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

|Extra features help protect your precious data
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.
Large size power regulator LM7805 is rugged and has more capacity than required.
