Initiating hyperterminal/putty to connect and open the ups serial port ,it opens ,however when i begin to test the connection by 

entering  "SHIFT + Y"  ,well nothing happens . I expected to receive "SM".

Av just bought anumber of this UPS and i wanted to verify all these before i install them for use.

Does anyone knows the trick???   for SMT1500RM2U series  

I have manage to do the SUA1500I series successfully.

SMT is a different UPS type and does not support this procedure. It shouldn't need to be done and if you replace the batteries, the runtime should update automatically. The reason that some users reset the battery constant on older models is because it did not update automatically on its own. The new UPSs have a different design and this shouldn't be required, nevermind that you cannot do this process.
