Slave station communication port supports up to 250 nodes
        The OX-2201 dual cache isolated RS485 hub is a communication device that supports dual RS485 master devices and one or multiple RS485 slave devices. Used to solve the problem of communication conflicts caused by two master stations communicating with slave stations simultaneously. When master station 1 queries slave station data, it will only return to master station 1 and not to master station 2. Similarly, when master station 2 queries slave station data, it will only return to master station 2 and not to master station 1. The interface between the master station and the slave station adopts optoelectronic isolation technology to protect the master station equipment from interference. The circuit design includes 15KV ESD protection and 5KA lightning surge protection devices, which can effectively isolate the harm caused by lightning strikes and static electricity to the equipment. Each of the three communication interfaces has a communication indicator light, which can visually display the status of each communication port. Transparent data transmission between the master and slave interfaces, communication format and baud rate can be set through software.
       This product is suitable for comprehensive RS485 communication systems such as automation control systems, monitoring systems, alarm systems, access control systems, IC card charging, meter reading, one card, parking lot charging, etc.
