4.2.2 RS485 Network
The AcuLink 810 gateway supports RS485 serial communication. Users can setup an RS485
connection to the AcuLink with any Accuenergy or third party device. If connecting multiple
devices or 'daisy chaining' the devices together, ensure that a unique device address (Mod-
bus Slave ID) is configured for each RS485 device. The AcuLink 810 can support up to 32
external RS485 devices.
NOTE:
A termination resistor at the end of the RS485 network is optional when daisy chain-
ing multiple devices. If using resistor a termination value of 150 ohms can be used.
