Hi there is the link on your account so we are going for a call from your client tomorrow at the latest and I’ll let you know if I have to wait till

If you intend to use the PLIP protocol between two machines then this cable will work for you irrespective of what sort of parallel ports you have installed.

· Do not connect the pins marked with an asterisk `*'.

· Extra grounds are 18,19,20,21,22,23 and 24.

· If the cable you are using has a metallic shield, it should be

  connected to the metallic DB-25 shell at one end only.
  Warning: A miswired PLIP cable can destroy your controller card. Be
  very careful and double check every connection to ensure you don't
  cause yourself any unnecessary work or heartache.

While you may be able to run PLIP cables for long distances, you should avoid it if you can. The specifications for the cable allow for a cable length of about 1 metre or so. Please be very careful when running long plip cables as sources of strong electromagnetic fields such as lightning, power lines and radio transmitters can interfere with and sometimes even damage your controller. If you really want to connect two of your computers over a large distance you really should be looking at obtaining a pair of thin-net ethernet cards and running some coaxial cable.
