    Switches SW1-1 through SW1-7 on the 9785 AM Logic Module allows the logic to be set according to the requirements of the specific application. The 9785 AM Logic Module also provides status information for the Sequence of Events Module.

  • Page 38: Section 8. Power Amplifier Module

    RFL 9785 Output Filter modules are used to reduce the harmonic content of the Power Amplifier’s output signal to a level that is at least 55 dB below the carrier level. In order to cover the RFL 9785's entire operating range (30kHz to 535 kHz), there are four different RFL 9785 Output Filters.
  • Page 39 2.7.8 SOE/IRIG-B MODULE AND SOE/IRIG-B I/O MODULE The IRIG-B Module is a status monitor card for the RFL 9785 which monitors input status every 1 ms. Sequence Of Events are recorded when any point changes state or if the CPU gets reset. The Sequence Of Events log is a record of the state of each point, the state of CPU reset, and the date and time the record was saved.

    4.4 POWER SUPPLY CONSIDERATIONS There are three standard station battery voltages which can be used to power the 9785 chassis: 48 Vdc, 125 Vdc, or 250 Vdc. Both the 48 V and 125 V station battery voltages require the use of a single, wide-range power supply.

  • Page 58: Transmit Functions

    4.6 TRANSMIT FUNCTIONS This section covers the configuration requirements related to the transmit functions of the 9785. The user must select the transmit frequency, the transmit power level, and how to combine the two keying input signals. 4.6.1 TRANSMIT FREQUENCIES The user must know what transmit frequency is required for the system.

  • Page 59: Receiver Functions

    9785. 4.7.1 LINE TERMINATION The 9785 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 on the Line I/O assembly at the rear of the unit.

  • Page 60: Figure 4-3. 9785 Fail Conditions

    4.7.3 EXTERNAL METER TYPE Two types of external carrier level meters are supported by the 9785. 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 J3 on the Receiver Detector module.
  • Page 61 The system can be configured for high or low voice levels using switch SW2-2 on the AM Logic module. Systems are normally configured for high voice level. See paragraph 6.3.7 for more information. RFL 9785 RFL Electronics Inc. March 24, 2008...

  • Page 62: Initial Start-Up Procedure

    This section assumes that the equipment has been installed and configured for the required application in accordance with Section 3 and paragraph 4.3. Note that the modules in the 9785 are not hot pluggable. The power to the chassis must be turned off prior to removing in or installing any modules.
  • Page 63 Disconnect the dummy load and restore the line connection. 4.8.2.2 Output Impedance Once the 9785 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.

  • Page 66: Removal And Replacement

    5.2.1 CIRCUIT BOARD MODULES All RFL 9785 front panel circuit board modules are held in place by card guides at the top and bottom of the chassis, and fit into mating connectors in the chassis motherboard. To remove any RFL 9785 front panel module, with the exception of the power supply module, proceed as follows: Lower the front cover of the RFL 9785.
  • Page 67 5.2.2 POWER SUPPLY MODULE The RFL 9785 power supply module is held in place by card guides at the top and bottom of the chassis, and fits into a mating connector in the chassis motherboard. The top guide is made of aluminum and has a locking lever to insure good heat transfer to a heat sink at the top of the chassis.
  • Page 68 5.2.3 I/O MODULES All RFL 9785 I/O modules are mounted at the rear of the chassis. Each I/O module is held in place by screws at the top and bottom of the I/O module, and fit into mating connectors in the chassis motherboard.

  • Page 69: Fuse Replacement

    SUPPLY MODULE ENERGIZED, SINCE COMPONENT DAMAGE MAY RESULT. The input fuse for RFL 9785 power supply I/O module is located on the rear of the power supply I/O module. The fuse can be changed without removing the power supply I/O module from the chassis. To check and/or replace the fuse, proceed as follows: Place the POWER switch on the power supply I/O module to the OFF position.

  • Page 70: Corrective Maintenance

    RFL 9785, or in some other connected equipment. If the problem lies within the RFL 9785, use the schematics at the end of Sections 6 through 21 to try and determine which module is defective. Once this is done, replace the module; this should solve the problem.

    Figure 6-2 and the schematic diagram shown in Figure 6-4. 6.3.1 INPUT KEYING CONTROL LOGIC The 9785 AM Logic Module receives its input from the rear panel I/O and modules in the RFL 9785 terminal. It generates output for the transmitter and receiver detector modules based on switch settings and input signals.
  • Page 73 The receiver detector monitors the receive carrier signal strength, and generates a logic signal which is applied to edge connector pin A29 (SIG-COMP-IN) of the 9785 AM Logic Module. A logic-high SIG-COMP-IN or a logic-high CARRIER-SWITCH (indicating local carrier is active) will generate a block.
  • Page 74 If an under-voltage condition is detected by the power supply, the POWER-FAIL (A17) and/or POWERFAIL2 (C16) inputs to the 9785 AM Logic Module will be logic-low. Both signals in the logic-low state will generate a logic-low POWER signal to prevent a BLOCK function for the period of the under-voltage condition plus an additional 320ms.

    13.2 SEQUENCE OF EVENTS/IRIG-B MODULE 13.2.1 DESCRIPTION The RFL 9785 SOE/IRIG-B module is a status monitor card for the RFL 9785 which monitors input status every 1 ms. Events are recorded when any point changes state or if the CPU gets reset. The Sequence Of Events log is a record of the state of each point, the state of CPU reset, and the date and time the record was saved.

    75 Ohms 19.8.1 SPECIFICATIONS As of the date this manual was published, the following specifications apply to all RFL 9785 Skewed Hybrid Modules, except where indicated. Because all RFL products undergo constant refinement and improvement, these specifications are subject to change without notice.
  • Page 292 For this discussion, refer to the schematic diagram in Figure 19-21. The RFL 9785 Skewed Hybrid Module uses two hybrid transformers to couple signals between a transmitter, a receiver, and a line tuning unit. It provides impedance matching and signal separation, and prevents mutual loading and interference.
