Hi
I need to install a BMV-712 display in a location that has a cable run length of 50ft from the shunt. I see from previous posts that extending beyond 10M is not advised. However a local representative said that Victron sell RJ12 cables up to 30M for this exact purpose. Can someone please let me know what the maximum RJ12 cable length is for the BMV-712.
Thank you.
Hi @PMarine, we designed and tested for the cable length that comes with the BMV: 10 meters. Thats the official answer: max length 10 meter.
A longer cable might work, or might not. Or it can depend on the amount of interference, longer cable will have more interference. Another possible is issue is more voltage drop, so less accurate voltage reading.
I've seen quite a few on 20 metre houseboats that appear to be working OK. As for 100% accuracy ... anyone's guess but if the display is up front at the helm it's much more likely to be heard or seen.
