Setting up the Transmitter Setting up the Transmitter 1. Place the 7226HT in the 7180M Chassis. 2. Apply AC power to the chassis. The Power Supply and Laser LEDs should be lit. 3. Using an optical power meter, measure the optical power. Insert the meter’s cable into the Transmitter’s optical connector.
1. Line Up the Polarity Key. 2. Insert the connector 3. Tighten the connector Do not apply any glue, silicon adhesive, or any other Caution material to the fiber optic connector! 7226H Interfacility Link Installation and User’s Guide page 9 Foxcom proprietary information...
Setting Up the Receiver Setting Up the Receiver 1. Place the 7226HR Receiver in any of the 7180M Chassis, unless a 2040 RF Switch is installed. (See Figure 8 7180M Chassis Rear View page 12.). If a 2040 RF Switch(s) is being installed, then slots 2 and/or 5 of Note the 7180M are reserved for the switch(es).
(excluding LNB Drive option). • Receiver power requirement: 14 or 18 VDC @ 360mA. • The Standalone Transmitter/Receiver is powered by a Foxcom supplied external DC power supply. • The Rackmount Transmitters/Receivers are plugged into the rackmount chassis. The chassis can accept and power up to eight units.
The power supply provides: • 15 or 18 VDC stable • AC input; 100 - 240 VAC • Units can be plugged in “hot standby” Figure 7 7180M Chassis Rear View 7226H Interfacility Link Installation and User’s Guide page 12 Foxcom proprietary information...
3. If the 2040 Switch is installed in Slot 2, place the JP1 and JP2 jumpers on the higher two pins and the JP3 and JP4 jumpers on the lower two pins. Figure 9 Jumper Installation: 2040 Switch in slot 2 7226H Interfacility Link Installation and User’s Guide page 13 Foxcom proprietary information...
5. If the 2040 Switch is installed in Slots 2 and 5, place the JP1, JP2, JP3, and JP4 jumpers on the higher two pins. Figure 11 Jumper Installation: 2040 Switch in slots 2 and 5 7226H Interfacility Link Installation and User’s Guide page 14 Foxcom proprietary information...
6. Adjust the Receiver Gain Control for unity gain. Figure 12 Fiber Optic Alignment Setup If you are unable to perform this procedure see Chapter 4: Gain Control on page 27. 7226H Interfacility Link Installation and User’s Guide page 15 Foxcom proprietary information...
Monitoring the Input/Output Signal Monitoring the Input/Output Signal On the front panel of the 7226HT transmitter and the 7226HR Receiver is a F-Connector. This connector, which is labeled RF Test, is used to monitor the Input RF signal transmitted to the Transmitter and the RF output signal transmitted from the Receiver.
This specification is true when: IMD = -40 dBc, Pout = -5 dBm Full gain range is obtainable when in the input/output signal power is within the speci- fied range @ maximum input With no damage 7226H Interfacility Link Installation and User’s Guide page 17 Foxcom proprietary information...
