DESCRIPTION |
| |
|
|
|
| |
This system is designed
to transmit time code from a camera to a recorder using a reliable
and robust UHF link, operating on 434.075 MHz. |
| |
|
|
|
| |
 |
A small, light Receiver module (built into a
diecast box), powered by an MN1604 with long battery life, or via
a 4 pin Hirose socket (with automatic switching) |
|
| |
|
|
Sunlight-visible batter indicator
blue LED |
|
| |
|
|
Sunlight-visible "carrier being detected"
red LED |
|
| |
|
|
Data output on BNC socket on the side of the
unit |
|
| |
|
|
Virtually immune to interference from nearby
frequencies (such as TETRA, cranes, etc) |
|

INSTRUCTIONS
FOR USE |
| |
|
|
|
| |
|
|
Connect the supplied aerial to the top BNC socket
on the Receiver and connect the time code output to the BNC
socket on the other side of the Receiver. This applies to
either the Standard Self Powered Receiver,
or the Miniature Receiver, or even
the Radio Time Code Reader. |
|
| |
|
|
| |
|
|
Switch on the Receiver with the top mounted
toggle switch and the blue LED should
light showing the unit is on and the battery is OK. The LED
should light bright blue - if it is
dim or out replace the MN1603/PP3 battery by sliding it out from
the battery box. The Receiver can also be powered from the
Hirose socket on the side of the unit
|
|
| |
|
| |
|
|
Connect an aerial to the Transmitter's BNC socket
on top of the blue anodised case. Connect a BNC lead from
camera Time Code out to the input BNC (male) socket on the
Transmitter. |
|
| |
|
| |
|
|
Connect a 4 pin Hirose lead from the 12 Volt
power out on the camera to one of the Hirose sockets on the
Transmitter (the two sockets are identical, and either one can
be used for either power in or power out). The
blue LED on
the Transmitter should light brightly. |
|
| |
|
| |
|
|
Mount the Transmitter wherever convenient (using
the supplied Velcro strips if necessary). |
|
| |
|
| |
|
|
The red carrier detect LED on the Receiver should
now be lit showing that that the Transmitter's carrier is being
detected and that the Receiver is in range. The brightness
of the red LED gives an indication of received signal strength.
The unit may still work even with the red LED out, but you would
be right up against the maximum range. |

|
Receiver Battery Life |
|
| |
|
|
|
| |
|
The Receiver battery is
usable down to 6.5V at which point the blue
battery indicator LED will have gone out. As a rough guide the
LED is bright at 9V, medium at 8V, dim at 7V and out at 6.5V.
Current consumption is about 20mA so expect around 30
hours from an MN1604 or 100 hours from an UltraLife. |
| |
|
|
|
| |
|
|
Time Code Output Level |
|
| |
|
|
|
| |
|
The time code output
level from the Receiver is set at 2.2V peak to peak which will suit
most applications, but this is adjustable internally from 0V to 4.5V
by the horizontally mounted blue
pre-set 2.2k trimmer near the battery compartment. |

|
Aerials |
|
| |
|
|
|
| |
|
A stubby UHF aerial is
supplied with each unit. Additional long and short aerials are
available at £20 each. |
