Page 54 2.8.8 I/O MODULES The I/O modules serve as an interface for input and output signals between the RFL 9780 and the line coupling equipment. There are several types of I/O modules that can be used with the RFL 9780. These are shown and described in Section 17.
Page 55: System Theory Of Operation
2.8.12 ACCESSORY EQUIPMENT Other circuit card modules and assemblies are available to enhance the operation of the RFL 9780 terminal, or to adapt it to special applications. If any accessory equipment was furnished with your system, an Instruction Data Sheet for each item will appear in Section 21 of this manual.
Page 56 This may be required if more than 10 watts of output power is needed. In this case, the Power Amplifier Module is omitted from the chassis. Additionally, there would be no need for the 9780 Output Filter or Hybrid, as these would be required after the external power amplifier.
Page 57 The signal is then sent into the IF/BF Module. This module shifts the received carrier from the customer specified center frequency down to the 9780’s baseband frequency of 4 KHz. There are three mixers on this module. There is a very sharp cutoff crystal bandpass filter located between the first and second mixer.
Page 58 There are two RS-232 connectors on the 9780 to access the SOE Module, one on the rear and one on the front of the unit. The rear connector is intended for permanent connection to monitoring equipment (if available) while the front connector is intended for short-term connection to a PC or terminal for system interrogation.
Page 59: Section 3. Installation
3.2.2 INTERCONNECTED CHASSIS RFL 9780 terminals ordered as part of a larger system may be interconnected with other chassis and mounted in a relay rack or cabinet, or on shipping rails for installation into a rack or cabinet at the customer's site.
Page 60: Mounting
RFL 9780 terminals housed in individual chassis have two mounting ears (one on each side). Hole sizes and spacings conform to EIA standards, so the RFL 9780 can be mounted in any standard 19-inch rack or cabinet. Complete chassis dimensions are shown in Figure 3-1.
Page 61: Ventilation
Operation at higher temperatures may affect system reliability and performance. Systems installed in enclosed cabinets should be ventilated to keep the temperature inside the cabinet within limits. To insure adequate ventilation, leave several inches of space above and below each RFL 9780 chassis when mounted in a rack or cabinet.
Page 62: Connections
Electrical connections are made to each RFL 9780 chassis through the terminal blocks and connectors on the chassis rear panel. A rear panel view of a typical RFL 9780 Tx/Rx terminal is shown in Figure 3- 2. Refer to this figure when making connections. Paragraphs 3.5.1 through 3.5.9 provide basic descriptions of all the connections that must be made.

Page 74: Power Supply Considerations
4.5 INPUT AND OUTPUT VOLTAGES The inputs and outputs of the 9780 (other than the carrier signals) are typically either 48, 125, or 250 Vdc nominal. As with the power supply, both the 48 and 125 Vdc systems utilize the same modules, while the 250 Vdc I/Os require that a different I/O Module be installed in the chassis.
Page 75: Transmit Functions
6.3.12 for more information. Note that for systems with external power amplifiers, these settings will be scaled by the external amplifier. For example with a 50 W external amplifier, a 9780 configured for 10W/10W would be a 50W/50W system, a 1W/10W 9780 would provide a 5W/50W system.
Page 76 4.7.1 LINE TERMINATION The 9780 receiver section can be configured to terminate the incoming line or not. Note that the input of the RF Interface Module is a high impedance input. The termination and protection circuits are located in the Line I/O assembly in the rear of the unit. To change the termination setting, the Line I/O Module must be removed from the chassis and the jumper selected for “50Ω”...
Page 77 4.7.3 EXTERNAL METER TYPE Two types of external carrier level meters are supported by the 9780. The nominal ±10 dB range can be mapped to either a 0 to 100 µA range, or to ±1.0 Vdc. The desired meter type is selected using jumper J1 on the CLI Module, see Paragraph 13.4.1 for more information.
Page 78 4.7.11 CARRIER ENVELOPE NOISE DETECTOR DISABLE The carrier-envelope noise detector can be disabled by setting switch SW8-1 on the logic module to the OFF position. See Paragraph 6.3.16 for more information. RFL 9780 RFL Electronics Inc. April 8, 2003 4-11...
Page 79: Initial Startup Procedure
4.8.2.1 Output Power The 9780 transmitter is specified to provide 10 W into a 50 ohm load. Adjustments to the output power are made with a 50 ohm dummy load connected. Any additional devices in the transmit path, such as hybrids, will reduce the effective output power.
Page 80 4.8.2.2 Output Impedance Once the 9780 has been connected to the line the output impedance should be adjusted to match that of the actual line. Impedance mismatches can cause signal reflections and other undesirable effects. The 9780 Power Amplifier provides an output impedance adjustment to accommodate small variations in actual line conditions.
Page 81: Table 4-3 Input Attenuator Settings, Rfl Interface Module
4.8.3 RECEIVER After the transmitters at each end of the line have been setup, the receive portions of the 9780 must be adjusted for the actual receive signal level. There is a coarse (attenuator) and fine (level) adjustment for the receive level.

