DeviceMaster 500 Hardware Installation Overview

The following steps provide an overview of the hardware installation. You can refer to the DeviceMaster 500 Installation and Configuration Guide (Rev A) for detailed hardware installation procedures for your model or check for the web for a later version.


If you plan on using an NS-Link device driver, make sure that you do not connect RS-422/485 devices until the appropriate port interface type has been configured in the driver. The NS-Link default serial port setting is RS-232.

  1. Record the MAC address, model number, and serial number of the DeviceMaster 500.

  2. If necessary, mount the DeviceMaster 500.

  3. Connect the DeviceMaster 500 to the same Ethernet network segment as the host PC using a standard network cable.

  4. Apply power to the DeviceMaster 500 by connecting the AC power adapter to the DeviceMaster 500, the appropriate power cord for your location to the power adapter, and plugging the power cord into a power source.

  5. Verify that the Status or PWR LED has completed the boot cycle and network connection for the DeviceMaster 500 is functioning properly using the following table.


    Status or PWR

    4-port model has a PWR LED on the reverse side from the serial connectors.

    If lit, the Status or PWR LED indicates the DeviceMaster 500 has power and completed the boot cycle.

    The Status or PWR 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 30 seconds.

    Link Act


    If the Link/Act or LINK ACT LED is lit, it indicates a working Ethernet connection.


    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.


    1-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 500, 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 500 IP address.
