PKP-3500-SI-MT is a new direction in CANbus keypads. This all new design comes equipped with thirteen push buttons with replaceable icon inserts, plus two rotary encoders that are also push enabled. Thanks to four additional analog and digital inputs, it is possible to connect 5V sensors directly to the CANbus network through the keypad. The compact layout and inclusion of the rotary encoders allows for significant dash space saving while expanding the functionality of the vehicle.



CAN Keypad Addresses

Assign any valid CAN address to the keypad.

J1939 Address Claim Transmission

Keypads no longer have to be pre-programmed to a specific address. This enables customers that work in applications in the field without access to a GUI to use any replacement keypad on-hand. The keypad can be configured to automatically announce its address and accept a new address assignment as appropriate.

Event Status Transmission

The keypad can send messages to the BUS indicating a button press or a button release event has occurred. This confirmation allows digital systems to have the same input acknowledgements as that of the latching position of a mechanical switch.

Periodic Status Transmission

The keypad sends a continuous broadcast of messages indicating the press or release status of each button at that instance. The frequency of these messages can be adjusted in a wide range.

Periodic Heartbeat

The keypad sends a continuous broadcast of  messages indicating it is functioning correctly. The frequency of  these messages can be adjusted in a wide range.
