APU set up with Wi-Fi

I agree we are talking the same thing. :) We must be since all three of us have used a console cable and are aware of what's required.
Reading back through it I can see where the confusion started. Forbiddenlake said you need an adapter as well as a USB-Serial converter, which is true you do. You had already stated you need a console cable which is the same thing. However you then wrote 'no you don't' meaning you don't need the adapter as well as the console cable. I then misinterpreted that as you saying you don't need any sort of adapter. ::)
Anyway just to be clear you need a null-modem cable also known as a console cable (the null-modem adapter is the same thing but shorter) and, if you don't have a serial port, you need a USB-serial converter.

Agreed :D

The Serial-USB and serial female-serial female cables arrived.
Micro SD 4GB card with the pfSense-2.1.2-RELEASE-4g-amd64-nanobsd-20140410-0542.img downloaded onto it,
I bought a 12V 1.5A power supply but no power to ALU?
Specs/tutorial for building the APU say a power supply of 1 - 2 Amps should be fine.Plugged serial-USB cable into
serial female-serial-female to ALU serial male port and into
computer's USB port, but computer recognises no USB?Ok, tested power supply using a multimeter.
Red cable plugged into VOhmmA
Black cable plugged into COM.
Yellow dial turned to 750 V AC.Black cable pushed into the inside of the 2.5mm power supply connector (positive).
Red cable touching the outside of the 2.5mm power supply connector (negative).
Multimeter result: HV 026.Red cable pushed into the inside of the 2.5mm power supply connector (positive).
Black cable touching the outside of the 2.5mm power supply connector (negative).
Multimeter result: HV 000. -
Your power supply is almost certainly fine. To test the output with a multimeter you need to be on the correct range (if it's not auto-ranging). The '750V AC' setting is for measuring high voltage AC, such as the Volts at a wall socket. To measure the PSU, which is 12V DC, you need a low voltage DC setting. Typically that would be 20V DC or sometimes written 19V DC since the display can only read to 19.99V.
The output plug of the PSU is usually 'centre positive' so the red lead should go down the center of the connector.Do you have links to the actual cables you bought?
If the computer is not detecting the USB cable then it can't work. What OS is running on the terminal computer?Steve
-
Thanks for the help.
Multimeter yellow dial set to 20V.
Black cable pushed into the inside of the 2.5mm power supply connector (positive).
Red cable touching the outside of the 2.5mm power supply connector (negative).
Multimeter result: 12.1.Red cable pushed into the inside of the 2.5mm power supply connector (positive).
Black cable touching the outside of the 2.5mm power supply connector (negative).
Multimeter result: - 12.1.Serial female to female cable.
So yes, it seems the power supply is working.
No life at all on the APU?
Maybe the APU needs a trick like connecting an Ethernet cable or powering up and then putting the microSD card in the APU? -
Ok, check the leads at the multimeter end. The black lead is definitely in the COM connector and the red lead in the ' VOhmmA' connector?
Just as an aside here, I'm not sure how familiar with meters you are, do not put the red lead in the other connector, usually marked '10A', unless you know what you're doing. It's so very easy to kill powersupplies doing that! ;)
If the leads are correct then it looks like your power supply is wired 'centre negative' which is incorrect:
@http://pcengines.ch/apu1c.htm:
12V DC, about 6 to 12W depending on CPU load. Jack = 2.5 mm, center positive
Maybe you typo'd the results? Where did you source the PSU?
Steve

So
the power supply cable tip had the negative cable end with the 2.5mm metal positive.
the power supply cable tip had the positive cable end with the 2.5mm metal negative.I changed
the power supply cable tip with the negative end with the 2.5mm metal negative.
The power supply cable tip with the positive end with the 2.5mm metal positive.Black cable pushed into the inside of the 2.5mm power supply connector (positive).
Red cable touching the outside of the 2.5mm power supply connector (negative).
Multimeter result: -12.13.Red cable pushed into the inside of the 2.5mm power supply connector (positive).
Black cable touching the outside of the 2.5mm power supply connector (negative).
Multimeter result: 12.13.The ALU now shows a green LED light on the MOBO D7, D10 and D11.
The computer isn't showing any recognition of a USB connection.
My OS is Linux Mint 16 Mate 64-bit. -
You'll have to check the logs in Mint to see what it made of the cable. It could be some obscure converter chip.
Steve

