5. INTERFACE FEATURES
5.1 COMCONNECT (RS232) INTERFACE
Located at the back of the unit, the ComConnect is a plug-in interface port (9-pin, Sub-D, male)
which enables advanced communication between the UPS and the computer (interface kit
required).
The microprocessor controlled and galvanically isolated ComConnect sends information
concerning power levels and UPS condition to the computer or network interface.
In the event that batteries are near exhaustion, it sends commands for unattended controlled
shutdown of computer systems.
The ComConnect can also receive UPS shutdown signals from computers or network
interface.
When signals are sent to the computer, a written message can appear on the screen to inform
the user.
Monitored conditions include:
• mains voltage availability;
• discharge level of batteries;
• temperature of the batteries;
• interactive control- and diagnostic information for stand-alone and network systems.
Interface kits (cables and software) are available for most commonly used network operating
systems, including Novell, UNIX, VMS, Banyan Vines, Windows Platforms, Apple, 3COM, IBM
LANserver, IBM AS/400.
Remote servicing through a modem (external) is possible with GE Service Software.
We strongly recommend to use only original GE software products in combination with the
ComConnect interface port.
We only guarantee proper operation of original GE products.
The ComConnect cable should be shielded, connect the cable shield to the computer cabinet
only
