The control panel is only able to select the Wireless Module Type as either Radion or Inovonics. Therefore only the Radion B810 or the Inovonics B820 can be connected to the SDI2 bus, but not both at the same time.
Note: GV4 panel types must use firmware version 2 and higher for compatibility with the Radion Wireless devices (all B-panels and New G Series panels are compatible with Radion).
However, some existing applications may use Inovonics wireless transmitters with an ISW-D8125CW-V2 connected to the Zonex bus. Because the Inovonics ISW-D8125CW-V2 interfaces with the ZONEX bus and not the SDI2 bus, it can remain connected while adding the B810 Radion Receiver to the SDI2 bus and use Radion transmitters.
NOTE: Ensure that no points are added to the panel program that may already exist in the Inovonics ISW-D8125CW-V2.
