FIELD OF THE INVENTION
The present invention is required for initial calibration of all the parameters on the vehicle
during installation.
BACKGROUND OF THE INVENTION
The aircraft parameters can not be checked online with system integrated on
aircraft. To ease out the monitoring of parameters, a suitable apparatus is required.
The present invention is used for checking the Inter Face between the unit and the
vehicle like aircraft inputs. This unit will be required for initial calibration of all the
parameters on the aircraft during installation.
Further, the invention is also used for checking the outputs from the test connector
of the UUT (Unit Under Test).
SUMMARY OF PRESENT INVENTION
In accordance with one aspect of present invention is to provide Interface between
the unit and the aircraft inputs.
In accordance with yet another aspect of present invention is provided with a
capability to calibrate initially all the parameters on the aircraft during installation.
In accordance with yet another aspect of present invention is provided with a
housed in a plastic case with a lid and carrying handle.
In accordance with yet another aspect of present invention, the connection is
made to the UUT by two plugs, two sockets, 122 Voltage monitoring sockets and seven
current monitoring sockets. The cables of sockets & plugs are stowed in an open
compartment on one side of the present invention.
In accordance with second aspect of present invention is to provide compact test
equipment.
In accordance with another aspect of present invention is to provide easy test
procedure to test UUT.

DETAILED DESCRIPTION
Referring to Fig. 1, 2, 3 & 4, the present invention is a BIB/BOB test set use for
checking the Interface (I/F) between the UUT and the vehicle like aircraft inputs.
Break-in-Box (BIB) is required for initial calibration of all the parameters on the
vehicle like aircraft during installation. The block diagram of BIB is shown in Fig.1.
Break-out-Box (BOB) is used for checking the outputs from the test connector of
the UUT. The block diagram of BOB is shown in Fig.2.
The BIB/BOB (see fig.3) is housed in a plastic case with a lid and carrying handle.
The connectors are placed on the right hand side of the BIB/BOB box. The front view of
BIB/BOB is shown in Fig.4.
Break-in-Box (BIB):
Connection is made to the UUT by two plugs (PL1 & PL2), two sockets (SK1 &
SK2), 122 Voltage monitoring sockets 1 to 100 & 1 to 22 and seven current monitoring
sockets (SK3-SK9). Socket SK1 and plug PL2 are provided on approx. 1.5 m of cable;
plug PL1 and socket SK2 are provided on approx. 1 m of cable to enable to connect to
the vehicle system. The cables are stowed in an open compartment on one side of the
present invention. The voltage and current monitoring sockets are mounted on the front
panel.
Two switches on the front panel (SW1 and SW2) allow the said invention to be
operated in one of two modes (AIRCRAFT or TEST). Three test strips (TS1, TS2 & TS3)
and the printed circuit board is mounted on a back plate connected to the front panel by
four pillars. Access is gained to the PCB and writing by removing four small screws from
the left hand side of the front panel and three screws from the under side of the case.
Inputs to plug PL2 (pin 1-22) are connected to corresponding pins on sockets SK2 and
test sockets (1-22) on the front panel.
Break-out-Box (BOB):
Connection is made to the unit by plug (PL1) and socket (SK1) and 22 voltage
monitoring sockets (TS1 to TS30) on the front panel.
