¶ Converting from Blink protocol
Our keypads are pre-programmed to a specific communication layout. If you have a universal Blink keypad, you can configure it to a “CANTCU-keypad” by sending it specific configuration commands through CAN. Note that you need basic knowledge and understanding of CAN-bus in general, and a suitable CAN-tool/device/analyzer that is able to send out frames on the CAN-bus.
- Disconnect ALL other devices except the keypad from the CAN-bus
- Make sure that the CAN-tool/device/analyzer you are using is configured to the same bitrate as the keypad. If you're unsure about the keypad bitrate you will have to cycle through different bitrates until you find the correct one.
- Send the necessary configuration messages to the keypad, table below.
