Only IP-enabled PakBus data loggers (CR200X-series, CR800, CR850, CR1000, and CR3000) can be used with LoggerLink for iOS. IP connectivity can be set up using an Ethernet interface such as the NL115, a network link interface such as the NL240, or a cellular digital modem. In addition to these IP connectivity methods, LoggerLink for Android works with Bluetooth communications using an RS-232-to-Bluetooth adapter.
