Overview

What is Docklight?

Docklight : Monitor the communication between serial devices, test the connection and analyze ports, or simulate activity by sending data sequences

In depth

A closer look at Docklight

Docklight is a comprehensive simulation and testing tool for serial communication devices. The application supports RS232, RS485/422 and other standards, Bluetooth and Arduino ports, allowing you to monitor the communication between two serial devices.

Neatly organized interface

Providing a well-organized interface, the application comes in handy to software testers who require certain test conditions, since it can simulate the behavior of a communication port by sending user-defined data sequences and automatically respond to received ones with user-defined answers.Both sent and received serial data is displayed within the main window, in ASCII, HEX, decimal and binary form. Docklight features communication logging, enabling you to store information in plain text or HTML format.

Can toggle between high data throughput and high monitor accuracy

Docklight provides you with the possibility to choose between high data throughput and high monitoring accuracy. The latter option uses computer resources and might freeze the computer if the traffic amount is elevated.In order to identify a certain data sequence in the communication window, you can use the search tool. Therefore, problem conditions can be easily detected and the application enables you to take snapshots of the communication data or send a diagnostics command in order to find the source of the error message.Routing serial data traffic, configurable connection parameters (baud rate, parity, data and stop bits), flow control (manual reset of RTS / DTS), communication filters (it can display data transferred using a single channel or both) are other advantages that this application comes with.

Customize the communication window

The communication window appearance is fully customizable, enabling you to set different colors for sets of data, in order to distinguish them easier.Docklight can be used in different fields, such as equipment manufacturing or communications. It has the capacity to automate data sequences, perform serial port tests and diagnose problems.
