1. Introduction
1.1 Vue d'ensemble
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. L'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 Connexion au bus CAN
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.
