Will the Fuse LEDs on Lynx Distributor illuminate without the 4-pin cable supplied with unit?

Trying to use the Lynx Distributor (and Power In) without the Lynx Ion Shunt or BMS (using BYD batteries). I had assumed the Fuse LEDs would illuminate with a working fuse in place and powered, however a line on the old Victron Live page for DC Distribution Systems suggests that this small data cable is used to power the LEDs (rather than taking power from the busbar itself). I cannot get the LEDs to illuminate - are the LEDs useless unless using the Lynx Shunt? Because Lynx Shunt uses CANbus, it cannot be used in conjunction with BYD on a CCGX (though I think VGX would support it).

12 volt to 5 Volt regulator - small and inexpensive on Amazon, used with the 4 pin short RJ11 cable supplied with the distributor: use pin out in below response for connections

Hi; indeed: it needs the RJ11 cable. There is no wide input (8 to 70VDC) power supply inside the Lynx Distributor

Thanks Matthijs, bit of a shame. What voltage does the LED control board require?

5V (4,5V-5,5V).


RJ11 connector:

Pin 1 is 5V

Pin 4 is gnd

Hello,

as far as I can see on my own distributor (2019), the connector is of type RJ9 (aka 4p4c) and not RJ11 (aka 6p4c). The pin numbers remain valid.

When all is OK, only the central led is green ; when a fuse has blown (or is missing) the central and circuit's leds are red.

Just finished making this work, I cut the RJ11 cable in half and striped the shield back to get at the yellow, black wires in side, the positive 5 volt goes to the yellow wire and the negative goes to black, I used the DC step down converter regulator in the above post from amazon, it fits inside the case of the distributor on the right side so is now a part of the distributor and works great!

Is a RJ11 or RJ9 on the Lynx Distributor ?

The answer to, your question is already here in this thread multiple times.

It’s a Rj10 connector! in the UK!

I have a Cerbogx with extra usb ports, wonder if I can power the LED board on my lynx distributor with an RJ11 to usb cable...

@midsummerenergy @mvader (Victron Energy) Confirming that I was successful in powering the Lynx distributor LEDs using the Cerbo GX.

The CerboGX has one USB port that cannot transit data (closest to HDMI port). I built a USB adapter using the supplied cable that came in the distributor box and spare usb A cable.

USB red to Victron (RJ9) yellow

USB Black to Victron (RJ9) Black

Nice work.

I have a related post under Lynx Shunt no LEDs.

Q1. Which of the two (2) RJ11 ports on the Lynx Shunt should this cable be plugged into?

Q2. Should there be any voltage on any of the other pins (other than Pin 1? (as above)
