5. Serial port configuration
5.1 UART configuration
To connect the UPS to the UPSLink serial port, the serial port parameters of the UPSLink should
match exactly to that of the UPS attached. The serial port parameters are required to match this serial
communication. The parameters required for the serial communication are: baud rate, data bits, parity,
stop bits and flow control.

Baud rate
The valid baud rate for the UPSLink is as follows:
1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, and 230400
The factory default setting is 19200.
Data bits
Data bits can be between 7 bits and 8 bits. The factory default setting is 8 bits.
Parity
Parity can be none, even or odd. The factory default setting is none.
Stop bits
Stop bits can be between 1 bit and 2 bits. The factory default setting is 1 bit.
Flow control
Flow control can be none, software(Xon/Xoff) or hardware(RTS/CTS). The factory default setting is
none.
