I just replaced my Davis Vantage pro2 after 10 years use, I got a new Davis Vantage Pro2. So I decided to update all my equipment and tower. I had the old Temperature/Humidity semsor in a stevenson screen, And just run the cable up through the stevenson screen top and plugged it into the ISS. It worked fine, But as I have built a new stevenson screen, I would like to run the cable out the back of the louvers and up over the top of the stevenson screen to plug into the ISS. But the cable is to short to do this, Does anyone know if Ican get and extension cable and joiner to extend the temp/hum sensor cable. I would only need to extend it by less than half a metre. I did try a 2 metre straight through cable and joiner, But it through my temp out and humidity stopped working on my console. I am not sure if the ext cable is wired wrong or just to long at 2 metres. Any help would be appreciated. I will post some pics tomorrow.
I don’t know about the temperature/humidity cables, but I’ve extended my anemometer, solar and UV cables by about 6m to put them at the top of a mast and the transmitter nearer the bottom so that I don’t have to lower the mast to replace the battery (if I need to) and also to reduce the wind loading caused by having the transmitter at the top of the mast.
The T/H sensor uses a digital data signal unlike the anemometer/solar/UV which are all analogue voltages, so it cannot be extended to the same lengths. But it should be fine at a couple of metres.
The temp/humidity sensor uses 6 core cable which i got from RS when i extended mine by a couple of metres when i separated it from the sensor suite you also need gel connectors Davis used to do these but arrear to have stopped but RS do them or you may find on eBay
Thanks for the replys, I will order a 1m 6 core cable and a joiner today. Will post if it all works ok.
