FrameGlide Software™ with Spin Browser Dial™ System Elements Explore at the speed of your imagination

User Interfaces Spin Browser Dial

The Spin Browser dial, when coupled with the FrameGlide software, is ideal for exploring dynamic phenomena. Offering essentially infinite dynamic range, the exponentally-scaled interface allows quickly traversing vast amounts of content, yet provides frame-accurate control.

Dial Styles

TechnoFrolics stocks two styles of dial. Both are stainless steel, 3 inch diameter with finger dimple, dual bearing-mounted. The first is self-contained within an 8 inch diameter anodized aluminum dome, and may be removably placed on a tabletop or bolted permanently to an exhibit surface. The second is panel mount for integrating into custom cabinetry where a more minimalist style is preferred. Wiring connections and pricing are identical.

The dome option is preferred by many of our clients. Because we enjoy seeing it as a signature feature in FrameGlide / Spin Browser systems (when suitable to the exhibit design), we offer it at a discount to match the panel-mount cost.

Attaching a Dome-Mounted Dial to An Exhibit

The dome-mounted dial has three 1/4-20 threaded inserts and can be quickly bolted to any exhibit surface. See the 1-to-1 mounting template.

Attaching a Panel-Mounted Dial to An Exhibit

The 4”x4” aluminum panel has four holes sized for #10 screws. It will have either thru holes (Model 2) or holes with a countersink for flat head screws (Model 3). You can mount the panel on either the front of an exhibit's display surface or behind the exhibit's display surface.

Be sure:

See the Bearing Plate Assembly CAD drawings for your model (includes detailed notes) (Model 2), (Model3).

Connecting the Grounding Cable to the Dial

For reliable operation, it is essential that you ground the user interface so visitor-generated sparks do not adversely affect exhibit functioning.

This cable's omission may result in your exhibit being permanently damaged by visitor-generated sparks (and will void the warrantee). See additional information here.


Wiring the Dial to the Computer

The illustrations and notes in this section address a dial-to-computer distance of up to 15 feet, and from 15 to 150 feet. (Note: Be sure to select the proper diagram based on your system's type of adapter, AD4B-S or QSB-S.)

Wiring with a 15 Foot Dial-to-Computer Distance

Connect the dial to the computer, as shown, using the specified components.

Wiring with a 15 to 150 Foot Dial-to-Computer Distance

Connect the dial to the computer, as shown, using the specified components. Be sure to use the guidelines following the diagram regarding connection of a Plenum Cat6E/6/5 Extension Cable.

Connecting a Plenum Cat6E/6/5 Extension Cable

In general it is best to extend the signal from the dial to the quadrature > RS232 serial adapter, rather than have the A/V installer extend the serial signal. The reason for this is that it allows powering the adapter off the computer's power supply, and thus power cycles the adapter when the computer power cycles.

The directions below relate to situations where A/V installer pulls and terminates a Cat6E/6/5 extension cable, rather than using a pre-terminated cable supplied by TechnoFrolics.
