CP JR Remote Head

Operations Manual

BEFORE YOU START, READ THESE WARNINGS

1) ONLY USE VARIZOOM POWER SOURCES AND CABLES. USING DIFFERENT

POWER COMPONENTS CAN LEAD TO SEVERE DAMAGE TO THE HEAD AND

EVEN THE CAMERA. THIS TYPE OF DAMAGE IS NOT COVERED UNDER

WARRANTY.

2) TURN OFF POWER WHEN NOT IN USE. DO NOT LEAVE STATIONARY HEAD

POWERED UP FOR EXTENDED PERIODS OR THE MOTORS MAY SEIZE AND

THIS IS NOT COVERED BY WARRANTY

3) ALWAYS BALANCE THE CAMERA ON THE PLATFORM BOTH HORIZONTALLY

AND VERTICALLY.

4) DO NOT MODIFY THE SUPPLIED CABLES OR ATTEMPT TO DISASSEMBLE THE

HEAD.

5) LENS CONTROL CABLES MUST ONLY BE PLUGGED INTO THE SPECIFIED

INPUT JACK ON THE LENS ITSELF –NEVER PLUG A 12-PIN CONNECTOR ON A

VARIZOOM LENS CONTROL CABLE INTO THE 12PIN JACK ON THE CAMERA

BODY. WHEN IN DOUBT, CONSULT VARIZOOM OR YOUR LENS MANUAL.

6) DO NOT GET THE SYSTEM WET –IT IS NOT WATERPROOF.

7) ALWAYS MAKE SURE YOUR LENS AND POWER CABLES HAVE ENOUGH

SLACK RUNNING THROUGH THE TILT AXIS TO PREVENT TWISTING AND

TEARING OF THE CABLES.

8) MAKE SURE YOUR LENS CLEARS THE BASE OF THE HEAD WHEN TILTING. IF

THE LENS DOES NOT CLEAR THE BASE, SET SOFT LIMITS (SECTION 7) TO

PREVENT THE LENS FROM STRIKING THE BASE OF THE HEAD WHEN

TILTING.

9) WHEN USING THE CP JR’s ONBOARD LENS CONTROLS TO CONTROL YOUR

CAMERA, ALWAYS POWER THE CAMERA UP LAST. OTHERWISE, THE

RECORD START/STOP FEATURE MAY FALL OUT OF SYNC. TO AVOID THIS

ISSUE, JUST MAKE SURE TO CONNECT XLR POWER TO THE HEAD BEFORE

YOU TURN YOUR CAMERA ON.

General Description

The CinemaPro JR is a lightweight, two-axis motion control head with lens interface controls for zoom

and focus. It handles several control signals: RS-232 for Fujinon digital lenses or Varizoom (TOC) motor

drives, RS-422 for Canon digital lenses or Preston motor drives, analog control for Fujinon or Canon.

1. Basic Setup

-Secure the head to crane, tripod, or solid mounting beam

-Plug the FACTORY POWER SUPPLY into AC mains

-Connect XLR cable between head and FACTORY POWER SUPPLY

-If present, plug the zoom/focus hand unit into the Jibstick Pro, THEN plug

the green control cable into the green 7pin port on the Jibstick Pro

-If applicable, connect camera power (red) and lens control cables (orange)

and route the cables through the tilt axis port hole to connect to your

camera

-Make sure to turn camera power on as the LAST step.

Feeding External Cables through the Head

In some cases, you will need to feed video or other cables

through the head. To do so, simply remove the cable covers

(pictured at right, covers may differ slightly in appearance).

4 screws secure the long vertical cable cover (we have

eliminated the small horizontal cover on newer models).

Run the cables through the pan base and tilt arm with

enough slack, and reattach the cable cover.

If using the TOC system

Connect the TOC 3A (3 axis lens drive box) between the

orange 16-PIN lens control connector located on the head,

and the grey “control” connector located on the TOC 3A.

