Description of diodes of Ethernet socket:
To PC: cable with a 25 Sub-D plug 3 - TxD 2 - TxD 7 - GND
To PC: cable with a 9 Sub-D plug 2 - TxD 3 - TxD 5 - GND
Yellow diode:
is alight when the recorder is connected to the Ethernet network and is go out when the recorder is disconnected from the network
Green diode:
Tx/Rx, when the recorder uploads and downloads data, it is alight irregularly, and it is a light continuously when data are not transmitted
