Introduction of CANopen-RS485 converter_GCAN

1 Introduction

1.1 Overview

GCAN-301(CANopen-RS485) has one standard CAN-Bus interface and one standard RS485 interface , it can realize the RS485 equipment as CANopen slave station access to CANopen network. It's a custom product.

1.2 Properties at a glance

CAN-Bus interface adopts German CiA standard OPEN4 interface form

The built-in CANopen protocol stack follows the protocol description document, DS 301

The CANopen node number is 32(customizable), which can be configured by software

CAN-Bus baud rate is 250Kbps by default(customizable), which can be configured by software

CAN-Bus isolation module insulation voltage: DC 1500V

Standard asynchronous 485 communication: 1 start bit, 1 terminator bit, 8 bits data(customizable)

485 interface baud rate of 9600bps, the communication cycle is 500ms, with accumulation and calibration(customizable)

485 interface adopts OPEN - 4 terminals

232 interface (OPEN - 4 terminals for upgrade)

Power supply voltage: 9 ~ 30V DC, the maximum current is 20mA, with the rectifier bridge, the terminal is OPEN - 4

Installation method: DIN guide rail

Working temperature range from -40 to 85 °C

Size: (L)113mm * (W)100mm * (H)21mm

2. Installation

2.1 Installation and fixation

GCAN-301 can be installed on a DIN rail, as shown in figure 2.1.


 
Figure 2.1 GCAN-301module installation

Note: DIN rails require to connect with ground wire.

GCAN-301 power interface definition, as shown in table 2.1.



2.2 Connect to Serial bus

GCAN-301 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-301 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.
