Two 10 pin ribbon cables come from the A-154. One (A) with a 10 pin female connector (A1) at its end and another
(B) with two female connectors equipped with pin headers (B1, B2). One of the pin headers (B2) is provided with a
second "blind" female connector as short-circuit protection (in case that only one A-155 is controlled by the A-154):

(3) Connect the 10 pin female connector A1 of
cable A to the pin header ST2 of the small A-155
controller board (that has become free). Pay at-
tention to use ST2 but not ST1
! ST1 remains un-
connected ! Otherwise a short circuit is made af-
ter power on and the A-154 may be destroyed !
Pay also attention to the polarity of the ribbon
cable: the red wire
has to show to the bottom if
the A-155 module is assembled into the frame.
ST1 remains unused !
