(e.g. item TSUB21-NC). This manual provides only specific information needed for the FireStingO2-Mini-ST. It is highly recommended to study carefully the manual of the USB-device FireStingO2... -
Page 5: Safety Guidelines
When used in the field, the environmental conditions (like high humidity, dust, exposure to direct solar radiation) may cause damage or interference of the FireStingO2-Mini-ST, which is on the user's authority. - Page 6 Before using the FireStingO2-Mini-ST and its sensors, read carefully the instructions and user manuals. In case of problems or damage, disconnect the instrument and mark it to prevent any further use! Consult PyroScience advice! There are no serviceable parts inside the device. Please...

Page 7: Overview
3 Overview Fig. 1 provides an overview of the FSO2-MINI-ST. The overall dimension of the module is 67 x 25 x 25 mm (without the optical port). Two M3 threads can be found at the bottom for mounting the module in customized setups. Please note, that one of the M3 threads is hidden below the type label. - Page 8 Fig. 1 Drawing of the FSO2-MINI-ST...

Page 9: Supplementary Internal Sensors
3.2 Supplementary Internal Sensors Besides the very oxygen sensor, the FireStingO2-Mini-ST provides three other built-in high precision sensors: (1) An internal atmospheric pressure sensor for measuring the ambient air pressure, (2) an internal sensor for measuring the relative humidity of... -
Page 10: External Temperature Sensor
(useful for the following oxygen units: %air sat, %O2, µmol/L, mg/L). 3.3 External Temperature Sensor The oxygen measurement is generally temperature dependent. Therefore, FireStingO2-Mini-ST provides built-in temperature compensation, which should be activated if the temperature changes during measurements more than ca. 1ºC. - Page 11 4-wire PT100. The front cap provides a small cable feedthrough where the cable of the external PT100 can penetrate the housing. When closing the housing again, ensure that the solder points do not get into contact to the aluminum housing. NOTE: In order to minimize potential electrical noise coupling into the external temperature sensor, the 4-wire cable should be twisted and as short as possible.

Page 13: Connector X1: Power + Digital Interface
4.1 Connector X1: Power + Digital Interface The pin configuration of the connector X1 is given in Tab. 1. Pins 1- 3 are for power supply of the module. The transmit and receive pins of the UART-interface are given at pins 4+5. The additional pins 6+7 are only needed if the module should be operated in auto- mode (see following chapter). -
Page 14: Connector X2: Analog Output
4.2 Connector X2: Analog Output The connector X2 provides 4 independent analog outputs with a range of 0-2.5V DC at a resolution of 14 bits (Tab. 2). The 4 analog outputs can be configured by the UART communication protocol very flexible. The parameter given at each analog output can be chosen (e.g. -
Page 15: Operation Via The Uart-Interface
5 Operation via the UART-Interface FireStingO2-Mini-ST is operated via a standard UART interface at 3.3V levels (5V tolerant) consisting merely of a receive and a transmit line (connector X1, pins 4+5, see Tab. 1). The configuration of the UART-interface is as follows:... -
Page 16: Auto-Mode
text-command via the UART interface. The measurement results can be either read out via the same UART interface. Alternatively, measurement results can be also read from the analog output. For further details please refer to the separately available communication protocol. 5.2 Auto-Mode In the full-control mode each single measurement has to be triggered by a specific command sent via the UART interface (e.g. - Page 17 Thus, a fully configured module can be operated in auto-mode even if the power supply is intermediately interrupted. A typical application scenario would be the following: the FireStingO2-Mini-ST could be configured and calibrated in a "calibration lab" using the full-control mode (or the windows software Pyro Oxygen Logger).

Page 18: Operation Via The Usb-Interface Cable
FireStingO2-Mini-ST with a usual Windows PC, the USB-interface cable FSO2-MINI-USB is available from PyroScience. It includes a license for the comfortable oxygen logger software Pyro Oxygen Logger. Especially for initial testing purposes this logger software can speed up OEM-developments significantly. All special features (including the analog output and... -

"Oxygen Logger" can be found on the desktop • connect one end of the USB-interface cable FSO2-MINI- to the connector X1 of the FireStingO2-Mini-ST • connect the other end to an USB-port of the PC. The optical port of the FireStingO2-Mini-ST... - Page 20 Mode… (advanced settings, allowing also "triggered auto-mode") and configure the auto-mode in the respective dialog windows. Such a configured module can be now used in several ways. The simplest way would be to operate the module in the auto-mode (see previous chapter). But even for using it in an OEM-application under the full-control mode can make sense, because the communication protocol for simply triggering the measurements and for reading the results is much more straightforward to...
