RS232 Analyzer
Introduction
Designing / debugging a communication project can be very stressful and
time-consuming. Many software / site engineers get stuck on the protocol
before they can actually control a serial device (RS232, RS485, RS422,
TTL, Modbus, PLC, SCADA, etc.).
Serial
protocol can be very complicated, it requires that you not only
understand the context of the protocol and the data format (ASCII,
Hexadecimal, Binary, etc.), but you must also know how to do the
Checksum Calculation (Checksum is the additional bytes added at the end
of the data string to check the data integrity. Checksum Calculation
varies from the simplest xOR to sophisticated CRC). Timing is another
critical issue as some protocols require acknowledgement/response within
milliseconds.
Designed to tackle all these problems,
232Analyzer (an advanced RS232 Protocol Analyzer)
allows you to play with the protocol with all available data formats
(ASCII, Hexadecimal, Decimal, Octal and Binary). It also helps you to
verify the problem by monitoring the communications between two serial
devices. As an example, 232Analyzer allows you to control,
monitor (spy) serial port devices right from your PC.
With 232Analyzer, even non-technical people can understand and play with
the protocol within minutes.
232Analyzer comes with two communication
modes: Debugging/Simulating and Monitoring. Debugging/Simulating mode
(in which it functions as a Terminal, Debugger / Simulator)
provides an easy way to test your command codes, from which you can
send/receive commands/signals to/from external serial devices.
Monitoring mode (both Half-Duplex and Full-Duplex are supported) allows
you to monitor (spy)
communications between any other two serial devices. Timestamps in
millisecond are provided in this mode. All data communications are
recorded and can be saved as .txt, .rtf or .doc files.
Besides all formats of data inputs:
Hexadecimal, Decimal, Octal, Binary and ASCII, 232Analyzer also allows
you to change / monitor RS-232's line states: RTS, DTR, CTS, DSR, DCD,
and RI.
232Analyzer comes with
an advanced Checksum Calculator, which allows you to do the following
calculations:
- Bit wise Logic Calculation:
AND, OR, XOR, NOT, Reverse Bit Order
- Math Calculation: +, -, x, \,
Mod
- CRC-16 (for Modbus)
calculation
Other advanced features like
Programmable Buttons, Auto-Response, and Macros are also
included in the software.
