Make Noise Brains - Manual (Page 4)

Single Pressure Points with no BRAINS attached: Note all the "Close 4 Master" locations are closed, as well
as the Expand headers.
Jumper and Cable Connections:
(Power connections for each module not shown for clarity.)
Two Pressure Points, chained: Note that the "Close 4 Master" headers are closed on the first unit (will be on
the right when installed in the case). For three or four Pressure Points, use 4-header CHAIN cable and leave
"Close 4 Master" headers open on all units but the master (rightmost when installed/leftmost from behind).
Also, note the jumpers on the EXPAND headers.
