[Introduction]：E810-R18 is an isolated repeater (HUB) for 1-channel RS-485 to 8-channel RS-485 launched by Ebyte. RS485 hub is a communication device that supports 1-channel RS-485 master device and 8-channel RS-485 slave devices. Photoelectric isolation technology is used to protect the master and slave devices from interference. No configuration is required, and transparent data transmission between the master and slave interfaces. This product is suitable for comprehensive RS485 communication systems such as automation control systems, monitoring systems, alarms, access control systems, IC card charging, meter reading, one-card pass, parking lot charging, etc.
