ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352SCHEMATIC AND WIRING DIAGRAMSTASK 34-50-96-810-804-A011. IntroductionA. This section shows the maintenance aid and schematic diagrams for the TDR94/94DATC/Mode S Transponder.TASK 34-50-96-810-805-A012. Modification HistoryA. Table 2001 shows the causes for changes to the TDR-94/94D. This data helps the technicianto know the cause for a service bulletin and gives the changes done to the equipment.SERVICE BULLETIN REASON/DESCRIPTION1-12 Factory-installed on all units.13 Converts the -003 status Class 2A Mode S transponder to a -004 statusClass 3A/ADSB Mode S Transponder. This modification provides :• Enhanced TCAS operation (termed "Change 7")• Enhanced Mode S data link communications (termed"Class 3A" or Comm-C"• Provisioning for first step in free-flight via use of the ExtendedMode S squitter (termed "ADS-B").• Provisions for the reception of Special Category I (SCAT-I) DifferentialGlobal Navigation Satellite System data via a Mode-S uplink.• Three new ARINC 429 input data busses; GPS Data In (J2-49/50),FMS/IRS Data In (J2-27/28), and AIS/ADS Data In (J2-39/40)• Twelve new discrete input pins.14 A combination of high interrogation rates and self-test procedures maycause uncommanded transitions to the STANDBY mode when theTDR-94/94D is interfaced with Gables Control Units operating in theBURST mode. When in the STANDBY mode and the AIR/GROUND#2 discrete (J1-27) changes from "on-ground" to "in-air," the unit mayreply to interrogations while continuing to indicate that the unit is inSTANDBY mode. This modification reprograms CPU I/O Circuit CardA5 to correct this problem.15 In some installations the TDR-94/94D may cause interference with VHFComm reception when the transmitter is tuned to 120 MHz. Installationof this service bulletin reduces electromagnetic emissions from theTDR-94/94D Transponders. The modification adds 31 jumper wires toVideo Processor circuit card A6, 687-0726-004/005.Modification History Cont.Table 2001/Table 34-50-96-99A-012-A0134-50-96 Page 2001May 18/06
ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352SERVICE BULLETIN REASON/DESCRIPTION16 In aircraft which parallel the CSDB/ARINC429 Control Select and BurstEnable inputs to other systems, removal of transponder power maycause unrequested activation of the function in another system.The dual diode isolation provided by Service Bulletin No. 12 reducesnoise margin for the selection circuits. In cases where the aircraftprovision for mode selection also includes an isolation diode, thismargin becomes inadequate for reliable operation. This service bulletinchanges to a single isolation diode to restore the noise margin to anacceptable level.TDR-94 Transponder (CPN 622-9352-004/005) and TDR-94DTransponder (CPN 622-9210-004/005) already contain this modificationby design. Installation of this service bulletin in the -004/005 statusesonly updates the marking indicating SB 16 is installed.17 Installation of this service bulletin corrects a subtle error in the statusindications of some altitude replies. The actual altitude reportedis correct at all times. Gillham (gray code) altitude sources have100 foot resolution. However, the transponder will set the altituderesolution status to indicate 25 foot resolution when connected to aGillham altitude source. The altitude resolution status is set correctlyfor aircraft that have digital source of altitude information. It is highlyrecommended that aircraft with Gillham-based altitude encoders installthis service bulletin.18 In TDR-94 Transponders, installation of this service bulletin converts thenon-diversity TDR-94 Transponder to the diversity capable TDR-94DTransponder. Diversity capability allows the transponder to utilizetwo antennas, one each on the top and bottom of the aircraft. TCASrequires diversity transponders.In TDR-94D Transponders, installation of this service bulletin adds theservice bulletin marking which may be required since current productionunits are marked with Service Bulletin 18.19 The -004 and -005 versions of the TDR-94D may cause the Change 7version of non-Rockwell Collins TCAS systems to produce a TCAS flag,or intermittent TCAS flag, when the TCAS is in the Standby mode. Thisservice bulletin installs new software in the TDR-94D that improves therobustness of the TCAS Change 7 data bus and improves compatibilitywith non-Rockwell Collins TCAS units.The formatting of Flight ID data is updated to comply with the ARINC718-4 definition.The correct processing of the Gillham altitude 100-foot resolution bitoriginally addressed by Service Bulletin 17 is also incorporated.Modification History Cont.Table 2001/Table 34-50-96-99A-012-A0134-50-96 Page 2002May 18/06
ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352SERVICE BULLETIN REASON/DESCRIPTION20 The -004 and -005 versions of the TDR-94D may cause the Change 7version of non-Rockwell Collins TCAS systems to produce a TCAS flag,or intermittent TCAS flag, when the TCAS is in the Standby mode. Thisservice bulletin installs new software in the TDR-94D that improves therobustness of the TCAS Change 7 data bus and improves compatibilitywith non-Rockwell Collins TCAS units.The formatting of Flight ID data is updated to comply with the ARINC718-4 definition.The correct processing of the Gillham altitude 100-foot resolution bitoriginally addressed by Service Bulletin 17 is also incorporated.21 The -006 version of theTDR-94/94D may cause the Change 7 versionof non-Rockwell Collins TCAS systems to produce a brief intermittentTCAS flag. The fault is normally recovered automatically and may notbe seen by the operator.The transponder may intermittently report a "C1" or "C2" Squitter faultthat will cause some non-Rockwell Collins control heads to changeto a standby state.This service bulletin installs new software in the TDR-94/94D thatimproves the robustness of the TCAS Change 7 data bus to improvecompatibility with non-Rockwell Collins TCAS units and incorporatesimprovements to the Squitter self-test circuitry.22 In some installations the TDR-94/94D may cause interference of VHFreception when transmitter is tuned to 120 MHz. Comm squelchbreaks at 120 MHz have been identified in installations with minimumtransponder/comm isolation. Installation of this service bulletin willgreatly reduce potential interference with VHF Communications.23 All fielded -007 status TDR-94 and TDR-94D units do not display JTSOapproval . This service bulletin replaces the nameplate with one thatallows usage in European airspace.24 This service bulletin replaces obsolete synthesizer circuit cards687-0724-001/002 with 687-0724-003 when there is a need thatwarrants replacement of the card.25 This service bulletin replaces IF receiver circuit card A7 and the IFreceiver cover if U107 fails on the circuit card.26 U413 on synthesizer circuit card A4 is replaced to improve atemperature-related power-up problem on unit delivered duringFebruary through May of 2005. These units may not power up correctlyafter exposure to temperatures of -55rC or below. This condition mayalso occur if unit power is cycled in mid-flight at extreme altitudes.Modification History Cont.Table 2001/Table 34-50-96-99A-012-A0134-50-96 Page 2003May 18/06
ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352SERVICE BULLETIN REASON/DESCRIPTION501 This modification converts -004, -005, and -006 status TDR-94/94Dunits to -007 status units by reprogramming Processor circuit card A5and replacing one EPROM. The -007 status TDR-94/94D is compliantwith European requirements for Elementary and Enhanced Surveillancefor SSR Mode S operation. This capability allows the transponder toprocess aircraft Flight Identification inputs and to support expandedground station Surveillance Identifier (SI codes). In addition, the newcapability also provides:• Changes TDR data output bus label 200 so that altitudedata is always Gillham formatted.• Labels 275 and 276, containing the 24-bit ICAO address,are added to the TDR data output bus.• TCAS Sensitivity Level Command (SLC) is restricted to Uplink Formats(UF) with Designator Identification (DI) fields with either a 1 or a 7.