Помогите с распайкой интерфейсного кабеля UPS MINUTEMAN ALLIANCE Series a750/2 (MINUTEMAN a750/2)
В документации к UPS сказано: (но я мало чего понял, может кто подскажет какой провод куда для com порта)
COMMUNICATIONS PORT
The communications port on the back of the UPS (DB9 Female Connector labeled "Signal") can be
connected by a cable to a computer to provide the UPS monitoring capability described above.
Following are the pin connections of this connector.
UPS DB9 PIN OUT
PIN 1 N.C.
PIN 2 UPS simulates a relay closing (open collector transistor) between Pins 2 and 4
when it switches to Inverter mode.
PIN 3 Not used
PIN 4 Common ground return (for Pins 2, 5, 6 and 8).
PIN 5 UPS simulates a relay closing (open collector transistor) between Pins 5 and 4
at low battery warning.
PIN 6 User sends a RS232 high level (9-12VDC) to turn off the UPS (works only
during Inverter operation). UPS returns to AC mode when commercial power is
restored.
PIN 7 Common with Pin 4.
PIN 8 A500 and larger units: When this pin is shorted to ground, UPS output turns off.
Output returns when commercial power is available and the short is removed.
On units smaller than the A500, this pin has no connection.
PIN 9 Reserved.
