3.4.1 Standard Configuration
The standard J1939 CCM12 is an arbitrary address capable device, supporting three proprietary transmit PGNs
and two proprietary receive PGNs. The transmit PGN contains control data from the OCU, and the receive PGN
contains feedback information to be sent to the OCU for display.
Table 11: PGN summary
PGN FORMAT TX/RX CONTENT
65280 PDU2 Tx Digital inputs (OCU pushbuttons, switches)
65281 PDU2 Tx Proportional inputs 1 to 6 (OCU paddles/joysticks)
65282 PDU2 Tx Proportional inputs 7 to 8 + alternate digital inputs
65288 PDU2 Rx Feedback bits 1-64
65289 PDU2 Rx Feedback bits 65-128
The PGN standard definition is described in the following documents:
[3] Cattron #9S02-8019-
A002, “Standard J1939 Protocol Specification”
[4] Cattron #9S02-8019-
A100, “Standard J1939 Protocol Specification for Pushbutton OCUs”
[5] Cattron #9S02-8019-
A200, “Standard J1939 Protocol Specification for LRC-M1 OCU; N-A Standard
Configurati
on”
The transmit PGN mapping depends on the RF Telegram Format. Reference [3] is the general specification,
applicable to Telegram Formats 0F, 1F, 2F, 3F and 4F. Reference [4] is the application of [3] to Cattron
pushbutton OCUs (Excalibur and MKU), which employ Telegram Format 0F. Similarly, reference [5] is the
application of [3] to the N-A standard LRC-M1 configuration.
3.4.2 Custom Configurations
Custom definitions can also be implemented by Cattron based on customer requirements.
3.4.3 Rotary Switches
The rotary switches are not used in J1939 mode.
3.4.4 LEDs
The MCU CAN1 and CAN2 LEDs are bicolor (Green and Red). CAN1 is associated with the master controller and
CAN2 with the slave controller.
The Red component indicates the status of the CAN physical layer (as defined in the CiA DR303-3
recommendation for the ERROR LED). The Green component indicates the state of the J1939 address claiming
process.
In the case of conflict between turning the LED Green or Red, Red has priority.
