I am trying to enable DV-IN on a Sony DCR-TRV 125se camcorder, using
the schematichs from http://www.sps.volyne.cz/set1394/anin/adapter.html
(left one)
However, when I connect it to the LPT port, it does not work The cable used to work with another computer (back in '98 ), but it does not work with a laptop now.
What can cause it?
Difference in voltage between camcorder's LANC port and LPT port?
Check in your BIOS ( when you restart the computer, need to press DEL on the keybaord ) and check that your setting to the LPT port are set as EPP or ECP as said in the link.
Also, go back to the main page and read everything. I saw some coments there that look very importnat! http://www.sps.volyne.cz/set1394/
Good luck.
