DATAIR-400/M3 ARINC 429 TESTER

1.4 Supplied accessories

The DATAIR-400/M3 Tester is supplied with a universal 110VAC/240VAC battery charger.

One ARINC 429 Test Lead pair for connecting to an ARINC 429 Tx system and one pair for connecting to an ARINC 429 Rx system. In addition there is a firmware update cable (D9 to

D9) for updating the firmware when new a new upgrade is available via our website.

1.5 Rechargeable battery pack

The battery pack is supplied partially charged for safety reasons during transit. The battery pack should be fully charged using the supplied battery charger prior to first use. This should take no longer than 3 hours. The expected life of the battery from a full charge is 8 hours.

The unit should not be operated during charging as this will greatly affect the charging procedure. However the unit can be run on an external 6V DC power supply if the battery pack is removed whilst it is being charged.

1.6 Keypad

The keypad is the method used to navigate the menu system, display selection of options and alpha-numeric data entry and comprises the following keys:

 Keys ⓿thru ❾ are for entering numeric data and also double for entering character entry.

 ENT key is for confirming the previous data entry.

 CLR key is used to abandon data entry and will usually return the user to the root of the menu.



↑↓←→

keys are used for navigating the menu and the various fields displayed on the LCD.

 The

└┘ key can be used to insert a space when entering character strings.

 The

+/-

is used to change the sign of an entered numeric value where supported. The polarity of certain ARINC 429 label data can only be changed by modifying the SSM field.

 The following keys are reserved for future use:

F1

thru

F6

and the SYM key.

 If you select an incorrect option then pressing the

←

key will move the Menu context back one level.

 Pressing the CLR key will always position the context at the root menu.

3.3.5.1 Entering values for BCD formatted words.

The “Sign” of an entered value for a BCD formatted words can be altered by pressing the +/key. This key will toggle the value of the SSM between ‘11’ and ‘00’. This key changes the polarity of entered values including other variations such as N/S E/W where appropriate.

PLEASE NOTE When entering values for BCD formatted words, the exact number of required digits must be entered.

If a BCD field is defined as 5-digits wide then five digits must be entered to avoid rubbish being entered.

When accessing a data entry screen for a selected Label, press the ENT key to begin editing.

For a 4-digit formatted field the initialised engineering field will be shown as “0000”. The user would enter 4-digits like “1234”.

If the BCD field were formatted as NNN.N then the user would still enter four digits –

WITHOUT entering the decimal point. For this field format entering “1234” would result in

“123.4”.

3.3.5.2 Entering values for BNR formatted words.

The “Sign” of an entered value for standard BNR formatted words can be altered by pressing the +/- key. This key will toggle the value of Bit-29 between a ‘0’ and a ‘1’.

Unlike BCD words above the user does not have to adhere to the number of digits entered.

If you require to enter a value of “123.4” then you would press ‘1’ ‘2’ ‘3’ ‘.’ ‘4’. The decimal point button is active for BNR entry.

3.3.5.3 Entering values for BNR “Special” formatted words.

In the ARINC 429 specification, there are defined words that have to be treated in a special case. Example Labels are Labels 150 (GMT) 260 (date), 310 (Latitude) and 311 (Longitude).

Label 150 : GMT has three fields defined, Hours Minutes and Seconds.

Access the label in the usual way. Enter a time of “012359” will result in “1: 23.59” being displayed. The

←→

keys allow individual editing of the Hours, Minutes or Seconds fields.

Label 260 : Date is similar to the description for Label 150 above.

Label 310 and 311: Latitude and Longitude.

These two labels are special in that they are defined as degrees / 180.

If the user enters “45.5” degrees and presses ENT key the value displayed will be

“N45.499920”. In order to change the “N” (“E” for L311) to a “S” (“W” for L311) the user must move the cursor to hover over Bit-29 (Sign bit). Entering a ‘1’ will result in the value changing to “S134.50024”

3.3.6 MODE: Setting the Transmitter mode

This menu option sets the mode of transmission. There are four possible modes:

1. Continuous transmission at the High speed rate, 100kbp/s

2. Continuous transmission at the Low speed rate, 12.5kbp/s

3. Single Shot at the High speed rate,

100kbp/s

4. Single Shot at the Low speed rate,

12.5kbp/s



Continuous transmission means that it continue until the transmitted is switched off.



Single Shot mode means that every time the transmitted is set to

“RUNNING” the transmitter will transmit one iteration of the currently enabled transmitter list and then stop.

3.3.7 TX IS: Starting / Stopping the Transmitter

This function sets the state of the transmitter to either transmitting or not transmitting.



If the Mode is set to “continuous” then the transmission will continue transmitting all enabled Tx labels until the transmitter is switched off. The transmitter state is toggled by pressing the ENT key.



If the Mode is “Single Shot” then each time the ENT key is pressed the transmitter will transmit one iteration of the enabled Tx Labels and then stop. The display will momentarily show “RUNNING” and then change back to “STOPPED”.

3.4 LOAD A DATABASE

This section loads the standard ARINC 429 Engineering Units Definitions files for Tx and Rx.

There can be a different database loaded for Rx and Tx. This section is also the entry point to for managing Profiles (see later section).

Using databases allows the user to interpret received data in meaningful engineering units formats such as Air speed in Knots, Altitude in Feet, etc. Otherwise the user would have to decode the raw binary data in order to decode the values. The same applies to entering real values for subsequent transmission.

The DATAIR-400/M3 is supplied with a compliment of standard definitions. Choose the definition in order to load the required definitions for your test requirements. For further information consult the ARINC 429 Specification. The “(ID:002)” shown in the screen refers to the loaded active definition.

3.4.1 PROFILES

Profiles are used to hold different configurations that may be required to be saved by different users. Databases for Tx and Rx and the Label list configuration (enabled Tx labels, etc.) are typically saved in profiles. This saves the user from having to set up the instrument each time they need to conduct a test. Options available are Load, Save, Clear and Clear All

Profiles. When saving a new Profile the alpha-numeric keypad can be used to save a meaningful name (ie FMCU Test).

3.5 Custom Label Definitions

In addition to the standard engineering units databases contained with the DATAIR-400/M3 the user may also customise the standard labels or create custom definition where a standard definition is unavailable. Customising a standard Label may be required when the width of the data field or the value of the field needs to be altered.

Once a custom Label has been created it can be made ‘Active’ so that it has priority over the standard definition. The custom Label can also be suspended so that the Standard Label become active once again.

If the custom Label is not required for future use then it can be permanently deleted.

4.0 Performing a Firmware update

You will need to download the program “STMicroelectronics flash loader.exe” from our website at: http://www.yed.com/Downloads/stm32-stm8_flash_loader_demo.zip

Locate this program in a folder of your choice.

This program will load the update file into the FLASH memory on the DATAIR-400/M3.

This utility will run on a PC and will allow the reprogramming of the STM32F103 processor firmware with firmware e-mailed or downloaded from our website. This feature alleviates the necessity of a customer having to return their hardware to YED in order to have the firmware updated or modified under contract. The down load utility requires the use of an RS232 serial port on the host PC and this can include any suitable USB Serial port adapter.

Connection between the PC and the DATAIR-400/M3 unit is via the supplied D9 to D9 cable.

Procedure for updating the firmware is as follows:

1. With the DATAIR-400/M3 powered OFF, connect the cable end marked “DAT400” on the D9 connector back shell to the DATAIR-400/M3 and the other end to your RS232 port.

2. Switch the unit to ON

3. Start the “STMicroelectronics flash loader.exe” utility and continue with the process below.

The first screen after executing the utility will be as shown below:-
