My apologies for posting this without summarizing the original article.
However, as it refers to a safety issue, I feel the completeness is
appropriate.  In the attached article, Farrell Woods points out that the
(Dec) LK201 keyboard warns the user against using an unapproved cable.
Because he refers to "really cheap cables", the reader may incorrectly
decide that expensive cables would work.  While the LK201 cable looks
like a standard modular phone cable, it is build using significantly
heavier gauge wire -- as it carries the power needed by the keyboard.
Ordinary LK201 usage exceeds the rated capacity of standard modular phone
cables.  You can order replacement cables from Dec Direct.
