|
| | == Аппаратная часть == |
|
| |
|
| == Hardware ==
| | Модуль построен на микросхеме физического уровня MCP2551. |
| | Сигналы CAN гальванически развязаны от контроллера. |
|
| |
|
| [[Файл:CAN.png|thumb|300px|CAN extension module]]
| | Устанавливается только в один слот - MOD1. |
|
| |
|
| The extension module uses MCP2551 physical layer interface.
| |
| CAN interface signals are galvanically isolated from the controller.
| |
|
| |
|
| Can be installed only to MOD2 extension slot.
| | == Распиновка == |
|
| |
|
| | Сигналы CAN выведены на клеммы модуля расширения O1-O3. |
|
| |
|
| The module contains a 150 Ohm terminator between the H and l lines. To enable it, you need to close the jumper on the top side of the Board.

| | |
| == Operation in UART-CAN mode ==
| |
| The WBE-I-CAN-ISO module operates in UART-CAN mode. The UART-CAN bus (also called sometimes simply CAN or RS-CAN) uses the physical can layer for the half-duplex serial port of the UART.
| |
| | |
| The UART-CAN bus is mainly used in metering devices such as Mercury energy meters.
| |
| | |
| In UART-CAN mode, the module can be installed in any expansion slot, so you can install two WBE-I-CAN-ISO modules
| |
| | |
| == Pinout ==
| |
| | |
| CAN signals are wired to O1-O3 terminal blocks.

| == Configuration == | | == Работа == |
| [[Файл:Hwconf-can.jpg|thumb|300px|CAN extension module]]
| | To be done |
| Configuration is set in the web interface: Configs section => Hardware Modules Configuration.
| |
| | |
| For CAN mode: in Internal slot 2, select "WBE-I-CAN-ISO" and click Save.
| |
| | |
| For UART-CAN mode: make sure that the corresponding slot (Internal slot 1 or Internal slot 2) is set to "None".
| |
| | |
| The device is detected immediately, no reboot is required.
| |
| | |
| == Operation ==
| |
| In CAN mode, it is defined as can1. About can on Linux, see [[CAN/en| CAN]].
| |
|
| |
|
| Module operates in UART-CAN mode identically to the RS-485 extension module, see [[Wiren Board 5: Модуль расширения RS485-ISO/en|description]].
