kellerbus, a library for arduino

requirements

• Arduino IDE 1.0.1
• Time library for Arduino. http://arduino.cc/playground/Code/Time
• RS485 compatible transceiver, like MAX487
• compatible* Keller pressure transmitter/transducer

features

• read serialnumber
• read pressure P1/P2
• read temperature T/TOB1/TOB2
• read CH0
• read configuration (gain/offset)
• read device type/software version
• read calibration data (min/max pressure min/max temperature)
• read/write device address
• read/write device time
• read battery capacity
• supports softwareSerial or hardwareSerial

planned features

• read/write record configuration (DCX)
• read record (DCX)

how to install

1. download and copy the kellerbus folder to your Arduino library directory.
   on mac: /Users/username/Documents/Arduino/libraries
   Windows 7: C:\Users\username\Documents\Arduino\Libraries
2. restart the Arduino IDE
3. Select an example from the Examples/kellerbus menu
4. connect your compatible* Keller transmitter
5. upload your code to the Arduino and start the serial monitor

(*)compatible are transmitters with digital RS485 output eg Series 33X/35X/36X/39X/41X/46X/DCX
