PRODUCT DESCRIPTION
• DCT2RTS gateway: Provides communication between third party home automation
systems and RTS motors through simple dry contact input interface.
1.2 RTS commissioning
Before using the DCT2RTS interface, we recommend programming each motor in
advance using an individual Somfy remote control (e.g. Situo) and set the limit
positions of each motor.
1.2.1 Procedure
1. Select the channel of the motor on the existing remote control, hold the
program button on the remote for 3 seconds, for the motor to jog
2. Select the desired channel (channel 1 – channel 5) via the RTS channel selector.
3. Press and hold the RTS PROG button for 1 second.
4. RTS motor jogs; the motor is now programmed to DCT2RTS gateway.
5. Repeat the same procedure to remove a motor from the DCT2RTS gateway.
1.2.2 RTS motors functional test
1. Select the channel via the RTS channel selector.
2. Press the UP/DOWN button on DCT2RTS interface to control RTS motors.
3. The motor jogs to indicate the connection is successfully established. If the
motor does not respond to the command, it means the establishment failed.
Repeat 1.2.1 Procedure, Steps 1-4 again. Alternately it may simply mean
that the RTS motor has been removed.
1.3 Operation
1. To activate an UP command, a minimum of 0.5 second closure is required
between the UP and COM terminals (5VDC). The status LED turns blue to
indicate that RTS signal is sent.
2. To activate a DOWN command, a minimum of 0.5 second closure is required
between the DOWN and COM terminals (5VDC). The status LED turns blue to
indicate that RTS signal is sent.
3. To activate a STOP command, a closure is required between UP, DOWN and
CMD terminals.
Attention:
Press and hold the RTS_PROG button for 5 seconds, the concerned RTS motor will enter to RTS
programming mode.

1.1 Installation
1.1.1 Disconnect the power
1.1.2 Select which type of switch will be connected (fig.1)
1.1.3 Wire either switches (fig.2) or dry-contact relay outputs (fig.3) to the indicated
DCT terminals at the bottom of the DCT2RTS Interface.
1.1.4 Connect the power. The status LED will turn green to indicate the device is
operating.

5. TIPS AND RECOMMENDATION FOR DCT2RTS interface
• The DCT2RTS interface requires 12-24VDC power. The power cable is connected
to the power terminal (item I) using the screw to fix it.
• To improve the RTS radio range, we recommend the DCT2RTS be placed in an
unconfined place in the middle of the house (avoid metallic surfaces and
enclosures).
• In momentary switch mode, only press one button at a time.
• Tilting motion only apply on 1 channel at one time via DCT interface
• The DCT input must have at least 1.5 second suspension in between successive
RTS commands.
• All DCT input port cannot be connected (short circuit) together. (fig.4)
• Does not support fixed position switch mode and momentary switch mode
simultaneously. See below picture. (fig. 5)
6. CAUTIONS
• Always remove the micro-USB cable horizontally and gently. Incorrect removal
could cause damage to the USB port.
• The output voltage of micro-USB power adaptor cannot exceed 5VDC @500mA
• The interface must be installed securely in a fixed position which allows a steady
and level USB input.
• Do not install the interface in metal cases as it may affect the radio signal
strength.
• Install the device on the fixed mounting, e.g wall.
• Avoid dust and water, which may damage the device.
• The DCT2RTS interface for internal use only.
• Do not disassemble the unit.
7. ENVIRONMENT
Damaged electric products and batteries should not be disposed of with normal
household waste.
Make sure to drop them in specially provided containers or at an authorized
organization that will ensure they are recycled.

3. Switch compatibility table
• Momentary switch (Default mode): It is only on when the button is pressed. As
soon as you release the button, the circuit is opened.
• Fixed position switch: An on/off switch that rocks when pressed, which means one
side of the switch is raised while the other side is depressed much like a rocking
horse rocking back and forth.
# If button pressed over 5 minutes, STOP command will not send.
* For non-tilt-able blinds, long-pressing UP/DOWN may trigger moving UP/DOWN fitfully
^ For blinds with My Position, short-press UP+DOWN button while the blinds are not moving, the
blinds will go to My Position
