Set the mode switch to WISP.
Connect an Ethernet lead between the TP Link device and the Key Cabinet.
Plug in the power connection to the TP Link device. Its a USB connection which will immediately power on the unit once plugged in.
As per step 3 of the manual, on a laptop or computer with WiFi capabilities, connect to the TP Link access point. Note that the password (secret key) is found on a sticker located on the side of the device.
Open a web browser and go to http://192.168.0.254. Note the password is admin.
Follow the screen shots found in step 4, part 2 "WISP Client Router Mode".
Once connected, reboot the key cabinet so that is picks up a new network address.
Log in to PoolCar and go to the Sysadmin menu.
Click "Manage Units" the heading "KeyMaster". Observe the current date/time the cabinet last synchronized with the server. Refresh the page after a while to see if the date/time stamp refreshes - the cabinet will synchronize every 30 seconds.
