The replacement 004-4INC-IO-REN-PCIE card is designed to drop in place of the 004-4INC-IO-REN-PCI card for existing and new applications. Whilst there is no change to the standard RS422 differential inputs there has been a small change to the voltage threshold when encoder inputs are used single ended.
The card will operate with any drivers from circa year 2005 onwards so there is no need to change any software.
