It is possible to connect powerlines with different data rates and brands as our devices use the HomePlug AV2/AV standard which makes any device compatible no matter the brand or data rates. For instance, you can connect a powerline 1300 with a powerline 1000 or 1200 as they have similar data rates. That is why, we strongly recommend not to connect a powerline 1300 with powerline 500 or 600 which have lower data rates as the maximum data rate is lower than the one of the powerline 1200. On the other hand, we also advise you against connecting a powerline 1300 with a powerline 2000 as the data rate of the powerline 2000 will be limited to the maximum data rate of the powerline 1300. In addition, a Powerline 1300 can be connected to powerlines 1300 of different brands but we cannot guarantee that it will work properly with powerlines 1300 from other brands, as there may be software differences.
