PKP-2300-SI-FR is a compact keypad based on CAN protocol. It comes equipped with six keys. The keypad is water and dust resistant, and can be installed both inside and outside the cockpit. The PKP-SI-FR (full rubber) Series has a solid rubber key face instead of a removable insert. It is a production based unit where the icon design remains the same, saving installation time not having to populate inserts. The PKP-SI-FR Series also allows for a larger surface area for the icon from 14mm dia to an increased 18mm dia.



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.

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.
