Connecting the Sentinel to your Network

Your Sentinel is a network ready device. DHCP is enabled by default. Advanced network settings can be configured in the ELITE WebUI.

Before Proceeding we recommend this section to be performed by a qualified IT or Network Administrator.

Direct LAN

(to a PC or MAC)

  1. Plug the supplied RJ45 cable into the ethernet port on the back of the Sentinel V2.
  2. Connect the opposite end of the RJ45 cable into your computer’s ethernet port.
  3. Confirm a successful connection by verifying the IP address in the TCP screen of the Sentinel Display.

Please note, on laptops you may have to disconnect/disable WiFi connection.

If your IP does not display, please power cycle the Sentinel V2. (See Troubleshooting)

LAN or WAN Network

  1. Plug the supplied RJ45 cable into the ethernet port on the back of the Sentinel V2.
  2. Connect the opposite end of the RJ45 cable into your ethernet terminal, router or switch.

DHCP

  • The Sentinel will automatically obtain an IP address from the network router.
  • Confirm a successful connection by verifying the IP address in the TCP screen of the Sentinel Display.

Reserved IP

You will need the Sentinel V2’s MAC address for this networking environment. This can be found in the TCP screen on the Sentinel.

  • In your router application assign a permanent IP address to the MAC address of the Sentinel.

Static IP

Static IP can be configured in the ELITE WebUI once your Sentinel V2 is on the network and accessible.

  • A Static IP makes it easier to work remotely using a Virtual Private Network (VPN) or other remote access programs.

Hardware Settings and Configuration

All of your Sentinel V2 settings and configuration are done from within the ELITE WebUI WebApp. Once your device is connected to the network you can start customizing your device.

Accessing the ELITE WebUI

Finding the IP address on your Sentinel.

  • Press the menu button located on the side of the Sentinel V2. 
  • Cycle to the TCP info screen that contains your device’s network information. 
  • Locate the IP Address on the screen. (ex.: IP: 192.168.1.217)
    • Open an internet browser on a PC/Mac, tablet or phone connected to the same network as the Sentinel.
  • Type in the IP address of the Sentinel in your browser’s URL bar.

If your IP does not display, please power cycle the Sentinel V2.

Please refer to the supplemental calibration document for the calibration process. When calibration is completed successfully the Sentinel will digitally sign a new calibration cert.

Network

The Network Page displays the network information for the Sentinel V2. Here you can enable or disable DHCP.

  •  Enable/Disable DHCP
    • By disabling DHCP, you may change the IP Address, Gateway, Subnet Mask, Primary DNS, and Secondary DNS. Disabling DHCP will assign a static IP.
  • The MAC address and hostname are non-changeable
    • The MAC Address is the unique hardware identifier for the networkable device, typically used in static IP and reserved IP environments.
    • The Host Name may be used in an internet browser connected to the same network as the Sentinel V2 to get to the WebApp.
  • The IP Address, Gateway, Subnet Mask, Primary DNS, and Secondary DNS must be in the format: XXX.XXX.XXX.XXX
  • To save any changes to the Network, press the save button. The Unit will then refresh its LCD screen to show the TCP Info screen before returning to the Home Screen.

Factory Default

The Factory Default page may be used to reset the Sentinel back to factory default values for the following:

  • Table of Content
  • Hardware Setting
  • Network Setting
  • Update

Choose one of the available selections to be reset to its factory default values by the corresponding box next to it.

  • After you have made your selections; press the Update button to begin the reset process.
    • Please note that any values reset on a given tab will affect corresponding values across the ELITE WebUI Interface
  •  Resetting Table of Contents is a full factory refresh.
    • When the reset command is sent, the Unit will power off, and reboot with factory default settings.
    • Please note the ELITE WebUI Interface will disconnect with the TCP website as it powers down. When the Unit reboots, the TCP website will need to be refreshed to establish a connection with the Unit again.
