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

Figure 2.1 GCAN-301module installation
Примечание: DIN-рейки требуют подключения провода заземления.
GCAN-301 power interface definition, as shown in table 2.1.

2.2 Подключение к последовательной шине
GCAN-301 serial interface use RS485 interface. The pin definitions are shown in table 2.2.

2.3 Подключение к шине CAN-Bus
The pin definitions for the CAN side of GCAN-301 are shown in table 2.3.

Только CAN_H и CAN_H соединяются друг с другом, затем CAN_L и CAN_L соединяются друг с другом. Затем мы устанавливаем соединение.
