TPUART board
TPUART board
The Siemens TP-UART-IC (I call it TPUART, for short) can be used to build a versatile interface for connecting a PC to a KNX TP1 (EIB TP) network. Its datasheet is available at the Siemens Website (Technical documentation / Transceivers / TPUART).
At the institute, we use an interface board with the following schematic
(built and assembled by institute members):
This board was used to develop the TPUART driver (deprecated) and the TPUART user mode backend of eibd.
As some people have asked how to get a TPUART interface board:
- Build the board shown above yourself: This zip file contains the schematic, the PCB layout (in PDF and EAGLE format), and the parts list. We order our boards from prototype/small series PCB manufacturing services such as PCB-Pool (www.pcbpool.com). TPUART ICs are available from Opternus Components (www.opternus.com).
- For those who want pre-assembled boards: Fritz Praus (currently technician at the institute) is selling complete boards as shown above. If you are interested, please contact him directly: fritz@praus.at.
- Since recently, Siemens also offers an interface board for sale: Siemens BTM PCB. To connect it to a PC, a level converter is required. It worked with eibd when I tested it with the Siemens 5WG1 146-2AB11 application module.
In order to justify continuing development, it is helpful to have an idea of how many people are using this software.
To contribute, please send a short mail to bcusdk@auto.tuwien.ac.at whether you find this software useful.
