Recorder of data coming from RS232 port
RSD is a simple and modern electronic device used for recording any data coming from the RS 232 serial port. A correct recording of the frame in the device memory will be signalled by a flashing diode or setting the digital output for the time stipulated during configuration. Recorded data can be downloaded on the USB key, while the results may be displayed by means of a software, included into the recorder package.
The software allows to retrieve data from transmission frames saved in the memory (e.g. one frame of saved transmission contains 32 bytes. Equally essential data consumes only a few bytes of memory).
In the following mode, although the data flows regularly into the RS232 port, it will not be saved until the digital input activation takes place in the RSD. After setting the digital input in the high state, the RSD recorder will record the first received frame which shall meet the requirements set during configuration (e.g. requirements related to the length of the frame, to points marking the frame endings, etc.). It will then enter the standby mode to wait for another digital input activation.
In this mode, the RSD is able to send a frame, defined during settings, within a determined time interval.
In this mode, the RSD records a fact of some mass appearing on the weighbridge, if the mass value is higher than the threshold value defined during the configuration (e.g. 400 kg). The recorder records the maximum stable value of the mass, or the maximum unstable value of the mass, should there appear no stable value between entering and leaving the weighbridge. The recorder can also adjust a relay to a determined time period, should there appear any mass being greater than the threshold mass.
The computer software is delivered along with the recorder. The software allows to configure the recorder, read, export and display recorded data. It includes a graphics editor, by means of which the user can define the location of data in question on the incoming transmission frame. Owing to that, retrieving information, being a smaller part of a whole recorded transmission, can be easy.
By means of the RSD software, the user can:
To ensure proper operation of the software, it is required to have a PC computer with the Microsoft Windows 2000 operating system or its upgraded equivalent and one free USB port.
