RF cable connection
Connecting the RF cable to the basic unit (SignalShark)
The RF cable has two connections:
• Control connection (1): for power supply as well as for the transmission of
compass data and control signals
• N connection (2): for transmitting the RF signal
Figure 3: Connecting RF cable: Control connection (1) and N connection (2)
Connect the RF cable:
1. Place the control cable plug of the RF cable on the control connector of
the basic unit (1), so that the red marking on the plug points upwards and
forms a line with the slot in the control connector.
2. Press the plug with the locking bush into the connection until the plug
lock is engaged.
3. Place the N connector plug of the RF cable on the N connector of the
basic unit (2) and screw down carefully the union nut and without tilting.
NOTE:
Make sure that the cable does not turn while screwing. Otherwise, the elec-
trical properties of the high-quality coaxial cable could be impaired by tor-
sional forces.
If you notice exceptional resistance while tightening, the union nut must be
loosened and realigned. Approx. 4 rotations are necessary to create a tight
connection.
Unscrewing the plug:
1. Unscrew the union nut (2) at the N connection.
2. Pull the control cable connector (1) on the ribbed plug head backwards
until the lock disengages.
