Good morning, I also did some tests with the multimeter looking at your diagram and the board seems not to work, that is, the KC868 has v2. Using your tool to check and change the assignments of the inputs to the outputs, I don't know if it also shows the activation of the outputs, but every time I close and open the input, the RS485 adapter emits a signal and under the bar it shows me the last signal that arrived, so the inputs, so to speak, "work". Now I tried with the multimeter considering that I'm using only one 12 volt power supply for everything, so the grounds are equivalent! Here is the voltage between the +12 volts and the output, which according to your diagram should be negative, always remains at 6 volts without ever varying (I'm talking about an open circuit). I tried installing a classic relay that is powered by 12 volts and has a pilot input that can be set to receive either positive or negative inputs. Obviously, I set the input to negative and when I try to close the input, the result does n

Here is the way I'm testing the board, same relay power supply and kc868hav2, the output is connected to the already set relay input which must receive the negative according to your wiring diagram present in the forum, button connected to input 1 and the board is in default so in theory since it is in rising Edge in toogle output mode every time I close the button it should vary the output, this does not happen! the relay works because if I jumper the negative with the input it activates, I also tried with other inputs and other outputs nothing to do, this board just does not want to work! obviously when I am connected with the rs485 adapter through your software every time I press the button the software shows me hexadecimal codes so let's say that the input works, it is the set logic that is not working!
if you want use HAv2 output for relay, your relay need driver, HAv2 output only mA level, can't drive relay directly.
when short HAv2 INPUT with GND, it will feedback RS485 command. But INPUT not TOGGLE with OUTPUT directly.
INPUT feedback message to RS485, OUTPUT control by RS485 command.
if you want INPUT toggle OUTPUT directly, you can use any kincony controller. just set digital input toggle relay output by IFTTT.

This relay has an input that consumes very little power, so I also use them with open collector outputs on alarm control panels. What type of controller do I need? Do you have a link to the model I should get? I have two KC868 A16s and one KC868 AP. In any case, if I use a multimeter and place the negative lead on the output and the other lead on the positive of the 12-volt power supply, the potential difference should vary. I don't see this change!

I know the kc868 A16 board well and it's fantastic, I even use it for HTTP commands to manage security devices like AI cameras by running Arm/Disarm and activating relays based on AI rules, but that's not the point. What I want to understand is whether the kc868 v2 board can also work "stand-alone," meaning that the input drives its output. Then, using the RS485 circuit, I can import the command by creating the HEX code on the RS485 command via the IFFFT configuration panel. This is all clear to me! I also figured out how to send commands via 2 kc868s using TCP/UDP connectivity, and it's very cool. I still need to understand this aspect of the RS485 expansion board!

If I tried the kc868 a16v3 with your latest firmware version, is the aforementioned board able to set the inputs of the kc868 ha v2 to make the outputs communicate?

sure, it's ok, download KCS v3 firmware, protocol webpage: set RS485 use for HAv2 protocol. so that HAv2 digital input can toggle with KC868-A16v3 output directly.
