23 Protégé System Controller Installation Manual
5V Isolated Power Indicator
The module communicates using an isolated RS-485 interface for optimal performance and
this requires an isolated supply on the N+ and N- terminals of the module network interface.
When a valid supply is input, the '5V ISO' indicator will illuminate.
Bell 1/Bell 2 Indicators
The Bell 1 and Bell 2 indicators will show the status of the Bell Output and the over current or
circuit fault conditions.
ON Bell is ON .
TWO FLASHES Bell is ON , the circuit is in Over Current
Protection.
THREE FLASHES Bell is OFF , the circuit to the siren/bell device
is cut, damaged or tampered.
Network RX/TX Indicator
The Slave Receive and Transmit Data indicators are located on the right side of the PCB
beside the slave communication interface and below the modem circuitry. The indicator shows
when the Protégé System Controller is transmitting and receiving information from the
module communications interface and is identified by the text 'RX' and 'TX'.
Ethernet Link Indicator
The link indicator is ON when the ethernet connection has a valid link with a hub, switch or is
directly connected using a crossover cable to a personal computer. If the link indicator is OFF
the ethernet cable is not connected.
Data Indicator
The data indicator will FLASH for a period of 600 Milliseconds when the ethernet interface
receives or sends a valid frame.
100MB Indicator
The 100MB indicator will be ON when the network communication has been successfully
negotiated to operate at 100Mbs.