The Logic Module design can be broken down into two sections: Receiver Logic and Transmitter Logic. The block diagrams shown in Figures 6-3, 6-5 and 6-6, and the 9780 Logic Module schematic diagram shown in Figure 6-8 should be referenced to follow the circuit flow throughout the discussion.
Page 104 This is done to reduce the possibility of false trips. Guard commands from the receiving section of the RFL 9780 appear as a logic-high guard input at edge connector pin C13 (GUARD_INPUT) and can be monitored at TP4. When the guard input goes high and remains high for a preset time interval, the output of the pre-guard timer will be high.
Page 105 TRIP indicator DS2 will illuminate to show that a valid trip input has been received and a trip output has been generated. If desired, the 9780 Logic Module can be configured to latch the TRIP indicator (DS2). The TRIP RESET button (SW11) located at the front of the board (protruding through the 9780 chassis) is used to reset the indicators.
Page 106 Bipolar noise is defined as a noise that causes a bipolar system to change from present state to the alternate state and then back to its original state. In the 9780, this would be a change from guard to trip to guard, or from trip to guard to trip.
Page 107 35%, CE_LOW will go low indicating low-level carrier envelope noise may be present. CE_HIGH and CE_LOW signals are applied to the blocking logic circuit within the Actel FPGA for further digital processing. RFL 9780 RFL Electronics Inc. April 8, 2003...
Page 108 6.5.1.13 ALARM TIMER The alarm timer is triggered by any abnormal condition detected by the receiver logic of the 9780 Logic Module. The logic-high NOISE_STRETCH signal applied to the input signal of the alarm timer indicates this condition.
Page 109 The alarm output circuit will produce a LOGIC_ALM output at edge connector pin A20 whenever the 9780 Logic Module is not in an alarm state. This output is used to energize the alarm relay in the (normal) no-alarm condition. If an alarm condition occurs, the transistor associated with the alarm output circuit is turned off causing the alarm relay to dropout.
Page 110 The trip-input circuits accept trip inputs from solid-state input relays at the rear of the 9780 chassis and passes them to the logic circuits. In order for the 9780 to produce a valid trip command, a zero-volt signal must appear at one or both trip inputs (edge connector pins B21 and C22) depending upon the configuration.
Page 111: Table 6-19. Valid States Of 2F And 3F Signals
The relay can be de-energized with the TRIP RESET button on the front of the module. Optionally, the 9780 Logic Module can be configured to latch the DS6 and/or DS7 indicators for a trip condition depending upon the system. The LEDS are reset with the TRIP RESET button on the front of the module.
Page 112 The outputs produced by the trip-input circuits are fed to the transmitter power level logic circuit. The configuration of the 9780 Logic Module determines how the logic circuit will react to the inputs. The transmitter power logic circuit generates the A SWITCH and B SWITCH outputs which are located at edge connector pins A14 and B14 respectively.

Page 189: Section 12. If/Bf Module
Figure 12-1. RFL 9780 IF/BF Module 12.1 DESCRIPTION The RFL 9780 IF/BF Module (Figure 12-1) accepts incoming rf signals which are shifted down to 4kHz (the baseband frequency, or bf). Its channel filter is 3700 Hz wide, which will pass FSK signals or voice sidebands of the carrier, if present.
Page 190: Specifications
Output Signal: 4-kHz baseband. 12.3 THEORY OF OPERATION The main function of the RFL 9780 IF/BF Module is to convert the incoming rf signals to a 4-kHz bf. Basically, the RFL 9780 IF/BF performs the frequency conversion by first up-converting the signal to 5.12 mHz, by using a programmable synthesized local oscillator.
Page 191 -15V * WHEN PRESENT Figure 12-2. Block diagram, RFL 9780 IF/BF Module a. Crystal Oscillator . Transistor Q1, crystal Y1, varactor CR2, and their associated components form a crystal oscillator. This oscillator serves as the beat frequency oscillator (BFO) for the product detector, as well as the frequency reference for the frequency synthesizer.
Page 192 Onboard Regulators. Linear voltage regulators U10, U11 and U13 serve as onboard voltage regulators. U13 converts the incoming +15-volt supply voltage to a regulated +8 volts, U11 converts it to a regulated +5 volts, and U10 converts it to a regulated +10 volts. RFL 9780 RFL Electronics Inc.

There is an X-Hybrid Module, a Skewed Hybrid Module and a Dual Hybrid Module available for the RFL 9780. Each of these modules uses the same basic printed circuit board as shown in Figure 18-1. See paragraph 18.2 for more information on the X-Hybrid Module.
Page 367: Hybrid Module
18.2 X HYBRID MODULE The RFL 9780 X-Hybrid Module is a transformer-type hybrid typically used to combine the outputs of two transmitters. The X-Hybrid provides the required impedance matching and signal separation, and prevents mutual loading of the two transmitters. The impedance characteristics of the two types of X-Hybrid modules is shown in the table below.
Page 368 The X hybrid can also be used to connect two transmitters to the same line tuning unit, resulting in dual- channel transmission capabilities. In this application, one transmitter is connected across the primary of L1 , and the other transmitter is connected across the primary of L2. RFL 9780 RFL Electronics Inc. September 8, 2001...

18.4 DUAL HYBRID MODULE The RFL 9780 Dual Hybrid Module uses four hybrid transformers to connect a transmitter and receiver to a single line tuning port. The Dual Hybrid provides a high degree of signal separation by isolating the local transmitter signal from the local received signal and preventing the input impedance of the receiver from loading the transmitter.
Page 383 For this discussion, refer to the schematic diagram in Figure 18-10. The RFL 9780 Dual Hybrid Module uses four hybrid transformers to couple signals between a transmitter, a receiver, and a line tuning unit.
