BR Remote Micro L Head User manual

Micro L
Head
Instructions
Ver. 20.1.4
The Micro L Head (µL) can be controlled by any BR Remote controller. These generate
RS485 data which can be connected directly to the Micro L Head or sent via an IP network
with IP adaptors. The RS485 data can be sent up to 1km on a twisted pair cable.
Power for the µL can be up to 35v so very long ranges can be achieved by increasing the
voltage to the remote end. Inside the unit is a 12v regulated supply for the camera so it
doesn’t matter what voltage you send to the µL, the camera will always have 12v.
Both power and RS485 control data are input via the 4pin Lemo connector on the base.
Currently, the cameras supported with control protocols are Marshal (VISCA) and
Dreamchip. The control protocols for these cameras are embedded in the µL and can be
connected to the camera. The camera itself can then be controlled via BR Remote
controllers. The Camera CCU output is RS422 and is on the 7pin Lemo connector.
There are various widths of camera plate available; 40mm, 45mm and 60mm. Choose the
one that best suits the camera you are using.
As standard the µL is weatherproof and can be used outside. This makes a perfect match for
the small weatherproof cameras that are readily available.
There are slipping clutches on both pan and tilt which prevent damage
to the mechanics if it is moved inadvertently during rigging or if it hits
an obstruction during use.
And if you want to hang it upside down –no problem. There are 3x
M4 mounting threads as well as a ¼” camera thread on the base.

Joystick Control
Like all BR Remote heads, there are 10 ‘gears’. Some controllers can select any gear but
others can only select a smaller number of gears. The movement is fully proportional to the
joystick displacement in all gears.
If the ‘turbo’button is enabled on the controller this will set the speed to the fastest gear whilst
the button is held down.
Pre-Set Positions
The µL has the capacity to store up to 64 pre-set positions although some controllers can only
access 4 positions. When first powering the unit on you will need to manually set a ‘Home’
position or storing the positions you need. You can set a ‘Home’position by using a known
picture position from the camera or by driving it to the ends of the pan and tilt travel. Doing
this will enable it to re-call previously stored positions.
Connections
The µL is supplied with a short cable to connect it to a controller. This cable can be simply
extended following this diagram;

4 Pin Lemo input plug –FGG.0B.304.CLAD52Z
Pin 1 = GND (Blue)
Pin 2 = RS485 data A (Green)
Pin 3 = RS485 data B (Yellow)
Pin 4 = Power 12 –35v (Red)
7 Pin Lemo plug for camera power & data - FGG.0B.307.CLAD52Z (not supplied)
Pin 1 = GND (Blue)
Pin 2 = RS422/485 data A TO camera (Green) Also semi-duplex return data.
Pin 3 = RS422/485 data B TO camera (Yellow) also semi-duplex return data.
Pin 4 = Power 12v camera power (Red)
Pin 5 = future use
Pin 6 = future use
Pin 7 = future use
When power is connected the blue LED on the side will flash 3 times whilst the µL is booting up.
After this sequence the LED will indicate 3 states;
Permanently ON = Power applied, data received but not being addressed.
Very Fast Flashing = Being addressed and should respond to commands.
Flashing Very Slowly = Power but no data.

Cable Management
On the pan cover, under the camera plate are two M2.5 threaded holes. These can be used to
attach cable management clips.
Pan & Tilt Clutch Adjustment
Both the pan and the tilt clutches can be adjusted if needed.
To adjust the pan clutch, remove the Pan Cover which is
secured with a single screw. The cover will need to be
prized off as it is sealed with silicone sealant. The
Adjustment nut is on the top of the shaft and locked with
an M3 grub screw. Use a 1.5mm allen key to loosen the
locking screw and tighten the clutch adjustment nut until
to achieve the required clutch movement. It should be
set as lightly as possible without slipping. If it is
adjusted too tightly, damage may occur to the pan motor
gearbox.
Clean all the sealant from the cover and the body and re-apply a very thin layer of silicone
sealant before re-fitting the cover.
The tilt clutch adjuster is accessed by removing the Main Cover.
This has 3 screws. Take care not to damage the sealing
gasket. The Tilt Shaft Support Bearing may be on the shaft, as
in this picture, or may me retained in the main cover. Take care
not to lose this bearing.
The tilt adjustment is an M5 Nylock nut under the bearing on
the tilt shaft. You will need an 8mm spanner.
When re-fitting the cover ensure the gasket is located correctly
and that no wires become trapped between the body and the
cover.

Safety
There are 2 M4 bolts fitted to the base which should be used for a safety bond if the unit is rigged
above head height.
Also on the base is a standard ¼” camera mounting thread and 3x M4 threads. Any of these can
be used for mounting the unit to a suitable platform.

Camera Specific Connections
For Marshall cameras, the table below is correct if a Male connector is
fitted on the camera. ie. if the connector on the camera itself has pins –
like in the picture.
