4.3.1Echelon Card Plug-In (P/N 537-4860)with mounting screw (P/N 101-4201)

Echelon is a two-conductor network that interconnects E2s and other associated devices. All Echelon devices are wired together using the daisy-chain method of network structuring. For the E2 to communicate on the Echelon Network, the plug-in card must be connected. No Echelon Network communication can occur without the card.

The plug-in Echelon card connects to the main proces- sor board on the far right side of the board just above the Power Interface Board (PIB) connector. The connector for the plug-in Echelon card is labeled Echelon Plug-Inso it is easy to find.
