Is this for the Samsung Smart Control setup? Meaning, you want to control your TV and its connected external devices (Motorola) with your Samsung remote control? If not, ignore my post.
I'm assuming you've already connected the coaxial cable from your wall to your Motorola...AND...you've connected an HDMI cable from your Motorola to your Samsung.
Perhaps, instead of letting your Samsung auto-detect your Motorola, you can manually enter it as "DCH3200."
I found these procedures on http://www.samsung.com/us/support/answer/ANS00049377/
Control the TV and the Connected External Devices Together with Samsung Smart Control.
1. Connect the external device to control with the universal remote control to an HDMI port on the TV, and then turn on the external device.
2. Press the Home button on your Samsung Smart Control, to access the Home Screen.
3. Using the directional pad on your remote, navigate to and select Source.
4. Select Universal Remote Setup on the Source screen.
5. Select Start to set up your Samsung TV remote as a universal remote, so you can easily control all your devices.
6. Select device type to set up to control with your remote (Cable or Satellite Box, Home Theater System, Blu-ray player).
7. Follow the on-screen instructions to complete the setup and register the device. The on-screen instructions may vary, depending on the device type selected.
8. If the external device does not respond after being registered, register it again using its model number.
9. If the device is connected to the TV, select TV. If it is connected to a Home Theater System or Soundbar, select Home Theater System.
Note: To connect a Set Top Box, it must be connected via an HDMI cable. The TV will not recognize the STB if it is connected by coaxial cable.
