5. Re-install the modified 97 DD I/O Module.
6. Connect the 64KFE modem to the RFL
9300 relay.
Plug the 64KFE, with its DB37 female
connector, into the DB-37 male connector on
the Direct Digital Interface I/O Module’s rear
panel (as shown in Figure 15-1 in your RFL
9300 system manual).
Figure 18-6 shows the pin assignments for the
64KFE’s DB37 female connector.
7. Connect the fiber optic cables to the
64KFE.
Remove the black plastic covers from the ST
type connectors at the rear of the 64KFE.
Connect one end of the fiber optic cable pair
to the 64KFE, plugging one cable into the
connector labeled “TX” and the other into the
one labeled “RX.”
8. Connect the fiber optic cables to the 64K
Module on the FOCUS chassis.
Note: If the 64K Module you are connecting
to has another interface module (i.e., 64V or
64R/G) attached, remove it before contin-
uing.
Unlock the 64K Module using the black
inject/eject lever at the front of the chassis and
carefully slide the module out until its two ST
type connectors are easily accessible. Run the
loose ends of the fiber optic cable pair through
the holes provided for the 64K Module at the
rear of the chassis. Connect these cables to the
two ST type connectors on the module. Be
sure to plug the cable from the “TX”
connector on the 64KFE into the “RX”
connector on the module; plug the cable
from the “RX” connector on the 64KFE into
the “TX” connector on the module.
When the cables are in place, carefully slide
the module all the way into the chassis until it
is well seated. Lock it into place using the
black inject/eject lever.
9. Restore power to the RFL 9300 relay.
18.6.3.2 Software Settings
The correct settings for the 64K module when
using the 64KFE fiber optic extension with the
RFL 9300 Charge Comparison Relay are as
follows:
Interface: Fiber Optic
Data Rate: 64 K
For instructions on configuring the 64K module,
please see the “Software Settings” section earlier
in this chapter.
