SCHEMATIC AND WIRING DIAGRAMS
TASK 34-50-96-810-804-A01
1. Introduction
A. This section shows the maintenance aid and schematic diagrams for the TDR94/94D
ATC/Mode S Transponder.
TASK 34-50-96-810-805-A01
2. Modification History
A. Table 2001 shows the causes for changes to the TDR-94/94D. This data helps the technician
to know the cause for a service bulletin and gives the changes done to the equipment.
SERVICE BULLETIN REASON/DESCRIPTION
1-12 Factory-installed on all units.
13 Converts the -003 status Class 2A Mode S transponder to a -004 status
Class 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 Extended
Mode S squitter (termed "ADS-B").
• Provisions for the reception of Special Category I (SCAT-I) Differential
Global 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 may
cause uncommanded transitions to the STANDBY mode when the
TDR-94/94D is interfaced with Gables Control Units operating in the
BURST mode. When in the STANDBY mode and the AIR/GROUND
#2 discrete (J1-27) changes from "on-ground" to "in-air," the unit may
reply to interrogations while continuing to indicate that the unit is in
STANDBY mode. This modification reprograms CPU I/O Circuit Card
A5 to correct this problem.
15 In some installations the TDR-94/94D may cause interference with VHF
Comm reception when the transmitter is tuned to 120 MHz. Installation
of this service bulletin reduces electromagnetic emissions from the
TDR-94/94D Transponders. The modification adds 31 jumper wires to
Video Processor circuit card A6, 687-0726-004/005.

TDR-94, PART NO 622-9352
SERVICE BULLETIN REASON/DESCRIPTION
16 In aircraft which parallel the CSDB/ARINC429 Control Select and Burst
Enable inputs to other systems, removal of transponder power may
cause unrequested activation of the function in another system.
The dual diode isolation provided by Service Bulletin No. 12 reduces
noise margin for the selection circuits. In cases where the aircraft
provision for mode selection also includes an isolation diode, this
margin becomes inadequate for reliable operation. This service bulletin
changes to a single isolation diode to restore the noise margin to an
acceptable level.
TDR-94 Transponder (CPN 622-9352-004/005) and TDR-94D
Transponder (CPN 622-9210-004/005) already contain this modification
by design. Installation of this service bulletin in the -004/005 statuses
only updates the marking indicating SB 16 is installed.
17 Installation of this service bulletin corrects a subtle error in the status
indications of some altitude replies. The actual altitude reported
is correct at all times. Gillham (gray code) altitude sources have
100 foot resolution. However, the transponder will set the altitude
resolution status to indicate 25 foot resolution when connected to a
Gillham altitude source. The altitude resolution status is set correctly
for aircraft that have digital source of altitude information. It is highly
recommended that aircraft with Gillham-based altitude encoders install
this service bulletin.
18 In TDR-94 Transponders, installation of this service bulletin converts the
non-diversity TDR-94 Transponder to the diversity capable TDR-94D
Transponder. Diversity capability allows the transponder to utilize
two antennas, one each on the top and bottom of the aircraft. TCAS
requires diversity transponders.
In TDR-94D Transponders, installation of this service bulletin adds the
service bulletin marking which may be required since current production
units are marked with Service Bulletin 18.
19 The -004 and -005 versions of the TDR-94D may cause the Change 7
version of non-Rockwell Collins TCAS systems to produce a TCAS flag,
or intermittent TCAS flag, when the TCAS is in the Standby mode. This
service bulletin installs new software in the TDR-94D that improves the
robustness of the TCAS Change 7 data bus and improves compatibility
with non-Rockwell Collins TCAS units.
The formatting of Flight ID data is updated to comply with the ARINC
718-4 definition.
The correct processing of the Gillham altitude 100-foot resolution bit
originally addressed by Service Bulletin 17 is also incorporated.

