The Priva Compass cabling consists of three completely separate communication networks. They are the
- IO bus
- Priva Network
- Office network
The I/O Bus is used internally to communicate between the controller and the I/O modules. This bus must be contained within the Compass enclosure. The I/O modules are identified by the order in which they are connected in the I/O network, so it is important not to change the order of the wiring.
The Priva Network is used to connect the Compass Controllers to the Priva Gateway. This is a standard Ethernet network, so you must follow Ethernet design rules when laying out this network between controllers. This network must be exclusive for Priva devices!
There are four ports on the CMX-34. You can use any one of these ports. These devices should be connected to a switch so that if the power is lost to one controller, the other controllers will continue to run.
If the ethernet cabling is to be run between buildings, use a fibre optic cable between the buildings or some other sort of lightning protection to protect your network.
The Compass network needs to be connected to Ethernet port 2 on the gateway.
The Office Network is your own network on your site. To access your gateway from any device on your site, you will need to connect your Office Network to Ethernet port 1 on the gateway. Depending on the gateway, this will be labelled as ETH1 or LAN1. By default, this port on the gateway is set up for DHCP, but you can change it to a static IP address from the Gateway setup page.
