Configuring apcupsd

[tonysamson]

Hi All,

I'm trying to configure my APC Back-UPS 1100 on my AC66u with Merlin firmware. I think I have installed it already and have also configured the apcupsd.conf.

I am supposed to configure the ISCONFIGURED next.

The problem is that I can't seem to find where it is. Based on my readings, it is supposed to be located in:

/etc/default/apcupsd

But it is not there.

I ran apcaccess and this is what I get:

APC : 001,018,0450

UPSNAME : ups1

Please help. Thanks.

Forget about it, just run apcupsd from /opt/etc/init.d folder.

Hi thanks for the reply.

How am I supposed to do that? Hope you can point me towards the right direction. Is there a tutorial or a guide that I can read for this one?

Thank you so much..

I tried running it from that location by typing apcupsd but nothing happened. Then I ran apctest but I still got this:

2016-02-14 11:39:11 apctest 3.14.13 (02 February 2015) unknown

If apcupsd or apctest is already running,
please stop it and run this program again.

[ryzhov_al]

Apcupsd is running. That's why apctest says some resources were locked. You may type ps to find running apcupsd in the background.
So what you want to do next with it?

 

[tonysamson]

Hi ryzhov_al,

If I run apcaccess I'm still getting this:

STATUS : COMMLOST

Does the above mean that the router is still not communicating with the UPS? Not sure if this is relevant but my UPS is APC Back-UPS 1100.

Also, when I try to access the apcupsd-cgi using my browser, nothing happens.

 

[ryzhov_al]

Does ps ax show running apcupsd?

 

[tonysamson]

Yes, I can see apcupsd running. Maybe it can't communicate with the UPS?

Here's the apcupsd.conf settings:

Type dmesg to see what the USB-to-serial driver is not loading. It would be /dev/ttyUSB0, for example.

Sorry I have to paste everything above, I really don't know what to look for on the above

 

[ASAT]

I really don't know what to look for

Which USB-to-serial chip does your RS232-to-USB cable use? Here's the choices:
PL2303
FTDI
CH340
KEYSPAN

Now you want someone to compile a USB-to-serial driver for the MIPS platform because ASUS failed to do so.

 

[tonysamson]

Well I guess this is the end of the line for me. I need to read up on this and find out what chip the Back-UPS 1100va is using.

Thanks for pointing to the right direction

 

[ASAT]

I need to read up on this and find out what chip the Back-UPS 1100va is using?

No. The chip is built into the cable. The cable also does level shifting from the UPS RS232 voltage of -12V/+12V down to the USB TTL-level voltage of 0V/+5V. You can buy these cables on eBay for $2 a piece. The cheap ones have a PL2303 chip. My UPS is not yet connected to the router, therefore I am not 100% sure.

 

[tonysamson]

Oh, I see. My UPS doesn't have this RS-232 port on it. It uses USB Type B port like the one used for printers. Could it be that the firmware doesn't have the proper driver for my UPS?

 

[ASAT]

My UPS doesn't have this RS-232 port on it. It uses USB Type B port like the one used for printers.

Do you have a modern Linux OS where you can plug it in? Then you can type dmesg to see what USB-to-serial driver it loads. I would be surprise if it requires a proprietary USB driver for the APC UPS.

Unplug the UPS' USB cable from the computer. Boot your modern Linux OS. Wait 'til it finishes booting. Plug in the UPS' USB cable to the computer. Now type dmesg to see what USB-to-serial driver got loaded.

 

[ryzhov_al]

I've found what modules was used with my APC BackUPS 650.

# cat /opt/etc/init.d/S00firmware_modules
#!/bin/sh

prefix="/opt"
PATH=${prefix}/bin:${prefix}/sbin:/sbin:/bin:/usr/sbin:/usr/bin

start() {
   insmod /opt/lib/modules/input-core.ko
   insmod /opt/lib/modules/hid.ko
   insmod /opt/lib/modules/usbhid.ko
   }

stop() {
   rmmod usbhid
   rmmod hid
   rmmod input-core
   }

status() {
   echo "nothing to do..."
   }

case "$1" in
   start)
     start
     ;;
   stop)
     stop
     ;;
   restart)
#     stop
     sleep 2
#     start
     ;;
   status) status
     ;;
   *)
     echo "Usage: $0 (start|stop|restart|status)"
     exit 1
     ;;
esac

exit 0

I hope they are still compiled with kernel, but not included into f\w image.

For Linux Mint 13, my CyberPower 1325VA shows this dmesg.

usb 2-2.2: new low-speed USB device number 5 using uhci_hcd
generic-usb 0003:0764:0501.0002: hiddev0,hidraw1: USB HID v1.10 Device [CPS  CP 1350C] on usb-0000:02:00.0-2.2/input0

For ASUS RT-AC68U router, my CyberPower 1325VA shows only this single line dmesg.

usb 2-2.4: new low speed USB device using ehci_hcd and address 16

So now I will try and see what happens when those USB_HID is complied back in. I want to see this working too.

 

[ASAT]

Thank you to ryzhov_al for the excellent patch. I got it working with the RT-AC68U router and the CyberPower 1325VA UPS.

cat /opt/var/log/apcupsd.events

2016-02-16 17:24:25 -0500  apcupsd 3.14.13 (02 February 2015) unknown startup succeeded

2016-02-16 17:25:50 -0500  Power is back. UPS running on mains.

I made this changes to the kernel config of the Asuswrt-Merlin firmware 380.57 for RT-AC68U router. Rebuilding the firmware will produce the three new kernel modules that will allow the router to communicate with the UPS's USB port.
~/asuswrt-merlin/release/src-rt-6.x.4708/linux/linux-2.6.36/config_base.6a

CONFIG_HID_SUPPORT=y
CONFIG_HID=m
CONFIG_HIDRAW=y
CONFIG_USB_HID=m
CONFIG_USB_HIDDEV=y

Copy the kernel modules (input-core.ko, hid.ko, usbhid.ko) to the router /jffs/bin and manually loaded them.

/sbin/insmod /jffs/bin/input-core.ko
/sbin/insmod /jffs/bin/hid.ko
/sbin/insmod /jffs/bin/usbhid.ko

The dmesg shows the kernel modules loaded OK.

usbcore: registered new interface driver hiddev
usbcore: registered new interface driver usbhid
usbhid: USB HID core driver

Connect the USB cable from the UPS to the router's USB 2.0 port. And dmesg shows that the router can see the UPS now.

For someone with little knowledge but is interested for things like this, I guess this is a learning challenge for me this weekend. Hoping you guys, ryzhov_al and ASAT, will be around to guide me. Thanks.
