The CM4 Common Module has three sets of jumpers that must be set for proper system operation.
These are J8, J3 and J4. Refer to Table 4-1 for information on how to set these jumpers.
NOTE
External timing of the CM4 in an IMUX 2000 M-DACS is not required. External timing is
done through the DASC module via the communications I/O (MA-235).
