DESCRIPTION |
| |
|
|
|
| |
 |
High Power 16 Channel Transmitter |
|
| |
|
|
|
| |
|
Our Video Sender is
designed to transmit high quality pictures and sound from a camera
to a monitor using a legal, licence free 2.4 GHz microwave link.
The small, lightweight Transmitter can be easily
attached to the camera's battery with velcro, and takes its power
from the camera battery. The small, efficient omni-directional
aerial radiates in all directions. Make sure the aerial is as
high as possible and proud of the camera body.
The Transmitter is powered with any voltage from 9
to 36 volts via a standard 4 pin Hirose socket. |

|
16 Channel Receiver |
|
| |
|
|
|
| |
|
The Receiver is designed
to receive microwave signals from the Transmitter and display high
quality pictures and sound on any monitor of your choice. it
is compact and light with an efficient omni-directional aerial
attached by a right angled SMA socket.
You
can expect up to 300 metres range outdoors (line of sight) or up to
30 metres indoors, or more with higher gain aerials.
The Receiver is housed in
a robust case and has a rigid screw-on aerial with a right-angled
SMA connector. The Receiver can be
powered from any nominal 12 volt source capable of supplying 170 mA.
The actual voltage range is from 9 to 16 volts and is applied via
the 4 pin Hirose socket on the end of the unit. |

WARNING |
| |
|
|
|
| |
| |
|
|
| |
If powering from a
camera's Hirose socket please make sure your camera can supply
the necessary current without blowing the internal fuse.
If not, use another source such as the BP90 socket on a PAGlock
plate. Current consumption
of the Transmitter is 170mA at 12 volts. The Transmitter
has a switch mode power supply inside so will consume half the
current at 24 volts and pro-rata for other voltages. |

INSTRUCTIONS FOR USE |
| |
|
|
|
| |
|
|
High Power 16 Channel Transmitter |
|
| |
|
|
|
| |
|
Connect the video in to
the BNC socket. The video signal should be PAL or NTSC
composite video at 1 volt p-p.
If sound is
required connect a line level signal to the phono socket.
Select a suitable free channel on the rotary
selector switch, and make sure the Receiver is switched to the same
channel.
Switch the unit on with the new mini-toggle power
switch and check the green LED comes on.
The aerial is our new, rigid screw-on type with
SMA connector. This allows much greater choice of aerial
options, such as the Box Aerial.
If you are using more than one Transmitter you
must leave the maximum space between channels, but the minimum is
one channel (ie use channels 1 + 5, or 1 + 3 + 5, etc, but not
adjacent channels such as 1 + 2 or 2 + 3, etc) |

16 Channel Receiver |
|
| |
|
|
|
| |
|
The Receiver is housed in
a robust plastic case and has a rigid screw-on aerial with a right
angled SMA connector. The Receiver can be
powered from any nominal 12 volt source capable of supplying 170mA.
The actual voltage range is from 9 - 16 volts and is applied via the
4 pin Hirose socket on the end of the unit.
Video in output via the BNC socket and sound is
via the phono socket.
Ensure the rotary channel selector switch is set
to the same channel as the Transmitter.
Swindon on using the toggle power switch on the
end of the unit and check the red light comes on. The
brightness of the light indicates the battery state. As the
battery runs down the light will dim and when it goes out the unit
will stop working and the battery will need recharging.
Make sure the aerial is vertical and clear of any
surrounding metalwork or obstructions.
We can supply suitable batteries, mains power pack
and cables if required. |

PROBLEM SOLVING |
| |
|
|
|
| |
|
|
If you experience
interference or bad picture break-up try another channel, as it is
likely there is another unit on the same frequency. Don't
forget, the Transmitter and the Receiver must be on the same
channel. As mentioned already mentioned above, please
check our
Frequency Chart
(or the
TX/RX Specifications Comparison)
for more information. |

|
| |
|
|
The Transmitter
has an omni-directional aerial which radiates in all directions.
It is very important that the aerial tip is free of space with no
objects or wires near it. |
|
| |
|
| |
|
|
When using the Sender indoors reflections from
girders, wiring, etc, will cause occasional flashes on the received
picture when cancellation occurs. This will only happen when
the Transmitter or Receiver is moving relative to each other or when
objects are moved between the Transmitter or Receiver. |
|
| |
|
| |
|
|
When used outside line of
sight these problems largely don't arise and the signal is much
more stable. Using the standard omni-direction aerials, a
maximum range of about 300 metres should be obtained outside,
line of sight. Indoors a range of around 30 metres should
generally be expected. Using higher gain aerials will
obviously provide extended ranges. |
