Installation & Operation

Inertia installation and Operation

The INERTIA Graphics Trans-Converter allows high resolution SUN, SGI, Power PC,
Super VGA, Radius, Quadra, MAC series, Super MAC and E-Machine computer­video to be displayed on VGA and Super VGA devices by converting the signals to
either 640 x 480 or 800 x 600 resolution.

• Because the INERTIA has two buffered outputs, it can simultaneously drive LCD
products and any VGA compatible video display, such as: light-valve projector,
computer monitor, VGA/MAC-only large screen data projector, LCD panel, and
even a VGA/MAC color printer.

• A front panel switch enables selection of either VGA 31.5 kHz (640 x 480) or
Super VGA 35 kHz (800 x 600). With VGA or SVGA selected, both of the
INERTIA’s outputs (RGBS on BNCs and VGA on 15-pin HD) are active, so two
simultaneous displays may be connected.

• A third output (labeled Monitor Output) is provided so that the computer’s local
monitor can display the original computer-video signal and resolution.

Installation

1. Turn the computer and monitor power OFF.

2. Connect the computer/workstation video output to the INERTIA Computer Input
connector (Item I, Page 2) using the supplied cable and adapter if necessary
(see Supplied Cables and Adapters on Page 3).

3. Connect the CPU local monitor to the INERTIA Monitor Output connector (Item G,
Page 2) using the supplied monitor adapter cable (see Supplied Cables and
Adapters on Page 3) as shown in the diagram below.

4. Connect the presentation display(s) using either the RGBS output (Item L, Page

2) or the 15-pin HD output (Item N, Page 2) — or both.

5. Connect the INERTIA’s external power supply to the rear panel Power connector
(Item O, Page 2).

6. Turn on the computer and monitor and select the desired output signal using the
output format switch (Item D, Page 2).

Installation & Operation

Front Panel
A. FREEZE Frame Switch – Press the FREEZE switch button, the LED lights

and the INERTIA will store and output the current frame of video until the
FREEZE switch button is pressed again.

B. Power LED – Indicates power is being received from the 115/230 volt

power supply.

C. Input Format LEDs – Four LEDs indicate the frequency/resolution being

converted to VGA or Super VGA. Refer to Compatibility (Page 3) for key
to the LED format.

D. Output Format Switch – This switch affects both outputs 1 and 2 and

causes the output resolution to change to either VGA (31.5 kHz, 640 x 480)
or Super VGA (35 kHz, 800 x 600). Output resolution indicated by LEDs.

E. Zoom Switch – The Zoom switch makes either the top or bottom portion of

the displayed image to be enlarged for easier viewing of text on a large­screen display.

F. Horizontal (

) and Vertical ( ) Centering – These controls may be

used to move the displayed image side to side, or up and down on the
screen.

Rear Panel
G. Monitor Output – This 15-pin HD female connector provides output for the

computer's local monitor – at its original resolution. Adapter cables are
supplied for conversion to 15-pin D (MAC/Quadra) or 13W3 (Sun/SGI) style
connectors.

H. HIGH Z / 75

ΩΩ

Ω switch – IN for 75Ω termination when not using a local

ΩΩ

monitor. Out when using the computer's own monitor (Local monitor
supplies the termination).

I. Computer Input – The computer's video output connects to this 15-pin HD

male connector. Adapter cables are supplied for 15-pin D (MAC/Quadra) or
13W3 (Sun/SGI) style connectors.

J. H/V / SOG switch – Set the H/V / SOG switch to the H/V position for

computer signals with separate horizontal and vertical or composite sync. In
some isolated cases, setting the switch to SOG is necessary for computers
with sync on green, such as SGI.

K. HI Z / 75

ΩΩ

Ω switch – This toggle switch is for input sync termination.

ΩΩ

L. Output 1 BNC connectors – RGB and composite sync BNC connectors
M. H/V / S switch – Output 2 sync switch - The VGA (15-pin HD) output can be

configured for composite (S) or separate H & V sync (H/V). VGA
compatible displays require this switch to be set in the H/V position.

N. VGA/SVGA - Output 2 connector- VGA or Super VGA output 15 -pin HD

connector

O. Power input connector - Connector for cable from external power supply
