internal fiber-optic interface,
position the adhesive square on the top of the
920i
power supply shield (see Figure 2-14 on page 14).
Press the fiber-optic interface backplate onto the
adhesive square, then install the interface board onto
the backplate.
Attach fiber-optic cables to connectors V1 (receive)
and V2 (send). Attach RS-232 communications cables
from connector J3 on the fiber-optic interface to any
available
920i
serial port. Use cable ties to secure
communications cables inside the indicator enclosure.
Power to the
920i
internal fiber-optic interface is
provided by tap and run connectors on the +6V and
GND wires between the
920i
power supply and the
indicator CPU board. Attach power supply wires to
connector J4 on the fiber-optic interface. See
Section 2.12 on page 14 for installation information.
