DeviceMaster RTS Hardware Installation Overview

The following steps provide an overview of the hardware installation. You can refer to the DeviceMaster Installation and Configuration Guide (Rev F) for detailed hardware installation procedures for your model.

  1. Record the MAC address, model number, and serial number of the DeviceMaster RTS.

  2. If necessary, mount the DeviceMaster RTS.

    If needed, a Rack Mount Shelf Installation document is available.

  3. Connect the DeviceMaster RTS to the same Ethernet network segment as the host PC using a standard network cable.

  4. Apply power to the DeviceMaster RTS.

    • Power adapter: Connect the AC power adapter to the DeviceMaster RTS, the appropriate power cord for your location to the power adapter, and plug the power cord into a power source.

    • Power cord: Connect the appropriate power cord for your location to the DeviceMaster RTS and then connect it to a power source.

  5. Verify that the Status LED has completed the boot cycle and network connection for the DeviceMaster RTS is functioning properly using the following table.


    Status or PWR

    4/8/16/32-port models have a PWR LED on the reverse side from the serial connectors.

    If lit, the Status or PWR LED indicates the DeviceMaster RTS has power and completed the boot cycle.

    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/Act or LNK ACT LED is lit, it indicates a working Ethernet connection.


    Available on 1-port models and 16/32-port models with internal power supply.

    If the Duplex LED is lit, it indicates full-duplex activity.


    Available on the 4/8/16-port models with external power supplies.

    If the COL LED is lit, there is a network collision.


    If the 100 LED is lit, it indicates a working 100 MB Ethernet connection (100 MB network, only). If the LED is not lit, it indicates a 10 MB Ethernet connection.


    4/8/16/32-Port Models

    1/2-Port 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 RTS, 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 or minicom to open a port or ports if you want to test a port or ports.

    • 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

  6. Configure the DeviceMaster RTS IP address.
