6 - FOR DBK33 USERS ONLY! Configure the P1 interconnect board for power source.
This step only applies when a DBK33 is being used with the system.
If you are not using a DBK33 skip to step 7.
The schematic to the right shows the LogBook/360 jumpers, JP1 and
JP2, which are used to distribute the LogBook’s +5V power supply.
DBK cards that attach to the LogBook’s P1 bus need +5V, +15V, and
-15V power sources to operate. Typically, the LogBook’s power supply
meets this requirement, but if additional power is needed, a DBK32A or
DBK33 must be added.
The LogBook’s power supply employs diode protection on its +/-15V
supplies so that no conflict will take place when a DBK32A or DBK33 is
added to the P1 bus. However, adding a DBK33, with its +5V source,
necessitates the proper positioning of the JP1 and JP2 jumpers.
Adding a DBK33 to your system with the jumpers set incorrectly can
damage your LogBook, DBK33, and other system components. Refer to
the following table for important information regarding configuration.
CAUTION
Adding a DBK33, with its +5V source, necessitates the proper positioning of the JP1 and JP2
jumpers on the LogBook/360 P1 interconnect board. Adding a DBK33 to your system with the
jumpers set incorrectly can damage the LogBook, DBK33, and other system components.
WHEN JP1 AND JP2 JUMPERS ARE IN PLACE A DBK33 CANNOT BE USED IN THE
SYSTEM!

In Out Yes No When the JP1 jumper is in place and the JP2
jumper is out, if the system is using external
DBKs the DBK33 will need to be external.
Internal DBKs will be powered from
LogBook’s internal P1 bus.
Out In No No When the JP1 jumper is out and the JP2
jumper is in place, if DBKs are used
internally or externally, the DBK33 can be
internal or external and will power both
internal and external DBK cards.
Out Out No No When the JP1 and JP2 jumpers are both out,
the following apply:
o If using internal DBKs, you will need to
use an internal DBK33.
o If using external DBKs, you will need to
use an external DBK33.
* Refer to the LogBook/360 Hardware Setup figure on page QS360 -3 for the P1 interconnect board’s location.
Leave jumpers JP1 and JP2 in place, unless a DBK33 is being used. If a DBK33 is being
used configure the P1 interconnect board according to the above table.
