3 Data Port Connectors
Table 3-1 shows what type of connector and data rate the STB data port has. Table 3-1: Type of Data Port Connector STB Model Type of Data Port Connector Data Rate (baud) D10 D11 H10 R15 HR20 RJ22 USB RJ22 USB USB 9600 9600 9600 9600 9600
3.1 Low-Speed Data Port Connector
The connector type on D10 and H10 is a standard DB-9F or RJ22 (4 way/4 position jack). The pins for the DB-9F are as shown in Figure 3-1. The STB will use three (3) lines (L2-Rx, L3-Tx and L5-Grnd) for bi-directional full-duplex communications.
Figure 3-1. Low-Speed Data Port Pin Assignment Diagram Line positions, designated as “optional”, may be provided (but are not required to be provided) DIRECTV Proprietary Version 2.0 March 2, 2007 DTV-MD-0058

by the STB as a convenience to source a “TRUE” state to those PC serial interface lines that may require a “TRUE” state for data transfer. Figure 3-2 shows the orientation of the RJ22 (4 way/4 position jack).

3.2 Low-Speed Electrical Performance and Characteristics
The low speed timing characteristics are defined in Table 3-2. Table 3-2: Timing Characteristics Parameter Bit Timing Total Character Interval Requirement 104 μs ±7 μs 1.04 ms ± 8 μs
3.3 Bit Timing (Start, –D0 TO –D7, and Stop)
The STB complies with the bit timing requirements as shown in Figure 3-3.

DIRECTV Set-Top Box Information for the Installer
3.4 Idle Interval, General
The general idle interval is a minimum of zero (0) msec. The maximum idle interval will be determined by the rate of transmitted data and internal STB processes when the port is “opened,” or is determined by the service command parser when the port is “closed.”
3.5 Idle Interval for Non-Empty STB Buffer
The idle interval will not exceed 30 ms as long as at least one byte exists in the STB receive buffer, given that the port is “opened.”
3.6 Low-Speed Input Characteristics
3.6.1 Input Signaling Characteristics (Pin 3) The low-speed data port will comply with the input signaling characteristics shown in Table 3-3. Table 3-3: Input Drive Characteristics Parameter Space voltage Mark voltage Terminating impedance resistance Capacitance C < 150 pf Specification +3.0 volts min, +25 volts max -25 volts min, -3.0 volts max 6K < R < 7K resistive to ground
3.7 Low-Speed Output Characteristics
3.7.1 Output Drive Characteristics (Pin 2) The STB output drive characteristics are as shown in Table 3-4. Table 3-4: Output Drive Characteristics Parameter Space voltage Specification +5.3 volts max at Ioh = 0 mA, +3.0 volts min

-6.0 volts min at Iol = 0 mA, -3.0 volts max, 3k < R < 7k resistive to ground C < 2500 pF
3.7.2 Passive Outputs (Pins 1, 6, 8, and 9) (Optional) If the data port optional pins one (1), six (6), eight (8) and nine (9) are provided, the passive outputs will be as shown in Table 3-5. Table 3-5: Passive Drive Characteristics Parameter Output Specification -2 mA ±20% at + 3 volts and –10 mA ±20% at –5 volts
3.7.3 Low-Speed Signaling Conventions The data port signaling conventions will be as listed in Table 3-6. Table 3-6: Low-Speed Data Port Signaling Conventions Interchange Voltage Binary state Signaling state Function Negative or Positive 1 or 0 mark or space OFF or ON
The idle state for data port pins two (2) and three (3) will be “mark”.
3.8 USB 2.0 Data Ports
All new DIRECTV STBs have USB 2.0 data ports replacing the DB-9F or RJ22 data port connectors. The STB USB port has a host configuration. Serial commands are interfaced through the data port using a USB-Serial adapter. The following RS-232-compatible serial port adapters DIRECTV Proprietary Version 2.0 March 2, 2007 DTV-MD-0058
Page 11 of 41
DIRECTV Set-Top Box Information for the Installer
will be supported: Table 3-7: USB-Serial Adapter Manufacturer IOGEAR ATEN BAFO Model GUC232A UC-232A BF-810 USB Vendor ID 0x067B 0x067B 0x067B USB Product ID 0x2303 0x2303 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’s USB port works differently. The USBserial adapter must be plugged before the STB is booted. If the USB connector is plugged in when the HR20 is running, it must be reset.
3.9 Low-Speed Data Port Interface
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.

GetCurrentChannel GetSignalQuality GetCurrentTime GetUserCommand EnableUserEntry DisableUserEntry GetReturnValue Reboot SendUserCommand OpenUserChannel Get the major and minor numbers for the tuned channel Signal level for the tuned channel Current time in UTC Get the remote or front panel command input by the user Allows direct control of the STB by the remote or front panel buttons Disables direct control of the STB by the remote or front panel buttons Returns the last Return Value issued by a data port command Commands a reboot Send remote control commands through the data port Tune to a channel by inputting a channel number
This command holds its value after a warm start. Other commands are terminated.
4.4 Multi-Tuner Data Port Commands
A new set of commands are introduced for multi-tuner STBs, such as R15 and HR20. For multituner 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 DIRECTV Proprietary Version 2.0 March 2, 2007 DTV-MD-0058
Page 15 of 41
DIRECTV Set-Top Box Information for the Installer
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 issue the command GetTuner. R15 and HR20 STB support the multi-tuner commands. Table 4-4: Multi-Tuner Commands Summary Comman d Code 0x9A 0x8A 0x8B 0x9D 0x9F Command Label GetTuner GetPrimaryStatusMT Description Get the number of tuners and their designations.

GetCurrentChannelMT Get the major and minor numbers of the tuned channel. GetSignalQualityMT OpenUserChannelMT Get the signal level for the tuned channel. 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.

The STB will execute a GetPrimaryStatus command by providing the STB’s health and status as defined by the Return Data Stream parameters. The STB will provide current time in Universal Time Coordinate (UTC) unconditioned by time zone and daylight savings settings. The fields ROMVer3, ROMVer2, ROMVer1, ROMVer0, STS ID0, STS ID1, STS ID2, STS ID3, STS Ver are private. The CAM ID is returned in hexadecimal with zeroes stuffed into the most significant positions to fill out the unused bits. For example, a CAM ID = 0013 1751 9641 in hex is 0x4E87C119. This command would return 00 00 4E 87 C1 19 for the CAM ID. The RID ID is returned in hexadecimal with zeroes stuffed into the most significant positions to fill out the unused bits. For example, a RID = 0001 7035 6778 in hex is 0xA27702A. This command would return 00 00 0A 27 70 2A for the RID.

The STB will execute a GetUserCommand command by providing the remote control or front panel key presses via the Return Data Stream. The DisableUserEntry command will be called prior to calling the GetUserCommand command. If a user command has transpired since the last GetUserCommand request, the user command Type, Device, and Contents are placed in the return data stream. If a user command has not been made since the last request, the NACK_FCNOK is returned instead. The GetUserCommand is used to identify the type, device and key. For example, if the user pressed and released the Select (0xC3) key then one GetUserCommand is required. The GetUserCommand provides a Type of 0x00 (Key Toggle), Device of 0x01 (Remote) and Key of 0xC3 (Select key). On the other hand, if the user pressed the Select (0xC3) key, held it so that the remote repeats the command, and then released it on the remote control, two (2) GetUserCommands are required. The first GetUserCommand provides a Type of 0x01 (Key Down), Device of 0x01 (Remote) and Key of 0xC3 (Select key). The second GetUserCommand provides a Type of 0x03 (Key Up), Device of 0x01 (Remote) and Key of 0xC3 (Select).
