Hi guys I'm looking for a 9 volt on a Lx3400 Compool panel - I believe that would be the voltage of a com port - any ideas ?

The current com port is being used for the control panel - i need an additional one.

Link to the manual
Page 12 has the board schematic on it

your help is much appreciated

TY

Com ports are not singular.. You can connect several things to the same com port..

I have an EasyTouch, and my pump, my SWCG, and my ScreenLogic remote.. are all connected to the same port.

Thanks,

Jim thank you sir - Quick follow up question - I have a Compool (not an easytouch) and my comport has a flat cable and a connector at the end (looks like at least)
are you saying i should splice wire and tap into the red/black for 9V ?
or is there a connector that i can buy that splits the red/black ?

TY so much for this

here is the cable wire i have connected to my comport

494,

Well.. I was "assuming" that the com ports were the same.. ☹ But the EasyTouch com port is only 4 wires...

We don't want to blow anything up, so let's see if we can get some input from Tom... Calling @ogdento ...

Thanks,

Jim R.
 
Hey guys,
apologies for the delay... i don't have one of those boards. but that the comm port on those has 6-conductors seems strange. i assume it's using rs-485, so maybe it's doing a 4-wire (full duplex) vs the 2-wire (half duplex) that pentair boards use (the power and gnd would be 2 extra wires, so 6 total).

what are you actually trying to do? just pull 9v for something, or connect another device that needs the comm lines as well? don't cut any wires and splice based on color - you need to know the pinout of that comm connector first.

btw... the manual says there are 2 connectors on each control panel to allow daisy chaining

It looks like you can use an RJ12 splitter and then an RJ12 Cable to get power as shown in the above reference.

What are you trying to power?

Red and black should be the power wires.

Check the voltage with a multimeter to see if it is what you need.

You should be able to splice into the wires for power as long as it's not going to anything that requires any significant current. In other words, it's just communication duty and not actuator duty.

Thanks guys the reason I neef the 9V is because I am testing a new Wi-Fi controlled board that will ultimately replace my spa side 4 button switch. I donot need to control actuators or other stuff with it.

Thx im going to have to find that 2 connector and use it.. Would u happen to know the pinouts to color mapping or help me ID the pins pls.
 
Just get the rj12 splitter and two short rj12 connector wires.

For one wire, cut off one end and expose the wires. Strip the red and black wires.

Unplug the existing rj12 connector from the board and plug it into the splitter.

Connect the uncut rj12 wire to the splitter and the board.

Connect the cut wire to the splitter and check the voltage on red and black.

You should be able to find the splitter and wires locally or at the link I posted or at another online store.

Or, just cut into the wires and check the voltage from red to black. If it's 9 volts, you should be good to go. Just tie into those wires.

I think that the adapter in the earlier reference is this, which shows the wiring.
