Notice of Backwards Compatible Board for Pinnacle Users

The new Sigma Series Pinnacle PCX has rolled out with a lot of new features. A new Electronic Control Board is included to support many of these features. You will notice that the new boards are blue in color and have a USB connection replacing the RS-232 connection.

Customers with the older Delta Series Pinnacle PCX will have to purchase a backwards compatible board if they experience a board failure.

The backwards compatible board will have a slightly different relay connector to fit properly in the old chassis. The backwards compatible boards will have the most recent firmware, software, and also include a USB cable. Make sure to have your Pinnacle PCX Serial Number handy when ordering a replacement board.
