Why does my Honeywell IP Access Controller panel not communicate via Ethernet?
M

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.

If the panel address is unknown, you have two options:
1. Set DIP switch 4 on the MPA2C3 panel to ON to default the IP address to 192.168.1.150.
2. Connect to the panel through the USB port using a Type-A USB to Type-C USB cable and the USB driver. The default USB Ethernet IP address is 192.168.2.150.

If the panel powers up but does not respond to communication, card reads, or input activation, ensure that the Address DIP switches are set to the correct values. To do this, turn off the power (including the battery), change the settings, and then re-apply the power.
