The RDL8500 remote data logger is a data logger for the TapWatch submetering system. The RDL8500 interfaces to the wireless network for collection of utility consumption data, stores the collected data, and transfers the data to a remote billing server for bill generation. A PC running TapWatch 3 software is used to access the RDL8500. The RDL8500 communicates with both Frequency Agile (FA) and EchoStream wireless networks simultaneously.
