1. Introduction

The I-7530A-MR is helpful for exchanging the data between the RS-
232/485/422 devices
communication modes: "Normal", "Pair Connection", "Modbus Slave" ,
"Modbus Master" (firmware version v2.00 or later), "Uart Switch".
(firmware version v2.10 or later)
In the Normal mode, the I-7530A-MR is designed to unleash the
power of CAN bus via RS-232/485/422 communication method. It
accurately converts ASCII format messages and CAN messages between
RS-232/485/422 and CAN networks. This mode let you to communicate
with CAN devices easily from any PC or programmable devices with RS-
232/485/422 interface.
In the Pair Connection mode, this module provides the transparent
communication between the RS-232/485/422 devices via CAN bus. The
application architecture may be as follows.

In the Modbus Slave mode, it allows a Modbus RTU master to
communicate with CAN devices on a CAN network. The following figure
shows the application architecture in this mode.
