Getting to Know Your ABP-2000
©Vecow ABP-2000 Series Advanced Box PC User Manual
It is for connecting an eSATA storage device. There
was no clear mechanism to distinguish if a mSATA drive
or a Mini PCI-E device is plugged into the socket until
recently that SATA-IO issued an ECN change (ECN
#045) to re-define pin 43 on mSATA connector as “no
connect” instead of “return current path” ( or GND).
When an mSATA drive is inserted, its pin 43 is “no
connect”, and the respective pin on the socket is
being pulled-up to logic 1. When a Mini PCI-E device
is inserted, its pin 43 forces the respective pin on the
socket to ground, or logic 0.
