Troubleshooting Notes

Cannot access the web interface

Check the following:

  • PC Ethernet adapter is in the 192.168.2.xxx range.

  • Ethernet cable is connected to ETH2.

  • Browser is using http://192.168.2.101/.

  • Web access is not blocked by IP filtering.

  • Use the USB method to read the current IP address if required.

Login is locked

If the wrong password is entered three times, wait 10 minutes before trying again.

Network changes are not active

Reboot the Multigateway after changing IP or DHCP settings.

BACnet is not working

Check that only one BACnet mode is enabled:

  • BACnet IP, or

  • BACnet MSTP

Both cannot be active at the same time.

Modbus communication is not confirmed

Go to Stats and confirm that CANbus TX and CANbus RX counters are increasing.

Internal Notes

  • USB configuration requires node_info.txt in the root directory.

  • USB firmware updates require the file name mgtw.bin.

  • Firmware update by web interface can use other file names.

  • Use caution with factory reset commands, as device data will be lost.

  • Confirm NTP and time zone settings after commissioning.
