Hi.

I put into practice the article UPS for Linux by Thomas Chung and
installed Bulldog UPS from Belkin for my F6C320-SER UPS.

I am still wondering at the result, It does not look right.
The PC does not have a modem and the UPS is plugged into the
Serial Port. I built a Null Modem serial cable to connect
the UPS to the serial port.

If I select /dev/ttyS0, the Utility Power Status and the Battery
Status say "Unknown"

If I select /dev/ttyS1 to /dev/ttyS3, then the Utility Power Status
and the Battery Status say "Normal".

I know this is not normal but I wonder what am I missing?
Should I uncross the wires on the serial cable?

I tested the cable of my APC UPS on my other computer
and they are straight-thru.

I think maybe I have not setup the serial port properly, How can I test
for it?

If I do   stty -F /dev/ttyS0, I get
speed 9600 baud ; line=0;
-brkint -imaxbel

If I repeat it for /dev/ttyS1, I get
stty: /dev/ttyS1: Input/Output Error

(how do I setup minicom to capture /dev/ttyS0? I read the
manual but it assumes I am using a modem and AT commands.)


In any case, if I disconnect the power cord, I do not get
any shutdown notice.

Thanks for whatever help you can provide.

Are you using the Belkin driver for Linux ? It says it is for Redhat 5.2 or something but seems to run OK on FC1. http://web.belkin.com/support/download/download.asp?download=F6C32

Now it doesn't seem to list a Linux driver for your particular UPS but
I'd have a go with the Linux one as it appears to be common for several
serial Belkin's.  Other than that (and maybe as a better choice) you
could take a look at NUT at http://www.networkupstools.org/  The driver
there for the Belkin UPS seems to work OK too with FC1.  Check out
http://quasar.mathstat.uottawa.ca/~selinger/ups/ for a system V
start/stop program for Belkin-supplied driver and details about the NUT
serial driver for the Belkin UPS's.

I just use the serial cable that came with the UPS and it works fine.
Are you using a serial port connector that is directly on the MB of your
computer or one of those ones that connect with a little cable?  I there
there are a couple of versions of the wiring for the cable type (I had
to rewire mine).

In retrospect, Belkin would not be my first choice for a UPS under
Linux.  MDG seems to have good Linux support.

Hi Mike
I lost the cable for the UPS, therefore I had to roll my own.
I am using the serial port connector that is directly on the MB of my
computer. I am going to check NUT and the other addresses.

What is the pinout of your cable?

Thanks!

Javier

Hi Javier,

I'm not at the same site as the machine with the Belkin UPS but I would guess that it is just a standard serial cable. The UPS on it is a F6C120-UNV (serial and usb) probably different from yours I think.

You could check out this document about the serial and usb connections for Belkin http://web.belkin.com/support/download/files/F6CXXX_ups.pdf In there it says:

7.1 Interface Kits
Each interface kit includes a special interface cable which is required
to convert status signals from the UPS into signals that the individual
operating system can recognize. The interface cable must be connected
to the REMOTE PORT on the UPS. The other side of the
interface cable can be either connected to COM 1 or COM 2 of your
PC. For other installation instructions and features, please refer to
the READ.ME file.
Caution: Use only factory supplied or authorized UPS monitoring cable!

I seem to recall amonst the stuff for NUT there was instructions for making cables for different UPS's but it has been a while since I've looked at it.
