Does the Neptune Tunze cable work on a P3?

[Macca_75]

Hi guys,

Does anyone know if the Neptune Tunze cable will work without modification on a P3?

Seems a nicer solution that using splitters, etc.

Hi,

Sorry, without modification, no.
Connector is not same same size (RJ45 vs RJ12) and not same pin order.

Apex pinout:
1 unused
2 unused
3 ground
4 10v chan1
5 unused
6 unused
7 ground
8 10v chanB

Profilux pinout:
1 +12V
2 10v chan1
3 ground
4 relay chan1
5 10v chan2
6 relay chan2

For Tunze, used pin are:
Apex: pin 3 & 4 for chan1 and pin 7 & 8 for chan2
Profilux: pin 3 & 2 for chan1 and pin 3 & 5 for chan2
