The ProtoNode LER provides OEMs the ability to easily provide their customers with the LonWorks® output desired. The ProtoNode is a fully functioning gateway that can be mounted external to the OEM device, providing the greatest flexibility and versatility available today. The OEM, to store several different configurations in the same SKU, can simply select the correct external DIP switch to configure the ProtoNode for one of several different devices. External DIP switches can be used to set MAC address, Node ID and Baud Rates for fast installation. ProtoNode has full access to the extensive FieldServer driver library to provide the OEM with a wide range of interface protocols, or we can develop any necessary driver for interface to the OEM device.
