@aardvark: This has been explained previously, but let me repeat: VP2 ISS; 6332; 6372; 6382 transmitters ALL use the same board. The Davis parts list says:
7346.049 PCBA for Anemometer/Sensor Transmitter Kit OR Temperature Station OR Temperature/Humidity Station (US)
(The ISS PCBA is technically a different part number because it comes on the SIM backplate). The 6345 PCBA is the only VP2 transmitter board that's different.
When you tried the 6372, are you sure that you switched the transmitter type on the console to Temp/Hum and didn't just leave it on Temp?
NB Davis frontline support are, I'm afraid, not always 100% clued up - they seem to have a significant turnover of staff and the newer ones have been known to shoot from the hip when it comes to explanations.
I have done everything you recommended for the past 2 months. It doesn't work.
My first thought was that the temperature/humidity sensor was poached. So I have two of the 6382 units in the house, disconnected one and took it to this sensor, left it on and I got both the temp/humid readings. Then I hooked it back up to the 6372 sensor and same thing. Next was to be sure the dip switches were set right as well as the transceiver and they checked out.
So I went out to the yard, swapped out the two 6372's and started over, reset the dip switches to match what they were supposed to be and same thing, only the temperature side, in fact... if I have it set for the temp/humid sensor I get nothing, but if I set only the temperature, then I get temperature.
That indicated the sensor was fine, but... So I know it will cost me $72.00 plus loss of use to send the transceiver in to be repaired, so I called rather than waste money. I called and was told that they are different units. Perhaps you are blessed.
I could opt for the Davis 7345.976 - Wireless ISS SIM Board for PRO2 from Archer for 114 and be done with it. I know that works with just about everything. Run it on batteries or if I get adventureous put a Davis charger on it and go electrical.
For What I should do to put this to rest is copy down the board part number off the board itself. Maybe I'll do that in a bit. Grimm and Bluebloods are on tonight
