ECAN-101 CAN485 Intelligent Bidirectional Converter CAN to 485 Serial to CAN Gateway , Rail Industrial Grade ModBus
[Introduction]：ECAN-101 is a small smart protocol conversion product independently developed by Ebyte. The product uses a wide voltage power supply of 8V ~ 28V and integrates 1 CAN-BUS interface and 1 RS485 interface, which can realize bidirectional conversion between CAN and RS485 different protocol data. This product supports five data conversion modes: transparent conversion, transparent conversion with logo, protocol conversion, Modbus RTU conversion, and custom (user). At the same time, the ECAN-101 intelligent protocol converter has the characteristics of compact size and easy installation. It has extremely high cost performance in CAN-BUS product development and data analysis applications. It is a reliable assistant for engineering applications, project debugging and product development.
