I am trying to connect St40 to my C140W via the 140W is 24volts
Can the ST40 run from the 140W seatlk power or do i need to provide its own supply ?
What voltage do i need to connect to the seatalk 24 or 12 ?
Hi Richyrich06,

SeaTalk is only ever 12v, even though the C140W is running off 24v, so you will need a provide an external 12v suppy to the ST40 for SeaTalk.
