RS485 is currently a widely used communication interface in data acquisition and control applications where multiple nodes communicate with each other. RS485 is also the most versatile communcation standard in the standard series defined by the EIA.
In circumstances which require to use multiple readers, RS485 communication shows how it is important. With RS485 readers, you can reduce the cost of control panel and make the control much more accurate. RS485 Reader Series let you connect multiple readers to the control panel in one single RS485 port, which can enlarge the control panel card reader capacity. Also, RS485 has excellent transfer rate that allows long-distance transfer up to 1200m (theoretical value). Therefore, RS485 reader are perfect tool for multiple access solutions in scalable area.
