Not quite related, but I just found out that Microtik(linux) has built in drivers for common Arduino serial chips. I setup an Arduino to monitor 4 different voltages at our solar site. Our NMS just SSHs to the microtik(special login) to pull the average voltages and graph them. I was happy to not add any more equipment other than the power sipping Arduino.

I have a server I que or add each thing I want to monitor or review. Temps, Humidity power levels or presence of are the main ones.

They sell an adapter cable for about $200 It adapts it to USB. The program that you use to talk to it makes reference to modbus. The data port has 4 pins. RJ-10 4p4c connector. +5 with enough current to light an incandescent light bulb. +5 low current +5 low current Ground This sounds like USB host to me. One of my sons think it is RS-485 I don’t think USB would be happy on a RJ-10 and utp wire. Maybe it would. Maybe I am just buying a piece of wire with two connectors on the ends. The controller it plugs into is $2000 so I don’t want to experiment on that. Be interesting to see the adapter cable when it gets here. See if there are any active components. I would have probably just wired it up to a USB and tried it if my son had not made the modbus/RS485 comment. Any guesses?
