UNPACKING AND INSTALLING THE PT-101 PAN TILT HEAD

Included at the end of this manual is a graphical ﬂ ow chart showing images of the correct manner

of installation. Use it in con junc tion with these writ ten instructions to complete the installation of

the PT-101 system.

Remove the PT-101 head, camera bracket and accessories from the protective foam packaging. It

is recommended to save this packaging until the installation is complete and the head has been

put into operation, in the unlikely event that there is a problem and it needs to be returned for

service.

Choose either the wall/table mounting conﬁ guration, or optional ceiling mount conﬁ guration. If

utilizing the optional PT-WM-S wall mount, make sure that the wall can support a weight of at

least 50 lbs. (or 2.5 times the max. weight of the PT-101 head, camera, lens, and bracket)

If using the optional PT-CM-101 ceiling mount adapter, install the adapter on the base of the head

now using the ac ces so ry kit sup plied with the adapter. Make certain that the ceiling structure can

support a weight of at least 50 lbs. (or 2.5 times the max.weight of the PT-101 head, camera,

lens, and bracket).

Attach the angle mount bracket to the tilt mounting disc on the side of the head. Keep in mind

that if you are ceiling mounting (inverting) the head, the angle bracket must be inverted as well.

(see photo)

Take the camera / lens assembly, place it on a desktop or other ﬂ at surface, with a pen or pencil

underneath. Carefully roll the assembly forward and back until the balance point is found. Using

the photos as a guide, attach the camera/lens to the angle bracket using the included 1/4"-20

x 3/8 button head hardware. Center the balance point you found previously in the center of the

angle bracket.

NOTE: It is very important to make certain the center points are coincident. If they are not, the

front / rear balance will be off, and the pan tilt head may suffer performance degradation to the

point of not working. Please make sure to check the front/rear balance before calling for service.

When centered, tighten the hardware to secure the assembly.

Attach the pre-built supplied cable harness from the rear of the pan tilt to the rear of the camera.

Note that the proper connectors are supplied for your particular camera model for power and con-

trol ports. Attach the lens control cable from your lens to the con nec tor on the rear of the pan tilt

head. If you are using a C mount lens with auto iris, and your camera supports auto iris operation,

attach the four pin link from your camera body to the four pin connector on the lens body.

If using the optional PT-101COMP model with 15 pin pass thru cable for component, RGB, or Y/C

signal output, attach it between the camera body and the 15 pin socket on the rear of the PT-101

head. You must supply your own breakout cable to attach to the 15 pin connector on the base of

the pan tilt head, or buy a specially made one direct from Hitachi. Several conﬁ gurations of cable

are available depending upon your needs. If making your own cable, the pin outs are shown in a

diagram in the camera manual.

If using the optional PT-101SDI model with built in Y/C to SDI converter, make sure that the

selectable output of the camera is set to Y/C signal and not RGB or component modes, otherwise

your picture will be in black and white.
