dear woolifer ,
I am not an expert but i hope i can help you..
is it youmean digital cablebox?
if it is try this-
This is a problem a lot of people have with coaxial-only televisions because DVD players do not have coaxial (RF) outputs, which means they can't be connected directly into a television with only a coaxial (RF) input. The solution is to purchase a RF modulator, which is a small device that will convert the AV output from the DVD player to coaxial (RF).
As for the instructions, I am going to assume the DVD player is not a combo unit with the VCR, and that you want to record TV on your VCR. Step 4 will include connecting your DVD player, but if the DVD player is a combo unit with the VCR, just ignore step 4 part as DVD connection will be included in the VCR set up. Actually, you wouldn't need the RF modulator if it is a VCD/DVD combo unit.
- Connect the coaxial cable coming out from the wall to your digital cable box in the ‘video in’ slot. It might also be labeled ‘antenna in’ or ‘cable in’.
- From the cable box, connect a coaxial or composite (yellow video cable) and stereo (red-white) RCA audio cables to the VIDEO IN terminal on your VCR.
- From the VCR, you will have to connect this to the RF Modulator using a coaxial cable from the VIDEO OUT on the VCR to one of the IN ports on your RF modulator.
- You can now connect your DVD player to the RF Modulator by using the yellow-red-white composite/RCA cables from the VIDEO OUT on the DVD player to another port on the RF modulator.
- From the RF modulator, connect this unit to your TV by using a coaxial cable. It will be from the VIDEO OUT on the RF modulator to the VIDEO IN or CABLE or ANTENNA IN port on your television.
This should be all you need to get started watching your digital television. In simple terms here is what you did:
Coaxial from wall to cable box
Cable box to VCR
VCR to RF modulator
DVD player to RF Modulator
RF modulator to TV
You will only be able to record what is on channel
