3.5.8 OTHER CONNECTIONS
TB6 is an unused terminal block on the rear panel of the RFL 9785. This terminal block can be used
for making connections to any accessory equipment supplied with your RFL 9785 terminal. Refer to
the “as supplied” drawings furnished with your terminal for further information.
3.5.9 RF INPUT/OUTPUT CONNECTIONS
There are two rf connectors on the rear of the RFL 9785 chassis which are marked "TX" and "RX".
These connectors are normally connected together with an internal jumper. When external hybrids are
used, the outgoing coaxial cable is connected to the TX connector, and the incoming coaxial cable is
connected to the RX connector.
WARNING
THE RFL 9785 CHASSIS MUST BE PROPERLY GROUNDED AS DESCRIBED IN
THE FOLLOWING PARAGRAPH BEFORE ATTEMPTING TO CONNECT INPUT
POWER. IMPROPER GROUND CONNECTIONS MAY RESULT IN SYSTEM
MALFUNCTIONS, EQUIPMENT DAMAGE, OR ELECTRICAL SHOCK.
3.5.10 CHASSIS GROUND CONNECTIONS
A threaded ground stud at the rear lower right of the RFL 9785 chassis is the main ground for the RFL
9785 terminal. Grounding is accomplished by connecting a wire 6AWG or larger between the ground
stud and rack ground. The grounding wire should be kept as short and straight as possible, to keep its
resistance and inductance to a minimum.
Before attempting to make power connections, make sure the RFL 9785 terminal is equipped with a
power supply designed to operate at the available input supply voltage. This can be determined by
checking the model designator on the module handle. If an external power supply is being used, check
the markings on the external power supply. If the wrong voltage is connected to the power supply,
component damage will result.
