Unfortunately we do not have device codes for your non-DVR+ remote. These codes are not set by us but are set by the manufacturer of the universal remote control. We work with them to provide all of the commands for each individual key and they bundle them up and create a code that will work with there device.
Logitech/Harmony remotes do have our codes available to download to any of their Harmony remotes. https://www.logitech.com/en-us/harmony-universal-remotes
Please contact the remote control manufacturer for more information. In many cases they will have a code list in their instruction manual or on their website.
