Assemble the zBus chassis with Optibit interface.
The RZ or zBus chassis (racks) connect to the PO5/PO5e/LO5 through the
Optibit interface to form a communication loop between the PC and the TDT
hardware. With the RZ, access to the Optibit interface is found on the back
panel. In a zBus chassis, the Optibit interface is an FO5 module mounted in a
rear bay. Use the provided fiber optic cables to make the connections
described in the step-by-step instructions below.
Be sure to remove the clear plastic protective plugs from the ends of the cables
first. The fiber-optic cables have raised keys on one side of the connector.
There are also keyway notches on the inside of the connectors on the RZ or
FO5 module and the PO5/PO5e/LO5 interface. The fiber-optic cable should be
oriented so that the keys on the cable connectors line up with the keyway
notches on the modules.
When connecting the fiber optic cable,
grasp the cable by the cap and push
firmly. You will hear a click when the
cable is connected securely. When
disconnecting, grasp the cap and pull
straight out. You will first notice the
cap sliding backward slightly. This
unlocks the cable and allows it to be
removed. This locking connection
prevents accidental disconnects.