Ok, not sure how to find logs on Linux Mint 16.
I went to /var/log, but nothing really re USBs?I'm wondering if the MicroSD card is causing the pfSense OS to somehow not load and 'awaken' the USB port?
The MicroSD card has pfSense-2.1.2-RELEASE-4g-amd64-nanobsd-20140410-0542.img on it.
I downloaded this file from pfSense download
> Computer Architecture: AMD64 (64-bit) > Platform: Embedded (NanoBSD) typically with CF > Console: Serial > CF card size: 4GB. -
Logs are usually in the /var/log directory
-
USB logs should be in /var/log/messages
You can run a tail -f /var/log/messages which is a live display of the log. Or use a cat or vi command to see the log
-
Thanks for the suggestions.
/var/log has no directory or file names messages?
Just these ones:
/var/log $ ls alternatives.log auth.log.4.gz dpkg.log kern.log.2.gz pm-powersave.log.3.gz teamviewer alternatives.log.1 boot.log dpkg.log.1 kern.log.3.gz pm-powersave.log.4.gz udev alternatives.log.2.gz bootstrap.log dpkg.log.2.gz kern.log.4.gz pycentral.log ufw.log alternatives.log.3.gz btmp dpkg.log.3.gz lastlog samba unattended-upgrades alternatives.log.4.gz btmp.1 dpkg.log.4.gz mail.err speech-dispatcher upstart alternatives.log.5.gz ConsoleKit dpkg.log.5.gz mail.log syslog vbox-install.log apt cups faillog mdm syslog.1 wtmp aptitude dmesg fontconfig.log mintsystem.log syslog.2.gz wtmp.1 aptitude.1.gz dmesg.0 fsck mintUpdate.history syslog.3.gz Xorg.0.log auth.log dmesg.1.gz hp news syslog.4.gz Xorg.0.log.old auth.log.1 dmesg.2.gz installer pm-powersave.log syslog.5.gz Xorg.20.log auth.log.2.gz dmesg.3.gz kern.log pm-powersave.log.1 syslog.6.gz Xorg.20.log.old auth.log.3.gz dmesg.4.gz kern.log.1 pm-powersave.log.2.gz syslog.7.gz

Maybe the memory card doesn't work?
I think the APU is supposed to have a Compact Flash 4GB card, but I have a MicroSD card 4GB? -
So, just ordered a new Serial female to female adaptor, in case the current serial female to female cable is faulty.
I also removed the APU's microSD 8GB card > placed the microSD 8GB card into the memory card reader > placed the memory card reader into the computer's USB > opened the microSD 8GB card's folder > unzipped pfSense-2.1.2-RELEASE-4g-amd64-nanobsd.img.gz > deleted pfSense-2.1.2-RELEASE-4g-amd64-nanobsd.img.gz > kept the unzipped file pfSense-2.1.2-RELEASE-4g-amd64-nanobsd-20140410-0542.img > ejected the memory card reader > removed the microSD 8GB card from the memory card reader > placed the microSD 8GB card into the APU > powered on the APU > connected the APU into my computer's USB port > the computer is still not recognising any USB from the APU (the computer recognises other USB devices ok).
I also tried the APU USB cable in another computer which recognised no USB when plugged into the 2nd computer.

Neither that adapter or the cable you linked to earlier are null-modem cables which is what you need. Something like this:
http://www.ebay.com.au/itm/1-5m-Serial-RS232-Null-Modem-Cable-Female-to-Female-DB9-FTA-DB9F-F-/161195465404?pt=AU_CablesConnectors&hash=item2587ff9abcI assume you're in Australia. :)
Try looking at the syslog in Mint:
cat /var/log/syslog|grep usb
or tail it whilst you plug in the cable:
tail -f /var/log/syslog

Thank you for the reply.
Forgive my ignorance, but what is the difference between the
null-modem cable and the
serial female to female cable I bought or the
serial female to female adaptor I bought?Not quite sure what I'm looking for with the below commands.
I have included the output if it helps check the USB with the APU cable plugged in.$ cat /var/log/syslog | grep usb May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.342528] usb 2-1.2: new full-speed USB device number 3 using ehci-pci May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.436085] usb 2-1.2: New USB device found, idVendor=1a86, idProduct=7523 May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.436090] usb 2-1.2: New USB device strings: Mfr=0, Product=2, SerialNumber=0 May 16 11:20:26 linuxmint-Z68MA-D2H-B3 kernel: [ 9232.436093] usb 2-1.2: Product: USB2.0-Ser!

A null-modem cable has the transmit and receive lines crossed such that two machines with standard serial ports can talk to one another. A standard serial cable for connecting a PC to some other serial device does not.
See:
http://en.wikipedia.org/wiki/Null_modemIt looks like your USB-serial adapter was recognised just fine:

You should be able to open ttyUSB0 in a serial terminal emulator, like putty. In Xubuntu there is an issue where the user doesn't have permissions to access the serial port and putty gives no helpful errors or log entries. Nice ::). The workaround is to add your user to the modem group. There may be a similar issues in Mint.

Oh, great to see the APU is connecting via the USB port.
So, I've tried a few ways to connect to the serial APU.
Terminal > $ cu -1 /dev/ttyUSB0 -s 19200
cu: /dev/ttyUSB0: System not found$ screen /dev/ttysUSB0 19200
[screen is terminating]
$ screen /dev/ttys0 19200
[screen is terminating]$ minicom
minicom: cannot open /dev/tty8: Permission denied$ sudo mincom

$ putty

Right so you have the permissions error.
Looks like it's the 'dialout' group you need to be added to. Try doingsudo adduser your_account_name dialout
Then logout and back in again. Try Putty again.
