(This is a resend, I exceeded list message size limit in last reply, trimmed this one) Thank you. Figuring that might be the case, I did try to access the serial port via my hacked powerchute when I was trying. I went through PowerChute’s configuration which I have to invoke with : cd /opt/APC/PowerChute ./bin/java \ --add-exports java.base/com.sun.crypto.provider=ALL-UNNAMED \ -jar ./lib/pcssconfig.jar \ skip_kernel_check Pick the username/pw/cable type/port and that rewrites the binary m11.cfg file. Note that last skip kernel check argument causes “usb” to be a menu item to select on cable type and lets the took work over USB. Anway, (my) Powerchute wouldn’t talk to it over serial either. I had bought a serial card for this and it was difficult to determine if the card had any issues so I’d switched to the laptop. I’ll try 115k too, I had not tried that. There are no serial setting exposed in the config utility, I assume it is hard coded. My serial ports experience has been even if you have the rate wrong you usually get something back from a normal serial device even if just garbage. But I realize this is not a normal device. Thanks for the suggestion. The idea was that the serial port *might* expose modbus, docs seem ambiguous on whether or not this unit has modbus. For NUT, I’d pulled the source and compiled from scratch, full version, not the plugin. With AI help it appeared that I got it (the nut utilities) to talk Microlink to the UPS over USB, but it only goes far enough to see a little back and forth then it fails with: [D1:test] Failed to open device (051D/0003), skipping: Access denied (insufficient permissions) I’ll go back and try the config options you mention below. Looking back at some notes I captured, I think I had in nut configs #ups.conf: [ups] driver = usbhid-ups port = auto #Also tried ups.conf, don’t remember which one was last: MODE = standalone FYI some log snippets of me trying…. I think this was the core roadblock I couldn’t get past: root@SERVER4:/mnt/user/logs/apc-source# /usr/local/ups/bin/apcmicrolink -s test -x port=auto -D -D 0.000000 [D1] getprocname: determined process name for PID 39939: /usr/local/ups/bin/apcmicrolink Network UPS Tools 2.8.5.1051-1051+g0d949e373 (development iteration after 2.8.5) - APC Microlink protocol driver 0.02 Warning: This is an experimental driver.

finished, exiting So almost, maybe <smile> Thanks again, Scott Hi Scott, The 2400, 8 N 1 for serial is only for the older UPSLink protocol which your UPS does not support. Your serial port almost certainly does work. For Microlink devices the serial port is NOT usable from a terminal program. I believe APS runs the serial port on Microlink UPSes at 115200. If you really want to test out the serial port on a SMX or SMC or other Microlink-only port then run Powerchute and select serial, or run the APC UPS firmware upgrade utility (from Windows) and see if it sees the serial port. But, I would NOT do a firmware update to your UPS if the update utility does see it because the current firmware update utility from APC will brick older Microlink UPSes. It's really only safe to run on a UPS that has the green SmartConnect port. If you can find a much older version of the firmware update utility that would be safe to run. I do not know if the Unraid app store has a new enough version of NUT that includes the Microlink driver you might have to compile it. Otherwise NUT will use USB-HID and that is likely what it is using to talk to your UPS. If you do have a new enough NUT that includes Microlink support then Microlink protocol works over either the serial port or the USB port. You would define it in /etc/nut/ups.conf: [apc-microlink] driver = apcmicrolink port = /dev/ttyUSB0 # Or use port = auto for USB HID tunnels The statement above would be correct for if you had a USB-to-serial port dongle. It would be /dev/ttySomethingElse if you had a real serial port, and port = auto for the USB You probably are doing something like: [myups] driver = usbhid-ups port = auto vendorid = 0764 # Replace with your vendor ID from lsusb productid = 0501 # Replace with your product ID from lsusb desc = "My USB HID UPS" in your NUT config file which runs the same protocol that apcupsd does, which is why the shutdown is similar. There are slight differences between the USB-HID procotol in apcupsd and NUT |
