1.2 Scope
This document provides information on the DIRECTV Set-top box data port, front panel, and
remote control commands as an aid for installers, and auxiliary devices. This document is
relevant to set-top box (STB) models D10-100, D10-200, D10-300, D11, and H10. Other
models are not supported by this document.

3 Data Port Connectors
Table 3 shows what type of connector and data rate the STB data port has.
Table 3: Type of Data Port Connector
STB Model Type of Data Port Connector Data Rate (baud)
D10-100 RJ22 9600
D10-200 RJ22 9600
D10-300 RJ22 9600
D11 USB 115200
H10 RJ22 9600
3.1 Low-Speed Data Port Connector
The STB connector type will be a standard DB-9F or RJ22 (4 way/4 position jack). The pins for
the DB-9F are as shown in Figure 1. The STB will use three (3) lines (L2-Rx, L3-Tx and L5Grnd) for bi-directional full-duplex communications. Figure 2 shows the orientation of the RJ22
(4 way/4 position jack).
Line positions, designated as “optional”, may be provided (but are not required to be provided)
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.

3.2 Low-Speed Data Port Interface
The STB low-speed data port is a PC compatible serial port, and functions as a subset of RS-574.
The intended use is for direct connection to a PC or other equipment, allowing exchange of
control and data between the STB and that equipment using specialized software. For successful
communications with the STB, some PC serial port interface cards may require that their flow
control lines be strapped internally as “enabled,” and thus disconnected from any external flow
control signaling. Additionally, those PC serial ports incorporating a buffered 16550 UART
may be least likely to experience communications problems.
DIRECTV Proprietary November 17, 2005
Version 1.1.a Page 9 of 49 DTV-MD-0058
Page 10
DIRECTV Set-top box information for the installer
The majority of 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.
3.3 Low-Speed Electrical Performance and Characteristics
The low speed timing characteristics are defined in Table 4.

Total Character Interval
104 µs ±7 µs

3.4 Bit Timing (Start, –D0 TO –D7, and Stop)
The STB complies with the bit timing requirements as shown in
Figure 3.
Total Character Interval
Start Bit
8 Data Bits
D0 D7 Idle
Stop Bit
Figure 3. Bit Timing Diagram
3.5 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.”
3.6 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.”

3.9 USB 2.0 Data Ports
All new DIRECTV Set-top boxes (STB) have USB 2.0 data ports replacing the DB-9F or RJ22
data port connectors. The STB USB port has a host configuration. USB 2.0 data ports may have
a default baud rate of 9600 or 115200 in new models. Serial commands are interfaced through
the data port using a USB-Serial adapter. The following RS-232-compatible serial port adapters
will be supported:

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. The GetPrimaryStatus 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. The GetPrimaryStatus command would return 00 00 0A 27 70 2A for
the RID.

ACK_FCNOK : Success

0x0000 : Success
Non-Zero : Failure – No User Command available since last request
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).

The STB will execute a SendUserCommand command by sending the defined user
command to the user interface task.
This operation can take place whether command DisableUserEntry (0x13) is active or
not. The STB will respond to the user command as though a user button on the keypad
or remote control were pressed. Most commands require both a down and an up key
press.
The type Key Toggle will take 60 ms.
Note: There is a chance for command conflict if DisableUserEntry is not active,
particularly from stray IR remote control signals.

6 Remote Control
6.1 Introduction
There are two universal remotes designed by UEI for use with the D10 and H10 STBs. One is
the standard IR universal remote, model RC 23, which comes with each D10. The D10 only
accepts IR commands. The other is the IR/RF universal remote, model RC24, which comes with
the H10. The H10 accepts both IR and RF signals. Both remotes look the same as shown in
Figure 5 with the exception of the FORMAT key which is only found on the RC24.
The following sections list the DIRECTV remote control key codes for IR emitters used to
control the STB. Also included are the brand setup code list used for setting up the remote to
control the TV and auxiliary devices. It is the same code list found within the STB user
interface.
