What are the port settings (baud rate, ect) to talk to the serial port on the SUA2200RM2U? I'm not finding that in the User Manual (990-1352A 11/2003).
If you connect to the UPS serial port directly with your PC and a terminal program, it requires 2400 baud, 8 data bits, parity none, 1 stop bits, flow control none.
This can change when you have an accessory installed or connected to the UPS or you're using PowerChute software. If this applies, let us know what is installed or configured for any other possibilities.
