DTL-H10000S or SCPH-10000?

[xslt2002]

Hello,
I'm currently own a PlayStation 2 Debugging Station ( DTL-H10000S NTSC J ... as stated behind the black box ) and I'm quite confuse wether it is a DTL-H10000S or SCPH-10000. It shows DTL-H10000S outside the box but when I go to the Version ( by pressing the triangle when it boot up with no AR2V2 CD ) it says the unit is SCPH-10000. Which one is mine? Is it DTL-H10000S or SCPH-10000?

And will origa modchip works well in my PS2? What version? What are the limitation, if available? I also have AR2V2 to plays PS2 backups ( CDROM ). Can I play DVD games and movies ( there are DVDROM symbol but no DVD Movie symbol on the box )?
Thanks in advance.
