How to connect battery V-TAC to Ekrano GX with VE.Can?

Hello, I have an Ekrano GX and a Multiplus II 48/10000. This devices are connected with a V-TAC VT48100E-P2 battery.
I used a RJ45 wire to connect the battery and the Ekrano by VE.CAN, but my Ekrano does not detect anything.
I tried to change the speed (Kbits), and I already plugged the VE.CAN RJ45 terminator.
Maybe the RJ45 wire are not the same kind, I don’t know..

Do you have any idea ?
Thank you

I tried to solder the pin n°7 (CAN H, GX Side, White/Brown) to n°6 (CAN H, V-TAC, Battery, green) and pin n°8 (CAN L, GX side, brown) to n°5 (CAN L, V-TAC, Battery, White/Blue). But the Ekrano GX doesn’t not detect my battery..

you need a cable that connects pins 7&8 of the erkano CAN port to pins 6&5 of the BMS port. Also the ground pins should be connected, but don’t have the reference to hand at the moment. Did not find a reference to CAN speed, but the BMS looks similar to that used by pylontech so suppose 500kbit/s. you could also try the Victron CAN/BMS lead for the pylontech.
