What if the NPR 2000 goes away until I cycle power to get it back?

Resolution

If it continues to communicate on the Ethernet port or the controller LAN port only, it most likely is a firmware (.bin file) issue. If an NPR stops communicating over the Ethernet as well as the controller LAN and the LEDs on the unit are totally abnormal until you cycle power, it very likely may need a new boot load.

This is accomplished by ordering a jtag cable and the boot loader software and downloading the flash rom with a new boot load. The latest boot load revision is 1.02. If this load has been installed at the factory, you will find a sticker on the flash rom chip. We recommend that if you upgrade the boot load yourself, that you label the unit appropriately.
