The DirecTV D10 model has been in production for several revisions. Because of this it has been manufactured by several different manufacturers each having specific features.

There is ONLY one model of D10 that is supported by ReplayTV, that model is the D10-100.  The other versions of the D10; the D10-200, D10-300, D10-400, etc. will not accept serial commands from the ReplayTV as the serial port has been disabled on the later models.

Furthermore the D10-100 is ONLY supported using the Serial APG [Advanced Programming Guide] command set. The Serial APG command set is ONLY available on the 5xxx models using the latest software version 5.1 build 144.

The Serial APG command set is not available on 2xxx, 3xxx or 4xxx models. The D10-100 Satellite Box can ONLY be used with a 5xxx model. 

A company named Paterson Technology used to make a translator for converting Serial commands to Serial APG commands for the 2xxx, 3xxx or 4xxx models; however, they have ceased to manufacture that version.  They do manufacture a version to work with the DirecTV H20 and D11 Satellite Boxes which are currently shipping from DirecTV.

Additionally, there is not an IR Blaster code available for any of the D10 models.
