Electrical Domains
Certus contains separate electrically isolated domains. Each domain is isolated from the others to minimise noise injection and avoid ground loops. Where possible, this isolation should be preserved by externally connected devices. We recommend connecting the enclosure to your vehicle ground where possible for the best electrical noise performance.
| Domain Name | Affected Components and Ports |
|---|---|
| Chassis | Enclosure |
| Power | Power Supply |
| Serial | Primary port, Auxiliary port |
| GPIO | GPIO 1 port, GPIO 2 port, 1PPS port |
| Ethernet | Ethernet port |
