User Manual - QG65N2 SAE J1939 Inclinometer (Type JB) V1.1 4.4. CAN termination A CAN bus should be terminated properly to prevent signal reflections. The QG65N2 J1939 Inclinometer has an internal 120 Ohm termination resistor. By default, this is disabled. -
Page 10: Functional Description
6. Functional description 6.1. Inclination measurement principle QG65N2 Inclinometers measure inclination by measuring static acceleration of gravity using an accelerometer MEMS. In static conditions, inclination measurement by this principle is accurate and reliable. However, the vibrations or movements present on almost all industrial machines generate undesirable g-forces. -

User Manual - QG65N2 SAE J1939 Inclinometer (Type JB) V1.1 11-bit identifier devices can be used within the same network without conflict, but it’s not defined in J1939 standards. 7.3. PGN (Parameter Group Number) The J1939 PGN comprises an 18-bit subset of the 29-bit extended CAN ID. The PGN uniquely identifies the parameter group (PG) that is being transmitted in the message. - Page 23 User Manual - QG65N2 SAE J1939 Inclinometer (Type JB) V1.1 DA: defines the specific address to which the message is being sent.
