   | Note:* JMODJ is a special block placed on JMOD itself,     |
   | connecting pins 10 and 11 together diagonally. Permanent   |
   | damage to the board will occur if the JMODJ jumper is      |
   | installed improperly.                                      |

   | Pins designated should be in the closed position.          |
