Profile: Arrowvale Electronics provides solutions to all electronic and other manufacturing requirements. We deliver a wide range of services and products from military to medical equipment, offering the entire spectrum of turnkey project management. Our on train data recorder provides a complete record of each state change of all monitored signals. Data recording takes place in a crash survivable memory module, with journeys in excess of 24 hours duration easily accommodated. The data is protected from damage during vehicle accident, providing a secure record for incident investigations. The recorded information can be transferred to a PCMCIA memory card for routine data extraction and analysis. Our drivers interface unit is remote from the data recorder, connected via RS232. This drivers keypad includes a vandal proof 12 button telephone style keypad and a 20 character by 2 line liquid crystal back lit display. A relay is provided which is switched when the correct drivers ID is entered and it has the facility to record other information such as train reporting number. An OTMR healthy blue or multicolor LED indicates that the recorder is functioning correctly.
