The Network is RS485, half-duplex, bi-directional. The SDN consists of the following components: ILT2 & ST-30 RS485 Motors SDN Switches (3 and 6-button) ILT2 Tap Bus Power Supply ILT2 Motor Configuration Software SDN Switch Configuration Software Standard Cat 5 Cable and splitters RJ9 to RJ11/12 converter and RJ12 modular cable Optional Accessories.

3 IR Transmitter for SDN Switch Local Switch Local RTS Receiver Bus line RTS Receiver Local IR receiver and Transmitter IP Interface RS485 Segment Bridge ILT2 Motor The ILT2 motor has a m power cable with a NEMA 15-5 molded plug and a low voltage RJ9 modular connector in the head of the motor for data. The motor is shipped with a 1 data cable attached. All parameters of the motor, except end limits*, are programmable over the Network as described in section 2. Limits must be set using the ILT switch (#1800410) or the ILT limit setting tool (#9050280).

4 The ILT Address Reader (#9015137) can both read the address of the motor and set limits applies to ILT2 motor only. *End limits can be adjusted via software once initially programmed via limit setting tool. Features of the ILT2 Motor: Unique Address: Each motor is given a unique 3 byte address at the time of manufacture. 16 Intermediate positions: Each motor can store up to 16 preset positions. 16 groups: Each motor can be a member of up to 16 groups. Standard positioning: Includes UP, DOWN and STOP.

5 Relative positioning: The motor can be positioned as a percentage of its travel range ( 50%). SDN INSTRUCTIONS 07/10, Ver SSSooommmfffyyy SSSyyysssttteeemmmsss 4 Precision positioning: The motor can be positioned using encoder pulses. Jog movement: The motor can move in small increments for use in tilting horizontal blinds. Digital text label: The motor supports a 32 character label that can be queried over the Network . Half Duplex bi-directional communication: The motor can be queried for stored parameters.

6 SDN Switches Presently there is a Decora style white 3-button (#1810827) and 6-button (#1810828) SDN switch available. The switches are powered from the Network and draw 10 mA each. There is a power on LED on the back of the switch. The function of each push button is programmable and can have three functions as follows: On Push (activates within 500 ms if On Hold not active) On Hold (activates after seconds if active. In this case On Push is ignored) On Release (activates within 500 ms of release if active) Sequential (press 1: UP, press 2: STOP, press 3: DOWN, press 4: STOP, etc.)

7 Programming the switch is accomplished using the SDN Configuration software as described in section 3. The switch includes an RJ45 connector for Network connection. The SDN switches are IR compatible. In addition there are 8 dry contacts (and common) inputs. Dry contacts must be momentary ( sec) and are mapped to the push buttons. If push button #1 is UP LIMIT, then by default so is dry contact #1. The SDN switches mount in standard single-gang device boxes. 3 - Button Switch 6 - Button Switch Network Connection Dry Contact Inputs.

It requires 12-24 VDC to operate (see section ) which is supplied over the Network . Each Tap draws 7 mA. Each motor attached to a Tap can be controlled individually over the Network . However, local control inputs will activate every motor connected to the Tap as a group.

9 UP/DOWN/COMMON of the low voltage screw terminal is local control. All motors connected to the Tap operate as a group.

10 Typically the power is connected to the first Tap using the screw terminals. Power is then distributed to each Tap over the Cat 5 cable. As an alternative, power can be supplied through the RJ45 on the first Tap if the proper adapter is used. Presently Somfy has available a 12 VDC 1A plug-in transformer (#1822111) and a 24V table top transformer (#1822209). As an option, additional transformers can be installed mid-segment as follows: The maximum current for any one Network segment is 720 mA.
