5.2is3 iMPACT- Using IBM Thinkpad, Cable autodetection (connection) fails for Digilent's Digilab XC2 (CoolRunner-II) demo board

Description

General Description: 

When using IBM ThinkPad (Laptops), 5.2i and 6.1i iMPACT are unable to find the parallel cable provided with the Xilinx Digilab CoolRunner-II demo board.

Solution

This problem is caused by the resistor between pin 8 and 11 of the DB25 connector and ThinkPad's parallel port driving strength.  

 

To work around this issue, simply turn the board around and short pin 8 and 11 or pin 8 and 12 of the DB25 connector (parallel port).  

 

A detailed drawing can be found on the Digilab's user manual.
