1 Description
1.1 Introduction
The Chell FlightDaq-TL is a complimentary product to our existing line of
FlightDaq and Q-Daq pressure measuring equipment.
Using the powerful architecture and interfaces enables the FlightDaq-TL to
accurately measure a large variety of input types, convert the measurement to
engineering units and then output the data over a number of configurable
Ethernet interfaces. These interfaces can be the Chell protocol (TCP/IP or
UDP), IENA, iDDS or NetScanner® simulation mode.
The FlightDaq-TL consists of 16 x 8-pin Lemo® 1B series inputs each of which
contain two inputs (one primary and one secondary), switchable excitation and
a digital interface for the optional Smart Lemo® plugs.
The 16 inputs can be individually configured to provide measurements for the
following:
• Voltage (one differential, one single-ended)
• Resistance
• Thermistor
• Thermocouple inputs (using external cold junction such as a Smart
Lemo®).
• RTD385
• Amplified pressure transducer
• Ratiometric pressure transducer
The FlightDaq-TL can be configured for any combination of channels without
comprising speed or performance (with the exception of the 24V excitation
which must be applied to all channels).
Configuration of the inputs and the output stream is carried out via an embedded
web server, using commands over the selected protocol or via an iDDS
configuration server by XML file download.
The user can choose between a number of standard in-built look-up-tables
(RTD385, N-Type etc) or enter their own for conversion to engineering units of
their choice (maximum size 448 lines - downloadable from a CSV file).
Alternatively, if used with the compatible Smart Lemo®’s, this LUT can be stored
in the connector and therefore remains physically tied with the transducer.
The FlightDaq-TL has a programmable excitation source available to all
channels. This can be configured to be +5, +10 or +24VDC.
The FlightDaq-TL features PoE as standard but can be user configured (via
internal switches) for conventional DC supply.
This manual supports V1.0.8 of the FlightDAQ-TL firmware. If using a unit with
earlier firmware, some documented features may not exist or function as
described here.

4 Channel Configurations
4.1 Introduction
The FlightDaq-TL is a highly configurable scanner and as such, each input (with
some restrictions) can be configured as a different input type without any effect
on performance.
Each channel has two inputs which can be configured for four different ranges
(±78mV, ±300mV, ±5V and ±10V). In addition, excitation can be provided on pin
1 (for resistance and ratiometric ranges) and pin 2 for 24 volts excitation. In
addition, a digital grade 5V is available on pin 7.
For popular channel configurations such are RTD’s and thermocouples, there
are defined inputs types with the appropriate ranges pre-configured and the
correct engineering unit applied to the outputs.

4.3 Thermocouple Inputs
The FlightDaq-TL can only measure thermocouples when used in conjunction
with the Chell Smart Lemo®. The Smart Lemo® forms the cold junction of the
thermocouple by crimping the thermocouple alloy to copper tubes. The
temperature of this junction is then measured by a 10kΩ thermistor which is
bonded to the copper tubes. There is an (optional) internal memory within the
Smart Lemo® which can carry the calibration of the thermocouple and/or the
thermistor.
For all thermocouple ranges, the primary input is set to ±78mV to measure the
hot junction and the secondary input is set to 5V which, when combined with the
excitation will measure the output of the thermistor.
The results from the two inputs are converted to temperature by using the
appropriate NIST look-up-tables for both the hot junction and the thermistor.
This is all configured automatically when the thermocouple input is selected.

Additional Features
Cold Junction Heater
The FlightDaq-TL, when combined with the Smart Lemo®, has a built-in
thermocouple cold junction heater which is used to check that the polarity of the
thermocouple is correct. The heater is enabled via the web server and will apply
a current to a heating resistor bonded to the cold junction for 15 seconds. The
user can then determine if the polarity of the thermocouple is correct.
Hot Junction Polarity Reversal
As part of the channel configuration, the polarity of the hot junction can be
reversed if it is found to be incorrect by the above test.

5 FlightDaq-TL Configuration Webserver
5.1 Introduction.
The FlightDaq-TL features an Ethernet interface that is used for configuration
and data output. Data output can be the Chell standard protocol (via TCP or
UDP), IENA (over UDP) and DDS. Most protocols support configuration as well
as data output so that the operation of the unit can be modified in use.
For initial configuration and demonstration, the FlightDaq-TL has an inbuilt web-
server which provides an easy to use and powerful interface to the FlightDaq-
TL.
The webserver is divided by tabs into five areas of functionality, namely 'Setup’,
'Live Data', ‘Channel Configuration’, ‘Advanced’, and ‘Factory Tools’.
'Setup' provides the means to set FlightDaq-TL’s main operating parameters
such as data streaming rates and device comms addresses.
The unit's function may be checked and demonstrated using 'Live Data' to show
the raw readings and FlightDaq-TL’s calibrated output.
‘Advanced’ provides setup for the all other more advance parameters that may
require configuration on a per application basis.
‘Channel Configuration’ allows to user to configure each of the 16 channels for
the correct input types.
‘Factory Tools’ provides some lower level configuration. This tab is password
protected and therefore not readily available to everyone and further detail is
beyond the scope of this document.
