1. Introduction
1.1. Application
Powered by Thinklogical’s™ cutting edge, patent-pending MRTS (Multi Rate Transmission System)
Technology, our StudioPRO Extender (SPE) DVI Extension System transports every frame of a DVI
video stream seamlessly with no compression or dropped frames. In addition, all high speed peripherals
function with no latency. Utilizing standard SFP+ transceivers the system uses multi-mode or single-
mode fiber optic cable to permit the placement of a digital monitor or projector up to 1000 meters
(3280 feet) away from the controlling computer without loss of resolution. Using single-mode SFP+
modules and fiber optic cable, distances up to 40km can be achieved. Installation is plug-and-play
and no adjustments are necessary.
Comprised of two compact units, the SPE transmitter connects to the host computer with standard USB
and DVI cables and the receiver provides four ports for connection of peripheral devices as well as
video connections. External power is required for both the transmitter and receiver units and two
universal AC to 5VDC power supplies are included. In addition, indicator LEDs provide link performance
status at a glance.
The SPE successfully and effectively delivers DVI and USB peripherals when and where you need them.
1.2 Increased Security and Efficiency
The ability to locate the CPU remotely from the monitor and peripherals allows full control of the
computer environment. It is now possible to position the monitor or projector in any setting from office to
lecture hall to boardroom while keeping the computer secure in a controlled location.
1.3 Laser Information
All StudioPRO Extender models are designed and identified as Class 1 LASER products.
CLASS 1 LASERS do not require any special
precautions under conditions of normal use.

3.3 Order of Installation Events
Refer to the SPE Quick Start Guides included in Appendix C on pages 21-24 for detailed installation
instructions.
3.3.1 Fiber Optic Cables
Fiber Optic cables for the SPE system are not included but are available commercially or through
Thinklogical™. Please contact your Thinklogical™sales representative for a quotation on your required
cable length or call us at 1-800-291-3211.
Two to three fiber optic cables must be run between the location of the SPE Transmitter (at the CPU or
other DVI-D video source) and the SPE Receiver (monitor, projector, etc.). The standard multi-mode
fiber cable must be 50 micron, terminated with an LC, SC, or ST-type connector. Single-mode fiber optic
cables with SC APC- or LC-type connectors are available. Be careful to not kink or pinch the fiber cable
as it is being installed and keep all bend radii to no less than 3 inches. Connect your fiber cables (L1Tx
to L1Rx, L2Tx to L2Rx, etc.) to the fiber connectors on each pair of SPE Transmitters and Receivers and
dress the cable to prevent crushing, pinching or other damage.
Figure 5: Fiber Optic Cable with ST and LC-Type connectors
3.3.2 Digital Video Interface (DVI-D) Input –Transmitter
The SPE Transmitter connects to your DVI video source (DVI-D video card) using the provided DVI-D
male-to-male cable (CBL000009-002MR). The Digital Video Interface connector on the transmitter
will not accept other DVI connectors such as DVI-I or DVI-A.

3.5 General Button Usage –DDC Select
The TX and RX units both have a button labeled DDC SELECT. When the data communications fibers
L1 and L2 are connected, either unit will control the state of the DDC operation. Each press of the
button will advance the DDC state from PASS THRU to DYNAMIC to STATIC and back to PASS THRU.
(Because the buttons are small, a firm, fine-tipped device such as a mechanical pencil tip or tweezers
may work best). When the units are disconnected, the DDC state of the TX unit is the master and will be
sent to the RX when data communications are restored.
In PASS THRU mode, the CPU communicates directly with the connected monitor for DDC
information.
In DYNAMIC mode the DDC of the monitor is read from the receiver and stored in the transmitter.
In STATIC mode the DDC information in the transmitter is not changed regardless of changes
made at the receiver end.
There is also a DEFAULT DDC TABLE stored in the device. This table is suitable for use with many
standard PC monitors. THE DEFAULT DDC TABLE CAN ONLY BE LOADED FROM THE TX.
If you wish to restore the Default DDC Table to the product and automatically place the device
into STATIC DDC mode, hold both buttons down for approximately 7 seconds or until you see the
DDC mode LEDs change to Remote Static Mode (LCL LED=Orange and REM LED=Green).
3.5.1 Operation of the DDC Modes
DDC (Display Data Channel) is a VESA standard communications channel between a display adapter
and a video monitor. DDC data is stored in a monitor and describes the monitors characteristics (vendor
name, serial number, frequency range, analog or digital capabilities, etc.). DDC information is read from
the monitor by a video card so the video card can gather Extended Display Identification Data (EDID)
and provide a video format acceptable to the monitor. (EDID is a VESA standard data structure provided
by a computer display to describe its capabilities to a graphics card. It is what enables a personal
computer to detect what kind of monitor is connected.)
As the transmitter emulates a monitor it must provide a DDC table to the video card in order for the
video card to provide images for transport. Some video cards may turn off video output if the DDC is not
present at boot up (missing monitor, hot-plugged or the DDC information does not match expected digital
or analog parameters). Some video cards are more tolerant and will produce video output under many
conditions. Due to the variability of video card DDC handling, Thinklogical™products provide the DDC
support modes detailed below.
3.5.1.1 Dynamic Mode
Dynamic DDC mode is the default and recommended mode of DDC operation. In this mode the RX
will read the DDC from a monitor under two conditions; during power-up and if the monitor cable is
removed and reinstalled. The RX will only read the DDC to RAM (It will not be stored on the RX). Once
the RX has validated the DDC it informs the TX of a change in DDC information.

JANUARY 2010 13 REVISION C
Once informed of a DDC change the TX reads the DDC information from the RX. If the DDC from the
RX is different from that stored in the TX non-volatile memory, the TX writes the new DDC information to
non-volatile memory that the video card can read. The TX then informs the video card that the DDC
information has changed so that the video card can read the DDC and act accordingly. In this mode the
CPU may be booted up with the TX turned off or disconnected from the RX since the TX non-volatile
DDC memory can be read by the video card without TX power.
3.5.1.2 Static Mode
Static DDC mode is typically used in switching situations. In some switching situations the customer
may be using multiple monitors that are all capable of handling the same video resolution but some of
the monitors in the system may cause the video card to turn off the video output. Another possible use of
Static DDC mode is when a video card does not recover from a video cable being hot-plugged while the
system is booted. Static mode resolves these issues by preventing the TX from writing to the non-
volatile DDC memory stored on the TX and static mode prevents the TX from informing the video card of
a change in DDC data. In this mode the CPU may be booted up with the TX off or disconnected from
the RX since the TX non-volatile DDC memory can be read by the video card without TX power.
3.5.1.3 Pass Thru DDC Mode
Pass Thru DDC mode gives the video card direct access to the monitor connected to the RX. This
mode is useful in HDCP (High-bandwidth Digital Content Protection) applications. In Pass Thru DDC
mode the video card can directly write-to and read-from the monitor. The video card will be informed of
the presence or absence of a connected monitor. In this mode there must be a valid data communication
path between the CPU and a connected monitor before the CPU can be booted.
When a Thinklogical™product is supplied to customers it typically comes with a default table that
provides a maximum resolution of 1920x1200. If the customer elects to use the default DDC data in
static mode, the video card will read that the TX (emulating a monitor) is capable of showing 1920x1200.
If the monitor connected at the RX cannot display a resolution as high as 1920x1200 the monitor will not
display an image.
