Introduce The Product Of Modbus/RTU-CAN converter_GCAN

1. Introduction

1.1 Overview

GCAN-204 converter has one CAN-Bus interface, one serial interface. The GCAN-204 integrates the Modbus RTU protocol. With the GCAN-204 , user can use the serial bus connect to other equipment (with Modbus RTU protocol) access the CAN-Bus communication interface.

GCAN-204 has integrated isolation protection module. Using DIN railway fixed, it can be easier to integrate into the control cabinet.

2. Installation

2.1 Installation and fixation

GCAN-204 can be installed on a DIN rail, as shown in figure 2.1.



Note: DIN rails require to connect with ground wire.

GCAN-204 power interface definition, as shown in table 2.1.



2.2 Connect to Serial bus

GCAN-204 serial interface use RS485 interface. The pin definitions are shown in table 2.2.



2.3 Connect to CAN-Bus

The pin definitions for the CAN side of GCAN-204 are shown in table 2.3.



Only CAN_H and CAN_H connect with each other, then CAN_L and CAN_L connect with each other. Then we establish a connection.
