ADLINK ACL-8112 Data Acquisition Card Configuration and Programming

Check if the interrupt service program is installed correctly and clear the interrupt (write any value to BASE+8);

Confirm that the interrupt vector is not occupied by BIOS or other drivers (run INT query).

Fault 5: Counter 0 cannot output the expected frequency

Check if the CLK jumper selects internal 2MHz;

The counting format (BCD/binary) in the control word should match the initial value (if binary counting is used, the initial value range is 0~65535; BCD is 0~9999);

Confirm that the GATE pin level is high (it may be pulled low if suspended).

Maintenance and upgrade suggestions

ISA slot gold finger should be cleaned regularly with an eraser to avoid oxidation and poor contact;

If the electrolytic capacitors on the board (especially the power filter capacitors) have been used for more than 10 years, it is recommended to replace them to prevent leakage and damage to the PCB;

For new projects, it is recommended to migrate to PCI/PCIe bus products (such as ADLINK PCI-9111/9113, etc.), but existing systems can still rely on ACL-8112 for stable service;

The driver program is included in the ADLINK CD (DOS library). If you need a Windows environment, you can purchase the ACLS-DLL2 development kit (supporting Win95/98/NT/2000).
