1 Description
The flightDAQ is a self-contained acquisition system and combined pressure scanner that acquires
and transmits data to a host via Ethernet or a CAN bus all contained within a heated box. It is a variant
of the popular Chell MicroDaq pressure acquisition system that has been subjected to enhanced
testing in line with the expectations of flight test environmental conditions. Full details of the tests are
available on request.
The flightDAQ comes in several variants to accommodate both conventional HD series scanners and
Digital Thermal Compensation (DTC) scanners with 32 and 64 channels. The flightDaq2 features an
SQDC quick disconnect coupling for the measurement lines meaning a wide variety of tubing types
can be connected to it. Other pneumatic interfaces are also available.
The flightDAQ contains all the necessary valving to control the internal scanner valve for re-zero and
purge operations.
The flightDAQ has within it an embedded web server for configuration and data review. It can also be
used with the MicroDaqX software to display and log the data to disk. For data synchronisation, the
flightDaq2 features IEEE 1588 PTPv2 time stamping and a hardware trigger.
All electrical connections are made to the flightaq2 through one connector. To make connecting up
easier, Chell can supply a cable and interface with standard connectors on it (RJ45 for Ethernet, D
type for CAN and BNC for hardware trigger).

2. Installation and Interconnections
Consideration must be given to the installation location of the product. The product is heated so
must be installed in a manner allowing heat dissipation though conduction with the outer case or
convection. The product will not operate and will power-down once the internal temperature reaches
100 degrees centigrade.

Power supply return is internally bonded to the product case. EMC ground may be made via the
product mounting flange.
Hot plugging the power to the flightDAQ at the
connector can cause permanent damage to the unit.
Always switch the power at the power supply source.
2.2. Mounting Holes.
The FlightDAQ2 has 4 mounting holes suitable for a M6 bolt or stub. It is advisable that all these
holes are used in service.
2.3. Earthing
One of the four mounting holes will have been masked during the anodizing process to make it
conductive. It is always recommended that the FlightDAQ2 is connected to a good ground but
grounding this mounting hole.
Note: The connection pinouts for the flightDAQ-INT interface adapter can
be found at the end of this document (Section 7).
