Login to Configuration Software
Connect BL102 to router or switch through WAN port with standard direct network cable or cross
network cable. Make sure BL101 and PC are in the same local area network. If it’s necessary to
connect the gateway to PC directly, use standard cross network cable to connect through BL101 LAN
port. (If BL101 is connected to PC directly, PC IP must be specified to 192.168.3.1 as default LAN IP
of gateway is 192.168.3.1 from factory setting)
Note: WAN port IP is retrieved automatically, LAN port IP is 192.168.3.1 from factory setting
Connecting BL102 to Router, Switch or PC with following way.

4.1.2 Search for Devices
Click Device Search to get all devices which are in the same local area network with PC. If no device
is found, please follow the procedure on the right notice box to check the root cause. Below is the
example of connecting Gateway BL102 with switch through WAN. A device with IP 192.168.1.164 is
searched out.
