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).

If there are messages passed

through I-7532 from channel 1 to

channel 2, the CH1 Rx LED will

flash once with green light, and

vice versa.

(1).Transmission Fail： If the message

transmission fails on channel(X), the

CH(X) ERR LED will flash continuously,

and the flashing interval is about 100

millisecond.

(2).Buffer overflow ： If Tx buffer on

channel (X) had been overflow, the CH(X)

ERR LED would flash continuously, and

the flashing interval is about 1 second. No

matter the status is already fixed or not,

after users click the RST button, the LED

will be off.

(3).Bus Off：If the CAN bus connected to

channel (X) of I-7532 is bus off, the CH(X)

ERR LED will be ON until corrected.

5.RST & Err Clear

Reset & Error Clear Button

Click Clear Error LED

Press 3 sec Module Reset

(1).Error Clear：Users can click this button to

clear the ERR LED status.

(2).Module Reset：If users want to restart the

I-7532, press this button until 3 sec and all of

LED on I-7532 will flash once about 0.8 sec.

Users can use the “Baud Switch” to change the CAN1 and CAN2 baud.

There are 15 kinds of baud can be chosen. After changing the switch

value, users must reset Module to take the setting effect (press RST

button until 3 sec).

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:

The following connection statuses present the condition if the terminal

resistor is enabled (default) or disabled.
