CleverTerm

The clever terminal program for serial port and field-bus communication.

• Build your own sending dialogs and create customized user interfaces
• Simulate field-bus telegrams
• Play Modbus ASCII/RTU master with predefined Modbus function dialogs

CleverTerm is a program to communicate with devices via RS232, RS422 or RS485 by using a serial port. It is especially developed for testing field-bus applications in the automation technology. CleverTerm is free and available for Windows and Linux.

Special features :

EXPANDABLE Build your own dialogs : A unique feature of the CleverTerm program is the option to extend its functionality by own sending dialogs written in Lua. These range from simple inputs like to generate telegrams with individual checksums to a complete simulation of Modbus master requests.

DUAL VIEW Hexdata and telegram view : Simultaneous display of the raw data as hex dump and in a line by line telegram arrangement gives you a best view over your transmission. Different colors let you distinguish between the data direction.

MODBUS SUPPORT Simulate a Modbus Master : Instead of building a valid Modbus byte sequence by hand (including the right checksum), you just select the function number in the Modbus dialog and input the device address and function parameter.

CHRONOMETER An integrated stopwatch : let you stop the time for every sent single telegram and measure the transmission time of a huge data block or file transfer for performance tests.

ERROR INDICATOR Don't miss occurring errors : CleverTerm shows you the number of the frame and parity errors as well as the count of UART buffer overruns and occuring breaks.

PORT DETECTOR Select the device behind a port : Don't bother with not meaningful port numbers any more. CleverTerm shows you the device assigned to the port with product name, vendor information and device state (used or free). Further you can tag a device with your own name alias.

Also good to know :

PERFORMANCE CleverTerm provides a GUI independent and non-blocking device access. The transmission speed only relies on the OS and the device itself and guarantees maximum performance.

HARDWARE SUPPORT CleverTerm works with all kind of serial ports and USB to RS232/RS485 converters supported by your OS. Depending on the device it provides baud rates from 1 to 1MBaud and static mark and space parities.

COMFORTABLE INPUT let you enter und edit sending byte sequences as best as it fits your intention. CleverTerm offers data input in ASCII, HEX or mixed. A history function makes it easy to edit and/or repeat a former byte sentence.
