Q5: Is the power capacity of the expansion chassis sufficient?

Answer: The chassis is equipped with a 200W power supply. In addition to PCI-8565 (approximately 2.4W), the remaining power can be used for 4 standard PCI cards (generally not exceeding 25W per card), but the total power consumption needs to be calculated to not exceed the rated power supply.

Q6: Can full-length PCI cards be used in the expansion chassis?

Answer: No. The RK-8005 chassis only supports half height (half length) PCI cards and cannot accommodate full-length cards.

Maintenance and safety precautions

The chassis should be placed in a well ventilated and dust-free environment to ensure the normal operation of the fan.

Regularly clean the ventilation holes of the chassis to prevent dust accumulation and overheating.

The bending radius of the cable should not be too small to avoid damaging the internal shielding layer.

If not used for a long time, the power should be cut off and the power plug should be unplugged.

The built-in power supply of the chassis has no switch and needs to be controlled by plugging and unplugging the power cord. Before powering on, it is necessary to confirm the voltage matching (100-240VAC).

Typical application scenarios

Portable testing platform: Engineers carry laptops and lightweight 4-slot chassis to complete tasks such as electronic manufacturing testing and signal analysis on site.

High density I/O system: By expanding the chassis and installing multiple data acquisition cards (such as analog input, digital I/O, counter cards), multi-channel synchronous acquisition can be achieved.

Remote control: In hazardous or space limited environments, place the chassis remotely and operate it in a safe area through long cables.

R&D debugging: No need to disassemble the desktop computer, directly use a laptop to debug the newly developed PCI board.
