EyeTV Channel Changer

D11/H20 and other DirecTV STB with a USB port

For these you will need a USB to serial adapter that is based on a Prolific PL2303.

Here are the cable known to work with the D11 and H20 (and the mac) :

• Sabrent SBT-USC1M
• GWC UC320
• Iogear GUC232A(that 's the one I have on my H20)
• ATEN UC-232A
• BAFO BF-810

Pick the least expensive one and buy 2 as they also work on the Mac.

For the mac you'll need to install the driver foudn here : (PL2303 Mac OS X Driver Download)

For the db9 female to db9 female (null modem) it's easy to find online or to build it yourself.

If all goes well you'll be start the program, configure the STB name, type and port and enable it. Then in EyeTV, change to one of the cannel configured for this STB and you should see it change channel. I haven't been able to test other STB of this type but it's probable that it will also work with the D11 series.

D10/RCA DirecTV STB with a 'low speed data' or 'home control' port (4P4C connector)

• For these STBs, you need a DB9 to 4P4C connector adapter for the STB (You can find some pre-made one here : DTV Control : Cables) and a usb to serial adapter for the Mac (see above in the D11/H20 section).
• If you are using an RCA receiver with a "Home Control" port, be sure it is set to "Low Speed Data" and not "Home Control".
  If your port is a 'low speed data' you don't need to do anything.
• I haven't been able to test other STB of this type besides mine (RCA DRD435RH) but it's probable that it will also work with the D10 series. For the usb to serial adapter on the mac look at the list of adapter for the D11/H20 above. Some receiver expect the channel to be send in multidigits form (send 002 instead of just 2) so select the number of digits you need and check the checkbox.

DirecTV Samsung SIR TS-360

The TS-360 has a RS232 port on the back so all you need is a DB9 male to DB9 female serial cable (same as for a modem) and one usb to serial adapter on the Mac (see adapters above in the D11/H20 section).

FireWire STB :

For these you will need a simple firewire cable to connect your cable box to your mac.

• First step is to configure a Set Top Box in EyeTV : EyeTV FAQ on how to configure a Set Top Box
• The name you give in the EyeTV Set Top Box configuration will have to be the same one you'll give in the ChannelChanger EyeTV Name field (seen screen shot above).
• The software will auto detect the connected box and set it in the Port section as the bottom.
• You need to select the firewire mode that works with your STB (Firewire keypad with or without key release or Firewire direct). Some STB support both, some only one mode.
• Click on "Enable" and save your preferences. From now on , when a recording starts (or you change channel on the live window), your cable box will change to the right channel.
• If you need to use AVCBrowser or any other FireWire AVC recording application, you might want to uncheck the "Constant connection (FireWire)" check box so that ChannelChanger only open the device when it needs to change channel. This will allow you to leave ChannelChanger running and use one of these other application. When you change channel, if you're using an Hauppauge HD-PVR or an EyeTV HD, you will notice a 4/5 second delay before you see the actual change. This is not the time it actually take to change channel but the time these device need to get the video encoding going.

Support and request :

• If your STB works send me an email so that I can build a list of tested device.
• If you'd like me to add a device, I need the protocol documentation and a ssh access to a box where the STB is connected (USB to serial, firewire, Ethernet, ...).
