40 Appendix A: Troubleshooting

➘ Not enough memory to allocate grab buffer

This is the message that you will receive if you try to allocate a grab buffer that is

greater than the amount of DMA memory specified during software installation.

This problem can be addressed by changing the amount of DMA memory on

your computer. Re-allocate DMA memory using the included milconfig.exe utility.

Alternatively, uninstall and reinstall MIL and specify the appropriate amount of

DMA memory.

Grabbing Problems

➘

The trigger pulse is not being sent

This happens when the opto-isolated trigger pulse is not connected. When using

the opto-isolated trigger, both OPTOTRIG- and OPTOTRIG+ signals must be

connected. OPTOTRIG- is usually connected to the ground of the trigger source.

➘ IRQ conflicts

In general, PCI devices can share an interrupt line (IRQ). However, sometimes

this might not be possible. The types of difficulties that you might run into are as

follows:

• IRQ conflict under Windows 2000/XP

- To resolve this problem with the PCI form factor, re-assign a different IRQ line

to the PCI slot in which the Matrox Meteor-II board is installed.

- To resolve this problem with the PC/104-Plus form factor, change the rotary

switch settings.

❖ Note that PCI devices cannot share interrupt lines with EISA or ISA devices.

Other possible solutions to the above problems:

- Move the Matrox Meteor-II board to another (free) PCI slot.

- Swap Matrox Meteor-II with another board, by switching PCI slots.
