Yes, it's being output continuously. The only thing that is changing
is L1F0D part. We also monitor this UPS through USB cable, but it
connected to Windows 2003 server and according to SMX1500XLRT2U specs
it: "Supports simultaneous remote monitoring of UPS and site power
conditions via built-in USB and DB9 monitoring ports.".

Thank you.
