  • X10 XPT Transmitter Base — Installation Manual

    August 31, 2026 4 min read

    Installation manual for the X10 XPT Transmitter Base, a wall-box keypad transmitter that accepts interchangeable X10 keypad covers (XP1, XP2, XP4, etc.).

    Full text manual (for reference)

    Installation instructions for the X10 XPT Transmitter Base — a wall-box-mounted X10 wireless keypad base (transmitter only, does not switch loads) that accepts a variety of plug-on X10 keypad covers for customized room/scene control.

    Overview

    The XPT Transmitter Base mounts in a standard single-gang wall box and accepts an interchangeable Keypad cover, letting each installation be customized to the number of buttons and functions needed. The XPT itself does not switch any loads — it only transmits X10 commands to receiver modules elsewhere in the house.

    Installing the XPT Transmitter Base

    1. In a standard single-gang wall box, connect the Black wire from the XPT Base to 120V AC Live, and the White wire to Neutral, using the included wire nuts.
    2. Make sure no bare wire strands ("whiskers") are exposed; use insulation tape to cover if necessary.
    3. Secure the transmitter to the wall box.
    4. Set the House and Unit Code dials to the desired settings: the red House Code dial should match the receiver modules you want to control; the black Unit Code dial should be set to the first of four sequential commands.

    Note: If controlling only one device (as with an XP1 Keypad), the Unit Code you set is the unit number transmitted. If using an XP4 Keypad, the first command uses the unit number the XPT is set to, and the next three commands use the sequentially following unit numbers.

    Note: The XPT automatically monitors the power line for noise and other signal transmissions and will not transmit until the line is clear.

    Attaching the Keypad Cover

    Place the desired Keypad cover onto the XPT Base by inserting the tab on top of the Keypad under the notch on the XPT Base. Gently press the bottom of the Keypad into place so the pins on the back of the Keypad insert into the XPT Base socket.
