THUMBDRIVE SERIAL DATA LOGGER

    

Model TD Serial Data Logger has extra special features which will help make your recording project a success.


  
    Binary and ASCII Recording
Allows you to record any kind of data using 8 bits, e.g graphics, escape codes, print emulations, plain text or even photos.
     
    Power Outage "Save"
Helps prevent a catastrophe if your data is lost because the outage leaves the log file unclosed. In that case you will be unable to open or use your log file because of a Windows file error. Power Outage Save is a special circuit that increases reliability.
     
    Auto File Close
Helps protect your valuable data by not leaving the log file open when not receiving data. There is no pushbutton required to close the file like other loggers.
 
  RS232, RS485, 5V TTL or 3.3V Data Interface
External RS485, RS422 and TTL level converters are not required. This makes the recorder installation neat and simple.
 

  Built In NUL Connector
Saves using external NUL Modem cables to reverse data pin wiring. This makes a quick and neat installation.
 

 
  Dual DB9 Connector
Male and Female connectors saves using external gender changers and also allows for inline recording.		 
   This serial RS-232 logger is also called a serial data recorder. It uses a USB/SD Card Reader or choice USB Flash Drive (also called Thumb Drive, Jump Drive, or Stick drive) to log
   continuously 24 hours a day, for weeks or months of recording. You will be able to easily and neatly connect this logger to your system as it accepts either male or female
   serial connector, and it also has a built in NUL Modem setting that saves you from adding a NUL Modem adapter to reverse the data Pins 2-3.
   
   As this recorder has two connectors, you can install it inline with equipment to record data in the background, e.g. record weigh scale data in the background
   going to a PC or printer. Only two wires are required for recording: 1. Data   and  2. Ground,  - so it is easy to install and does not interfere or compete with
   existing equipment RTS/CTS flow control handshaking. 
   
   - No software is required     - No licences are involved.
Use with:
  Machines    Measuring Instruments    Print Cables     Alarm Systems    Sensors     Modems    Embedded Microcomputers.
  Extra features help protect your precious data    
  If you are considering a logger/recorder device to backup measurement data for quality control records or to eliminate a printer then please consider this extra featured logger. It is meant to be used where stronger features are needed to support reliability. You will not want your logger project to fail, losing days, weeks or more of valuable information.

Thus, this design has added circuitry to help prevent such a loss. It mainly does this by closing the log file when no data is being received. So if the drive is accidently removed or if there is a power failure, or a device failure then the log file structure is already complete and won't be at risk. You will not have lost the data.

Heavy duty parts are used for increased reliability:
 

 

  

 

  
 
Large size power regulator LM7805 is rugged and has more capacity than required.
  
Transient Voltage Supressor Diode
adds serial line protection:
MFR Part# P6KE13CA
   
Settings are instantly readable.  Baud Rate and NUL Modem 
simulator are performed using both jumper straps and switches.
No software or configuation file is required.
