Requirement of setting logic high to be +3.3V for PCI-6509 (CMOS compatible)

[ashish]

Hi, I have requirement to set logic level high for Digital Output to be +3.3V using PCI-6509 (CMOS compatible)for my system interfacing. Can it be programmed? Is this related with 3.3V LED on the PCI-6509? or related with 5V or +3.3V PCI bus, as I am using Industrial PC, not sure about the PCI bus voltages .. Thanks. ashish

Ashish,

No, the NI 6509 does not have selectable voltage levels. However, the following KnowledgeBase does offer a solution:

KnowledgeBase: 3.3 Volt TTL from Digital Products

Moreover, the NI 654x digital I/O devices do have selectable voltage levels. Below, I have included a link to the appropriate product page:

Good luck with your application.
