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.
Figure 5: Terminator resistor
Therefore, the I-7530A 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-7530A cover and use the JP3 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)
