 IC - LONWorks (62)  V. 2.5

30.9.20

3.2.10 -Config Mode

If the pin has the level GND, then the IC starts in the configuration mode.

3.2.11

DbgTX, DbgRx

They are transmission line and receive line as well of the IC’s Debug-interface. For the function

 

description of the Debug-interface see chapter 6.

3.2.12 TE

The transmit enable signal allows the connection of RS485 drivers to the IC’s serial interface. 
The signal is set to 5V whenever the IC sends via the line TX.

3.2.13 TX, RX

Transmission and receive line of the serial interface. This interface is programmable in accor-
dance with the description in chapter 4 on page 22.
