[Nut-upsuser] UPS Product additions to NUT HCL list for compatible Tripp Lite UPS systems
Hello Mr. Leppe, See the attached excel file that covers the current Tripp Lite HID compatible UPS systems. There is also an attached Word document covering the UPSC / UPSCMD / UPSRW information from the specific UPS systems. Let me know if this is adequate to get our additional HID compatible products added to the NUT HCL listing. Tripp Lite Eric K.

We have tested your latest NUT distributions against our HID USB compatible UPS systems and would like to know what is needed and/or who is needed to contact in order to updated the listing of compatible Tripp Lite UPS systems in your HCL list?Hi Eric,>From end users of NUT, we usually request the information mentioned under "Report new devices, omissions or errors" at http://www.networkupstools.org/stable-hcl.html#footnotesHowever, I don't want to be pedantic about getting the exact output of 'upsc' from the entire Tripp Lite product line - especially if several models share the same USB controller. Getting the 'upsc' output from a representative model should be sufficient. What would be helpful is to understand which models are similar, and whether there are any attributes we can use to differentiate between various generations of the hardware (for instance, at some point the SMART2200RMXL2U changed from the proprietary serial-over-HID to standard PDC HID). Also, we occasionally run across cosmetic errors in the output data: http://thread.gmane.org/gmane.comp.monitoring.nut.devel/6482 While this shouldn't affect the shutdown sequence, we do try to correct the returned measurements if we can identify a good algorithm. If all of the voltages are in microvolts (including the config voltages), we can apply a multiplier across the board. But if only some of the exponents are wrong, it is harder to write a general rule that won't break when the HID descriptor in the firmware is fixed. If there is a firmware revision that we can compare against, that can help isolate the bug fixes. The last piece (not visible on the HCL, but included in the data files for hotplug/udev) is the list of USB vendor/product IDs. If a new Tripp Lite product ID were to be encountered by NUT, the driver would not automatically attach to it unless the "productid" option is specified. It is a simple way to tell users that we did not know whether that device would work when that version of NUT was released, but that they can give it a shot (potentially getting incorrectly scaled voltages). We are open to suggestions on how to improve that heuristic, especially if Tripp Lite has allocated separate ranges of product IDs for UPS and non-UPS hardware. Here's the code in question: https://github.com/networkupstools/nut/blob/master/drivers/tripplite-hid.c#L57 In that file, the product IDs are matched individually, and there is a tripplite_claim() function at the bottom of the file which tries to offer advice for other IDs.

I think we have some additional homework to figure out a better way to represent all of this information on the NUT website, but for now, we can point users to the documents you provided if they need details beyond the basic model/driver information that would be added to the HCL. A couple of questions: * For the HID units, is the four-digit "Protocol" always equal to the USB Product ID? (This was not the case with some of the non-HID models, so I just want to be sure. If the only non-HID USB ID is 09ae:0001, we can adjust our drivers' detection algorithms.) * Some of the voltages look out-of-range. For instance, on the SMART1500LCDT, the battery voltage is listed as 0.0 (using NUT 2.6.3). This looks similar to the case I mentioned earlier[1], and in order to try and fix that, it would be good to know if this is limited to a specific protocol number, or if protocol 3016 might be patched in the future. [1] http://thread.gmane.org/gmane.comp.monitoring.nut.devel/6482 * Were the variables like ups.delay.shutdown verified to be mapped correctly in NUT? I see that they read back, but there is certainly a possibility that we are not mapping the names to the proper HID usage IDs. "Mike." asked a little about this particular variable earlier in the thread, and this seems to be one of the more important configuration knobs that people want to adjust. -- Charles Lepple clepple at gmail
