6. g O2 provides up to 4 oxygen channels together with a single temperature port Therefore an automatic temperature compensation of the oxygen channels is only possible with one common temperature sensor The has been developed to enable individual temperature compensation for each oxygen channel by offering additional temperature ports The temperature ports can be used in combination with the standard temperature sensors available from PyroScience The has been designed for a tight mechanical coupling with the oxygen meter FireSting O2 as it fits smoothly to the bottom of the FireSting O2 where it can be fixed by integrated screws Both the TeX4 and the FireSting O2 are connected via USB cables to windows PC The coupled modules are operated by the FireSting Logger software 2 Safety Guidelines The TeX is a laboratory instrument intended for combined usage with the fiber optic oxygen meter FireSting O2 In order to guarantee an optimal performance of the TeX please follow these operation instructions and safety guidelines Before starting the measurements please ensure for e proper installation of the FireSting Logger software before connecting the TeX for the first time to the USB port of your PC e appropriate operation temperature 509 and humidity non condensing conditions If any problems or damage evolve please disconnect the instrument immediately mark it to prevent any further use and consult Py
7. lashing of the logo indicates a proper connection e Start the FireSting Logger software The software should show immediately the following dialog window An uncoupled temperature extension module TeX4 was detected Should this TeX4 be coupled to the used oxygen meter Firesting O27 This will enable independent temperature compensation for each oxygen channel using the 4 temperature ports of the TeX4 xe e Click Yes Now the TeX4 is programmatically coupled to the specific FireSting O2 indicated by the message Coupled to TeX4 visible below the FireSting Logger logo in the main window The coupling information is stored within the flash memory of the TeX4 Therefore at the next startup of the FireSting Logger software the coupling is automatically detected by the software 7 5 3 Usingthe FireSting Logger software The operation of a FireSting TeX4 couple with the FireSting Logger software is widely unchanged compared to the operation of a sole FireSting device Please refer to the manual of the FireSting Logger software for general operation instructions The temperature channels of the TeX4 are automatically activated if Temperature Sensor is chosen in the settings of a specific oxygen channel Settings gt Environmental Conditions in the Sample Temperature Sensor For example if the user selects Temperature Sensor for the oxygen channel 3 then the temperature reading for this channel is not taken

9. no handshake The baud rate can be changed by a special command of the communication protocol refer to the communication protocol for further information However after power cycling the module always reverts to the standard baud rate of 19200 In the following different operation modes of the extension port are described 7 1 Full Control Mode The standard operation mode of the module is the full control mode The necessary electrical connections are shown in Fig 5 3 5 5 0 VDC a 5 5 o 4 bE l c c lt wc pe GND GND 1 Pin assignment in full control mode The full control mode allows exploiting the full functionality of the module Each action of the module is triggered by transmitting a text command via the UART interface The measurement results 13 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 7 2 Listening Mode In this mode the Firesting O2 is powered and controlled via the normal USB interface together with the versatile logging software Firesting Logger However the UART transmit pin of the extension port can be used to listen to the data stream by third party software In this mode only the pins 1 and 4 are used e K The data stream contains all sampled temperature dataina
10. o the PC After all FireSting and TeX devices have been coupled properly by this procedure all couples can be connected to a single PC The FireSting Logger software should then be started repeatedly for each couple which opens a separate logging window for each couple The Flash Logo button in the main window can be used to identify the FireSting TeX4 couple connected to a specific logger window Clicking this button will cause a short flashing of the FireSting logo followed by a short flashing of the status LED of the TeX The coupling information is stored within the flash memory of the TeX4 Therefore once the coupling has been performed it will be valid even if the coupled devices are connected to a different PC 5 5 Uncoupling a FireSting from a TeX4 If a formerly coupled FireSting device should be operated without the coupled TeX4 device you just have to start the FireSting Logger software without having the TeX4 device connected to the PC 10 6 Analog Output The TeX provides at the backside of the housing analog outputs at the connector with 5 pins Extension Analog Port Out This connector provides 4 independent analog outputs with a range of o 2 5V DC at a resolution of 14 bits The 4 analog outputs can be configured very flexible within the TeX4 settings window Pin Name Function Description 1 GND Ground 2 AO_A Analog Output Analog Output Port A 0 2 5 V DC 14 bit reso
