  • Page 3: About

    Introduction The CAN-port unit is designed as an interface between a CAN network and a Newtons4th PPA series Power Analyzer. The unit receives commands from the CAN network or via serial (RS232) and then processes these commands and controls and instructs the PPA;...

  • Page 5: Quick Start

    To load new firmware into the CAN-port unit, ensure it is powered off. Connect the CAN terminal to a PC using a CAN converter. To place the CAN-port unit into Boot Mode, hold the boot switch on and then power on the unit. The light on the CAN-port unit should be flashing orange, indicating it has successfully entered boot mode.

  • Page 6: Connecting To Ppa Datalogger

    Ensure the CAN-port unit is powered on; the status light should be blinking green. Once the CAN-port unit is on, connect an RS232 cable to the serial port and connect it to your PC. Open the PPA Datalogger software and navigate to the PCAN menu.

  • Page 8: Adjusting The Can-Port's Settings Using Ppa Datalogger

    The CAN Message Settings allow you to edit how the CAN-port unit interacts with the rest of the CAN network. CAN Read ID is the CAN message ID (in hex) that the CAN-port unit will accept CAN messages from. CAN Reply ID is the CAN message ID (in hex) that the CAN-port unit will send its CAN messages to.
  • Page 9 Reply with old data if no new data is available? ensures the CAN-port unit sends a reply when multilog data is requested, even if no new data is available. The previous set of data is sent in case a new set of data is not available.

  • Page 11: Setting Up Multilogs For The Can-Port In Ppa Datalogger

    Using PPA Datalogger you can select up to 60 Multilog parameters that can be set into the CAN-port unit which it will, when powered on, send the corresponding commands to the PPA to set it up to log those parameters.
  • Page 12 The selected values will now appear in the list on the PCAN Setup page; to change the selected multilog parameters, pres Select Multilogs again and change your selection. The first value is Data Count, because we have “Send the first reply in a multilog response as the data count?”...
  • Page 13 Selecting Custom allows the ID to be changed using the “Edit Selected” button. To use this button, select a multilog by clicking it (other than Data Count) and press the Edit Selected Button. Editting a multilog allows you to change the format type, start location in the message, the length of the message this value will use up and a scale factor and offset.

    PPA and ensure the PPA is turned on and its interface is set to RS232 (and with the correct baud rate) in the REMOTE menu. From then onwards, each time you turn the CAN-port unit on, it will then set up the PPA as per the settings from PPA Datalogger.

  • Page 17: Communications Usage

    Commands can be sent to the CAN-port unit either by sending a CAN message with the CAN Message’s ID set to the ID that the CAN-port unit is set to read over the CAN network, or by connecting to the CAN-port unit with a serial (RS232) connection and using Newtons4th’s CommView2 program.

    Requesting Multilog Data To request Multilog data from the PPA via the CAN-port, simply send a direct command to the PPA using the “MULTIL?;”, “MULTI#?;” or “MULTIL,lines?;” query over CAN, as described in your PPA’s Comms Manual. The “MULTI#?;” command will be sent for you automatically if you have set the CAN-port to repeatedly request data from the PPA, and on power up if POWML is set (either via command or by using PPA Datalogger’s “Request Multilog Data...
