11.2. Lost/Forgotten IP Address
The Battery Control Panel is resolvable using mDNS via a compatible computer. Refer to
Depending on the network interface used on the PC, this process may not work due
to differing security and IP configurations. If the only IP discovered is the IP of the
PC, the network interface is not suitable and another one will need to be used. This
issue is most common with USB to Ethernet dongles.
11.2.1. Wireshark (Windows/Linux)
1. Download/install Wireshark on a PC (
)
2. Connect the PC directly to the Ethernet port on the device
3. Start a Wireshark capture on the network interface connected to the device
4. In the 'filter' field, enter in
arp.isgratuitous
and press enter
5. Either reboot the device, or unplug/plug the Ethernet cable
6. The device should send a 'Gratuitous ARP' on the Ethernet network. In Wireshark the 'Info' field
looks like:
Gratuitous ARP for <IP> (Request)
where the
<IP>
is the address for the device
7. Once that is complete, update the PC network settings to match the device and connect the UI to
re-configure
11.2.2. Netdiscover (Linux only)
1. Install
netdiscover
on a PC (on Debian based systems use:
sudo apt install netdiscover
)
2. Connect the PC directly to the Ethernet port on the device
3. Run
sudo netdiscover -i <interface> -p
where
<interface>
is the network interface connected to the
device
4. Either reboot the device, or unplug/plug the Ethernet cable
5. The device address and MAC will show up in
netdiscover
once an ARP packet is sent
6. Once that is complete, update the PC network settings to match the device and connect the UI to
re-configure
