iSTAR LEDs on the GCM are labeled and indicate the following:
HEARTBEAT - The LED will blink rapidly while the board is waiting for
a reboot following restore-factory-default. The LED will blink slowly
otherwise.
COM1-RX - RS 485 COM1 receive data.
COM2-RX - RS 485 COM2 receive data.
COM1-TX - RS 485 COM1 transmit data.
COM2-TX - RS 485 COM2 transmit data.
RS232-RX - RS-232 (debug port) receive data.
RS232-TX - RS-232 (debug port) transmit data.
ETH1 TxRx - Ethernet 1 receive or transmit data.
ETH2 TxRx - Ethernet 2 receive or transmit data.
ETH1 100 - Carrier - Ethernet 1 is connected to a 10/100 Base network.
ETH2 100 - Carrier - Ethernet 2 is connected to a 10/100 Base network.
