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 following products:
• DB9: Comtrol device 4-port (panel mount) and 8-port models and the DeviceMaster Serial Hub 16-port.
• RJ45: DeviceMaster RTS 16-port and 32-port models and the DeviceMaster PRO 16-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. You can use Test
Terminal to open a port or ports if you want to test a port or ports
Page 154).
• 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, SocketServer is running or after driver
installation, that the NS-Link driver loads. 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).
