PRODUCT DESCRIPTION

• DCT2RTS gateway: Provides communication between third party home automation
systems and RTS motors through simple dry contact input interface.

• Z-Wave2RTS interface: Z-Wave enabled device (interoperable, two-way RF mesh
networking technology) that is fully compatible with any Z-Wave enabled network.
Receives Z-Wave signals and translates them into RTS commands to allow control
of Somfy RTS enabled motors.

The Z-Wave2RTS interface supports mulit-channel Command Class for up to 8

devices corresponding to control of up to 8 individual or 8 groups of Somfy motorized
products.

Z-Wave enabled device acts as a signal repeater and multiple devices result in more

possible transmission routes which helps eliminate “RF dead-spots”.

Z-Wave enabled device displaying the Z-Wave logo can also be used with it

regardless of the manufacturer, and ours can also be used in other manufacturer’s
Z-Wave enabled networks.

1.2 RTS commissioning

Before using the DCT2RTS interface, we recommend programming each motor in
advance using an individual Somfy remote control (e.g. Telis) 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.

2. Z-Wave2RTS interface setting

2.1 Installation

2.1.1 Disconnect the power (fig.4)

2.1.2 Locate the Z-Wave2RTS interface within direct range of the Z-Wave HUB.

2.1.3 Select the “appropriate channel number” on the RTS channel selector.

2.1.4 Connect the power. The status LED will turn green to indicate the device is operating.

2.1.5 The Z-WAVE LED will blink to indicate Z-WAVE2RTS interface is opened to add
to Z-WAVE network.

!! The channel number selected should reflect the number of RTS channels being applied on
Z-Wave Hub, for example, if 3 channels will be used, then select number 3 on the RTS channel
selector before powering on the Z-WAVE2RTS interface.

2.2 RTS commissioning

Z-Wave2RTS interface supports RTS channel 1 to channel 8. For details, please refer
to section 1.2.

2.3 Z-Wave network commissioning

2.3.1 Inclusion (Add Z-Wave2RTS interface to Z-Wave Hub)

1. Enable the Z-Wave HUB into the Inclusion mode.

2. Short press the Z-Wave PROG button for 3 times. Z-Wave2RTS interface will

be added in the Z-Wave network automatically.

3. The Z-WAVE LED turns OFF indicating that the Z-Wave2RTS interface has

successfully added the Z-Wave network.

2.3.2 Exclusion (Remove Z-Wave2RTS interface from Z-Wave Hub)

1. Power ON the Z-Wave2RTS interface.

2. Enable the Z-Wave HUB into exclusion mode.

3. Short press the Z-Wave PROG button for 3 times.

4. The Z-WAVE LED blinks indicating that the Z-Wave2RTS interface has

successfully been removed from the Z-Wave network.

2.3.3 Reset the Z-Wave module to factory mode

Please use this procedure only in the event that your network primary

controller is missing or otherwise inoperable.

3. Power ON the Z-Wave2RTS interface and wait for 10 seconds.

4. The Z-Wave LED blinks indicating that the data is cleared and it is opened to

add to Z-Wave network.

Tips: How the endpoint is used by the Z-Wave2RTS interface?
Z-Wave2RTS interface supports Z-Wave multi-channels command class. Each
endpoint represents each RTS channel. For example, endpoint no.1 equal to RTS
channel no.1, endpoint no.2 equal to RTS channel no.2 and etc. All End Points have
the same Generic and Specific Device Class and Optional Command Classes.

Generic Device Class : GENERIC_TYPE_SWITCH_MULTILEVEL
Specific Device Class : SPECIFIC_TYPE_CLASS_A_MOTOR_CONTROL
Supported Command Classes : COMMAND_CLASS_ZWAVEPLUS_INFO,

COMMAND_CLASS_ASSOCIATION_GRP_INFO,
COMMAND_CLASS_ASSOCIATION_V2,

7. 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.5)

• Does not support fixed position switch mode and momentary switch mode

simultaneously. See below picture. (fig. 6)

8. TIPS AND RECOMMENDATION FOR Z-Wave2RTS interface

• Before power ON the device, please set the maximum number of RTS channels on

RTS channel selector (item G)

• The Z-Wave2RTS interface requires 12-24VDC power. The power cable is

connected to the power terminal (item I) using the screw to fix it. As an alternative,
power can be supplied through the 5VDC Micro-SUB if the proper adapter is used.

• Supply powers either 12-24VDC or 5VDC micro-USB input port. The device cannot

be operated by both power inputs together.

9. 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 and Z-WAVE2RTS interface are for internal use only.

• Do not disassemble the unit.

10. 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.

6. Technical specification

5. 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.
^ Other option: Press then release UP and DOWN together (~1 sec)
* Each tilting increment is by 0.5 sec/step.
