Connecting vantagePro console to raspberry pi using serial interface

[Yash Naik]

Hello,

I am want read from VantagePro console into my raspberry pi using serial interface. Can someone tell me the connection I ll be needing to do. Sorry, I could only find the setup part after connecting to Serial or USB interface but there is nothing explaining how connection needs to be done.

Thanks,

Yash

If you are using the Davis serial datalogger?  You can use a serial to USB adapter and plug it into the Pi. This is the one that I use http://www.amazon.com/gp/aw/d/B00425S1H8/ref=mp_s_a_1_6?qid=1461675663&sr=8-6&pi=AC_SX236_SY340_FMwebp_QL65&keywords=serial+to+usb&dpPl=1&dpID=41mGSgm%2BDML&ref=plSrch

I am using Davis Weather Station console Vantage Pro 2 , is that the same thing?

All of the Davis consoles, as well as their "Envoy" product, are the same as far as their interface is concerned.

What is different is the "logger" that is plugged into them. There are 3 different types of loggers:

• 06510USB: USB interface
  
• 06510SER: Serial interface
• 06555: IP interface

You must have one of these. They are about $150USD. Any of them will work with weewx, but the first two tend to be more reliable. 

I sympathize. Davis does a very poor job of explaining this.

you might have a look at the daughter cards from this company:

https://www.abelectronics.co.uk/

for example, they sell the 'serial pi plus':

for some applications this is *much* better than messing with a serial-usb cable (e.g., on a pi zero)

That is correct I have the Serial interface and IP interface data logger. IP interface was unreliable and therefore we are switching to either Serial or USB to collect our data values and get it into the Pi.

Currently,we are using WeatherLink software to log to our database the weather station values from the Vantage pro station using the IP logger. Since, that is proving to be unreliable we are moving to use the Pi and connect to our database. I hope this move improves the reliability.

Thank you for your quick responses.

If you have the serial interface (part 06510SER), then you will need either

• A serial-to-usb converter. These are easily obtained at many electronics stores, but their quality varies widely. 
• A daughter board for your RPi, as Matthew suggested

What kinds of problems do people have with the Davis IP data logger? I probably shouldn't say this publicly but I've been running one for over a year with zero problems. It is on an isolated network, just a cable from the Raspberry Pi to the data logger.

The problem is that they took a highly stateful protocol, which was designed to be run over a low-latency, reasonably reliable serial connection and extended it out over a network. The driver manages what state the console is in (sleeping, emitting LOOP packets, dumping archive records, dumping selective archive records, etc.). If there is a network problem in the middle of all that, it can be a challenge to figure out what state the console is in.

By contrast, well-designed network protocols are stateless. You make a request and get a response, and that's that.

If you are using the WLIP logger over a LAN it will probably work fine, but even then, some users have had problems. Consider yourself lucky! :-)
