JohnMo Posted July 18, 2024 Posted July 18, 2024 I need to run a cable about 6m from the ASHP Modbus outlet to a controller. Anyone know what cable I need, and where I can buy by the metre?
SteamyTea Posted July 18, 2024 Posted July 18, 2024 Uses shielded twisted pair I seem to remember. Though I think a lot of people use converters then CATx. 1
pudding Posted July 18, 2024 Posted July 18, 2024 Just a pair from a CAT5/6 cable? I've using a pair in a CAT6 cable from an Eastron power meter to my PV inverter to carry a modbus signal. 1
dnb Posted July 18, 2024 Posted July 18, 2024 I have an rs485 based modbus connection working on cat5e for my solar inverter data. No problems so far.
