Terminator resistor settings

According to the ISO 11898 specifications, the CAN Bus network
must be terminated by two termination resistances (120Ω) for proper
operation, as shown in the below figure.

Therefore, the I-7565 module supplies a jumper for users to connect
the terminator resistor or not. If users want to use this terminator resistor,
please open the I-7565 cover and use the JP4 jumper to activate the
120Ω terminator resistor built in the system, as in the following figure.
Note that the default setting is active.
Enable (default), (Activate) Disable, (Deactivate)
