The 4-push button board A920 has two K-bus interfaces CON400 and CON 401 (Fig. 4, No. 1), which are
assigned ex factory. "KBUS IN" connects the board to the USB-to-KBUS coupler and transmits one normally
open contact and the LED for each push button. A jumper must be set as a terminating resistor on "KBUS
OUT".
The external connection strips CON600 and CON601 (No. 2) are used to supply power to the indicator
lamps. You can also use the connection strips on connection strip 4.
The bridges between the PCBs are assigned ex factory, you have to take care of the power supply. You can
additionally use one of the two normally open contacts per push button via a CON603 connection strip (No.
3).
Four digital inputs are available at the connection strip CON604 (No. 4), which are transmitted via the K-bus.
