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). VDL-2000 5.3.1.2 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. ______________________________________________________________________ ______ 2000 Rockwell Collins, Inc Page 11 of 61 PTR for VHF-4000 and VDL-2000 Data Radios 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. SOFTWARE LOAD PROCEDURE 6.1 Load the desired top-level software using the data loader capability of the VHF-4000 or the boundary scan interface. CALIBRATION AND TFM PARAMETERS 6.2 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.

The Label 277 word is intended to be compatible with the VHF-422 legacy radios 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. ______________________________________________________________________ ______ 2000 Rockwell Collins, Inc Page 49 of 61 PTR for VHF-4000 and VDL-2000 Data Radios The number of Label 277 words required in the input sequence for each type of Label 277 diagnostic request is defined as follows:

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:
