1. How to connect Deutsch 4 pin:

Each end of the CAN bus is terminated with 120Ωresistors in compliance with the standard to

minimize signal reflections on the bus. You may need to place a 120Ω resistor between CAN-L and

CAN-H.

3. Message header description

The 29-bit CAN identifier used in J1939 is structured in the following way.

Priority

Reserved

Data Page

PDU Format

PDU Specific

Source Address

3 bits

1 bit

8 bits

The proprietary format used by PK and PKP keypads is defined as follows:

Priority = 6.

Reserved = 0.

Data page = 0.

PDU Format = EFh (the message is addressable).

PDU Specific = Destination Address.

Parameter Group Number (PGN) = 61184 (EF00h).

An example of CAN identifier of messages sent to the keypad is 18EF2100h where:

21h is the destination address (keypad)

00h is the source address.

An example of CAN identifier of messages sent by the keypad is 18EFFF21h where:

FFh refers to broadcast messages (no specific destination address)

21h is the source address (keypad).

4. General Data Format

The proprietary protocol has defined a general format for the data fields in the PGN 61184. The format

consists of:

1 header field (2 bytes)

1 command byte

8 bytes (the remaining field) are defined specifically for each command.

The data length is 8 bytes, unused bits and bytes are set to all 1’s (0xFF).

14. Periodic state transmission (71h)

This message enables or disables the periodic transmission of the Key state.

When enabled, one contact state message is periodically sent for each button of the keypad. For

some keypad models there could be additional messages (e.g. the PKP2400 has 8 button but 11

messages are sent).

The period is set to 100ms as default value but can be changed by command 77h.
