I get plenty of enquiries about the Belfryboy clone logger, so I hope this page will answer any questions that you may have.

1. Davis Weather Wizard III Serial Port Connection. Started by BraveSirRobbin, Apr 07. Does anyone know the pinout to a DB-9 connection? I looked at Davis Instrument's site with no luck. Thanks, BSR Back to top #2 Dan (electron) Dan (electron). This is a bummer as the cost of the data logger/serial connection is almost the same as the cost.
2. That was until SLOweather pitched in and started selling ready to go serial adapters based on the console logger pinout. It is nice to know that this discovery enabled a cottage industry to spring up, though it must be said that it is an extremely small cottage. The second criticism was that my hack did not have a data logging feature.

Access, store and graph your data with WeatherLink. Add USB Data Logger to your Vantage Vue/Vantage Pro2 console or Weather Envoy, and view data on your PC with WeatherLink Computer Software (included) or online at WeatherLink Cloud solutions: WeatherLink.com and WeatherLink Mobile Apps (iOS and Android).

The Belfryboy clone logger was born from the need to get my weather station back on-line after it suffered a lightning strike. Some effort went into researching the interface and with a little time I was able to build the first prototype. I was then approached by various people asking if I could build one for them.
It works with the following Davis vantage pro models;

• Davis Vantage Pro
• Davis Vantage Pro2
• Davis weather Envoy
• Davis Vantage Vue

It has the same logging abilities as the original Davis logger, and can be used with many third party weather hardware/software combinations, including but not limited to;

• Weather Display very versatile software costing $70 to license and free evaluation period.
• Cumulus excellent donationware, very nice looking, and ready to use web templates .
• Meteohub miniaturized weather server design to run on low power computing options.
• Meteobridge low power device enabling data to be shared on public weather network.
• WeeWX Linux based weather display software.

Mostly I am asked do I still make them? The answer to that is 'yes'. I make them to order for whoever wants them and ship them worldwide for £50 plus £9 postage. Just use the PayPal button at the bottom of this page to buy one.

Another question is 'can I make one myself?' Of course you can! You can buy the bare boards direct from OSH park and buy all the parts and you too could have a Belfryboy Clone logger. If you are building your own logger and have a new console (firmware version 3.+) you'll need to program the dataflash chip to enable it to work, otherwise the console will report 'incompatible logger' Details of how to program it are to be found here.

Instructions on how to install the logger can be found here. And I have a useful logger set up program here, with instruction for use posted on WXforum.

Getting data from serial port to USB drive

QUICK START

1. Set your transmit unit to 9600 baud, 8 bits, no parity bits, 1 stop bit. Disable flow control, if necessary.
2. Plug dogcatcher into transmit unit. In general, use a straight cable, or see Pinout section for details.
3. Power the dogcatcher with the power supply included in the kit or with DC voltage between 8 and 30 volts.
4. Ensure green LED is blinking or on, which means power is good. If the LED is not blinking and you used your own power supply, ensure that you did not reverse power and ground.
5. Plug in memory stick.
6. Any time the red LED is not solid on, you may remove and / or replace the memory stick.
7. The data may be read from the stick by any computer with a USB port. Introduction.

INTRODUCTION:
The Dogcatcher is a serial data logger. It is designed to be easy to use without configuration. Data is stored on a standard memory stick. The serial port is set to industry standard 9600 baud, 8 bits per character, no parity, one stop bit. The Dogcatcher is designed for use where the a computer would be insecure, too expensive, too large or impractical.

OUTPUT FILE
Data is written to the USB stick exactly as it is received over the serial port. Tab delimited data remains tab delimited. Comma separated data remains comma separated. Images and other binary files will be uncorrupted. Because the Dogcatcher is not aware of the type of data passing through it, the user must rename the output file, CAPTURE.TXT, to the type of file sent.

SPECIFICATIONS

• Input voltage: 8VDC-30VDC
• Input current: Internally fused at 0.75A. Actual current draw depends on memory stick used.
• Communication settings: 9600 baud, 1 stop bit, no parity, no flow control. RS23 standard voltages.
• Writes data after 64 bytes received, or 7 second timeout between received bytes.
• Flash drive must be formatted for the FAT file system with a cluster size of 512 bytes. The majority of flash drives satisfy these requirements. Security enabled drives are not supported.

LED Blink Codes

Green LED

Solid off – No Power

Slow blink – Unit powered on, no flash drive detected. Flash drive needs to be formatted for FAT file system with a cluster size of 512 bytes. The majority of flash drives satisfy these requirements off the shelf. Security enabled drives are not supported.

Solid on – Flash drive is detected. Dogcatcher is ready to log data.

Red LED

Solid on – Data file on flash drive is currently open. DO NOT REMOVE FLASH DRIVE at this time or data loss is guaranteed and file system corruption is possible. Approximately 7 seconds after the Dogcatcher stops receiving data the file will be closed and you can remove the flash drive.

Rapidly blinking – Data has been sent and buffered, but there is no recognizable flash drive present. Data will continue to be buffered until a flash drive is inserted. If the 13kB buffer overflows, the oldest buffered data discarded in favor of newer data.

One blink and pause – Data buffer has been overrun. This could happen if there is something wrong with the flash drive, or the flash drive is badly fragmented. It is recommended that the flash drive is blank.

Two blinks and a pause – Flash drive is full.

Three blinks and a pause – Flash drive or CAPTURE.TXT is set to read only.

Serial Data Logger Software

Five blinks and a pause – Communications error. Try replacing the serial cable from your equipment to the Dogcatcher. If necessary use a shielded cable. Also ensure you are set to 9600 baud, 8bit data, 1 stop bit and no parity.

Davis Vantage Vue Data Logger

Six blinks and a pause – Please do not place the Dogcatcher too close to sources of electrical noise. If the unit is not close to any sources of electrical noise, please contact Brigantine Electronics for a replacement unit.

Serial Data Logger Hardware

Seven blinks and a pause – Hardware error; power cycle the unit. Free download lagu ariel tatum jangan marah mp3. If problem persists, contact Brigantine Electronics for a replacement unit.
