INSTALLATION AND OPERATION BXP6401-X-(XX) Installing the transponder antenna 1A032 The transponder antenna has to be fitted (outside) to the bottom of the aircraft at a horizontal, flat location. This location should not be in the “shadow” of air- craftstructure items. The highest range is achievied when the antenna is located at the lowest point of the aircraft fuselage.
(see Fig. 2-3 and Fig. 2-4). The related protocol is specified in the attachment document “Data Transfer Interface Protocol BXP 640X-XX-(XX)”. This manual is available at the Becker Product Support under the Article-No. 0590.258-071. Page 2-6...

INSTALLATION AND OPERATION BXP6401-X-(XX) Ref. to Controls and Description Function Fig. 3-1 indicators Button Push-button Push to jump from digit to digit for settings or from one menu to the next; generally used as an enter key Push-button Activates the Special Identifier (SPI) in ad- dition to the reply code for approx.
INSTALLATION AND OPERATION BXP6401-X-(XX) Start-up On power-up, the device starts. The software initiates circuits and performs PBIT. During that time the display looks as follows. Fig. 3-2 Start-up indication After the PBIT has elapsed and no error-message is shown in the display, the transponder switches to the mode set by the mode switch (A).
INSTALLATION AND OPE RA TION BXP6401-X-(XX) Flight le vel Flight le vel is dis play ed in ALT mode in the bot tom line of the dis play (al ti tu de = FL x 100 in ft): 4121 A L T Fig.
INSTALLATION AND OPERATION BXP6401-X-(XX) Negative results are indicated on the display with “FAILURE”. The transponder may be not switched into ON or ALT mode if any failure was found. The PBIT takes not longer than 1 second. If the test was successful, the XPDR switches immediately into the normal operating mode.
INSTALLATION AND OPERATION BXP6401-X-(XX) Aircraft Identification (AI or FN) With flight plan: The definition out of the flight plan: e.g. Flight Number or Company Call Sign Without flight plan (VFR): Tail Number (Call Sign) The indication of AI in the bottom line of the display is in mode SBY and ON only if selected in configuration menu.
INSTALLATION AND OPERATION BXP6401-X-(XX) Changing the flight number: Press SEL button (G). Rotate (B) until FN is displayed. Push (C) twice to enter the FN editing mode. Change the FN as described above. VFR code presetting Press the SEL button (G) to get into configuration mode (selection is indica- ted in the left bottom corner of the display under the operating mode indica- tion).
INSTALLATION AND OPERATION BXP6401-X-(XX) Flight operation in Mode A/C/S (reply code and altitude code) When ATC requests the transmission “squawk”, switch the transponder to ALT using mode switch (A). NOTES: This only makes sense if the transponder is connected to a coding altimeter.
INSTALLATION AND OPERATION BXP6401-X-(XX) VFR code activation Press the VFR push-button (J). The preselected code is then displayed. After 3 seconds, the displayed code gets active and overwrites the pre- viously-set reply code. Pressing push-button (J) again within 3 seconds reactivates the previ- ously-set reply code.
INSTALLATION AND OPERATION BXP6401-X-(XX) Configuration mode The configuration mode is available from SBY mode only. To get into configu- ration mode press button SEL (G), turn rotary encoder (B) until “CFG” appe- ars in the bottom row of the display. Available options are defined in the fol- lowing table.
