   |      Note:JP5 and JP6 select receive bus and transmit bus. |
   |      It is not known which jumper block selects which,     |
   |      although they are generally set to the same bus.      |

   |      Note:A total of 32 channel settings are available.    |
   |      The jumpers are a binary representation of the        |
   |      decimal addresses. JP1/A is the Most Significant Bit  |
   |      and jumper JP1/E is the Least Significant Bit. The    |
   |      jumpers have the following decimal values: JP1/E=1,   |
   |      JP1/D=2, JP1/C=4, JP1/B=8, JP1/A=16, . Open the       |
   |      jumpers and add the values of the jumpers that are    |
   |      open to obtain the correct channel. (Open=1,          |
   |      Closed=0)                                             |
   |                                                            |
   |      The settings for JP2 through JP4 are identical to     |
   |      those for JP1. JP1 sets the FABB channel for serial   |
   |      port 1, and JP2 through JP4 set the FABB channel for  |
   |      serial ports 2 through 4, respectively.               |
