Grounding

To ground the OMNIGND, connect a wire from a properly grounded source (eg: the B92500 GroundHog from Botron) to either a ring terminal or banana jack of the Ground Hub located on the bottom of the OMNIGND. This will ground the entire Ground Hub.

  • When the OMNIGND has been properly grounded, the rest of the open ports of the Ground Hub may be used for grounding other devices.
  • It is recommended that a ground wire is used to connect the grounding block on the bottom of the OMNIGND to the far left monitoring port (Port H) on the top of the OMNIGND. By factory default this Port H is named OMNIGND.
  • When this configuration is done properly, the OMNIGND will continuously verify the built-in Ground Hub to ensure that it is properly grounded.

Connecting Devices

To monitor equipment, connect a ground wire from one of the available monitoring ports, located on the top of the OMNIGND, to a point of ground on the desired device.

Note – The name and description for the port may be changed to reflect the device being monitored.

Getting Online

The OMNIGND is a network accessible device. To connect the OMNIGND to your local area network (LAN), connect an Ethernet cable from your network appliance (router, switch, PC ethernet port) to the Ethernet jack located on the top of the OMNIGND. The OMNIGND will have DHCP enabled by default. Advanced network settings may be configured. See Network section.

Mounting

Once your OMNIGND is connected and your equipment setup is complete, find an optimal place to mount the device in an area where it can be easily accessed and/or viewed.

Configuring the OMNIGND

The OMNIGND comes with a WebUI interface called OMNIManager. This interface allows you to configure and customize the OMNIGND to meet your application needs.

Locating the OMNIGND on the Network

  • Finding the IP address on your OMNIGND
    • On the OMNIGND press the Select Button until you reach the TCP Information Screen (one press from the Status Screen).
    • Locate the IP Address on the screen. (ex.: IP: 192.168.1.217)
  • Open an internet browser on a computer, tablet or phone connected to the same network as the OMNIGND.
    • Type in the IP address of the OMNIGND in your browser’s address bar.

Getting familiar with OMNIManager WebUI
