2. Setting up LITOS' hardware
Electrical components on the LITOS PCB
- In rare cases the display might not be already attached to PCB. In this event, please plug the display into the headers in the middle of the PCB.
- Connect LITOS to a computer with a micro USB cable. Then run the “litos_flash.exe” script and follow the on-screen instructions to flash LITOS. After the flashing process, please remove the USB cable.
- Connect the flat ribbon cable (16 pins) to LITOS. On the LED matrix there are two connectors for the flat ribbon cable. Please connect the cable to the input connector. It is located on the left side if the arrows on the back of the LED matrix point to the right and/or to the top.
- Next, connect the power cable to the matrix and the PCB (cable with red / black wire). In order to insert it into the screw terminal on the PCB, we recommend that you cut off the metal fork at the end of the cable and then strip the two wires a bit. Alternative you can also bend the metal fork teeth. The red cable end belongs to “+Mat“, whereas the black cable end is inserted into the side labelled with “-Mat” on the screw terminal.
- Start LITOS by connecting it with the wall power adapter.
- Connect your notebook to the access point LITOS has created (like if you would connect to a W-Lan network). The name of the access point (SSID) is displayed on LITO’s screen (default name is “LITOS”). Open next a web browser (Firefox, Google Chrome, Safari, Edge) and enter 192.168.1.1 in the address bar to access the user interface. If you have problems establishing a connection to LITOS’s web interface, please restart LITOS by pressing the RST (Reset) button on the PCB.
- LITOS can be customized on the setting page in the user interface.
Due to the high humidity, we recommend placing only the LED matrix with the microplates inside the incubator. LITOS’s PCB with the wall power adapter should be placed outside.
