1.6. Toggling Polling- / Scan-Mode
There are two ways to toggle between polling and scan mode.
•
By soldering a 0
Ω
resistor in B1 (see: 1.3. Technical data ) scan mode is permanently activated.
•
To temporarily activate scan mode, you can tie input MOD1 to potential GND (X2 / Pin 3).
The following table shows the possible configurations.
