I-7530 RS-232/CAN Converter User’s Manual (Version 2.5, Mar/2012) ------------- 9
2.4 Terminator resistor settings
According to the ISO 11898 specifications, the CAN Bus network
must be terminated by two termination resistances (120
Ω
) for proper
operation, as shown in the below figure.
Figure 5: Terminator resistor
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)
