Docklight is a testing, analysis and simulation tool for serial communication protocols. It allows you to monitor the communication between two serial devices or to test the serial communication of a single device. Docklight is easy to use and runs on almost any standard PC using Windows 10, Windows 8, Windows 7, Windows Vista or Windows XP operating system.
Docklight can send out user-defined sequences according to the protocol used and it can react to incoming sequences. This makes it possible to simulate the behaviour of a serial communication device, which is particularly useful for generating test conditions that are hard to reproduce with the original device (e.g. problem conditions).
Docklight will work with the COM communication ports provided by your operating system. Physically, these ports will be RS232 SUB D9 interfaces in many cases. However, it is also possible to use Docklight for other communication standards such as RS485 and RS422, which have a different electrical design to RS232 but follow the RS232 communication mechanism.
Docklight has also been successfully tested with many popular USB-to-RS232 converters, virtual null modem software drivers, and many other Embedded Development tools that appear as a virtual COM port in Windows.
