Figure 19: Connection to the transceiver.
NOTE:
There are 8 pin plugs with different pin numbering for pin 7 and pin 8. The
P4
dragon
needs an 8 pin plug with U-shaped contact footprint. Plugs with circular footprint don’t fit or
can only be attached to the
P4
dragon
with damaging force! Do not blindly rely on the printed
numbers on the plug. The connections as shown in the manual should be used as reference.
The 8 pin DIN socket is designed in a way that a 5 pin DIN plug (180
°
) may be plugged into it
too. It is possible to use a 5 pin DIN plug if an 8 pin is not available, or when balanced
operation is not required. For unbalanced operation, all switched must set to ON.
If a 5 pin DIN plug is used, then the connections are as shown:

Pin 4: Audio input from the receiver to the
P4
dragon
(loudspeaker or appropriate AUX socket).
Pin 5: Optional power supply input.

Note: All cables described herein are only useable for unbalanced operation. This
means all internal switched must be set to ON! See chapter 6.2.1 for details.
6.3 Transceiver Remote Control connection
The
SCS
P4
dragon
is equipped with a connector for controlling many common modern
amateur radio transceivers. Virtually all newer transceivers from KENWOOD, ICOM,
YAESU, SGC and R&S allow remote controlling of various functions via a serial interface.
Depending on type and manufacturer, almost all the transceiver parameters can be read out and
changed. For example frequency, filter, operating mode and much more can be controlled.
With radio equipment that is digitally controlled the list of functions is almost unlimited.
The
P4
dragon
uses this features in conjunction with the controlling PC software mainly to set
the frequency of the transceiver. You find more about the transceiver remote control in chapter
TRX in the main manual.
