1) устанавливая агент PBE 9.2 он определяет упс как smart 3000 RM (что по COM, что по USB), после установки см #3 рис1.
2) запускал терминал чтобы проверить как в инструкции:
In the Connect Using field of the “Connect To” dialog box, select the serial port that the UPS uses, and click OK.
In the “Port Settings” dialog box, ensure that the port settings are correct for Windows; Bits per second: 2400, Data bits: 8, Parity: None, Stop bits: 1.
When a blank screen is displayed, type an uppercase Y.
If the screen displays the letters, SM (Smart Mode), there is no problem with the serial communications link.
If SM is not displayed, type an uppercase A. If the screen displays OK, the UPS can receive signals, but it cannot send them. Possible causes of issues are:
The serial cable may be faulty. Replace the serial cable.
The computer’s serial port may be unable to receive signals because of an interrupt conflict or a malfunctioning in the port. Try using a different computer.
The UPS may be faulty. Try using a different UPS.
ответил в терминале "SM" - значит кабель рабочий.
