Figure 2: Connection to the transceiver.
NOTE:
There are 8 pin plugs with different pin numbering for pin 7 and pin 8. The PTC needs
an 8 pin plug with U-shaped contact footprint. Plugs with circular footprint don’t fit or can
only be attached to the PTC 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 the extra functions are
not required.
If a 5 pin DIN plug is used, then the connections are as shown:
