by Hello!
I would like to get my OptiUPS 650E working with Linux
somehow. I've read the UPS Howto as well as the genpower.docs, but
everything seems so far off from my situation - especially given the
fact that my Viewsonic documentation says it supports the "Dumb UPS signalling
standard" (!!) to allow most UPS software to run in dumb mode.
Has anyone gotten a Viewsonic/Optiquest UPS running with Linux
yet?
FYI: Viewsonic Documentation Pin Assignment: ------------- PIN 1 Remote Turn-On Note: 2. Pin 4 and pin 7 should only be connected to ground. --------------------------------------------------------------------------- --

PIN 2 UPS simulates a relay closing between pin 2 and pin 4 when
input power fails.
PIN 3 Not connected
PIN 4 Common for pin 2 and pin 5.
PIN 5 UPS simulates a relay closing between pin 5 and pin 4 when
the battery inside the UPS has less than 5 minutes backup
time left.
PIN 6 User sends a RS232 high level (5-15V) for 3 secs. This signal
will turn off the UPS until proper input voltage returns. It can
operate only if UPS is in battery mode. This pin is also used
as the RS232 receiver pin (RXD).
PIN 7 Common for pin 6 and pin 9.
PIN 8 Not connected
PIN 9 RS232 transmitter pin (TXD).
1. Pin 2 and pin 5 are open collector outputs which must be
pulled up to a common referenced supply, switch rating: +40 V, 0.15A
non-inductive.
My Note: I believe (RXD) and (TXD) (pins 6/9) are used for the
"smart" UPS communication.
