UPS

"UPS" can set up UPS (Uninterruptible Power Supply).
Currently, the system only supports and communicates with smart-UPS of APC (American Power
Conversion Corp.) UPS. Please review the details from the website: http://www.apc.com/.
First, connect the system and APC UPS via RS-232 for communication. Then set up the shutdown values
when power is failed. UPS in other companies can work well, but they have no such communication
feature.
