Docklight - Test & Simulate Serial Protocols (RS232, TCP...)

Simulating a RS232/UART device protocol, based on RS232 logging data (Reverse Engineering)
You can use Docklight log file data to create a basic simulator for an existing device. This can be done manually, or using a small helper tool available from our FAQ.

Testing an IoT I/O application with simple text-based control commands
With Docklight Scripting you can connect to IoT devices via TCP or UDP and perform manual tests, or write small automated testing procedures. Docklight Scripting can simulate data telegrams from an IoT device to a server, e.g. temperature readings, or be at the receiving end for such data.

Logging and processing RS485 2-wire-bus (half duplex) data
A plain RS485 bus log does not reveal which node sent the data. By defining the basic application protocol structure via two data sequence triggers ("Receive Sequence"), you can use Docklight to separate the answers of the bus members, here a motor and a PLC. Docklight hardware accessories like Docklight Tap 485 provide accurate monitoring data without interfering with the original communication.

Network gateway between a TCP client and a UDP peer
Docklight Scripting takes over two roles here - a TCP Server which allows the client to connect on TCP port 9000. And a UDP peer that communicates with a remote network address. The data transmitted back and forth is evaluated on the fly and chosen network events are logged to a custom text file.

Testing a USB HID protocol implementation
In an Embedded Device project with a custom USB HID protocol implementation, Docklight Scripting was used for two tasks:
1) Test the protocol implementation on the USB HID side, here a CAN bus interface functionality based on the SLCAN ASCII protocol.
2) HID to UDP/Ethernet bridge that allows to access the new device via standard UDP/Ethernet packets.

“Docklight has been a huge productivity tool in testing our reader software. It has allowed us to automate some difficult sequences, including some encryption sequences that involve cipher block chaining. Testing these sequences by writing tools from scratch would have taken an inordinate amount of time.
Docklight has allowed us to stay on track with our schedules. In addition, Docklight support has far exceeded any support I have received in many years. Oliver was particularly helpful in guiding and directing me and in working with me to solve some challenging problems. I felt as if I had a true partner and mentor.”

“ I am a happy Docklight owner. We use your software to test the serial ports on products that we manufacture. We often suggest to installers in the field to use the Docklight program to help diagnose problems they have. ”

Russound/Docklight Demo Project and Application Note

“ I thank you for your assistance and flexibility. We currently have a single Docklight license we have been using for a while (not in its full capability). But recently my tester … has created a nice script which will assist on his current project over the next few years. "

“ Als langjähriger Nutzer von Docklight möchte ich mich ganz herzlich für die stetige Wartung und Verbesserung Ihrer tollen Software bedanken. Dass man als Kunde diesen Service dann immer noch kostenlos bekommt, ist alles andere als selbstverständlich.
Ich nutze Docklight nicht ständig, aber immer wenn es zu Problemen mit der Kommunikation zwischen Computer und diversen Messgeräten kommt, hilft mir das Programm, diese zu lösen.”
