Why does my Honeywell IP Access Controller panel not communicate via Ethernet?
- Mmary36Aug 8, 2025
Communication via the Ethernet port is only available when the panel is set as Primary. To enable Ethernet communication, power off the panel (including the battery), set Bit 3 of DIP switch 1 to ON, and then reapply power. Note: If the panel is not normally a Primary on a Multidrop communication bus, disconnect the Host RS-485 connection J7/8 while Bit 3 of DIP switch 1 is ON. After the Ethernet session, power off the panel again (including the battery), revert the switch setting, reconnect the Host RS-485 terminal block, and reapply power.
