| |When mounting the 4th MUX board ("N"), screws can be placed |
| |on the nylon spacers to fix the boards together. Note that |
| |the other spacers could be used for this purpose. |
| |Connect ribbon cables (16 wires) from board 3 to board 4 as |
| |previously described. Connect the red wire (12V) of MUX |
| |board "M" to the 12V terminal of the right screw terminal |
| |of MUX Board "N". Connect the black wire (GND) of MUX board |
| |“M” to the GND screw terminal on MUX board “N”. |
