Use of the combination IVS RFI and RFII
As you know it is possible with the IVS system to use different versions of the keypads for one session. However, we do advise to keep both types "together". If you want to use the combination of RFI and RFII keypads we recommend that you first initialize all RFI keypads and then the RFII keypads. Should you initialize the keypads completely mixed it can influence the network.

Can I change the communication channel?
You can change the channel before initializing the keypads. If you already initialised the keypads, you CANNOT change the channel. The keypads are active on the selected channel. If you change the channel the keypads can not be used during the session.

Can I use more than one Clustercontroller?
You can use more than one clustercontroller. The number of clustercontrollers you can use depends on the number of serial ports in your computer. If you want to use more Base Stations (clustercontroller for the RF version) you must select a channel for each Base Station.

Why is it so important to save a list with keypads?
It is recommended that you always save a list with keypads. You can use a list with keypads to restore the communication. If the power fails during a session, you can activate the keypads again by using the list.

How do the keypads and the Base Station communicate?
The keypads communicate with the Base Station by using radio signals. Both keypads and Base Station have a receiver and a transmitter which they use to communicate.
