System Interconnections

Transmit

Twin ( Primary & Secondary ) ST fibre connectors for the outgoing fibre connections to other elements of the system. The system is software configurable for single or dual fibre operation.

Receive

Twin ( Primary & Secondary ) ST fibre connectors for the incoming fibre connections from other elements of the system. The system is software configurable for single or dual fibre operation with correct operation verified and reported.

Serial

Provides serial event messages to third party logging equipment

Event Relay

A change over relay that can be configured to provide a change in status on the detection of a fault only or on any change in fault status. This output is suitable for linking to an external sounder.

Printer Out

For connection to a dot matrix or inkjet printer for printing of fault reports with a time and date stamp.

Program

With the socket provided on both the front and rear panel, a laptop computer can be

connected to this port for configured the SID and also for downloading fault logs that include a time and date stamp.

Software

A Windows based software utility is supplied for configuring not only the JNR but also all the network devices on the fault monitoring system. Each network unit is given a unique ID and name with these reported to JNR. Each fault status on the remote units is also named and stored within SID for display on the LCD screen and printing.
