MikroTik

Hello, I have a monitoring problem between RB960PGS and UPS APC BX1600MI-GR. The router sees the UPS and shows its parameters, but in the Mikrotik logs it constantly spits out UPS Power on and then Power off for a minute. I think that the problem is something in the communication, because the USB of UPS is 1.10, and of RB it is 2.0. I read in the forum, the communication problem was solved with a simple Usb Hub 2.0, I bought one, but the result is the same. I wanted to have monitoring on it, and that was one of my important requirements when buying the UPS, but that's exactly what didn't work as it should.
