Step 1: Add new device

Step 2: Fill in details but ignore IMEI

About
The device configuration PC software is a comprehensive package supporting all Windows versions back to XP - Win10/11.
PC programming is useful for adding a batch of proximity fobs in 'virtual card reader' mode. All fobs can be quickly stored to the unit before uploading to the web browser app, the best method for ongoing system management.
The Legacy Method
The SMS configuration method has been surpassed by the web, app and PC methods due to the complexity of configuration options – especially in the time-restricted access control products.
That said, SMS is a quicker way to do checks and minor changes than all other methods.
SMS commands are typically used to find out current settings, make a quick edit, or get operational info, like signal strength, usuaully within a few seconds.
It's a very handy fault-finding tool and also transaltes over to 'Terminal' apps such as TeraTerm (recommended) allowing you to use SMS commands over the USB interface. It's what we use in-house for easy fault finding and diagnostics.
A list of SMS parameters are available in the device manuals. A cheat sheet will be available on the product page.
