Route Detecting: Detecting the destination host IP address, if there is no response at the set time interval and times, the router will switch over to the selected backup route.
When the "Radio" is set to the default route and the backup routing function is enabled, we recommend setting the operator's gateway as the destination IP address for detecting.
When the "Ethernet" or "COM" is set to the default route, we recommend setting a reliable host in the Internet as the destination IP address. Meanwhile, set the “Back Time” to force the backup route to be switched back the default route.
Attention: The destination host should work reliable. Otherwise, it will cause the router switch over frequently.
Backup route: There are two options.
Gateway - When the "Enable Gateway" is enabled, the traffic will be routed to this gateway via the Ethernet interface if the default route failed. The gateway IP address is the network gateway IP address that Galaxy router is connected.
COM - When the "COM" port is enabled, the traffic will be routed to Galaxy router COM port if the default route failed, and then the connected modem will dial a number that specified at COM port setting.

Click the "COM Port Setting" button to this setup page.
At this page, set up the COM port interface and the dialup parameters. Because of the COM port may be connected with different types of modem, it provides a script filed to
For example, dial a number 83890677, fill in the below code at the “Dial Script” filed.
"" at
OK atxxx
OK atd83890677 TIMEOUT 30 CONNECT ""
atxxx is the modem extra command that may be used (depends on the connected modem). It should be filled in with the connected modem parameter.
All extra AT commands should be added before dialing. In other words, all extra AT commands should be added before the atd command.
If the telephone line is behind a PABX, it may be needed to dial a "0" and waiting the dial tone. The atd command should be:
atd0,83890677
The COM port will try to dial the backup channel. If it fails the connection for 3 times, the router will switch back to the default routing and try another sequence.
The route status will be displayed on the front panel LED.
