Echelon Network and Hardware Setup Overview Echelon is an optional, two-conductor network that interconnects E2s and other associated devices, such as CC-100 case controllers, TD3 temperature displays, and ESR8 evaporator stepper regulator boards. All Echelon devices are wired together using the daisy-chain method of network structuring. If an Echelon network-enabled E2 is required, it must be specifically ordered from Retail Solutions as an Echelon-enabled E2, and equipped with an Echelon plug-in card.
