MICRO LOGIC BOARD JUMPERS/SWITCHES
The Micro Logic Board can be configured for various
options (Remote/Local Control and RWT/LWT Control).
These options are available on REV. B and REV. C Mi-
cro Logic Boards.
REV. B boards actually utilize three jumpers for these
options (J8, J9, and J10). REV. C boards replace the
jumpers with a Dip Switch which has 7 miniature rocker
switches built into a single pack. 2 of the 7 switches are
active.
An explanation of the Jumpers/Switches on the Micro
Logic Board is provided on this page and page 32.
