Overview The AWK-3121B wireless AP/client is the ideal rugged wireless solution for railway onboard/wayside and train-to-ground applications such as CCTV and CBTC communications. It can provide speeds of up to 300 Mbps with IEEE 802.11n technology. The AWK-3121B's can operate at temperatures ranging from -40 to 75°C and meet the requirements of the EN 50155/50121 regulations. - Page 3 Step 3: Set up the computer’s IP address Set an IP address for the computer so that it is on the same subnet as that of the AWK-3121B. Since the AWK-3121B’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0, set the IP address of the computer in the 192.168.127.xxx IP range and subnet mask to 255.255.255.0.
