InstaShowTM Series network architecture The InstaShowTM Series is a system with security, its system architecture completely matches data confidentiality, system completeness and functional availability. Network transmission methods are divided into physical networks and wireless networks. Physical networks have the advantage of absolutely free from interferences, wireless networks in general environments and spaces will be mostly subjected to electromagnetic interferences from neighboring frequency bands.As such the InstaShowTM Series has been treated to lower electromagnetic interferences to make electromagnetic waves not interfere with normal operations of wireless projections and is very suitable for enterprise conference and office applications. The system architecture of the InstaShowTM Series has: physical layer, network layer, application layer.We will explain in detail each of the layers of the architecture. InstaShowTM Series Network Layer InstaShowTM Series Suite Application Layer HTTP, Encode/Decode Other flow controls Network Layer TCP/UDP,ICMP,IP,ARP Physical Layer Ethernet, MAC address HDMI/DisplayPort, Wi-Fi 1. Physical layer The physical interfaces supported by the InstaShowTM Series include USB Type A/USB Micro-B, HDMI/USB Type-C (DisplayPort alternate mode) and RJ-45 (Ethernet) . Intruders might analyze the firmware program through the physical layer and load malware on the device.Therefore protecting the physical interface port of the device is equally important as protecting the other layers of the system. USB Type A: Only provides the Button with DC 5V/0.9A power, does not support simplex/duplex data transmission functions. The USB Type A of InstaShowTM S supports HID command transmissions, but does not support simplex/duplex data transmissions. USB Micro-B: Only provides Host with DC 5V/1.5A power, does not provide simplex/duplex data transmission functions. 12 January 2020
