2. If the delay settings are the same for both IR1 and IR2, the IR2
code will be sent to both outputs 2 seconds after IR1.
3. The IR commands will also be transmitted immediately after
the battery charge falls below the critical load battery threshold.
This ensures that equipment will be shutdown properly if the
UPS’s load level is extremely high and the backup time would be
less than the selected IR output delay.
4. There is no IR output after the power is restored to the system.
To program IR output:
1. From the setup menu, turn the Menu Navigation Knob until
IR1 Setup is displayed. Push the Menu Navigation Knob to
select.
2. Turn the Menu Navigation Knob until IR1 Program is dis-
played.
3. The screen will display the message “READY TO SAMPLE
REMOTE”. Press the button on the remote.
4. If the signal was learned, then the screen will display the
message “IR1 SAMPLED” and advance to the “TEST IR” screen.
Press the navigation knob to test.
5.If the signal was not learned, the screen will display the mes-
sage “IR1 SAMPLE FAIL”, then it will return to the IR1 Program
screen. Repeat steps 3 and 4.
6.To program another IR device, from the Setup menu, turn the
Menu Navigation Knob until IR2 Setup is displayed. Follow
steps 3-5.
Advanced Operation
RS-232 Control with Open Protocol
The RS-232 serial interface can be used in the following ways:
1. Initial system setup. An installer can use a notebook comput-
er to set the variables within the Power Control software. Once
the setup is completed, the notebook computer can be discon-
nected. All settings are stored in the UPS.
2. Connection to a PC or Network: Functionality is very similar
to a standard UPS with a PC.
The UPS can provide continued power to maintain recording
capabilities of any number of devices in the event of a black out
or brown out. It is also capable of saving open documents and
shutting down the PC during extended power failures. This re-
quires a permanent RS232 connection to the PC and having the
Power Control software running in the background on the PC.
(Windows based OS only; Mac Energy Saver software compat-
ible)
3. Integration with sophisticated automation systems like AMX
and Crestron:
The serial communications command set and protocol is open
and is published later in this manual. This information can be
used by the automation system programmer for both UPS control
by the automation system and reporting of power events by the
UPS to the automation system.
