How to log RS232 port activity?
The basic principles of RS232
RS-232 is a wired duplex interface. The data transfer method is similar to the asynchronous serial UART interface.
The information is transmitted via wires with a binary signal with two voltage levels (code NRZ). The logical "0" corresponds to the positive voltage (from +5 to +15 V for the transmitter), and the logical "1" is negative (-5 to -15 V for the transmitter). For electrical matching of RS-232 lines and standard UART digital logic, a large range of driver chips is available, for example, MAX232.
In addition to the input and output lines, RS-232 regulated a number of optional auxiliary lines for hardware flow control and special functions.
BRIEF DESCRIPTION:
Serial Port Logger inputs RS232 information straightforwardly into document, Excel, Access, or any Windows application. Serial Data Logger gives ongoing information gathering from any serial gadget or instrument. Send and get RS232 information over a RS232 port or RS485 port with equipment converter.
WHAT PROBLEMS CAN BE SOLVED WITH ADVANCED SERIAL DATA LOGGER?
RS232 logger catches serial information, custom tailors it to your necessities, at that point remove bits of information from information parcels and exchanges the information to any Windows or database - either by sending keystrokes to the application's window, by going the information through a local interface (OPC, DDE ODBC, OLE) or send information to Internet. It permits to execute basic and complex automatization errands in the blink of an eye without unique programming.
