DONGKER Bus Module Transceiver
WHY CHOOSE DONGKER Bus Module Transceiver？
- It is a TTL_UART to LIN bus module.The module uses TJA1020 chip.It is mainly used for communication monitoring and maintenance of LIN bus equipment.
- The measured baud rate of the module can reach 57600bps,and the recommended maximum operating frequency is less than 20Kbps.
- This module is just a level conversion module and does not participate in conversion analysis such as software protocols.
- When the module is connected to the computer's COM port,the computer can receive data,but it cannot communicate with your slave device as a host.The computer's com port cannot generate the 13-bit start bit in the LIN protocol,but it can be connected to a development board such as a microcontroller.1>.Product Name:TTL_UART to LIN Bus Module 2>.Product Chip:TJA1020 3>.Working Voltage:DC 12V 4>.Work Temperature:-25?~85? 5>.Work Humidity:5%~95%RH 6>.Size:43*22.5*14.5mm

While this module does work as expected, the connections labeled "Tx" and "Rx" are actually connected to the opposite pins on the 1020 transceiver ID. When connecting this to a microcontroller, connect your microcontroller serial port TxD to the "RX" connection, and the RxD to the "TX" connection.

Arrivata con IC aggiornato al 1021T e non come pubblicizzato il 1020. MeglioScheda relativamente cara.

Ich benutze dieses Modul, um am Webasto W-Bus zu lauschen. Zusammen mit einem einfachen UART-TTL USB adapter kann man schön alles fragen und verfolgen, was da auf dem Bus so zu fragen und zu verfolgen ist. Dabei kommt man auch an interessante Informationen, die einem kein normales Webasto Bediengerät anzeigt, wie zum Beispiel die aktuelle Heizleistung. Darüber kann man dann recht genau den aktuellen Brennstoffverbrauch berechnen. Endlich weiß ich, wieviel Diesel meine Heizung verbrät.Auf dem Oszi-Bild sieht man schön, wie das LIN-Signal (gelb) schon recht verschliffen in ein sehr sauberes UART-TTL Signal (blau) gewandelt wird.
