Network Planning
If a cellular router is being used to provide Internet connectivity, you can skip the Network Planning section of this document.
For installations relying on a corporate Local Area Network (LAN) for Internet access, it’s crucial to coordinate with the IT Manager in advance. Ensure that the GRIDlink ADR is permitted to function as a DHCP client on the network. To streamline this process, provide the IT department with a detailed request outlining the requirements. Refer to the "Letter to IT Manager" section in the User Manual for a sample request template.
IP Address (Static vs. DHCP)
GRIDlink VENs are preconfigured with the WAN port set to DHCP by default. If a static IP address is required for the installation, it is recommended to configure this on a known network at your office prior to arriving at the job site.
For detailed guidance, refer to the "Change DHCP to Static IP" section in the User Manual or contact Technical Support for step-by-step assistance.
GRIDview will make the installation easy
It is recommended to contact tech support and set up the GRIDview account. This will help with diagnosis and testing. Using the Subscriptions you can add the installer's phone number to receive alerts and test functionality before the VTN is set up. This way when the installer has successfully connected the GRIDlink, a text will be received confirming all is well. On installation day, bring a laptop and CAT5E cable to trouble shoot the network if necessary.
GRIDlink 6021 E Series with Onboard Cell
There are four lights on the cell modem that indicate status of the cell service and RS232. The signal LED blinking or on indicates that the antenna is connected and has signal. The WAN LED blinking or on indicates that the cellular connection is established. For the modem to have a cell connection, a SIM card will need to be installed. The SIM card is inserted on the thinner side of the cell modem next to the USB port.
Router Capabilities
The GRIDlink E Series features five 10/100 Ethernet ports, offering flexible connectivity options for network integration.
Port 5 (WAN): This port should connect to the facility's Local Area Network (LAN) with a pathway to the Internet. If a cell router is included, connect the WAN port of the E Series to the LAN2 port of the cell router. For failover setups, connect the WAN/LAN1 port to the facility's LAN. This is the only port requiring an IP address from the facility's network.
Ports 1 to 4 (LAN): These ports operate as a sub-network managed by the E Series' built-in DHCP server. Devices connected to these ports will receive a DHCP lease with IP addresses ranging from 10.27.1.10 to 10.27.1.50. These ports can be used for connecting devices such as Modbus meters, HMIs, or building management systems (BMS).
The E Series allows MAC-to-IP resolution configuration through its web interface (WEB UI), ensuring seamless integration and management of connected devices.
VT-mIPM 135 Series
The 135 Series has a MAC to IP resolution set in the E Series router and can be found at 10.27.27.15. If after several minutes with the power being supplied to the unit, the PWR light begins to blink, this may indicate that the 135 Series has lost its DHCP Lease. Please give the unit 5 minutes to regain connection. If the problem persists after the 5 minutes, please power cycle the entire unit. Check all connections are seated properly and power is being given to the cell modem/router.
Easy 3 Step Installation
Before drilling any enclosure penetrations, first place batteries in their desired position at the bottom of the enclosure to avoid interference. Do not attach wires.
1. Connect the Load
Gemini has 7 DPDT available relay outputs
| Relay No. | Terminal | VTN | Description | |
| 1 | Pending | 7 | Both | Beacon when either VTN is Pending |
| 2 | Moderate | 37 | 1 | Moderate Signal |
| 3 | High | 8 | 1 | High Signal |
| VTN | 38 | 1 | VTN 1 Parse Successful | |
| 5 | PreEvent | 9 | 1 | Configurable time before Event |
| 6 | Moderate | 39 | 2 | Moderate Signal |
| 7 | High | 10 | 2 | High Signal |
| 8 | PreEvent | 40 | 2 | VTN Parse Successful |
2. Connect to LAN
Connect Local Area Network to port 5 (WAN). The VENs will connect to their respective VTNs through this LAN. The E Series will ping Google 8.8.8.8 to establish the network has a valid Internet connection. Failure will initiate a fail-over to the cell connection and return once the Internet connection is re-established on the LAN. Install SIM card as shown.
3. UPS Battery Installation
Power down enclosure.
Two 12VDC batteries are shipped separately and should be installed, sitting freely on the bottom once the enclosure is mounted.
Battery terminal wires are labeled and are shipped with insulated Quick-Disconnect Terminals installed. Install the batteries and wire in series to attain the 24VDC enclosure power requirement. See diagram.
Power up – Ready to go!
