23.12.2015 - Comtrol RocketPort UPCI Interfaces EOL Announcement

Effective December, 2015
As an important supplier to our many valued customers, Comtrol Corporation makes every effort to assure long-term availability of our industrial communication products. Despite our best efforts to manage the product life cycle, however, on rare occasions in the case of mature products, we are faced with instances where, on short notice, a vendor is no longer able to provide a key component. Such an issue has recently come to our attention concerning a component used in the RocketPort UPCI interfaces that we have manufactured consistently over the last fifteen years.

This notice Is being issued to advise our customers that, due to this lack of availability, Comtrol is announcing the end of life and end of sale for the RocketPort UPCI interfaces listed below. A full line of replacement cards and interfaces is available in the Comtrol RocketPort Infinity PCI card family and cross referenced in the table below. These products offer many advantages over the products they replace including lower prices, identical software installation and management interface and a higher performance design. Please contact your Comtrol sales representative to discuss migration options and free evaluation models.
