7. Setting up your Nova Transmitter for Operation
7.1 Coder
7.1.1 Address
The coder address with which the NOVA transmitter has been programmed from the factory can be found listed on the
datasheet. This can be updated via Hetronic PC-Link in the ‘RF’ tab and any number between 1 and 999999 can be used (refer
to Service and Programming Manual for instructions).
7.2 Communication
7.2.1 Radio Settings
The NOVA coder is designed with the possibility to connect two on board RF modules either operating in the sub 1GHz range
as well as 2.4GHz. When the RF module is plugged directly on to the coder (onboard), the user may select the frequency
channel or group to use for communication. If the RF module is connected to the coder externally (through a cable set inside
the transmitter) the channel will depend on the SIP switch settings as outlined in the RF module and Frequency Bands charts.
The RF module is used for either transmitting only the control telegram or else operating in half duplex mode. For the coder to
operate in full duplex mode then a second RF module has to be connected and configured using Hetronic PC-Link (refer to
Service and Programming Manual for instructions).
7.2.2 Auto-OFF
A transmitter Auto-OFF timer can also be set which powers down the coder if it remains idle for a configured period of time. The
Auto-OFF timer can also be disabled so that the coder remains always ON until either switched OFF manually or else when the
critical battery voltage level is reached and thus the transmitter switches off automatically (refer to Service and Programming
Manual for instructions).
Note: In the case of Nova-S transmitters, a jumper setting on the coder determines whether the transmitter switches off or not
after 10 minutes of inactivity.
7.2.3 Radio Mode vs Cable Control Mode
Detection of the presence of Cable Control supply can be set automatically to switch to Cable Control mode. In Cable Control
mode, the telegram will be sent through the cable RS232/CAN and the Radio mode will be OFF.
Cable Control detection can also be disabled. In this case, the Radio mode will always be used. This is useful whenever the
remote control is required to work in Radio mode and the available voltage supply is between 5 and 30V, thus must be supplied
via the cable control connector.
The presence of Cable Control supply can also be used as signal to activate a C12HL output.
7.3 DK Configuration
There are 32DK switch assignments on the coder board and an additional 48DK switches can be used when an optional
expansion board is added to the system. The 80DK switches have fixed assignments corresponding to DK1 to DK80 and
cannot be modified. The final status of the telegram DKs is dependent on the Hetronic PC-Link configuration which is a logic
combination of Input Signal/s and its corresponding DK switch for telegram DK1-DK32 and selected Input Signal or DK switch
for telegram DK33-DK80.
7.4 AK Configuration
There are 16 configurable AK channels (AK1 to AK16). Each AK channel can be independently assigned to a particular Signal.
When no Signal is configured to the AK, the corresponding AK channel will remain in neutral position. The neutral position can
be 0x7F or 0x00 hex value corresponding to the Type selected which is Uref/2 or 0-Uref respectively. The AK Channel signals
can be either set as Analog Inputs or Gray Code or ADC configurations, in which the analog inputs are used to generate digital
step or gray code signals that can be used to trigger telegram DKs. Refer to Service and Programming Manual for instructions.
7.5 Digital Outputs
The coder has 25 configurable outputs which include the Buzzer, two open collector outputs, six push pull digital outputs (TTL1
to TTL6) and 16 optional outputs (LED1 to LED16) when an additional expansion board is used. All the outputs can be
assigned with DK signals, feedback bits, logic gates and any coder status signals available. The output active state can be set
as either continuous or pulsing with adjustable On/Off durations.
All outputs can be configured latching, thus it will remain active once the signal is activated and remains active even after the
signal is deactivated. The latched output turns OFF after the signal is reactivated. The latching function can also be set to
switch OFF once the Stop function is activated. Refer to Service and Programming Manual for instructions.