SERVICE BULLETIN REASON/DESCRIPTION
20 The -004 and -005 versions of the TDR-94D may cause the Change 7
version of non-Rockwell Collins TCAS systems to produce a TCAS flag,
or intermittent TCAS flag, when the TCAS is in the Standby mode. This
service bulletin installs new software in the TDR-94D that improves the
robustness of the TCAS Change 7 data bus and improves compatibility
with non-Rockwell Collins TCAS units.
The formatting of Flight ID data is updated to comply with the ARINC
718-4 definition.
The correct processing of the Gillham altitude 100-foot resolution bit
originally addressed by Service Bulletin 17 is also incorporated.
21 The -006 version of theTDR-94/94D may cause the Change 7 version
of non-Rockwell Collins TCAS systems to produce a brief intermittent
TCAS flag. The fault is normally recovered automatically and may not
be seen by the operator.
The transponder may intermittently report a "C1" or "C2" Squitter fault
that will cause some non-Rockwell Collins control heads to change
to a standby state.
This service bulletin installs new software in the TDR-94/94D that
improves the robustness of the TCAS Change 7 data bus to improve
compatibility with non-Rockwell Collins TCAS units and incorporates
improvements to the Squitter self-test circuitry.
22 In some installations the TDR-94/94D may cause interference of VHF
reception when transmitter is tuned to 120 MHz. Comm squelch
breaks at 120 MHz have been identified in installations with minimum
transponder/comm isolation. Installation of this service bulletin will
greatly reduce potential interference with VHF Communications.
23 All fielded -007 status TDR-94 and TDR-94D units do not display JTSO
approval . This service bulletin replaces the nameplate with one that
allows usage in European airspace.
24 This service bulletin replaces obsolete synthesizer circuit cards
687-0724-001/002 with 687-0724-003 when there is a need that
warrants replacement of the card.
25 This service bulletin replaces IF receiver circuit card A7 and the IF
receiver cover if U107 fails on the circuit card.
26 U413 on synthesizer circuit card A4 is replaced to improve a
temperature-related power-up problem on unit delivered during
February through May of 2005. These units may not power up correctly
after exposure to temperatures of -55rC or below. This condition may
also occur if unit power is cycled in mid-flight at extreme altitudes.

SERVICE BULLETIN REASON/DESCRIPTION
501 This modification converts -004, -005, and -006 status TDR-94/94D
units to -007 status units by reprogramming Processor circuit card A5
and replacing one EPROM. The -007 status TDR-94/94D is compliant
with European requirements for Elementary and Enhanced Surveillance
for SSR Mode S operation. This capability allows the transponder to
process aircraft Flight Identification inputs and to support expanded
ground station Surveillance Identifier (SI codes). In addition, the new
capability also provides:
• Changes TDR data output bus label 200 so that altitude
data 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 ARINC
429 control inputs and Gillham inputs, the altitude is no longer
used when the ARINC control input is lost.
502 This modification converts the -007 status TDR-94/94D units to -008
status units by replacing CPU I/O Processor circuit card A5. Video
Processor circuit card A6 is also modified by removing one capacitor
and adding a jumper wire. Current -007 units do not provide source
selection required for PL4/21 installations. Conversion of -007 status
units to -008 status unit will provide the enhanced surveillance required
in 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 status
units, CPU I/O Processor circuit card A5 is replaced. On -008 status
units, various hardware changes are made.

maintenance aid diagram can look different than the circuit card/assembly.
SUBTASK 34-50-96-810-008-A01
C. Schematic Diagrams
(1) The schematic diagram helps the technician isolate a fault in a circuit to a defective
component. Where applicable, circuit voltages and test points are shown. The
schematic diagram shows the most correct electrical configuration at the time of print for
the manual. Refer to the schematic changes page shown before the maintenance aid
diagram for all changes made.
SUBTASK 34-50-96-810-009-A01
D. Configuration Effectivity
(1) Table 2002 shows the revision level (at the time of print) of circuit cards or subassemblies
of the TDR-94/94D that have a schematic diagram. Figure numbers for the maintenance
aid and schematic diagrams are also shown.
(2) Rockwell Collins uses the procedure that follows to identify the configuration (or revision
level) of a unit or subassembly.
(a) A 2-letter (maximum) identifier is shown after the letters REV (revision). If no
changes have been done, the identifier starts with - (dash). The first change is

identified as A, the second as B, and continues through Y, then to AA, AB, and
continues 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 Collins
for repair, or removed from the company's available units. At the time of rework, the
unit or subassembly is identified with the revision level mark (letter) of the changes
made. When done, the original mark is left on the unit or subassembly and the
letters RWK (rework) are added. This is followed with the letter identifier of the
newest 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 at
revision 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 unit
with the same identifier. This unit does contain changes necessary to
make the unit operate the same as a new unit with the same identifier.
A unit reworked to a specified revision identifier can look different
from 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 identifiers
on the schematic changes page. Table 2002 can show a list that includes the
newest revision or other revisions. When this occurs, the schematic shows the
revision identifiers given on the Schematic Changes Page and can also show the
newest revision identifier.
