That device is going to require some work to understand it behaviors.

-- first step -- wire it as the only device on one of the dash's CAN buses. Be sure to observe CAN termination requirements. This will allow you to experiment with the device. Not sure if this is fixed yet (to work with the color dashes), but consider using the CAN Inspector tool (from the MoTeC utilities download) to see what if any messages it is sending by default. Your document should help you decode those.

-- note the default CAN rate is 125 kbit/sec. But you can send a message to change it's speed -- will that be preserved across power off? Need to investigate! Do you need to share this device on a CAN bus with other devices? If so, then you will likely need to change it's default CAN rate.

-- write CAN templates to allow you to transmit and receive messages from this device.

I you are not comfortable with the steps above, I suggest you contact a professional (such as your MoTeC dealer) to help you integrate this device into your system.

I have Connected the Device by using CAN-H and CAN-L,now the power is supplied to the device,now i need to enable the keypad,is it possible to enable without the help of a PDM,if yes can you tell me how can i do it..

If you aren't getting messages from the device, did you try sending the CAN Open command to start it (ie, send 0x01 0x15 to CAN id 0?)

CAN Open requires a number of different messages to configure and enable the device. If you want to change it from the default settings you could possibly use the Keypad configuration utility in PDM Manager (you don't need a PDM to do this). However, I don't know whether it will set everything for this particular device correctly.

The other option is to look up the CANOpen specification and workout what messages need to be sent to the Rotary Switch to configure it. There will be around 15-20 separate messages that need to be sent.
