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.

2 Set-top box Front Panel Shortcut Keys
The following shortcut key combinations are implemented by pressing the front panel keys
simultaneously. The shortcut keys may not work if user interface graphics are on the screen
instead of video. Table 2 shows which shortcut keys are supported by each model.
Table 1: Shortcut Keys Combinations
Key Combination Action
ACTIVE and UP Access the System Setup: System Info & Test screen.
ACTIVE and RIGHT
Access the System Setup: System Diagnostic (hidden) screens.
The System Diagnostic screen contains menu items to change the LNB
configuration to stacked/unstacked; input phone settings for prefixes
and call waiting, and a modem test.
ACTIVE and DOWN
Skip Guided Setup and display Startup: Full Screen (Live TV) on the
default channel

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 L5-
Grnd) 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.

Version 1.1.a Page 10 of 49 DTV-MD-0058
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.
Table 4: Timing Characteristics
Parameter Requirement
Bit Timing 104 µs ±7 µs
Total Character Interval 1.04 ms ±8 µs
3.4 Bit Timing (Start, –D0 TO –D7, and Stop)
The STB complies with the bit timing requirements as shown in
Figure 3.
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.”
Total Character Interval
Start Bit 8 Data Bits
D0 D7 Idle
Stop Bit
