Description

The Baby-LIN-3-RC is part of the third generation of Baby-LINs introducing new and more powerful features.

All devices are powered by a 480MHz Cortex M7 core increasing the possible speed by 60% in comparison to the previous generation, allowing faster SDF execution and leaving reserves for new software features. To emphasize this performance leap the devices are also now equipped with a native high-speed (480MBit/s) USB connection and a USB-C connector, making it more convenient and reliable to use. We also further improve the usability of our devices by offering a male SUB-D9 connector for all bus signals, allowing the user to secure the connector to the device and giving more flexibility for upgrades from one device to another. Of course, we are upholding our compatibility guidelines for previous generations so all devices have still the established three pin plug for the LIN bus.

The power for the Baby-LIN-3-RC can be supplied either from the USB or the LIN-Bus side. If the device is powered by the LIN-Bus it can be operated without the need for a PC. All communication interfaces (LIN-Bus and USB) are galvanic isolated, eliminating interference between the PC and the board electronics.

The Baby-LIN-3-RC allows controlling LIN-Bus equipped devices by using a standard personal computer. After installation of the supplied LINWorks software, you can connect the Baby-LIN-3-RC to a free USB port, and access the LIN-Bus devices via LINWorks or custom programs by using the Baby-LIN-DLL.

Two red/green colored LEDs on the side show device information but can also be utilized by the user for other needs.

The Baby-LIN-3-RC has an integrated membrane keyboard with 9 keys and a 1,54" ISP color display with 240x240 pixels. Thus, it is usable as an autonomous remote control for the bus. Each of the six function button can be assigned to any commands, the dedicated bigger Start and Stop key allow for quick execution of macros or other functions. Using two keys as SHIFT-keys extends the usable number of six keys up to twelve. The ninth buttons is dedicated to enter or leave the menu of the device to show information, edit features of the device and more.

All this is shown on the new display. An easy to use GUI editor will be implemented in the LINWorks so users can show elements like bus signals or macro results directly on the screen.

The device firmware is field updateable, so the changes of bus specification or upcoming new system features can be adapted easy.

The Baby-LIN-3-RC supports SDF-V3 and is prepared for SDF-V4.

Operation mode

Any situation that requires communication with a LIN-Bus device is a potential field of application for a Baby-LIN-3-RC . It is a versatile tool that can be used in research laboratories, test departments and production (EOL applications).

• Monitor and log all frames on the bus without the need for a SDF. If a SDF is available signal values can also be monitored.
• Control the bus via the LINWorks software or customer specific applications by using the Baby-LIN-DLL.
• Program and store free programmable command sequences in the Baby-LIN-3-RC to run it as a stand-alone device without the need for a PC. Thus you can run a bus driven ECU in a durability test or EOL applications without any PC connected.

LIN-Bus properties

The used LIN driver supports bus voltages of 8-26 VDC and can be used up to 115200 Baud. That way even nodes that operate outside the standard limits of the LIN specifications can be controlled with the Baby-LIN-3-RC .

Supported LIN-versions are V.1.2 to V.2.2. The pull-up resistor of the LINBus driver is internally switched to 1 kOhm, if the master node is emulated.

LINWorks suite

The purchase of a Baby-LIN-3-RC includes the license to download the LINWorks suite. This suite is a collection of PC software that supports you during the whole workflow. The LDFEdit allows the inspection, creation and edit of a LDFile (LIN Description File).

The SessionConf allows the inspection, creation and edit of a SDFile (Session Description File) and features a file import for LDFiles (for LINBus simulation). It defines everything needed for a complete simulation of each available bus, e.g. which nodes on each bus are available and which nodes should be simulated by the Baby-LIN-3-RC . Moreover it allows defining an application logic. This programming ability is available for each device out of the box.

The SimpleMenu is used to establish a connection to the Baby-LIN-3-RC and upload SDFiles, change the device target configuration, control the bus and monitor the frames and signals on the bus. Even without a LDFile or SDFile the bus can be monitored and the frames can be logged.

The Baby-LIN-DLL allows customers to create their own application and use all features of the Baby-LIN-3-RC like controlling and monitoring the LIN- and CAN-Bus interfaces. The Baby-LIN-DLL is a native C/C++ DLL. It is available for Windows, Linux and RaspberryPi. Wrapper for NET, Python, VB6 and LabView are available. Of course we provide examples for all supported languages.

The LogViewer can show and convert the log files of the Baby-LIN-3-RC as well as the SimpleMenu.

The LINWorks software runs on 32 and 64 bit Windows 10 or higher versions.
