Connect your RS485 and Modbus devices directly to the Zora-3 platform. The RS485 Module adds four dedicated RS485 ports to your Zora-3 Main Unit, letting you integrate battery monitors, tank sensors, generators, and other onboard systems that communicate over RS485 or NMEA 0183 — all feeding into a single, unified navigation platform.

Key Features
- Four independent RS485 ports — connect multiple onboard systems simultaneously without running out of inputs
- Two galvanically isolated port blocks — Ports 0 & 1 and Ports 2 & 3 are electrically separated from each other and from the main system, protecting against ground loops and interference
- NMEA 0183 compatible — wire directly to legacy marine instruments using standard D+/D− connections
- Selectable 120 Ω termination on each port — simple pin bridge lets you properly terminate the bus without extra components
- Robust ESD protection (±15 kV) — built to handle the electrical realities of a marine environment
- Data rates up to 4 Mbps — fast enough for any RS485 device on your boat
- Powered by the Main Unit — no additional power supply or wiring needed
- Stackable — add up to three RS485, RS232, or MESH modules to expand your Zora-3 system as your needs grow
- DIN rail mountable — clean, secure installation in your electronics panel
