Remote Shutdown Via the DB-9 Connector

The PowerSure PSP can be shut down remotely by shorting Pins 5

and 6 or via Pins 4 and 5 of the DB-9 connector.

Shutdown Via Pins 5 & 6

When Pin 6 is shorted to Pin 5, the UPS output is shut off regardless

of what mode the UPS is operating in. The UPS cannot be started as

long as the pins are shorted. When the short is removed, the UPS out-

put can be enabled by pressing the ON/OFF/Alarm Silence button.

Shutdown Via Pins 4 & 5

While the UPS is operating on battery (with no battery test in

progress), a 5-12VDC signal for 2 seconds or longer is required to sig-

nal a shutdown. Signals for less than 2 seconds are ignored.

After Pin 4 receives the shutdown signal, a 2-minute shutdown timer

inside the UPS begins a countdown. The timer cannot be stopped. If

utility power returns during the 2-minute timer countdown, the shut-

down timer continues until the end of 2 minutes and then the UPS

turns off. The UPS must remain off for at least 10 seconds.

By default, autorestart is enabled so the UPS will restart after

10 seconds. If autorestart is disabled via MultiLink software, the UPS

remains off until a manual restart.

USB Interface Port

The PowerSure PSP has a USB interface port for communication that

will work with built-in Microsoft Power Manager software on the

user’s PC, if so equipped. It will provide UPS status and manages the

automatic, orderly shutdown of the computer. The UPS (USB) commu-

nications meets HID standard, version 1.11. All USB models are com-

patible with Microsoft Windows 2000, Windows XP and Mac OS 10.2

or later. All USB models ship with a 1.8m (6-ft.) USB cable.

Data Line Protection Connectors

Data line (1 input & 1 output) connectors are located on the rear of the

UPS and provide transient voltage surge suppression (TVSS) for

Phone/Fax/DSL/Internet/Modem devices.
