There are two common types of S/PDIF digital connectors: 
  - Co-axial (RCA) 
  - Optical (TOSLink) 


CO-AXIAL:
---------
Use a co-ax cable (RG-59U with RCA plugs, 75 ohm resistance) for digital 
transfers from a DAT machine to a co-axial S/PDIF I/O and vice versa.

- A pair of shielded video interconnect cables with RCA plugs should 
  work fine.  

- Standard audio interconnect cables are not designed to transfer 
  high frequency digital signals and may cause data errors if used 
  for S/PDIF audio data transfers. 


OPTICAL:
--------
Use a TOSLink optical cable for digital transfers between a DAT machine, 
MiniDisc, CD player or CD recorder that is equipped with optical S/PDIF
connectors.

- These are the same cables as used by Alesis for their ADAT 
  series of multitrack digital recorders.  

- Most portable MiniDisc recorders only have an optical Digital In (no digital
  output). This Digital In is usually a 1/8" phone jack that does double duty
  as an analog Line In. This requires a special optical cable with a TOSLink 
  optical connector at one end and a 1/8" optical connector at the other. 
  Connect the TOSLink optical connector to the S/PDIF Optical Output on the 
  Montego II Digital I/O bracket and connect the 1/8" optical connector to the
  MiniDisc recorder's Digital In.
