2.8.6 Transmit data LED
This LED monitors the data sent by the application (i.e. the Data Terminal Equipment) to the DTE
interface module of the Crocus CNV.
Note that the data is monitored after it went through the interface circuitry. Some interfaces (Bridge and
Router) add framing information which activates the TXD LED even if no real user data is being
transmitted.
2.8.7 Receive data LED
This LED monitors the data sent to the application (i.e. the Data Terminal Equipment) by the DTE
interface module of the Crocus CNV.
Note that the data is monitored before it went through the interface circuitry. Some interfaces (Bridge and
Router) used on the remote side add framing information which activates the RXD LED even if no real
user data is being received.
