Serial to USB adapter and driver For Davis Vantage Pro 2

[rexross]

I have a MacBook Pro running Sierra (OS X 10.12.2) and a Davis Vantage Pro 2 with a data logger.

My old Keyspan USA-28GX serial to USB adapter used to interface from the Davis to the Mac no longer works.

I am looking for a suggestion to either:

1.  Provide an updated driver for the Keyspan

or preferably

2.  Suggest a modern serial to USB adapter plus driver.

Surely others must have faced this and I would appreciate any suggestions.  Thanks.

Dear Rex and WeatherCat trying to keep up with new technology types,

I am looking for . . . . .

2.  Suggest a modern serial to USB adapter plus driver.

Most of us have stations with built-in USB so this need is getting a bit rare.  However a little searching on Amazon brought up this model:

https://www.amazon.com/CNCT-Serial-RS232-Adapter-Light/dp/B01N5J84PO/ref=sr_1_2?ie=UTF8&qid=1484778576&sr=8-2&keywords=serial+to+usb+mac+sierra

According to the description there are drivers for the latest version of OS X macOS available on the manufacturer's website.  At under $10, it doesn't look like too risky a purchase.

Let us know what you discover so we can help the next person with this problem!

Cheers, Edouard

I'm very surprised to hear that most people have built in USB with their weather stations.  I have a couple of Davis Vantage Pro 2 systems which are a couple of years old.  They do not. The Davis data logger is a peculiar device and needs a serial to USB converter.

Perhaps Davis has upgraded that recently.  While I don't think so, I'll check.

The serial interface you recommended does, unfortunately, not have the proper ports.

Anyway, I continue to use my old Keyspan USA-28XG and I have found a Sierra compatible driver for it.  That is:

USA-19HSdrvr_10.9_10.10_10.11_v4

While it shows OS X 10.11 as the latest, it works fine with 10.12

Bought mine back in March of 2015. It has a USB port, but I think the cable is just to get the data into the computer via its USB port, since Mac's never had serial ports. There is still a need for a USB driver that makes the data available to whatever software you might be using. I am operating from memory since I can't find the specifics at Davis' site although I think I found it on their old one. It may be part #8434.

Davie sells data loggers with either USB (#6520) or Ethernet (#6555) connections.

Thanks.  Good to know Davis may be upping their game a bit.

If I lose serial connection  in the future will look into the new data ports from Davis.

Fortunately, all is running well now on both my stations.
