PKP-2300-SI is a compact keypad based on CAN protocol. It comes equipped with six keys with interchangeable 15 mm inserts. The keypad is water and dust resistant, and can be installed both inside and outside the cockpit. RGB led lights and the ease with which icons can be switched in and out make it possible for the user to customize each key in a wide range of variations.


First introduction to PKP Series Keypad?

Here is a short product overview video.


CAN and RS485 Keypad Addresses

Assign any valid CAN and RS485 address to the keypad. Communicate on either BUS simultaneously.

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.

Online Set-up

An online set-up system makes it possible to select and design your own prototype, then order it directly on

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.
