Module IP
This is where you can change it from the factory default or DHCP assigned to one that better suits your network if required. Be aware that once changed, you may not be able to connect to it again straight away without first reconfiguring your computers network settings.
Module Host Name
Change to “lounge” or “Study” or "Bernard", whatever you like really.
UDP port for IR
The default is 65432. See "Advanced" help section "UDP Port" for more detail.
Module MAC
For info only, it is not possible to alter this.
Subnet Mask
The default is 255.255.255.0 and we recommend you leave it set at this. The only time this should really altered is if you have more than 255 devices on you local network.
Gateway address
If the initial DHCP was successful this is usually set to the IP address of your router, and can be manually entered if required.
DNS Server 1 & DSN Server 2.
The Domain Name Servers will usually have auto configured with the initial DHCP and can be edited if required.
Target IP
This should automatically be assigned and can be manually altered if required.
Computer IP 
Should be automatically set to the IP address of the computer you are using. Only important if you are using a receiver module for learning IR codes for use with other models of KIRA.
Enable LED flash
Recommended to leave on (it will only flash if there is a problem) unless you are port-forwarding to modules on remote networks.
Save and reboot
If anything has been altered you will need to reboot the module to make the changes permanent.
