2.1 Connecting to the CAN Bus The PEAK-MiniDiag NMEA 2000 has a 9-pin D-Sub socket on the back of the device for the connection to the NMEA 2000 bus as well as for the primary power supply. Both are realized via the supplied NMEA 2000 connection cable.
Note: Make sure that the polarity is correct (+/-). 4. Put back the cover. 5. Tighten the two Phillips screws. The PEAK-MiniDiag NMEA 2000 is now ready for operation. If the PEAK-MiniDiag NMEA 2000 is connected to the NMEA 2000 bus supply, the batteries 2 Commissioning PEAK-MiniDiag NMEA 2000 User Manual 1.0.1...
However, in case of a poor bus supply, the device automatically switches to the battery supply. 2.3 Turning on/off The PEAK-MiniDiag NMEA 2000 is turned on and off by pressing the Enter key Press the Enter key once to turn on the PEAK-MiniDiag NMEA 2000.
2.5 Operation The PEAK-MiniDiag NMEA 2000 is operated via four keys. Navigation and selection are done using the arrow keys . The gear wheel key opens the options of the currently displayed function. The Enter key executes actions or confirms changed settings.
3 Device Functions This chapter covers the device functions of the PEAK-MiniDiag NMEA 2000. The following subchapters describe the 12 functions. The navigation is carried out using the arrow keys . In the following table, all functions are listed in order to the right...
The following options are available via the gear wheel key Shutdown time A time from 2 to 30 minutes can be set after which the PEAK-MiniDiag NMEA 2000 shuts down. The time-controlled turn off is deactivated with the setting never. Supply type...

Call bootloader The bootloader can be activated in order to perform a firmware update with the help of the PEAK-Flash software. The bootloader is loaded by selecting the option yes and confirming with the Enter key . If no firmware update is performed within a period of 45 seconds, the PEAK-MiniDiag NMEA 2000 turns off.
3.3 Shield Voltage The PEAK-MiniDiag NMEA 2000 measures the current (Val), minimum (Min), and maximum (Max) DC shield voltage between the shield and the ground. The NMEA 2000 specification requires that the Shield and NET-C (GND) are connected together to the power supply. The shielding of the D-Sub connector is connected with high-impedance to ground (pin 3).
3.4 Common Mode Voltage The PEAK-MiniDiag NMEA 2000 measures the current, minimum, and maximum common mode voltage (CMV) for your network. The CMV is a shift of the signal voltages of NET-High and NET-Low without a change of their differential voltage. The common mode voltage should be within the voltage range of -2.5 V to 2.5 V. If this value deviates, disturbances may occur on the NMEA 2000 bus and the message flow may be impaired.

Check whether the PEAK-MiniDiag NMEA 2000 has been properly connected and terminated. Jumping value Check whether the PEAK-MiniDiag NMEA 2000 has been connected correctly.
3.9 Bit Rate The PEAK-MiniDiag NMEA 2000 is preconfigured at delivery with the NMEA 2000 default bit rate of 250 kbit/s and with a sample point of 80%. If the bit rate of the NMEA 2000 network is unknown, the Bit Rate function can be used to automatically determine the bit rate and associated sample point by using bit timing measurements.

CAN bus. yellow CAN frames are received with errors. Error rate too high. Check if the configured bit rate of the PEAK-MiniDiag NMEA 2000 matches the bit rate of the network. Tip: If the measurement of the bit rate remains unsuccessful, check the termination under Termination and the voltage values on the NET lines under Net Voltages.

(dominant). If the percentage value equals 0, the NMEA 2000 bus is in idle state (recessive) or not in operation. All values are reset when the PEAK-MiniDiag NMEA 2000 is switched off or when the function is exited. 3.10.3 Available Options...
4 Firmware Upload A new firmware version can be transferred to the PEAK-MiniDiag NMEA 2000. The firmware is uploaded via a CAN bus using the Windows software PEAK-Flash. Note: A firmware upload to the PEAK-MiniDiag NMEA 2000 should only be performed with battery supply and a direct connection from a computer to the PEAK-MiniDiag NMEA 2000.
Tip: You can click on the Show embedded firmware files link. In the list you can then see which firmware version is currently available. 3. Set the PEAK-MiniDiag NMEA 2000 to bootloader mode. If the device is switched off, hold down the arrow keys and the Enter key until the Bootloader appears.

7. In the drop-down menu Bit rate, select the nominal bit rate 250 kbit/s. 8. Click on Detect. In the list, the PEAK-MiniDiag NMEA 2000 appears with the firmware version. If not, check whether a proper connection to the CAN bus with the corresponding nominal bit rate exists and whether the CAN bootloader is active on the PEAK-MiniDiag NMEA 2000.

15. When the bootloader is finished, the PEAK-MiniDiag NMEA 2000 must be restarted via the Enter key Check under the function System Info whether the current version is displayed next to Firmware. You can now use the PEAK-MiniDiag NMEA 2000 with the new firmware. 4 Firmware Upload PEAK-MiniDiag NMEA 2000...
Appendix D Signal Level of a NMEA 2000 Bus The PEAK-MiniDiag NMEA 2000 provides two device functions for checking the NET lines NET-High and NET-Low. This appendix provides a brief explanation of the interpretation of the measurement results. Basically, a distinction is made between the recessive (passive) and the dominant (active) state for the signal level of a NMEA 2000 bus.
Appendix F Disposal The PEAK-MiniDiag NMEA 2000 and the batteries it contains must not be disposed of with household waste. Remove the batteries from the PEAK-MiniDiag NMEA 2000 and dispose of the batteries and the PEAK-MiniDiag NMEA 2000 separately and properly, according to local guidelines. The PEAK-MiniDiag NMEA 2000 contains the following batteries/rechargeable batteries: 3 x Micro AAA with 1.5 Volt not-rechargeable batteries or...
