Data Connection
Data from the ES-600 and connected SM-module can be received by a computer via RS-232
serial cable. Basic communication parameters are listed in the table to the right. For more
details
please
consult
the
www.ecosensors.com/support.
Serial data is updated from the SM-module approximately once per second. An example serial
data output stream is given below for 1 ppm ozone, 23 °C, and 33% relative humidity:
Ozone (ppb), Temperature (°C), and Relative Humidity (%):
1000, 23, 33
Analog Output Full Scale Selection
The full-scale range for the 0-2 V and 4-20 mA analog outputs may be
selected by adding or removing up to three push-on jumpers on header
J4, located on the back of the display circuit board. Access this area by
removing four screws from the display bezel.
Changing the analog output full-scale range will not change the ES-600
display, which will always read in the within range 00.00 to 99.99 ppm.
The actual measurement range of the ES-600 display is determined by
the attached SM-module. Refer to the specification sheet of the attached
SM-module to determine the measurement range.
The ES-600 is shipped from the factory with the Analog Output Full Scale
Range set to match the installed SM-module. For further details, refer to
the specification sheet of the attached SM-module.
