I have a question about real-world cable lengths in use in Ultra 320
environments.  SPI-5 lists the cable lengths at 25 m for point-to-point
and 12,5 m for multi-drop.   
Is there anybody out there who is actually using 25 m cables in point to
point without any issues? 
Is there anybody out there using 12,5 m cables with mulitple devices
attached without any issues? 
How many devices have successfully been used on one cable? 

Thanks,
