    Can someone please provide a pinout on the Smart UPS 750 9 pin D-Sub connector?  I am specifically interested in whether is has a contact closure for "on batteries".....   I can't find any info googling this, nor in the documentation. 

    My thanks in advance,

    Hi Bruce,

    If you're Smart-UPS 750 begins with SU or SUA in the actual model SKU - which means it has a DB-9 style serial port (as opposed to RJ-45), then here are some resources for you:

    Thank you very much.  Is there a 1200 or 1500 VA model with an identical DB-9 connection (100% interface compatible)?

    Hello Bruce,

    You would want to look at older SmartUPS that begins with SU or SUA on its model number.