Connect the Lens drive motors to the appropriate connection

according to their function (zoom, focus, iris)

Balance the Camera –Although the head will hold position very well, it operates best when the camera

is balanced on the mounting platform. With heavier cameras, it is essential, as an out-of-balance load

will cause the servos to constantly fight to hold position. Make sure that the motor power is turned off

before balancing. This will allow you to move the tilt axis by hand. To balance the camera

horizontally, you need to place the camera’s front-to-back center of mass at the center of the mounting

platform slot. You can do this by trial and error, sliding the camera front-to-back on the mounting

platform until it stays level. The simplest accurate way to find the camera’s center of mass is to lay a

pencil/pen on a table and try to balance the camera on it front-to-back. The spot on the camera where

it comes closest to balancing on the pencil is the center of mass. Place the camera’s center of mass at

the center of the mounting slot and secure the camera with mounting screws (2 if possible). When

horizontally balanced, the platform should stay level.

To get the vertical balance right, raise or lower the platform to get the

camera’s vertical center of mass located on the center of tilt rotation. To

adjust, loosen the platform locking lever about ½ turn. Turn the black knob

on the underside of the platform to precisely raise or lower it –you can use

a hex key. Try to get the camera’s center of mass right on the center of tilt

rotation. Rotate the platform to various angles and adjust until it holds

position at any angle. If it falls down, you need to adjust the platform

upward. If it drifts upward, you need to lower the platform. When balance

is achieved, tighten the platform locking lever.

After all connections have been made and the camera is balanced, the head is

ready to be powered up.

Connect the power supply to AC power. Plug in the green communication

connector to the head, and the other end to the jibstick. The jibstick should

now power up. Once the Sync light is illuminated, you may then turn on the

motor power switch.

3. Troubleshooting

No Response from head

1) Make sure that the motor power switch is turned on and the light above it is green.

2) Check to make sure soft limits aren’t set too close together. Disable all soft limits and try again.

3) Power down the system for 20 seconds and start it back up.

Head is “jerky” or too responsive

1) Turn down motor speed.

My jib or crane sways, swims, moves around when the head is rotating

1) This is a problem of imbalance in rotational inertia. If the jib moves when panning, you need to

attach the optional counterweight. If the jib moves around when tilting, you need to adjust the

vertical balance (adjust the camera platform until the camera’s center of gravity is on the center

of tilt rotation.

Head moves on its own

Cycle power and do not touch the joystick when powering up the system. The joystick has to calibrate

on power-up, so if it’s off-center then it will calibrate incorrectly.

4. Options and Specs

Additional Head options-

The Head can be fitted with either a 100mm half ball or Mitchell mount. A Mitchell ring adapter is

available for old style Mitchell mount.

An adapter is also available to adapt Mitchell mount to Jimmy Jib style mount.

Wireless control is available, and operates up to ¼ mile. (1 mile with line of sight).

Additional controller cables are available in 50’, 100’, or 150’ increments. A coupler is available to join

the cables, or we will make a cable of any reasonable length as a custom item on request.

Head XLR power cables are available in standard 30’ or 75’ increments, or longer as a custom item on

request.

Jib Counterweight Option

Some lightweight jibs may not have enough mass to neutralize the high acceleration and torque of the

CP Jr head. If the motion of the head causes your jib to sway from side to side in a way you want to

eliminate, we have a counterweight option that will effectively eliminate the problem.

Heavier jibs will not be affected much, and the effect is only significant during sudden moves. Adding

our counterweight to the CP Jr balances out the rotational inertia so even lightweight jibs will not be

susceptible to the swaying effect caused by sudden moves.

Attaching the counterweight is simple. Before

attaching the counterweight, fix the head to your

jib.

(1) Start by attaching the interface plate to the

head with the 4 small screws (supplied). Now fix

the support arm to the interface plate using the

supplied thumbscrews, lockwashers, and flat

washers. Put the flat washers between the

support arm and the lockwashers to prevent

scratching. Tighten the thumbscrews thoroughly.

(2) Now attach the square weight to the support arm,

using the same type of thumbscrews, lockwashers and

washers. Tighten the thumbscrews thoroughly.

The counterweight adds about 7 lbs total weight to the

system, so if you don’t need it, try operating without it

first. Also note that some swaying may be caused by the

camera platform being out of vertical balance –remedy

this by adjusting the camera platform up or down so the

camera’s center of mass is on the center of tilt rotation.
