DeviceMaster LEDs
The DeviceMaster has network and port LEDs to indicate status. This subsection
discusses:
•
•
TX/RX LEDs
This subsection discusses RX and TX LEDs on the DeviceMaster 4-port.
Note:
DeviceMaster DIN rail models do not have TX/RX LEDs.
The RX (yellow) and TX (green) LEDs function accordingly when the cable is
attached properly to a serial device.
•
After power cycling the DeviceMaster, the RX/TX LEDs are off.
•
The LEDs do not function as described until the port has been opened by an
application.
•
If the port is configured for RS-232/422 mode:
-
RX LEDs (yellow) are lit
-
TX LEDs (green) are lit when as the data exits the port
•
If the port is configured for RS-485 mode:
-
RX LEDs (yellow) are lit while receiving
-
TX LEDs (green) are lit during active data transmission
Network and Device
LEDs
The LEDs indicate that the default DeviceMaster application is running. If you
have loaded PortVision DX, you can check the DeviceMaster status on-line.
