4. To connect additional modules to an existing installation, first
power down the BJJ Intelligent side power pack. Move the Bus
Termination Resistor assembly from the OLD last equipped
module to the NEW last equipped module when making the final
serial bus connection to the OLD last equipped module. The
modules on the bus being modified may become inactive during
the modification. They will recover automatically when the bus
and termination resistor are restored. Restore the BJJ Intelligent
power pack to service when finished.
5. Wrap each bus wire twice through one of the supplied inductor
beads. Place the bead as close to the controller as possible.
Connect the bus wiring to the appropriate terminations on the
Remote Peripheral Monitoring interface card. Refer to Figure
3-14.
6. Refer to Section 3, Circuit Pack Addition/Removal/Replacement,
for information on adding the BJM pack into the chosen slot on
the Intelligent side of the card cage.
