- Page 23 Used frequencies Cross Remote selects the optimal frequency for communication based on the system and the environment. If interference is detected on a currently used frequency, the system automatically switches to another frequency and continues communication. This assures stable operation even under congested 2.4 GHz conditions.
- Page 24 Technology Pairing Prior to being able to use the Cross Remote control functions, the transmitter and receiver must be assigned to each other in a process called pairing. The relationship between transmitter and receiver is that of Coordinator to Device. When NT mode is used, the Remote Control Unit RMU-01 is the Coordinator. Pairing requirement Because Cross Remote uses only three frequencies to control multiple transmitters (up to 82 in NT mode), it is not possible to identify devices by frequency assignment, as for the main communication link.
- Page 25 Roaming In NT mode, when the connection between transmitter and remote control unit is interrupted, the transmitter automatically searches for another remote control unit to connect to. If found, the transmitter connects to that remote control unit, and the connection to the paired receiver is established again.

(thickness), and the subsequent letter indicates the impedance: “C” stands for 75 ohms and “D” for 50 ohms. Both for analog wireless systems and digital wireless systems, Sony recommends “5D-2V” -- “8D-2V” cables with 50-ohm impedance because these have lower transmission losses. 75-ohm BNC cables can also be used. - Page 41 Number of antennas and diversity reception Use two identical antennas The DWX system, like the conventional analog wireless system, uses the space diversity reception principle. Two antennas are employed to receive the signal, with the system automatically switching to the antenna with the stronger signal.
- Page 42 Configuring a DWX System Antenna installation position Distance between transmitter and antenna Line-of-sight service area ranges for different RF power levels are listed below. RF power Transmission distance 10 mW 60 m (196.9 ft.) 1 mW 20 m (65.6 ft.) If the transmitter is located too close to the antenna, input overload may occur, leading to intermodulation distortion and noise.
- Page 43 Booster gain setting conditions BNC cables used with UHF antennas should have low losses. To obtain the proper diversity effect, the cables should in principle be kept as short and large-gauge as possible, and should have the same length. If BNC cables need to be run over long distances, you should use an antenna booster to compensate for cable transmission losses.
