Terminator Resistor - ICP DAS USA tM-7565 User Manual

2.5 Terminator resistor

According to the ISO 11898 specifications, the ISO 11898-2 CAN Bus network must be
terminated by two terminator resistors (120Ω) for proper operation, as shown in the below figure.
If there are not only two terminator resistors or only have one terminator resistor on the CAN bus,
the CAN network may be malfunction. About the terminator resistor of the I-7530-FT (follows the
ISO 11898-3 specification), each I-7530-FT has its own terminator resistor. Users don't need to
take care about that.

If users would like to enable or disable the terminator resistor inside the CAN converters, it is
necessary to open the cover of the CAN converters and use jumper to do that. Here are the
descriptions of how to enable or disable the terminator resistor of the CAN converters.
