When installing the probe, there is a bit of a fiddle involved for those that are using all of the switch contacts.

Here are my recommendations:

1) if you use two or fewer switch inputs, please use pins 3+4 and 5+6 and set up your profile accordingly.  This will leave pins 7+8 available for the probe and you'll have no issues.

2) if you are using three switch inputs (gear, spoilers, cruise/climb), the cruise/climb switch and the Temp probe will share pins 7+8.  The switch should be set up "closed = climb".  You will have to connect the probe and switch wires together and then run a single wire into the green connector for the appropriate pin, because the connector is very small and will not accept a pair of wires.  Gary @ CNi can supply you with a screw  type connector to accomplish this task, or if you are handy you can do it with solder and heat shrink.  I suggest not trying to do this on a windy morning at the airport before flying!

G'day Evan,

I presume that you select 'None' in the CNv Utility 2.1 program when 'assigning' a function for the OAT probe installation?


Cheers,

The OAT always goes on pins 7&8, profile setup has no effect on this.

If you have a C/C switch installed on 7&8 as well, what happens is that CNv reverts to OAT estimation based on lapse rate & altitude when the switch is closed.  At the moment, the estimation is based on what ever manual setting is applied on the ground.  In a future release, it will be based on the last recorded OAT measurement (plus lapse rate * altitude change).
