Note: Do not use the smaller J2 jumpers on
J6, as the jumper contact holes will be
distorted and will not stay on J2 if
subsequently used there.
Shipped with cover installed.
Do not install jumpers; retain cover
unless 20 pin plug is installed.
Optional connections to switching circuits
in host equipment to establish drive ID.
Pins 2, 4, 6 and 8 are driven low for
