Delta Tau MACRO CPU BOARD 4Ax-602804-xHxx - Manual (Page 13)

MACRO-CPU Hardware Reference
ACC-Ux “UBUS” backplane board. It can also be used to bring in 5V power, and optionally +/-15V power, from
a backplane or breakout board, to the entire MACRO Station.
Note
When interfacing to accessory boards across the UBUS backplane, it is strongly recommended to
use a new revision (-105 or higher) of the MACRO CPU board, and an ACC-Ux backplane board
(not an older ACC-Jx backplane board). The newer revision MACRO CPU boards have stronger
bus driver ICs, but they do not work well with the termination of the ACC-Jx backplane boards.
Power Terminal Block: The TB1 4-point terminal block can be used to bring in 5V power, and optionally
+/-15V power, to the entire MACRO Station. In a UMAC (pack) configuration, the power is more likely to be
brought in through the backplane.
