more or less self-explanatory and provides utilities, graphic & tabular display for set-up, calibration, logging etc. These functions are easily accessed without
deeper knowledge about the sensor. SSC 2
Q: Many new PC's do not have a serial port. How can I communicate with the sensor without this?
A: The only way to communicate with the sensor is through the serial port. There are adaptors available that convert from USB to serial port. Experience has
shown that these do not always function out of the box and may not be fully compatible with Windows or with your computer's specific software. It is
recommended that you download the latest drivers from the Internet site of the manufacturer of the USB/serial adaptor. It has turned out that the drivers
delivered with the adaptor are not always up to date.
SSC 3
Q: Which COM port is normally used when I use an USB/serial adaptor.
A: This varies from PC to PC and it has to be found out in the operative system.
SSC 4
Q: Is OxyView required to change the sampling interval? If not, how is it done?
A: No. Communication and setting of sample intervals can all be done from a standard terminal program (like HyperTerminal). All this is explained in detail in
the Operating Manual.
SSC 5
Q: What is the minimum supply voltage for the sensors?
A: The minimum supply is 5V the maximum is 14V.
SSC 6
Q: What is the peek current consumption for the sensors?
A: Less than 100mA (for 0.5 second).
SSC 7
Q: Is it possible to drive the Rx, Tx signals from the Optode directly by the 0-5V without a transceiver?
A: No, you must use RS-232 levels.
SSC 8
Q: When logging the sensor in RS232 format what is the minimum of signal lines we have to connect?
A: The minimum is four; TX, RX, Positive Supply and GND. For more information refer the Operating Manual.
SSC 9
Q: If you switch ON / switch OFF the power supply between the data acquisition, do you have to keep a delay time before acquiring some data or after a
