Pay attention to the resistor pack orientation:
They are marked with a dot at pin 1, all 8 packs must be installed with pin 1 towards the J1 end of the PCB.

# Location Detail Description                              
J1 Interface to CORE:J9 (if buttons are used) and CORE:J6 (if encoders are used, MIDIbox16E only). DINX4:J1 provides two power pins for 5V/0V, the serial clock, the latch enable and the serial output of the register chain. This port can also be connected with J2 of another DINX module.
J2 Interface to another DINX4 module. DINX4:J2 provides nearly the same pins like J1, just only the serial output of the first IC is replaced by the serial input of the last IC. This port can be connected with J1 of another DINX module.
J3 Digital input lines
J4 Digital input lines
J5 Digital input lines
J6 Digital input lines


Size: 100mm x 45mm
Double sided PCB design.
Plated through holes.
Green LPI solder mask both sides.
Electroless nickle/immersion gold pad plating. (RoHS compliant)
White topside legend silkscreen.
No jumpers.
Electrically tested.
FR4 laminate.


Changes from R3 PCB:
Changed/corrected J3, J4, and J5 connections to match legend.
