The D20E modules have two DIP switches on the internal Logic board assembly:
•
CFG RESET and
•
WDI.
These DIP switches are factory set and must not be changed.
Table 39 specifies the DIP switch settings which must be in place in order for the D20E
module to operate correctly.

CFG RESET
WDI
Do not press the CPU RST or the K10 Reset push-button switches. Pressing either of these
switches causes the D20E module to reset or restart.
