Supervisory controller
AeroNode 232
Two RS-485 trunks plus two RS-232 ports.
The same controller with a mixed serial configuration. COM3 and COM4 are isolated RS-485 trunks for BACnet MS/TP or Metasys N2. COM1 and COM2 are RS-232 ports for point-to-point serial equipment through Aero's RS-232 drivers. Everything else matches the AeroNode 485.
Key features
- No point or device licensing; no annual SMA
- BACnet/IP, BACnet MS/TP and Metasys N2 (N2 Open) drivers, each in its own supervised process
- Program sheets with PID, formula and reusable macros; schedules; trending; alarms
- HTML5 AeroView served over HTTPS; nothing to install
- Outbound-only encrypted connection to AeroServer and AeroConnect
- Signed firmware with automatic rollback
