1.  Alternate loading:
    36 discrete 10k Ohm resistors can be loaded instead of SIL 
    resistor packs, Substitute:
    | RP1-8 | 10k 6 Pin SIL resistor network     |  8  | 264-10K-RC       |
    With:
    | R1-36 | Resistor 10 kOhm                   |  36 | 291-10K          |

Alternate loading using discrete resistors:


Errata:

The input connections at J4, J5, and J6 have pins D0 and D3 transposed, and D1 and D2 are also transposed.
The connections on J3 are correct as labeled on the PCB.

The correct pinouts are:
     



Connections:


# 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 - See Errata above
J5 Digital input lines - See Errata above
J6 Digital input lines - See Errata above

Changelog: 

10.19.06:
Added Errata above to show layout error(s).

Changes from R2 PCB:
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.
All jumpers eliminated.
2x5 DIL pinheader footprint, pads and holes added to all connections.
Bypass caps added.
