I have been running a Smart-UPS RT 3000 VA using nut successfully over
the 940-0095B cable for a couple of years.
I have just received a second unit, but it is slightly different in 3
ways that I have found so far.
1. It's a Smart-UPS RT 3000 XL
2. The 940-0095B cable now uses an RJ45 connector at the UPS end.
3. It now requires a baud rate of 9600 instead of the 2400 used previously.
Can anyone tell me if modifying drivers/apcsmart.c
void upsdrv_initups(void)
{
char *cable;
upsfd = ser_open(device_path);
ser_set_speed(upsfd, device_path, B2400);
to
void upsdrv_initups(void)
{
char *cable;
upsfd = ser_open(device_path);
ser_set_speed(upsfd, device_path, B9600);
all that is required in order to get nut to talk to it, or will other
things need changing?
Regards,
Richard

I can check for automating this detection but I need a driver debug output to validate it first. can you send me the result of: /path/to/apcsmart -DDD -a <upsname> cheers, Arnaud -- Linux / Unix Expert R&D - Eaton - http://www.eaton.com/mgeops Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org/ Debian Developer - http://www.debian.org Free Software Developer - http://arnaud.quette.free.fr/ -------------- next part -------------- An HTML attachment was scrubbed...
