All transmitters, either directly or via repeaters report to the central RX250 Receiver logger. The RX250 is a single unit that combines the radio receiver, signal processing, power supplies and data logger functions.
Radio Receiver
The high performance receiver operates in the licence exempt UHF band. The receiver delivers high sensitivity and high selectivity, the received signals provide a data stream that the data logger can use.
A 50ohm SMA antenna connector is provided and can be used with a built-in compressed spring antenna, alternatively an externally mounted dipole can be used to improve range if necessary.
Data Logger
The data logger shares the same basic platform as Eltek 1000 series data loggers. In this version the power supply has been adapted for use with NimH rechargeable batteries and can provide 24 hours of standby operation in the event of mains failure.
If the batteries become discharged, the logger will go into hibernation. When the power is restored, normal logging and charging of the batteries is resumed.
