3.1 USB 2.0 Data Ports

All new DIRECTV STBs have USB 2.0 data ports. The STB USB port has a host configuration. Serial
commands are interfaced through the data port using a USB-Serial adapter. The following RS-232­compatible serial port adapters will be supported:

Table 3-2: USB-Serial Adapter

Manufacturer Model USB Vendor ID USB Product ID

IOGEAR GUC232A 0x067B 0x2303
ATEN UC-232A 0x067B 0x2303
BAFO BF-810 0x067B 0x2303

The USB port on most STBs support hot-plug. That means USB ports will work any time when a
USB-serial adapter is plugged in. Only the HR20 and HR21 USB ports works differently. The USB­serial adapter must be plugged before the STB is booted. If the USB connector is plugged in when the

STB is running, it must be reset.

3.2 Data Port Interface Default Baud Rate

All STBs have a default baud data rate of 9600. The data format is 1 start bit, 8 data bits, no parity, 1
stop bit, and no handshaking.

4.4 Multi-Tuner Data Port Commands

A new set of commands are introduced for multi-tuner STBs, such as R15 and HR20. For multi-tuner
STBs, the tuner needs to be identified for many of the commands as an input parameter. To maintain
backward compatibility, new commands with the suffix “MT”, have been created that have a TunerID
parameter added. In the case where an original non TunerID command is issued to a multi-tuner STB,
it will be executed as the equivalent “MT” command with TunerID set to 0x01. The [TunerID] shall
start at 0x01 and increase in value by one for each additional tuner (i.e. 0x01, 0x02, 0x03…). The
[TunerID] can be obtained by issuing the command GetTuner. See Table 4-1 for the list of STBs that
support the multi-tuner commands.

0x9A GetTuner Get the number of tuners and their designations.
0x8A GetPrimaryStatusMT Get the status information of current channel.
0x8B GetCurrentChannelMT Get the major and minor numbers of the tuned channel.
0x9D GetSignalQualityMT Get the signal level for the tuned channel.
0x9F OpenUserChannelMT Tune to a channel by inputting a channel number.

4.5 Default Data Rate and Format

All STBs have a default data rate of 9600. The data format is 1 start bit, 8 data bits, no parity, 1 stop
bit, and no handshaking.

4.6 Command Protocol

The STB will use the command and data acknowledgment protocol for flow control as specified in
Figure 4-1.

Any controller that is implemented to control DIRECTV STB, should follow the protocol depicted in
Figure 4-1.
