lxnav LX DAQ Universal Analogue Data Acquisition Device (DAQ)
Important Notices
The LXNAV LX DAQ system is designed for VFR use only. All information is
presented for reference only. It is ultimately the pilot’s responsibility to
ensure the aircraft is being flown in accordance with the manufacturer’s
aircraft flight manual. The LX DAQ must be installed in accordance with
applicable airworthiness standards according to the country of registration of
the aircraft.

Packing list
- 1x LX DAQ
- 1x Terminal block plug 10pin
Installation
Connecting LX DAQ
Wiring
LX DAQ connects to RS485 BUS through D-Sub 9 connector to main instrument which also powers it.
External sensors are connected via 10pin terminal block connector located on
opposite side from D-Sub 9 connector
Pin names (from left to right):
- +12V Supply for sensors (output)
- +12V Supply for sensors (output)
- GND
- Input 1 (AIN1- input)
- Input 2 (AIN2- input)
- Input 3 (AIN3- input)
- Input 4 (AIN4- input)
- GND
- Not in use (Do not connect)
- GND
Connecting sensors
- Maximum input voltage for analog input is 12.0V on any of four channels.
The following example illustrates how to connect sensors.

Measuring ranges
Vacuum tightness
- Yes
Output signals
Load in Ω
- 4 .20 mA: (power supply- 10 V)/0.02 A
- DCO. 10V: 5k
- DC 1.5V: 2.5k
- DC 0.5..4.5 V : >4.5 k
Voltage supply
Power supply
The power supply depends on the selected output signal
- 4 .20 mA: DC 10…36 V
- DC O. 10 V: DC 14 … 366V
- DC 1 …5 V: DC 8.. 36V
- DC 0.5..4.5 V: DC4.5…5.5 V
Accuracy data
Accuracy at reference conditions
- Maximum: S +1 % of span
- Including non -linearity, hysteresis, zero offsets and end value deviation (corresponds to measured error per lEC 61298-2).
- Non-linearity (per IEC 61298-2)
- Maximum : s20.4 % of span BFSL
- Typical: +0.25 % of span BFSL
Temperature error at 0 … 80 °C
- Mean temperature coefficient of zero point: Typical s 0,15 % of span/10K
- Mean temperature coefficient of span: Typical s 0,15 % of span/10K
Settling time 2 ms
Long-term stability
Typical: s 0.2 % of span/year
Operating conditions
Ingress protection (per IEC 60529)
The ingress protection depends on the type of electrical connection.
- Circular connector M12 x 1 (4-pin): IP67
- Metro-Pack series 150 (3-pin): IP67
- AMP Superseal 1.5 (3-pin): IP67
- AMP Micro Quadlock (3-pin): IP67
- Deutsch DTO4-3P (3-pin): IP67
- Cable outlet: IP69K
The stated ingress protection only applies when plugged in using mating connectors that have the appropriate ingress protection.
Vibration resistance
20 g (per IEC 60068-2-6, under resonance)
Shock resistance
500 g (per IEC 60068-2-27, mechanical)
Temperatures
Permissible temperature ranges for:
- Ambient: -40… +100 °C
- Medium: -40.. +125 °C
- Storage: -40… +100 °C
Process connections
Sealings
The sealings listed under “Standard” are included in the delivery.
CDS system
All process connections are available with the CDS system. The diameter of the
pressure channel is reduced in order to counteract pressure spikes and
cavitation (see fig.1).
Materials
Wetted parts
Stainless steel
Non-wetted parts
Highly resistant glass-fiber reinforced plastic (PBT)
