Serial Data Logger Specifications

All of the following specifications have been tested in the field.

Specifications are conservative and in most cases the Serial Data Logger will perform better than specified.

Note: Due to constant product development, specifications are subject to change.

Functional Description:

This Data Logger will capture and store all incoming serial data. All values from 00h to FFh are captured.

Data can then be downloaded using a standard terminal emulation package such as Hyperterm. Special download software is not required.

The Datalogger has two modes of operation, controlled by a voltage level on pin 1 of the DB9 connector:

  • Capture mode:
    • Pin 1 high (open): All incoming data is captured to memory
  • Download/Command mode:
    • Pin 1 low (shorted to ground): Datalogger will wait for a command
    • Download will commence when the 'download' command is received
    • Memory can be cleared with a separate 'clear' command

A download cable is supplied, which will enable command mode when connected to the Datalogger.
