I am rather disappointed in that but there is not much we can do about it. I looked around the site for firmware upgrades and found none. There are also no instructions in the manual on accomplishing a firmware upgrade. Just for grins I looked for firmware upgrades for a couple of other models in a different series of UPS units and found no firmware upgrades for any of those as well. It would appear that they either do not believe in firmware upgrades or I am looking in the wrong spot. I suspect the former as there is nothing in the sales literature as well and normally when it is possible for a piece of equipment to accept firmware upgrades, the manufacturer lists it as a feature. As an aside, is it possible that using the RS-232 port would produce different results? I would think both drivers would expect the data to be in the same format so the results would be the same as well but thought I would ask to be sure.

The "powerpanel" driver is marked as experimental, but it doesn't bear any relationship to the HID PDC code. Worth a try. Note that some UPSes don't like switching between USB and serial without power-cycling. If you don't get any results from the serial driver, you may need to completely power down the UPS, and pull it from the wall long enough to let some of the power supply capacitors drain. -- Charles Lepple clepple at gmail

After looking at what they sent me it was obvious that the serial port despite what you might expect is not really meant for communication at all. All it does set a few pins high or low to signal low battery and power out. Pins 2 and 3 are not even used. A complete waste of time. At this point I don't think I would recommend CyberPower units for any server application Their serial communication is serial with no communication and the provided USB software does not have a web interface for remote monitoring. They say the CP1500 is for low mid to size server use but it really isn't. It is just for the home market where it sits next to a Windows PC in the same location as the user. Unless someone has another suggestion, my only hope is that sometime NUT's usbhid-ups gets updated to work with it. I am certainly willing to do any beta testing.
