REMOTE DIRECT COMMUNICATIONS
Pin 1: |
| Not Used |
Pin 2: | LBW | Output signal from UPS (RS232 levels) |
|
| High signal (+3 to +12 volts)= Low |
|
| Battery Warning |
Pin 3: | UPS Shutdown | Input signal to UPS, Shuts down |
|
| UPS (RS232 levels) |
|
| High signal (+3 to +12 volts) = UPS OFF |
Pin 4: | AC Fail NO. | Output signal from UPS, open |
|
| collector, High impedance = AC OK |
|
| Low impedance to ground = AC Failed |
Pin 5: | Ground | Common Return |
Pin 6: | Low Battery Warning | Output signal from UPS, open |
|
| collector |
|
| High impedance = OK |
|
| Low impedance to ground = Low |
| Battery Warning | |
Pin 7: | AC Fail NC | Output signal from UPS, open |
|
| collector High impedance = AC Failed |
|
| Low impedance to ground = AC OK |
Pin 8: | AC Fail Logic Signal | Output signal from UPS, logic level |
|
| Logic High (+3 to +12 volts) = |
|
| AC failed |
|
| Logic Low (0 volts) = AC OK |
Pin 9: | Remote Shutdown | Input signal to UPS, pulled to 5 |
|
| VDC through 10 K ohms |
|
| >2.4 VDC = Normal output |
|
| <0.8 VDC = Output off |
