IK121 Data Capture card settings
You have to set right settings for this card to get it working properly. Use msd.exe in Windows 3.11 or System Property sheet from Control Panel in Windows 95 to check already used IRQs and IO addresses. After this configure your IK121 so that it doesn't overlap or conflict with those occupied addresses.

Interrupts (IRQ):

Select a vacant IRQ for the axis you are using (for DBB you need only one axis, either Axis 1 or Axis 2). And then remove the jumper from the another axis. In the picture above you can the default settings: IRQ15 for Axis 1 and IRQ12 for Axis 2.

Notice: In new computers IRQ15 is often occupied, so you might have problems with first axis when the second axis is working properly, if you just plug in your brand new IK121.

IO-Address:

Here below you can see some examples of switch settings for a couple of IO-addresses:

IO Address (in hex):	Switch 1:	Switch 2:	Switch 3:	Switch 4:	Switch 5:	Switch 6:
110	Off	On	On	On	Off	On
250	Off	On	Off	On	On	Off
300	On	On	On	On	Off	Off
310	Off	On	On	On	Off	Off
320	On	Off	On	On	Off	Off
330	Off	Off	On	On	Off	Off
