DeviceMaster UP LEDs
The DeviceMaster UP has network and port LEDs to indicate status. This
subsection discusses:
• TX/RX LEDs
• Network and Device LEDs on Page 84
TX/RX LEDs This subsection discusses RX and TX LEDs on the DeviceMaster UP 4-port.
Note: The DeviceMaster UP 1-port and 2-port 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 UP, 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 UP application is running. If
you have loaded PortVision DX, you can check the DeviceMaster UP status on-
line.

• The Status LED on the front of the unit is lit, which indicates that
it has power and has completed the boot cycle.
Note: The Status LED flashes while booting and it takes
approximately 15 seconds for the bootloader to complete
the cycle. When the Bootloader completes the cycle, the
LED has a solid, steady light that blinks approximately
every 10 seconds.
• The red Link Act LED is lit, which indicates a working Ethernet
connection.
• If the red Duplex LED is lit, it indicates full-duplex activity.
• If the red 100 LED is lit, it indicates a working 100 MB Ethernet
connection (100 MB network, only).
