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 condions.
9.8 Network RX/TX Indicators
The Receive and Transmit Data Indicators are located on the right side of the PCB beside the
communicaon interface and below the modem circuitry. The indicator shows when the Protégé®
SE Integrated System Controller is transming and receiving informaon from the module
communicaons interface and is idened 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 connecon has a valid link with a hub, switch or is directly connected
to a personal computer. If the link indicator is o the Ethernet cable is not connected.
The Link Act Indicator will ash 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 communicaon has been successfully negoated to operate at 100Mbs.
9.11 R1/R2 Data Indicators
The R1/R2 Data Indicators are located above the Reader 1 and Reader 2 connecon terminals. A
short ash (<250 milliseconds) on the Data Indicator will show that data was received but was not
in the correct format. A long ash (>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.
