If you own ThinMan Repeater software you can manage it normally from the ThinMan version 7.8.9 or higher.
You can also update it to the new Gateway model G1000W using the .exe installer file and performing the ThinMan Gateway Update operation.
Load the Gateway .exe installer file into the ThinMan Package Repository (menu "Tools" → Package Repository").
For more details about ThinMan Package repository see Package Repository Menu.
Right-click on the repeater and select the "ThinMan Gateway Update" operation.
Select the ThinMan Gateway installer and click "OK".
Click on "Yes" to confirm the operation.
Wait until the operation has status "Succeeded" in the Task area and the model is "G1000W" (previously: "TMR").
The Repeater instance is now converted to a Gateway instance.
