(4) Terminal resistor
Both ends of the main lines must always be terminated with a terminating resistor.
The physical characteristics of the terminating resistor are as follows:
Physical characteristics
Resistance: 121 Ω
Tolerance: ±1%
Permissible loss: 1/4 W
Type: Metal film
There are many ways to connect terminating resistors but it is recommended to use a
terminal block to connect a terminating resistor. Connect the terminal resistor to TB
only after soldering the appropriate solderless terminals to each end then cover with
Teflon tube. The terminating resistor need not be oriented but always connect it
between corresponding signal wires (CAN-H and CAN-L).
See the connection example of a terminating resistor below.

When connecting a terminating resistor to a terminal block (TB), always connect it
between corresponding signal wires (CAN-H and CAN-L). When the terminating
resistor is connected to different terminals, the communication may be disabled.
