EVB-A100 User Manual 1. Overview EVB-A100(VB) is a product that plays as a bridge between Ethernet LAN or WLAN and a wireless network. This product is connected with the Tx (Client) device such as multiple IP cameras and uses Rx (Master) for monitoring from NVR or PC. 1.1 Functions and Features (1) Network function Provides TCP/IP protocol. Supports video, audio, alarm, voice data, and serial device data service. If a web browser is installed, IE can be used for access as transmission is made possible through the TCP/IP network. (2) General applications ATM machines, factories and banks that need network (digital) monitoring Nursing and school services that need remote monitoring Intelligent gate system or external device monitoring Bridge and traffic system monitoring, river or wood monitoring to prevent natural disasters (3) Settings EVB-A100 can be set to Rx or Tx. A Rx (Master) is combined with one or multiple Tx’s (Client) to form a transmitter-receiver system. Tx transmits data (image and voice data from IP camera) that come into the Ethernet LAN. Rx receives wireless data from Tx and sends it to the Ethernet LAN port. NVR or PC can receive and process the data. This product includes the latest WiFi technology - 802.11ac 5GHz. -4EMW Co., Ltd.

Terminology Rx(Master) Tx (Client) SCS VSP RSSI Wi-Fi Wireless Bridge Association SSID WEP Bandwidth DHCP Static IP 802.11ac PHY WDS BSS Rx is a receiver which connects wired and wireless connectivity. A transmitter is connected to a receiver. Smart Channel Selection Video Stream Protection Received Signal Strength Indication A mark for WECA to check linking between wireless products. The name is originated from "Wireless Fidelity". WECA carries out an elaborate test and grants a Wi-Fi logo to a product that satisfies the linking standards. Tx (Client) or Rx ( Master) that uses a wireless network to connect between two different wired networks. Has a table that controls the packet route between Rx and Tx Maintains Rx and Tx. Service Set Identifier SSID is a unique identifier of 32 bytes length added to the header of a packet transmitted through a WLAN. It is used like a password when Tx connects to BSS (basic service set). Rx or Tx must the same SSID. A Tx that does not know the unique of a certain BSS cannot access the BSS. WEP (Wired Equivalent Privacy): An encryption standards prepared by IEEE 802.11 for WLAN security. There are various types of application developed to use encryption keys to strength security. Refers to the difference between the highest and lowest frequencies of a signal usable in a network. It means, commonly, the highest transmission speed or a capacity to transmit information and uses ‘bps’ its unit. DHCP allows the network administrator to manage and allocate IP addresses and to send new IP addresses when the computer connects to a different location of the network. Can use fixed IP addresses. There is no need for the administrator to allocate IP addresses. 802.11ac operates at 5G Hz’s V10.1 frequency bandwidth. The lowest sub layer of the physical layer and a block for connection with the outside. It changes a protocol layer into a physical layer. Wireless Distribution System WDS forms a wireless network between Rx’s to provide the larger support range of wireless network than when one Rx is used. Base Service Set Refer to a minimal size of WLAN formed based on a Rx if a wire network consists of multiple wireless Rx’s in the infrastructure mode. - 37 EMW Co., Ltd.

Flexible Authentication via Secure Tunneling Initialization Vector Protected EAP Pre-Shared Key Temporal Key Integrity Protocol Transport Layer Protocol WiFi Protected Access WIFI security Protagoras WEP -> WPA - WPA2 Wi-Fi Protected Access (WPA, WPA2 ) is an authentication program carried out under the monitoring of Wi-Fi Alliance. It is a security protocol that indicates that the network equipment satisfies the security protocol established by Wi-Fi Alliance. WPA indicates that the existing LAN card operation complies with the expansion protocol standards completely and WPA2 mark indicates that the relevant device does the same. WiFi Protected Setup Press the WPS buttons of the wireless Rx and wireless device (during the 120 seconds of waiting time) to establish connection without entering password: there are PBC, PIN, and NFC type. Protected Management Frames Protects the frame. Remote Authentication Dial-in User Service Number of Spatial Streams Delivery traffic indication message Short Guard Interval The guard interval is a waiting time between sending data continuously in a wireless network to reduce the impact of data. For 802.11 a/g, it is 800 nsec, but for 802.11n, it is set to 400n sec so that the sub carrier can be used to compensate for the reduced guard interval to make the total throughout to reach 72Mbps. Reducing the guard is provided as a optional when a WLAN is established as interval needs agreement between the transmission and reception ends. Orthogonal Frequency Division Multiplexing Multi Input Multi Output MIMO is a multi I/O technology. The wireless quality depends on how far the signal is and which route the signal is received. MIMO uses multiple antennas to receive signals coming in along multiple paths (multipath) and operate data and recover them to original signals. 802.11g/b/g uses a single antenna or SISO (Single Input Output). It is used instead of password to mean that the password should long enough. - 38 EMW Co., Ltd. EVB-A100 User Manual 10.
