Additional UPS Features

Pin Out

As shown in Table 2, Pins 1 and 2 operate in two modes: Basic Alarms
mode and Serial Data mode. Basic Alarms mode has AC fail alarm and
output shutdown. Serial Data mode is UPS Code II compliant.
The system always starts in Basic Alarms mode. When serial data is
received at Pin 1, the function of Pin 1 and Pin 2 changes to Serial Data
mode.
If serial data has not been received before going to battery power, serial
communication is disabled until AC input power returns.
