by | Dec 20, 2020

VEN with 2 separate VEN IDs operating individually with cellular backhaul

Twin VEN

Relay 1 – Provide notice of Pending Event to either VEN ID.
Relay 2 – Moderate Signal VEN 1.
Relay 3 – High Signal VEN 1.
Relay 4 – On indicates DRAS connection (Reserved)
Relay 5 – Pre-Event. Adjustable 60 minutes prior to Event VEN 1.
Relay 6 – Moderate Signal VEN 2.
Relay 7 – High Signal VEN 2.
Relay 8 – Pre-Event. Adjustable 60 minutes prior to Event VEN 2.


Cellular Service – The GRIDlink CE Hybrid provides the 4G cellular service in an Industrial Cisco Class router. This will be configured to ping the Internet on the LAN and automatically failover to cell on loss of connection to the VTN

Router Capabilities – The router capabilities provide a firewall within the LAN that will prevent additional cyber protection from outside hackers but also protection locally within the network from unauthorized users.

Single LAN IP – Additionally, there is only one IP address required from IT for both VENs to operate on the LAN. This is important in highly restricted networks. The CE will create a sub-network for all devices attached like the GRIDlink VT-MIPM 135 ADR, BACnet converters or Modbus meters. GRIDlink 135 will accept up to 4 meter inputs in any combination of TCP, RS485 or 2 wire KYZ and provide Open ADR Usage Reports.

Industrial RTU – GRIDlink VT-MIPM 135 ADR provides the computational capabilities with 8 onboard relay outputs. The 135 will process the Events from both VEN accounts and send to the relays accordingly.