• When utilizing Gillham comparison of altitude from ARINC429 control inputs and Gillham inputs, the altitude is no longerused when the ARINC control input is lost.502 This modification converts the -007 status TDR-94/94D units to -008status units by replacing CPU I/O Processor circuit card A5. VideoProcessor circuit card A6 is also modified by removing one capacitorand adding a jumper wire. Current -007 units do not provide sourceselection required for PL4/21 installations. Conversion of -007 statusunits to -008 status unit will provide the enhanced surveillance requiredin PL4/21 installations.503 This modification converts -007 and -008 status TDR-94/94D units to-108 status units, which will provide ADS-B capability. On -007 statusunits, CPU I/O Processor circuit card A5 is replaced. On -008 statusunits, various hardware changes are made.Modification HistoryTable 2001/Table 34-50-96-99A-012-A0134-50-96 Page 2004May 18/06

Themaintenance aid diagram also shows a history of the component configuration. Themaintenance aid diagram can look different than the circuit card/assembly.SUBTASK 34-50-96-810-008-A01C. Schematic Diagrams(1) The schematic diagram helps the technician isolate a fault in a circuit to a defectivecomponent. Where applicable, circuit voltages and test points are shown. Theschematic diagram shows the most correct electrical configuration at the time of print forthe manual. Refer to the schematic changes page shown before the maintenance aiddiagram for all changes made.SUBTASK 34-50-96-810-009-A01D. Configuration Effectivity(1) Table 2002 shows the revision level (at the time of print) of circuit cards or subassembliesof the TDR-94/94D that have a schematic diagram. Figure numbers for the maintenanceaid and schematic diagrams are also shown.(2) Rockwell Collins uses the procedure that follows to identify the configuration (or revisionlevel) of a unit or subassembly.(a) A 2-letter (maximum) identifier is shown after the letters REV (revision). If nochanges have been done, the identifier starts with - (dash). The first change is34-50-96 Page 2005May 18/06
ROCKWELL COLLINSCOMPONENT MAINTENANCE MANUAL with IPLTDR-94, PART NO 622-9352identified as A, the second as B, and continues through Y, then to AA, AB, andcontinues to YY. (Letters I, O, Q, S, X, and Z are not used).(b) Rework includes changes in a unit or a subassembly sent back to Rockwell Collinsfor repair, or removed from the company's available units. At the time of rework, theunit or subassembly is identified with the revision level mark (letter) of the changesmade. When done, the original mark is left on the unit or subassembly and theletters RWK (rework) are added. This is followed with the letter identifier of thenewest revision done during rework. For example, unit one has the mark of REV B -RWK F, and unit two has the mark of REV F. This shows that the two units are atrevision F, but unit one is reworked and can look different from the other.NOTE: A reworked unit may not contain all the changes made to a new unitwith the same identifier. This unit does contain changes necessary tomake the unit operate the same as a new unit with the same identifier.A unit reworked to a specified revision identifier can look differentfrom a new unit with the same revision identifier.(c) This section includes only letter revision identifiers that cause schematic changes.A unit or subassembly can have a letter identifier that comes between the identifierson the schematic changes page. Table 2002 can show a list that includes thenewest revision or other revisions. When this occurs, the schematic shows therevision identifiers given on the Schematic Changes Page and can also show thenewest revision identifier.SUBASSEMBLY/UNITSREVISION LEVEL COLLINS PARTNUMBERMAINTENANCEAID DIAGRAMSCHEMATICDIAGRAMHigh-Voltage PowerSupply Circuit CardA1L 687-0721-002 Figure 2001/GRAPHIC 34-50-96-99B-036-A01Figure 2002/GRAPHIC 34-50-96-99B-037-A01High-Voltage PowerSupply Circuit CardA1C 687-0721-003 Figure 2003/GRAPHIC 34-50-96-99B-038-A01Figure 2004/GRAPHIC 34-50-96-99B-039-A01Power AmplifierCircuit Card A2AA 687-0722-003 Figure 2005/GRAPHIC 34-50-96-99B-040-A01Figure 2006/GRAPHIC 34-50-96-99B-041-A01Power AmplifierCircuit Card A2K 687-0722-004 Figure 2007/GRAPHIC 34-50-96-99B-042-A01Figure 2008/GRAPHIC 34-50-96-99B-043-A01Assembly Revision Level and Diagram Reference Cont.Table 2002/Table 34-50-96-99A-013-A0134-50-96 Page 2006May 18/06
