CONFIDENTIAL AND PROPRIETARY NRU Network Repeater Unit Product Highlights • Network device that o Repeats downlink and uplink messages. o Enables post installation testing of VLU7 while in or out of the network area. • Available in two models 1. Full function – provides complete NRU feature set. 2. ITU only - Supports only VLU installation testing. No network repeating features. The LoJack Network Repeater Unit (NRU) is a low cost network device that can be used in a LoJack Stolen Vehicle Recovery Network. The NRU was designed to replace the obsolete Tracker Repeater Unit (TRU), and the Packet Decoder used for repeating. The NRU is now available for 13 and 8 second networks. An NRU can repeat downlink transmission bursts it receives from either a Remote Transmitter Unit (RTU), another NRU, or from the network. It relays back any reply code transmission it receives from an activated Vehicle Locator Unit (VLU) as an uplink message to a tower connected to the central system. An NRU can also repeat uplink transmissions from any nearby VLU or repeaters. If connected via IP/broadband, the NRU can forward to a central system any reply code or uplink messages it hears. Finally, the NRU can be used as a mobile Installation Test Unit (ITU) for performing on-site installation verification and routine inspection of VLUs. When configured for ITU use, the NRU can send properly timed and indexed test command to the new VLU7 unit. This allows the user to perform post-installation testing of the VLU7 without the need to access the VLU7 ground wires. This powerful feature works both inside and outside network coverage areas. Product Description The NRU is a self-contained unit in an indoorrated housing with mounting tabs, and includes a built-in GPS receiver. The unit has a dedicated serial interface, connectors for power and antenna as well as relay contacts to drive an external power amplifier. The NRU fully supports VLU7 timing and indexing requirements for downlink transmissions for basic messages such as Activation, Deactivation, Speed up, and extended downlink messages such as AltDeactivate. The NRU can be used in conjunction with a GSM modem. The NRU will not repeat transmissions from a mobile transmitter with pseudo dotting 15 in 13 second networks. It will respond to either configuration or report request messages from a mobile transmitter or from the network. NOTE: The NRU is not base station certified. It is ETSI certified for 13 Second Systems and FCC certified as a mobile transmitter for 8 second Systems.
