    Hi, I bought a used SUA1500RM2U that came with the AP9617 management card.  I read in the manual that i need a APC serial cable to connect to PC to reset the AP9617.  I bought a new cable off ebay APC 940-0020C.  

    I hooked up the serial and set my only serial port to 2400-8-N-1-N COM1 in windows

    I used putty and set it to the same serial speed above.

    pressed enter in putty, nothing on the screen.

    tried different speeds 9600-8-N-1-N

    reconnect with putty, no output on screen.

    then i tried to do the reset procedure anyways.

    pressed and released the reset button on AP9617 card,  LED flash quickly, I pressed and released the reset button again.

    i then pressed my enter button continuously until the LED stop flashing and remained steady pressed some more.

    Still no prompt on my PUTTY.

    I then removed the AP9617 card out of the UPS think it may be defective.

    try connecting serial with putty again, nothing on screen.

    then i removed the battery from the AP9617 and left it alone for a week, hoping it would lose it settings, but still nothing.

    any help is appreciated, or do i have a defective serial port an/or AP9617?

    BTW, when I plug the UPS using the USB cable to my UNRAID server, it reads everything about the UPS no problem.

    I just want to try to get the AP9617 card working

    Thanks

    I believe on that UPS using USB disables the serial port. To re-enable the serial port, unplug the UPS and its battery, wait for a few seconds for the fan to stop spinning and the lights to go out, and then re-assemble the unit.

    Hi,

    You need smart signalling cable 940-0024. Cable 940-0020 is simple signalling meaning it is one way communications. From UPS to computer. The smart signalling cable is two way.
