1 1 What you get: 1. One or more demonstration boards 2. Board description (this document) 3. USB Stick or CD - with driver for elmos LIN converter - GUI - flash and auto-addressing software 2 What you need in addition 1. A elmos LIN converter V3 or above 2. A cable to connect elmos LIN converter and supply with the demonstrator board 3. An external Power supply for input voltage between 8V and 16V, capable of adequate current 3 Demonstrator System 3.1 Whole Demonstrator System Figure 1. Demonstration board A Demonstrator System consists of a PC / Laptop running the GUI, a elmos LIN converter V3 (LIN aster) and at least one ux Demo Board (LIN Slave). The GUI controls each of the four RGB LED independently as a virtual LIN Node. In fact a ux Demo Board has 1 physical NAD and 3 virtual NADs. The GUI support up to 26 NADs. If you connect more than 6 odules in a LIN row the LEDs above 26 can not be addressed and stay off. Two cable configurations are possible, which are described in the following 2 chapters. USB Port 12V Supply NAD 16 NAD 2 NAD 1 Figure 2. Whole demonstration system 1/6

2 3.2 Cable configuration 1 All modules are connected in a row like shown in Figure 2 & 3. In this configuration the supply voltage is passed trough to the following module. The master LIN signal is connected to CON1.2 which is connected to the LIN_ pin of the IC. The Signal passed though LIN_S to CON2.1. If is closed the LIN_S signal also passed though CON1.3. On the last module in chain has to be closed. PC USB elmos ULC12V USB Power Supply and LIN_ LIN converter V3 DC Socket 2.1mm inner contact 5.5mm outer contact 12V / 1A Up to 120 ma Up to 1 A 2xSB130 Up to 7 odules in a row 1 to 2 odules in a row: Supply of LIN converter is sufficient 3 and more odules in a row: especially at full brightness a external 12V supply is needed at DC Socket. The GUI support 6.5 (26 NADs) CON CON2 CON1 Figure 3. Demonstration system with cable configuration Cable configuration 2 All modules are directly connected to cable harness like shown in Figure 4. In this configuration is externally connected to CON1.1. is externally connected to CON1.4. The master LIN signal is connected to CON1.2 which is connected to the LIN_ pin of the IC. This IC delivers to CON1.3 if is closed. This LIN_S signal is delivered to the next LIN_ at CON1.3 and so on.

In worst case this is limited to 120 ma. In best case up to 4 modules can be supplied. In worst case 2 or 3 only. To ensure correct operation it is recommended to connect a external supply if more then 2 modules are connected. The DC Socket delivered by elmos have a inner contact of 2.1mm. This is connected through a Diode to. The outer contact of 5.5mm is connected to. The cables delivered by elmos have a current capability of maximal 1A. With the 2 diode implementation (see figure4) it is recommended to supply the DC-Socket with at least 12V. Otherwise the elmos LIN converter work in overload condition and no stable operation can be guaranteed. 2/6

3 4 GUI 4.1 Driver Installation To use the GUI the elmos elmos LIN converter has to be used. Windows 7 include a suitable FTDI Virtual CO Port driver. For older operating systems it might be necessary to install a driver from USB- Stick, CD or WEB. Afterwards it appears in the Windows Device anager. In the example in figure 5 it is CO3. This interface name is needed for the GUI. 4.2 Starting the GUI Figure 5. Find virtual CO Port At first the user has to write the correct string in the Config Field. If the elmos LIN converter use the CO Port 3 like described in chapter 4.1 the Config field has to contain ELCv3:Port=\\.\CO3. Casually the GUI store this information. Afterwards press the Connect Button. The Application starts to search connected NADs. All discovered NADs appears with a black check mark under the NAD number. Up to 26 NADs (LEDs) are supported. 2) Connect 1) Config 3) Detected NADs 1) LED Effects Figure 6. Starting of the GUI Figure 7. Use the GUI 4.3 Selecting LEDs for a Effect All discovered NADs are selected by default. Any of the NADs can be excluded by un-checking. The deselected Nodes hold the last defined state. 3/6

4 4.4 Selecting a Effect Three light effects are available. A static one with the marking.... Wave and Blinking. All with options. 4.5 PW frequency The modules could be changed in a area between 50 and 2kHz. At higher frequencies the intensity is limited due to significant slope loss. 5 Restart of auto-addressing If the modules are connected in a new sort order, or a demonstrator is expanded by additional modules the LED sort order could be wrong. In this case auto-addressing has to be restarted. For this purpose use lin-aademo.exe. The CO Port has to be released by disconnecting the GUI. Open a command box at the folder where lin-aademo.exe is available. Type the command LIN-AADemo.exe ELCv3:Port=\\.\CO step 4. If you use another CO port than CO3 please edit this command. Afterwards reconnect the GUI. 6 Firmware If the firmware has to be changed please follow these instructions. Disconnect the external supply and disconnect the GUI. In the following examples it is assumed you have 4 modules in a chain and the CO port is CO3. 1) Open a command box at the folder where lin-bmmflash.exe is available. 2) Type the command: lin-bmmflash.exe --low-speed --nad-range 1,4 autoaddr \\.\CO3 3) Type the command: lin-bmmflash.exe --low-speed --nad-range 1,4 --find-all \\.\CO3 Remark: In this example this command find 5 NADs the real existing 4 NADs and the broadcast NAD (0x7F). This low level flashing tool address real existing physical chips by LIN boot manager only. They are different from the virtual NADs used by the application. 4a) Bulk flashing (the following bulk flashing actions only works with more than 1 module) Type the command: LIN-BFlash.exe --nad-range 1,4 --find-all flash_bulk_erase --nad 0x7f flash_prog --no-erase --nad 0x7f firmware.a43 \\.\CO3 4b) Single module flashing: Type the command: lin-bmmflash.exe --low-speed --nad 3 flash_prog firmware.a43 \\.\CO3 4/6
