DESCRIPTION |
| |
|
|
|
| |
 |
High Power 5 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. |

Standard 5 Channel
Receiver - Mk 1 |
|
| |
|
|
|
| |
|
The Mk
1 Receiver is designed
to receive microwave signals from the Transmitter and display high
quality pictures and sound on any monitor of your choice, as before. It
is compact and light with an efficient omni-directional aerial
a right angled SMA connector comes as standard.
You
can expect up to 300 metres range outdoors (line of sight) or up to
30 metres indoors. However, in this case, with The Stamp the
ranges you can expect are 50 or 15 metres respectively.
The Receiver can be powered from any nominal 12 volt source capable
of supplying 170mA. The actual voltage range is from 8 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 5 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 on the unit with the new mini toggle power
switch and check the green LED comes on.
The aerial is our new, rigid screw-on type with an
SMA connector. (This allows much greater choice of
aerial options - such as the 8dB High Gain Box Aerial). |

|
|
Standard 5 Channel
Receiver - Mk 1 |
|
| |
|
|
|
| |
|
Video is output via the BNC socket and sound via the
3.5mm stereo jack socket.
If you have a multi-channel unit
make sure the rotary selector switch to ensure the Receiver is set
to the same channel as the Transmitter.
Switch on the unit 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.
We can supply suitable batteries, mains power pack and cables if
required.
Make sure the aerial is vertical and clear of any
surrounding metalwork or obstructions.

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. |
|
| |
|
| |
|
|
Note that only channels 1 to
5 on the channel selector are valid. |
|
| |
|
| |
|
|
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 with the standard Transmitter outside
line of sight these problems largely don't arise and the signal is
much more stable. When used with the standard Transmitter 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. |
