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.
