Regarding Technical Notes

Some technical notes are available for Obsolete or Obsolescent products. Most technical notes refer to the current a-Series of DAP boards, rather than the previous e-Series boards. The information in the technical notes is still correct, however, regardless of the "a" or "e" designation. a-Series boards originally were designed to comply with the EMC regulations instituted in the European Union. Although limited changes were made to ensure that the boards would comply, the functionality of the boards remained the same. If you have any additional questions regarding changes made in the move to a-Series boards, contact the Application Engineering group.

Parts for Older Systems

Note that the ISA DAP boards are now Obsolete. These boards may not work with operating systems including – and newer than – Windows XP. We cannot offer support for ISA boards, because current PC specifications do not include ISA support.

Our applications engineering group has assisted many customers to move to newer technology while retaining their investment in legacy systems. Contact us and we will help you select the components you need to rapidly upgrade your application to a newer DAP board with minimal development work.

Alternately, if you are ready for a larger upgrade, but need extra resources to do that, we can assist you with your new development. Our systems group can provide support ranging from one day to give you the assistance you need to get started, up to a full implementation of your new system. Contact our sales department to discuss your options.
