Perimeter control switch


New member
Greetings! I have an RL-850 mower from friendly robotics that is missing the perimeter switch. I have searched every way I can think of and the only supply of these units I have found is in Ireland. They don't have an option to purchase on line form the states. So my question is; is there another unit I can use to substitute the OE PCS? An invisible pet fence or something similar. There's not a lot of info available about how this unit works... Thanks in advance.
