MACRO CPU Board
3U MACRO CPU Board Hardware Setup 9
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.
