702 DB9 Port Pin Functions
The table below explains the functions of the pins on the FERRUPS’ DB9 port. This port is on the FERRUPS’ back panel. The functions of pins 1 and 2 change depending on the communication mode. When you receive the UPS, it is set up for RS232 mode. However, if you want to use the alternate functions of pins 1 and 2, you can change the mode by following the steps on the next page.
