COC board pressed onto the Raspberry Pi header, annotated "no gap" Make sure there is no gap left. Press the two PCB so you can hear/feel a litlle “click” …

RPi - 512MB special note:

Section titled “RPi - 512MB special note:”

At the 512MB version board of RPi the connector handles have become very big. The hole provided at the ROT is 2.9mm only!! Therefor the handle needs to be removed: Removing the connector handle: widen it first, then pull it off UPDATE: The newest RPi charge even uses a 3mm thick connector. This is about 0.1mm too big for the slot at ROT. In case you got one of those RPis you must rasp away some micrometers of ROTs slot to make it fit.

System

Section titled “System”

The i2c-bus number used below might differ depending on yr RPi version or kernel

TPUART - EIB/KNX bus access

Section titled “TPUART - EIB/KNX bus access”

You need to free-up the serial line used by ROT remove any references to ttyAMA0 in:

  • /etc/inittab - comment or delete: T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
  • /boot/cmdline.txt - and reboot!

RPI3 + JESSIE:

add to: /boot/config.txt dtoverlay=pi3-miniuart-bt

change: /boot/cmdline.txt dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

commands to issue: sudo systemctl stop serial-getty@ttyAMA0.service sudo systemctl disable serial-getty@ttyAMA0.service sudo reboot

then:

sudo -u pi eibd -i -D -T -S -e 1.1.251 tpuarts:/dev/ttyAMA0

(For Banana Pi the device is called: /dev/ttyS2)

ETS configuration to access ROT - use SCAN-button to find IP-address: ETS connection manager with a KNXnet/IP connection configured for the ROT
