la manip pour debridé le PC4 (et probablement PC5) de maniere permanente marche effectivement !




These instructions apply to the Sony PC4 and PC5 and maybe
to other Sony models that use the same codes (testé avec succès sur TRV120).
However, the
hack that enables checksum changes may also work with other
2nd generation Sony camcorders. Experiment at your own risk.

Do not attempt to modify your camcorder if you don't know
exactly what you are doing - buy a commercial software or
widget instead. I only tested this once and only on one
camcorder. Please understand that there is NO guarantee
that this information will be accurate for your camcorder.

A real Sony RM-95 wired remote was used to gather and test
this information, but the various RM-95 PC emulators should
work just fine with Sony camcorders.

Please note that this is NOT an RM-95 tutorial. If you do
not know how to use an RM-95 or an emulator, or if you need
info on building a LANC cable for the PC, you can easily
find detailed instructions elsewhere on the web.

------------------------------------------------------------

Format of the instructions below:
(don't touch your camcorder yet, wait for step 1)

00:01 = go to page 00, address 01
00 -> 01 = change data from 00 to 01 using Data+ or Data-
W = write (and of course no "W" means do not write)
(W) = not sure if write is required, but I did it and
it didn't cause any problems

------------------------------------------------------------

PERMANENT DV-IN ENABLE PROCEDURE

1. Inspect old checksum value:

Write down the data values found at 02:F0 and 02:F1
(you may need them later to undo if this doesn't work)
The PC4 I tested had 02:F0=23 and 02:F1=04

2. Enable changes on page D:

00:01 00 -> 01 (W)

3. Modify data on page D:

(ici faire les modifs souhaitées en page D : DV-in, Zebra, balance des blancs
manuelle, etc...
suivant les tableaux que l'on trouve un peu partout. Pas besoin de compensation
de checksum .)

0D:14 24 -> 26 W
0D:2C 12 -> 13 W

4. Inspect new checksum value:

Take note of the new values in 02:F0 and 02:F1
(you'll need them in the steps listed below)
The PC4 I tested had 02:F0=20 and 02:F1=07

5. Enable checksum update:

00:FF 00 -> 02
00:01 01 -> 80

6. Update checksum value:

NOTE: the actual values to be used here are the ones you
noted in steps 1 and 4, I had 23 04 for the old checksum
and 20 07 for the new one.

0F:FF 23 -> 20 W
0F:FE 04 -> 07 W

7. Disable further changes:

00:FF 02 -> 00 (W)
00:01 80 -> 00 (W)
