1. Introduction
I-7532 is a local CAN bridge used to establish a connection
between two CAN bus system in a CAN network. The I-7532
stands by itself connecting adjacent wiring segments together as in
the case of a CAN repeater (I-7531). Not just like a CAN repeater,
I-7532 has more powerful features (Extend Network Distance and
Connect two networks with different baud rate).

4. Terminator Resistor Setting
The I-7532 module includes two build-in 120Ω terminal resistors, users
can decide to enable those two terminator resistors or not.
The JP4 of I-7532 is used to adjust terminal resistor on CAN Channel 1,
and the JP3 of I-7532 is used to adjust terminal resistor on CAN Channel 2.
Before adjusting JP3 or JP4 of I-7532, users need to open the cover of
I-7532 first. Those locations of JP3 and JP4 are shown as follows:
JP4
JP3
The following connection statuses present the condition if the terminal
resistor is enabled (default) or disabled.
Disable
(Deactivate)
Enable
(Activate)
