DeviceMaster LEDs

The DeviceMaster has network and port LEDs to indicate status. This subsection discusses:
•

TX/RX LEDs

•

Network and Device LEDs

TX/RX LEDs
This subsection discusses RX and TX LEDs on the DeviceMaster 4-port.
Note: DeviceMaster DIN rail models do not have RX/TX 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.

• 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).
• 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.
• If the LINK (green) LED is lit, it indicates a working Ethernet connection.
• If the ACT (yellow) LED flashes, it indicates network activity.
