Page 19: Examples Of Conversion Patterns
USR-CAN114/112 User Manual Setup Software Schematic 4. Examples of conversion patterns 4.1. Transparent Conversion In the transparent conversion mode, CAN114/112 receives data from one bus and immediately converts it to the other bus side without adding data or modifying the data. This enables the exchange of data formats without changing the data content, and the converter is transparent to both ends of the bus. -

Page 26: Modbus Protocol Conversion
USR-CAN114/112 User Manual Standard Protocol Transmission Examples 4.4. Modbus protocol conversion Modbus protocol conversion can convert the standard Modbus RTU serial data protocol into a specific CAN data format, which generally requires CAN bus device messages to be editable. The converter uses the standard Modbus RTU protocol format on the serial port side, so the converter not only supports users to use Modbus RTU protocol, but also can be directly connected to other devices that support Modbus RTU protocol. - Page 27 USR-CAN114/112 User Manual Segmented Protocol CAN frame information (remote frame or data frame; standard frame or extended frame) is set by configuration software. The Modbus protocol content of the transmission can start from the "data 2" byte, if the protocol content is greater than 7 bytes, then the remaining protocol content will continue to be converted according to this segmented format until the conversion is completed.
