== | == 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 | |||

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. | |||

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]]. | |||
