Communication timeout
This function is available in the J1939 version of the keypad only.
The keypad offers the functionality to signalize a communication timeout. If no “Prop A”-
message is received for a specified time the halo LEDs of the keypad will start to flash white.
Communication can be started again by sending “Prop A”-messages. Once in communication
timeout mode the LED settings will revert back to the off state. Other values that were stored
in volatile memory will not be lost. The LEDs will just be turned off.
The timer for when the timeout mode will be entered can be configured in the corresponding
lost communication timeout object (0xA3). The default value of this object are 2 seconds.
Please refer to the K-Matrix to see which values can be chosen.
