DescriptionThe CR-801 module is designed to connect a 1-wire bus to an Ethernet network. The module is made in SFP format and can be installed in the corresponding slots of switches/routers or servers. On the 1-wire bus side, the product is a 1-wire network controller (1-wire master) and allows the connection of a wide variety of 1-wire sensors and actuators. On the SFP port side, the switch/router must support SGMII mode. Transport of ethernet packets between the module and application software, as well as power supply to the module and the 1-wire bus, is carried out through the mother switch.
The CR-801 module can be used in the following applications: - Temperature/humidity measurement/access control in server rooms
- Home automation
- Environmental monitoring
- Access control
