Installation
3.3.1. Mechanical Installation
Due to its small size the Volkslogger can conveniently be mounted on an existing
camera bracket. This allows access to all keys and easy reading of the display during
flight. For attachment, the underside of the instrument case contains three holes with
M5
thread (metric, 5mm)
(Camera thread (1/4”-20) does not fit!!)
In case no camera bracket is available, the logger, due to its low mass, can also be
fastened with Velcro to the instrument console.
During installation, assure that the integral
antenna has a clear view of the sky
and is not
shielded by metal or carbon fiber parts
.
In case the instrument should be installed in the baggage compartment, attention must
also be paid to the “clear view of the sky”. (Caution: Carbon fiber or metal parts shield
the GPS reception, plastic and wood are usually not critical).
To prevent accidental operation of the buttons by moving objects,
the buttons can be
locked
. (Menu:
ACT.LCK
). During the time the buttons are locked, the input code for
unlocking them is shown on the display.
The statements for mounting instruments and antenna are also valid for instruments with
external GPS-Antenna.
3.3.2. Electrical Installation
Power supply and communication with PC or flight computer are achieved
simultaneously over a 8-pin Western-Plug (RJ-45) on the left-hand side of the
instrument. Either the PC-readout cable or the aircraft installation cable is connected to
it.
Caution is advised during connecting the plug of the cable.
Functions of the wires on the Logger Connection Cable:
brown and brown-white:
Positive wire of the power supply (+12V)
orange and orange-white:
Negative wire of the power supply and the data line
blue:
Data output (PC-Communication or NMEA)
green-white:
Data input (PC-Communication)
We remind once more about the necessary fusing of the supply voltage!
The instrument should be connected to the aircraft power circuit by a qualified technician.
The functions of the wires have to be strictly observed. Non-compliance may seriously
damage the electronics of the VOLKSLOGGER.
The operating limits given in the technical data are stated in order to avoid damage to the
instrument. The instrument is internally protected against polarity reversal.
Nevertheless, the proper polarity should be observed during connection.
