2.3 OPERATING FREQUENCIES VS ICAO CHANNEL DESIGNATORS
For all test frequencies listed in test setups in this report, the ICAO Channel Identification
developed for the 8.33 kHz channels is used. The channel identification will not
necessarily reflect the actual operating frequency. Table 4.7-1 shows the relationship
between ICAO Channel Identification, actual operating frequency, receiver bandwidth,
and ARINC 429 frequency control word. NOTE: Narrow Band (NB) is selectivity for
8.33 kHz channels and Wide Band (WB) is selectivity for 25 kHz channels.

5.3 STANDARD ARINC 429 BUS/DATA CONFIGURATIONS
5.3.1 Standard Control Data Configurations
5.3.1.1 VHF-4000
All test steps are performed using continuous tuning on the low speed ARINC 429 control bus
429_Input_Port_B (Pins 3 and 4). The control words are labels 030 for 25 kHz channels & 047 for 8.3
kHz channels.
Calibration and TFM parameters are set using the high-speed maintenance input bus MAINT_IN (Pins 9
and 10) and output port MAINT_OUT (Pins 13 and 14). The control word is label 277 (See Appendix for
format).
5.3.1.2 VDL-2000
All test steps are performed using continuous tuning on the high-speed ARINC 429 maintenance input bus
429MAINT_IN (pins 1 and 32). The control words are labels 030 for 25 kHz channels & 047 for 8.3 kHz
channels.
Calibration and TFM parameters are also set using the high-speed ARINC 429 maintenance input bus
429MAINT_IN (pins 1 and 32). The control word is label 277 (See Appendix for format).
5.3.2 Standard Data Configurations
• The “Standard 25 kHz ARINC Configuration” is defined as follows:
Octal label 047 (8.33 kHz label) set to NCD.
Transmit the control data on label 030 (Oct) every 200 ms.
The tuning channel will be defined at the time of reference to this definition.
The SSM is set to 11 (squelch disabled).
SDI set to 00 (All call).
• The “Standard 8.33 kHz ARINC Configuration” is defined as follows:
Octal label 030 (25 kHz label) set to NCD.
Transmit the control data on label 047 (Oct) every 200 ms.
The tuning channel will be defined at the time of reference to this definition.
The SSM is set to 11 (squelch disabled).
SDI set to 00 (All call).
5.4 TEST SEQUENCE
If the UUT has never been aligned then all alignment steps must be performed in sequence. For re-
alignment of UUT as a result of a repair action or modification, perform only alignment steps of circuits
that have been effected by repair action or modification. Checksum will be automatically updated
whenever FLASH memory is updated.

6. Alignment
Connect main connector plug from test station to UUT.
Apply 27.5 ± 0.5 Vdc to the power input.
VHF-4000, power pins 58, 64 and ground pins 59, 65.
VDL-2000, power pins 10, 11 and ground pins 8, 9.
Wait 30 seconds for the unit to complete power on testing.
The VHF4000 or VDL2000 may be aligned per Section 6.3 Alignment Procedures or with the automatic
alignment system (CATS-21) executing DGS-005.
6.1 SOFTWARE LOAD PROCEDURE
Load the desired top-level software using the data loader capability of the VHF-4000 or the boundary scan
interface.
6.2 CALIBRATION AND TFM PARAMETERS
The VHF-4000 uses electronic alignment for circuits that use values for various parameters stored in
FLASH memory. TFM parameters are those that require different values depending upon temperature,
frequency or mode. Calibration parameters are those that are the same for all temperature, frequency, and
mode.

