Could somebody please help me get this one to work using the close 
contact information.
I can not get it to detect off line

OpenSuse 11.0 NUT 2.2.2
         driver = genericups
         port = /dev/ttyS1
         mfr = "Cyberpower"
         model = "PR1500LCDRTXL2U"
         desc = "Cyberpower PR1500LCDRTXL2U - Serial/contact"
         upstype = 7
         LB = DCD
         OL = CTS
         SD = DTR
         CP = RTS

Vendor information:
The secondary port pin out is as follows.

I.            Initialization:
Pull Pin(7) High.
II.          Monitoring(UPS Status Detection):
Pin(1): 	High means battery capacity is normal. Low means 'Low Battery'.
Pin(8):	High means Utility Power is normal. Low means 'Power Failure'.
III.        Shutdown UPS:
Pin(4): 	High 10-15 sec to 'Shutdown' UPS.

Pin 1 and 8 are open collectors; the pull high pin is 7. When using the contact closure port, pull pin 7 high.
Pin 7 can support standard RS232 voltage up to 15V.
If the high voltage comes from pin 7, and pin 7 is 5V, the high level is 5V; if pin 7 is 15V, the high voltage is 15V.
When using Shutdown function (Pin 4), the level should be 15V(RS232 level)
