9.7 Bell 1/Bell 2 Indicators
The Bell 1/Bell 2 Indicators will show the status of the Bell Output and the over current or
circuit
fault conditions.
9.8 Network RX/TX Indicators
The Receive and Transmit Data Indicators are located on the right side of the PCB beside the
communication interface and below the modem circuitry. The indicator shows when the Protégé®
SE Integrated System Controller is transmitting and receiving information from the module
communications interface and is identified by the text ‘RX’ and ‘TX’.
9.9 Ethernet Link Indicator
The Ethernet Link Indicator is located next to the Ethernet connector and is labeled ‘LINK ACT’. It
will be on when the Ethernet connection has a valid link with a hub, switch or is directly connected
to a personal computer. If the link indicator is off the Ethernet cable is not connected.
The Link Act Indicator will flash for a period of 600 milliseconds when the Ethernet interface
receives or sends a valid frame.
9.10 100Mb Indicator
The 100Mb Indicator is located next to the Ethernet connector and is labeled ‘100’. It will be on
when the network communication has been successfully negotiated to operate at 100Mbs.
9.11 R1/R2 Data Indicators
The R1/R2 Data Indicators are located above the Reader 1 and Reader 2 connection terminals. A
short flash (<250 milliseconds) on the Data Indicator will show that data was received but was not
in the correct format. A long flash (>1 second) indicates that the unit has read the data and the
format was correct.
9.12 Online Indicator
The Online Indicator is located near the center of the PCB and is labeled ‘ONLINE’. The Online
Indicator shows when the modem has control of the telephone line.
