Facility connections to ECS

You can connect your facility to the ECS using the RJ45 in the demarcation box (on page 66) or cables that are hard-wired through the connection portals on the cargo end of the HP POD 20c. The system uses Modbus TCP/IP for communication.

Connecting to the ECS

To connect the network to the ECS control panel, route an Ethernet cable to the appropriate RJ45 connector inside the HP POD 20c demarcation box (on page 66).
