If you updated LumenRadio TiMo firmware to 1.2.0.0 in an RC4 LumenDim device, and now the blue RF indicator is blinking slowly forever, or CRMX2 does not work, you MUST revert back to version 1.1.0.1. LumenRadio has been notified of this issue and they are working to correct it. Version 1.2.0.0 does not provide any useful advantages for RC4 LumenDim devices. Version 1.1.0.1 is fully compatible with CRMX2 when using a Stardust with up to 8 universes of DMX.
