Hi, I've got a apc Smart-UPS DP 8000 XL and a 940-0024c cable., and when I launch upsdrvctl, I've got the following message : Network UPS Tools - UPS driver controller 2.0.2 Network UPS Tools (version 2.0.2) - APC Smart protocol driver Driver version 1.99.7, command table version 2.0 dstate_setflags: base variable (input.transfer.high) does not exist dstate_addenum: base variable (input.transfer.high) does not exist dstate_setflags: base variable (input.transfer.low) does not exist dstate_addenum: base variable (input.transfer.low) does not exist dstate_setflags: base variable (input.sensitivity) does not exist dstate_addenum: base variable (input.sensitivity) does not exist dstate_setflags: base variable (battery.charge.restart) does not exist dstate_addenum: base variable (battery.charge.restart) does not exist Detected Smart-UPS DP 8000 XL [gs9941001285 ] on /dev/ttyS0 after that I can use uspc to get some information, I wonder if the Smart-UPS DP is not working like a standard apc smart-ups. or the driver have to be updated? thanks Shah Mohsin WAHED
