Re: [Nut-upsuser] SU2200RTXLCD2U and protocol 4006

Hi Larry and thanks for your answer. I will have a look. Tripplite will send you the pdf of the protocol if you communicate them the UPS serial number. Ambrogio On Mon, Jul 3, 2017 at 2:16 PM Charles Lepple wrote: > On Jul 3, 2017, at 12:48 PM, Ambrogio Coletti wrote: > > >

Thank you for your answer. I will try to investigate the possibility that the Tripplite serial cable has a different pinout than a standard RS-232 serial cable. I wouldn't use the NUT at this point because I don't think I will be able to write a software update to adapt the NUT to my needs. My

I don't have the Tripp-Lite model that you have, however the NUT HCL http://networkupstools.org/stable-hcl.html suggests that the SU2200RTXLCD2U ought to work via USB. Tripp-Lite sometimes uses proprietary serial cables, so you may need to hunt down a pinout for the serial cable this unit