Appendix A Alignment Formats
The ARINC 429 Label 277 Diagnostic Request input word is defined as follows:
Bit(s) Function Contents
8-1 Label 277 (octal) 11111101 (binary)
27-9 Request Parameters Request Type specific (see below)
29-28 Sequence Number Indicates position in sequence of Request Words
31-30 Request Type 31 30 Definition
0 0 Software Version Request (Deactivated in VHF-4000)
0 1 Memory Access Request (Program, Data, or Serial
EEPROM)
1 0 Alignment Data Request
1 1 Diagnostic Data Request
32 Parity Bit Set for odd parity
The ARINC 429 Label 277 Diagnostic Request input word is used in conjunction with the ARINC 429
Label 351 Diagnostic Response output word. The Label 277 word is intended to be compatible with the
VHF-422 legacy radio’s Label 277 Bench Test Request word and will be used only on the ARINC 429
Diagnostic Data Bus.
Since read requests require up to two input Label 277 words to complete and write requests require up to
four input Label 277 words to complete, the Sequence Number field is used to specify which word in the
request is being used. For example, a Memory Access word requesting a write to Program memory
requires an input sequence of three Label 277 words. The first word has a Sequence Number of 00b and
specifies the Memory Type as “Program”, the Access Type as “Write”, and provides the required Write
Access Code (i.e., a password for enabling Memory Access writes). The second word provides the 16-bit
address within Program Space Page 1 (i.e., internal DSP RAM) of the memory location to be written and
will have a Sequence Number of 01 (binary). The third word provides the data to be written and will have
a Sequence Number of 10b. The Write Access Code in the first word of the three-word Memory Access
write request sequence is a key to prevent write access to memory by anyone but the manufacturer.

Every Label 277 input word will be answered with a Label 351 output word that contains a Response Type
that corresponds to the input Label 277 word’s Request Type and a Sequence Number that reflects the input
Label 277 word’s Sequence Number.
The form of the Request Parameters field for each Request Type supported via the ARINC 429 Diagnostic
Request input word is defined in the following table. In the Alignment Data requests, bits 24-27 of word
00 in the sequence are always used, regardless of the operation being requested. A write request via a
Label 277 input sequence (including Memory Access write requests, Alignment Data write requests, and
Diagnostic Data write requests) will have no effect if the VHF-4000 unit is not in Alignment Mode. Bit 27
of the Label 351 word(s) output in response to input Label 277 Alignment Data requests indicates whether

Appendix C - VDL Mode 2 Operation
The BFR test message is a VDL Mode 2 message containing 249 application bytes. The message will also
contain 6 Reed Solomon check bytes for a total of 255 bytes. The normal VDL preamble containing the
following segments must also be contained in the message:
a) 12 bits (4 symbols) for transmitter power ramp up;
b) 48 bits (16 symbols) for synchronization
c) 3 bits as the reserved symbol
d) 17 bits transmission length
e) 5 bits header FEC.
Refer to DO-224A, “Signal-in-Space Minimum Aviation System Performance Standards
(MASPS) for Advanced VHF Digital Data Communications Including Compatibility with
Digital Voice Techniques”, September 13, 2000, for specific details on the composition of
VDL Mode 2 message and waveform.
A suitable test message is shown in hex format as follows :
The message starts with 000 hex which is 12 bits (4 symbols) of constant signal which is
the ramp up for VDL Mode 2.

For any transmit or receive tests in VDL Mode 2, the unit must first be placed in VDL
Mode 2:
1) Ground the Voice/Data Discrete
2) Transmit 0008001D#, 8000235E# on CMU Port A input. This message must be sent at a
rate of at least once a second to maintain VDL Mode 2 operation.
3) Monitor CMU output bus for a label 270 message. Bits 20 – 24 show the mode status of the
radio, the status should be 0010.
4) Transmit 47000315# (ALO) on CMU Port A input.
5) Monitor CMU output bus for a label 270 message. Bits 20 – 24 show the mode status of the
radio, the status should be 0110.
6) Transmit D2050015# (Mode_Set.request) on CMU Port A input.
7) Monitor CMU output bus for a label 270 message. Bits 20 – 24 show the mode status of the
radio, the status should be 0111.
8) Transmit D201F115# (Pr_Set.request) on CMU Port A input.
9) Monitor CMU output bus for a label 270 message. Bit 11 should be set to 1 and Bit 14 11
should be set to 1 (Protocol Reset State).
10) Transmit one of the operating frequencies below on CMU Port A input.
11) Monitor CMU output bus for a label 270 message. Bit 11 should be set to 0 and Bit 14 11
should be set to 1 (Protocol Set State).
To set desired operating frequency in transmit and receive send the following
message on the CMU Port A input for the desired frequency:
