One thing that is confusing me Matt, you have a 4.7k ohm resistor as what to use
between Bus-On and Gnd, where as Mike Woo quoted it as being a 10k ohm resistor.
Maybe I'm reading something wrong, but which am I supposed to use, the 4.7k
resistor or 10k, or is the difference between the two too insignificant to
matter?

Okay, here's some help on this cable issue. Below are two links to some
information on how the Phatbox-Sony cables are wired. Note that you *will need*
the 4.7k ohm resistor between ground and the blue wire. Note the color coding
and what not might be different depending on the version of cable you have. The
links are for reference only and you might find you need to interpolate a little
with respect to colors and pin numbers and what not:
What Matt Found on his cable:

What Phatbox Said:
http://www.m
atronics.com/xdp4000x/SonyCable5.pdf
Depending on what version of cable you have, things might be a little different.
Use the drawing that matches best your installation.
Are you using version 7.0 Sony firmware on your Phatbox? If you are using
anything else, you are going to have operational issues with the xdp-4000x.
Make sure you're using 7.0 Sony firmware (upgradeable through PhatManager).

For reference, here is a message from Mike Woo at Phatnoise way back when:
"We changed cable manufacturers since Matt purchased his system. The
connections are the same but the colors are different. You want to connect a
10k resistor between the blue (bus master) and orange (ground) wires. I have
attached a PDF with a detailed description of the connections (SonyCable5.pdf).
The numbers can not be seen on
the Sony connector. They can be seen on the
PhatBox connector.
An unmodified cable should work when directly connected to a head unit.
Firmware 5.00 and an unmodified cable works with simple multi-device
configurations. I'm not sure if firmware 6.00 and an unmodified cable will work
with any multi-device configurations.
The problem is with the bus master signal. It is an input. It is used for
arbitration during device initialization. Without the pull-down the signal
stays high (+5V) at all times. Thus the PhatBox has trouble knowing when is the
right time to initialize itself.
After the PhatBox is connected, it will boot and then shutdown. The PhatBox
should then force a reset after a few seconds. However, you should listen to
Matt regarding pushing reset. He would know best about using the C90.
Regards,
Mike"
