xilinx impact 6.1 does not see the cable3,xp

[blisca]

Even though i built the cable3 following xilinx drawings,i have 5 volts on
cable3 supply,and the lpt1 works with other applications,i still have the
message :"Communications with the cable could not be established.Check cable
connections and cable power source"
Can someone help me?
Thanks

Xilinx has some kind of proprietary marker in their JTAG programming
heads that Impact recognizes. I have found no way around it. For v6.1
you will have to buy a DLC5 or higher (Parallel IV) cable, or one of
the newer USB cables. Sometimes you can find them on E-Bay for about
1/3 the cost of a new one.

Good Luck,
Tom

Thank you Tom,I was so naive ,that i thought that this schematic was all i
need
http://www.xilinx.com/support/programr/jtag_cable.pdf
it should be the so-called cable III,that is included in the impact
programming options
anyway,i connected a logic analyzer to the parallel port and i didnt noticed
any signal variation when impact checks the cable,
this makes me think about drivers problems too,but maybe i just tested the
port in the wrong way
Thank you again,
Diego.

Hey, that's what my homebrew parallel cable is based on! It works fine with
IMPACT, no "magic marker" or secret handshake necessary...

Thank you Philip,i just would like to know:
wich kind of OS you use on that
wich kind of parallel port bios configuration,ecp,epp etc
thanks
