# Location Detail Description                              
J1 Interface to CORE:J8 (if LEDs are used) and CORE:J7 (if LED-Rings are used, MIDIbox16E only). DOUTX4:J1 provides two power pins for 5V/0V, the serial clock, the latch enable and the serial input of the register chain.
This port can also be connected with J2 of another DOUTX module.
J2 Interface to another DOUTX4 module. DOUTX4:J2 provides nearly the same pins like J1, just only the serial input of the first IC is replaced by the serial output of the last IC.
This port can be connected with J1 of another DOUTX module.
J3 Digital output lines.
J4 Digital output lines.
J5 Digital output lines.
J6 Digital output lines.


Changes from R2 PCB:
Double sided PCB design.
Plated through holes.
Green LPI solder mask both sides.
HASL pad plating.
White topside legend silkscreen.
All jumpers eliminated.
2x5 DIL pinheader footprint, pads and holes added to all connections.
Bypass caps added.
Added pads for ULN2803s to allow for easy relay drive.
