Setting
Description
Dual Pedestal
Specifies whether you want to use a double-capacity wireless link.
‘Single Stream’ creates a single video link with double capacity.
‘Dual Stream’ creates two independent video streams.
In
‘BSI control’ mode, the selected setting syncs with the transmitter.
Bandwidth
Defines the bandwidth of the RF transmission.
In
‘BSI control’ mode, the selected value updates the camera back
transmitter. If the bandwidth is not correct, the system will still work if
under
‘BSI control’, but if not, you will need to match the value to the
transmit parameters.
ASI Input
Defines which rear panel RF inputs are diversified with the rear panel ASI
input.
This is always RF1
–8, unless you have selected ‘Dual Stream’ mode,
where you can select which set of RF inputs are diversified with the ASI
input.
Remote transmitter control settings
You need to set the frequency that the camera back transmitter will use to transmit the video stream. You
should also check the other settings, adjust the transit power, and ensure that the camera video format is
correct for the production.
From the main menu, select
Remote Tx Crtl
and configure as follows.

Description
Remote Transmitter
Defines whether RF is switch on or off. ‘Power On’ is the operating state.
Select ‘Standby’ when the system is not required (RF turned off) and you
want to save power, for diagnostics or to re-boot a POV camera
connected to the transmitter.
Remote Tx Frequency
Sets the transmit frequency assigned for your event.
Update Receive Frequency
When selected, keeps the receive and transmit frequency at the same
value. If you change the transmit frequency, the receive frequency
automatically changes to the same value.
It is recommended that you link these parameters, but during diagnostic
testing you might want to not change the transmitter frequency but change
the receive frequency setting to look at another camera.
Remote Tx Transmit Power
Defines the transmit output power. Start with the lowest power output and
increase only if the Received Signal Strength Indicator (RSSI) is low. If the
power is set too high for your application, you will see a reduction in
Carrier to Noise Ratio (CNR) as the downconverters become overloaded.
You can view the RSSI and CNR on the
For most applications 100 mW is the recommended setting. Optimal
receive strength is between -50 dB and -20 dB.
If you set the value too high, you could overload the system in certain
situations. If the power is too low, the camera range may be insufficient
resulting in loss of RF signal and video image.
Remote Tx Modulation
Sets the robustness of the wireless link and the quality of the video image.
Choosing the wrong values impacts the range of the wireless link and
quality of the video image.
16QAM, 3/4, 1/32 is a good starting point.
