Fig. 4: A919 3-button board
The 3-button board has two K-bus interfaces 1, CON400 & CON401. "KBUS IN" connects the board to the
USB-to-KBUS coupler and transmits one make contact and the LED per button. A jumper must be set on
"KBUS OUT" as the terminating resistor. The external connection strips 2, CON600 & CON601, are used to
supply power to the indicator lamps.
The second contact of each push-button is wired to the 19-pin round connector via connection strip 3,
CON603.
Three digital inputs are available on connection strip 4, CON602, which can be assigned ex factory.
