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-7530 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-7530 cover and use the JP3 jumper to activate the 120
Ω terminator resistor built in the system, as in the following figure. Note
that the default setting is active.
Enable (default), (Activate) Disable, (Deactivate)
