In the EDIT CONNECTION or NEW CONNECTION screen insert a unique name for the sensor.
Select the communications port that is connected to the DataStick.
Be sure to select the protocol, baud rate, parity and station number that matches the DataStick being connected.
Once the connection has been established, the display fields will be populated with current measurement data from the DataStick.
Pull-down windows will provide calibration, configuration and diagnostic choices specific to the sensor head that is connected to the
DataStick. Data logging options are available under FILE. Calibration, configuration and diagnostic choices are not available when
logging is active.

Open Protocol Commands
Open protocol ASCII commands are available with all communications adapters. The ASCII command set for the DataStick is available
for any application and the programming guide is detailed SECTION 7, “Commands and Responses”.
ASCII commands can be typed into any terminal program and with the correct communications setting; data can be obtained very quickly.
Communications setups vary depending on the protocol chosen. Some examples:
•
RS-232 ASCII: 9600 Baud, 8 data bits, no parity, 1 stop bit.
•
RS-485 MODBUS: Station address, baud rate, and parity.
These ASCII commands can be used directly with network protocols like Modbus or DeviceNet but it is much more effective to use the
standard maps for these protocols.
