Front Panel - P4P800 Deluxe

[William J. Burlingame]

The connectors from the front panel audio are labeled:

MIC-IN
MIC-PWR
R-OUT
L-OUT
RET-L
RET-R
GROUND


Those on the board are labeled:

MIC2
AGND
MICPWR
+5VA
LINE_OUT_R
NLINE_OUT_R
NC
LINE_OUT_L
BLINE_OUT_L


What connects to what? I've connected the USB's and tested them. The
USB cable had all the lines as a single connector.

I haven't done the 1394 yet, I don't have a unit to test the
connector.

The 1394 lines from the case are:

TPA-

VCC

Those on the board are labeled:

Since the wire names remind me of the Antec Sonata, here is an Antec
web page:

http://www.antec-inc.com/support_roductInfo_FAQ.php?Qnumber=5&FAQno=15

Note that Antec is reversing the MIC-IN and MIC-PWR wires from the
info I've given above. This is because Antec reversed them in the cable
assembly, so they are asking users to reverse them at the motherboard.
It is "two wrongs make a right". If you find your electret microphone
doesn't work, reverse them. Same is true of a passive microphone. The
MIC-PWR signal is +5V isolated with a 1K ohm or 2K ohm resistor - the
resistor limits the current, so reversing the wiring won't hurt anything.
Just stay away from the +5VA pin on the motherboard header, as it
connects directly to +5V power, and can blow anything you connect to
it by mistake.

As for Firewire (IEEE1394), Antec cannot get those right either.
On my case, the data+ and data- signals were reversed in each pair.
Thankfully the power pins were wired correctly. So, with this Antec
mistake, no Firewire peripheral gets burned. The following
wiring assumes that Antec has fixed this. If it doesn't work, swap
TPA+ with TPA- and TPB+ with TPB-. Be very careful with the +12V
pins on the motherboard header, as connecting them to a TPA or TPB
by accident could fry the I/O on a Firewire peripheral.

TPA0+ TPA+

Another user recently posted that the Antec dual USB wiring mixes
the data signals between the two connectors. I recommend buying a
multimeter and setting it to ohms, to "buzz out" the cable assemblies
and verify they are correct.

Case manufacturers are only good at "banging on metal". They haven't
a flying ******* clue when it comes to wiring. I wonder how many
of their employees go to work in the morning with their pants on
backwards!

Thanks for the info.

I thought VCC was 5V. I'm just an old retired SW guy, so don't expect
me to know much about wiring either.

A side note - in the 70's, home computers were delivered as bags of
parts. I wired the power supply with the red and black wires
reversed. My logic was that in house wiring, black is hot. I
received some chuckles from my HW friends.

The case I'm using with this system is a PowMax.

The audio works. Thanks. I don't have any firewire devices, so it's
hard to test that connection. The solution looks valid though.
