<P CLASS=INFO>The DOUT module comes with multiple serial registers 74HC595; every register provides 8 digital outputs, which are updated with the latch enable signal RCLK and shifted out with the clock signal SCLK. The advantage of using such shift registers is, that they can be cascaded to a long chain without the need of more than 5 cables to the core module. The DOUT board has been designed on a way which allows to cascade not only the ICs on the board, but also several DOUT modules. But note that it depends on the firmware how much outputs are processed by the core module. For instance, the MIDIbox64 allows to connect up to 64 LEDs = 8 ICs = 2 * DOUTX4, the MIDIO128 supports 128 outputs = 16 ICs = 4 DOUTX4 modules.</P>

  <P CLASS=DESC><B>Note:</B> To reduce effort only the DOUTX4 variant is available at <A HREF="http://www.mikes-elektronikseite.de/midiseite.htm" TARGET="_blank">Mikes PCB shop</A>. If you don't want to etch the modules by yourself, just use the DOUTX4 and stuff just only the ICs which are really required.</P>
