Connecting to different IP address ranges on home network

The address range on my network is 192,168.2.2-192.168.2.254, gateway
192.168.2.1, subnet 255.255.255.0.
I have just purchased a pair of HDMI extenders (TX/RX) that I have
discovered are hard-coded to 192.168.0.0 addresses. 
Is it possible to these devices to communicate to each other over my
network? At the present they are not.
Googling suggests that the answer might reside in changing the subnet
but I get lost as soon as they start attempting to explain binary
numbers and I haven't found any practical examples. 
Many thanks for any help/advice.
