Hardware Configuration

1.1 Terminator resistor

According to the ISO 11898 specifications, the ISO 11898-2 CAN

Bus network must be terminated by two terminator resistors

(120Ω) for proper operation. If there are not only two terminator

resistors or only have one terminator resistor on the CAN bus,

the CAN network may be malfunction.

If users would like to enable or disable the terminator resistor

inside the I-7530, it is necessary to open the cover of the I-7530

and use jumper to do that. Here are the descriptions of how to

enable or disable the terminator resistor of the I-7530.

1.2 Power connection

Connect the (R)+Vs and (B)GND pins of the I-7530 module to the

DC power supply (10~30VDC).
