Page 4: Nova Helix
1. Nova Helix The operation manual describes the operation of the Nova Helix receivers. • The Nova Helix functionality allows for both “Master” learning and “Link” learning • Multichannel receivers support up to 15 unique output channels (SmartSwitch II devices act as the additional physical outputs) •... -

It is possible, and desirable in some cases, to disable the simultaneous channel activation feature. To effect this, the multichannel receiver must be powered up with a special combination of jumpers fitted. page 6 www.centsys.com...

9. If no additional buttons are pressed within the 10s learning period, the receiver will automatically exit learn mode. This exit is signalled by an extended single beep. The Status LED also switches off and resumes its responsibilities in normal mode. www.centsys.com page 11... -
Page 12: Demastering Buttons
3.3. Demastering Buttons When a Nova Helix system is commissioned, all buttons learnt into the receiver are granted master privileges for that receiver. From a security perspective, this is not always desirable. To overcome this potential security issue, the system has the ability to ‘demaster’ master buttons. -
Page 13: Deleting Buttons
2 through 7. Remember, the system must remain in demastering mode to delete buttons. 9. If no additional buttons are pressed within the 10s demastering period, the receiver will automatically exit demaster mode. This exit is signalled by an extended single beep. The Status LED also stops flashing and resumes its responsibilities in normal mode. www.centsys.com page 13... -

3. Press a new button to learn it into the system. As with master learn mode, the system learns a new button on the trailing edge (i.e. ‘ trailing edge learning ’) of the transmitter transaction. 4. The leading edge of the transmitter transaction is acknowledged with a short beep. This beep occurs irrespective of whether the button is already learned into memory or not. page 14 www.centsys.com... -
Page 15: Remastering Buttons
(in fact, it will occur irrespective of whether the button is in memory or not). 6. While the demastered button is held down, the LED will flash (64ms on/448ms off) to register that the button transmission is being received, and that the button is a demastered button. (Refer to Appendix A on page 30 for a description of the LED and buzzer feedback). www.centsys.com page 15... -
Page 16: Master Learn Remastering
Since all remotes that are added to a receiver are always added with master privileges, a mechanism has been exposed on the Nova Helix receivers that allows certain groups of remotes, currently learnt on the receiver, to be demastered simultaneously. -
Page 17: Autolearn Mode
The selected channel (set via the channel jumpers) is not blank, or no channel has been selected (no channel links fitted). In this case the system enters bulk demaster mode. Refer to the section with the title, Bulk Demastering, for more information on the behaviour of the system in this mode. www.centsys.com page 17... -
Page 18: Link Erase Mode
The procedure to perform the erase operation is documented below: 1. Start with the receiver powered up 2. If a particular channel compartment must be erased (in other words, if all the remote buttons associated with a particular channel must be erased), then fit the channel jumpers that select the desired channel. page 18 www.centsys.com... - Page 19 • Clears non-volatile latch state for all channels • Clears all primary channel relay outputs • Sets the receiver’s special feature settings back to their defaults TABLE 5.

This is a new feature associated with the Nova Helix receivers and is referred to as the Sticky Latch feature. It can be disabled if required on multi-channel receiver variants. Sticky latches provide a fault-tolerant and secure remote control system. - Page 23 10. If the link across jumper J2 is not removed after a period of 240 seconds, the LED will stay on permanently. If the jumper is removed after this, the receiver will set the maximum pulse time-period of 240s. 11. The buzzer will beep briefly when the link is removed to confirm that the new time has been saved. 12. The receiver will now exit channel configuration mode, transitioning to normal mode of operation. If additional receiver outputs must be configured, the above steps must be repeated for the relevant output. www.centsys.com page 23...

Page 24: Simultaneous Primary Channel Activation
5.2. Simultaneous Primary Channel Activation The Nova Helix multichannel receivers provide the facility to activate their primary channels simultaneously. This facility combined with the ability to configure each of the outputs' settings independently allows for intelligent output activation. For example, on a two-channel receiver, channels 1 and 2 can be activated simultaneously by a single button. Channel 1 can be configured to provide a brief 300ms pulse, while channel 2... - Page 25 SmartSwitch II device is sent a command to clear its output state TABLE 13.

Page 28: Smartswitch Ii Interface Capability
8. SmartSwitch II Interface Capability The Nova Helix multichannel receiver provides an interface to connect SmartSwitch II (SS II) devices to the receiver. The interface requires a common ground connection, and one signal wire. The receiver sends all the information relevant to the SmartSwitch II device over the signal wire. - Page 29 Having said that, it is recommended that the power connections use at least two conductors in parallel when wiring up the SmartSwitch II network. This will ensure the bus voltage remains stable, regardless of the current drawn over the network. www.centsys.com page 29...
