switches to headphones and de-activates the internal loudspeaker. The volume for the loudspeaker and for
the headphones respectively is controlled through the regulator as shown under
point 5
.
The jack as shown under
point 7
(Illustration 1-4) is to provide the connection to the transmitter of radio
headphones, which are available as an accessory.
1.3.2 Plug-in connector
On the right-hand side of the case (see Illustration 1-3,
point 4
) you will find the connections and keys as
Point 1
shows the BNC connection for the aerial. The aerial of the correlator has
to be fixed here. F.A.S.T. supplies an aerial ex works (art. no. 5437D) with BNC connection and a 90° BNC
angle (art. no. 5441D) so that the aerial can be arranged orthogonally to the ground.

Point 2
in Illustration 1-5 shows the reset key of the correlator box. If any errors or interferences occur
during the measurement process which are due to malfunctions of the correlator box, the device can be reset
by pressing the reset key. In order to do so, just disconnect all external power supply from the jack as shown
in Illustration 1-5 under
point 3
; we recommend also to switch off the laptop. Then press the reset key for
5 seconds and reboot the system.
Point 3
shows the jack for the power supply. Here both the charger and the 12 volts power supply can be
connected to the device. As the power supply for the entire case is slightly more complex, the power supply
for the case is described below separately.
1.3.3 Power supply
The correlator can be operated in two ways concerning power supply. One option is operation with
accummulators, the other option is power supply through external sources. For the latter, the 12 volts power
cable as shown in Illustration 1-6 is used. The 12 volts plug marked with
point 1
is plugged into the
lighter of the particular vehicle, and the plug marked with
point 2
is plugged into the corresponding jack
(see Illustration 1-5,
point 3
) at the correlator case. If the device is operated through the power cable, all
components, i.e. both the laptop (if supplied by F.A.S.T.) and the corralator box, are supplied with power,
and the corresponding LED on the control panel is lit (see Illustration 1-4,
point 1
) indicating that the
device is supplied with energy through the power cable. If this particular LED is not lit, the vehicle probably
supplies insufficent voltage. In this case, you may have to start the engine of the vehicle in order to generate
sufficient voltage.
