Multicore
- via XLR4
All our equipment is supplied as standard with a 4 pin output or
input plug. Where space permits this is an XLR4. Where there is
no space for an XLR4 we will use either a 4pin Hirose or a Fischer
102 series DBEE. In general the Fischer socket is used for IP67
integrity.
All 4 pins are used to transmit both Power and data down the same 4 core cable. Pinout details are available as a PDF file on the technical specifications page.
Modulated
Video Circuit
Data can also be modulated onto a 75 ohm video circuit. One example of this being useful is when using a remote head on a Triax system. the data can be sent via the return video channel (not required when there is no cameraman). Data is ASK modulated onto a 100kHz carrier.
Radio
Data Transmission
Data can also be sent via our radio data transmitters. These are
available in a variety of frequencies and power outputs. Usually
we supply them on license free bands but this may vary depending
on the regional regulations. Simply plug the controller into the
transmitter and all the controls become available wirelessly.
Most of our remote heads can be fitted with internal radio data
receivers.
Digital multiplex system for Power, Data, Genlock and SDI Video
The Rx-Mk3 is a sophisticated digital data receiver which can control many 3rd party remote heads and control most lenses. Camera control protocols can also be embedded to enable easy camera control.
We
can also supply assembled PCBs for driving Pan & Tilt servos.
Bradley Engineering manufactures suitable data transmitters and receivers.
All the code balancing and error correction is taken care of within the
transmitters and receivers. They are generally set up to operate on the
licence free band and offer 32 selectable channels. They are powerful
units (500mW) and can be used for 3rd party data as well. The receivers
can also provide camera power and control data. This may be required if
you are not using a Bradley Engineering Pan & Tilt head.
