Throughout this document you will notice certain symbols that bring your attention to important
information. These are Notes and Warnings. Examples are shown below.
Note: Important Notes appear in blue text preceded by a yellow exclamation point
symbol, as shown here.

the subject being discussed.
Warning! All Warnings appear in red text, followed by blue text, and preceded by a red
stop sign, as shown here.
A warning is meant to call the reader’s attention to critical information at a point in the text that is
relevant to the subject being discussed.
Class 1 Laser Information
TL X Extenders and Matrix Switches, like all Thinklogical fiber-optic products, are designed and identified
as Class 1 LASER products This means the maximum permissible exposure (MPE) cannot be
exceeded when viewing the laser with the naked eye or with the aid of typical magnifying optics (e.g.
magnifying glass, eye loupe, etc.).
CLASS 1 LASERS do not require any special
precautions under conditions of normal use.

INTRODUCTION
The Logical Solution
VelocityKVM Fiber-Optic Extension Systems are designed for high performance visual
applications that require video as well as peripheral support. The system allows users, via fiber-
optic cable, to station and operate video monitors and peripherals up to 40 kilometers away from the
controlling computer, securely and without loss of resolution. The VelocityKVM system is designed to
support PS2, full duplex stereo audio, serial (RS-232) and USB 1.0 (HID).
Available options include:
•Single-Mode or Multi-Mode Optics
•USB HID only (eliminates USB 2.0 for added security)
•No Router Mode available or supported on some models (See pg. 13)
•Separate Data Paths for keyboard/mouse (See Appendix E, pg. 60)
•Separate Audio Paths (See Appendix E, pg. 60)
•Multi Path (Multiple Video Paths) (See Appendix E, pg. 60)
•RS-422 serial port for controlling broadcast equipment
•Automatic Fail-Over (See Appendix C, pg. 57)
•Professional Audio TOSLINK, AES and S/PDIF plug-in modules (pg. 12)
VelocityKVM products are ideally suited for a wide range of applications in the broadcast and post-
production field, as well as command/control centers, universities, large scale digital signage and other
commercial KVM applications.
See Option Configuration Diagrams (pgs. 10-12) and Appendix A, Complete Line of Thinklogical’s
VelocityKVM Extenders (pg. 45).
Theory of Operation
Powered by
MRTS Technology
MRTS Technology 6.25 Gbps. Allows Full Frame Rate Transmission of Uncompressed DVI
Powered by Thinklogical’s cutting edge, patented MRTS (Multi-Rate Transmission System) Technology,
this KVM extension system transports every frame of a DVI or RGB video stream seamlessly with no
compression or dropped frames. In addition, all high-speed peripherals function with no latency.
The VelocityKVM Extension System has a simple transmitter/receiver design which allows for ease of
installation and straight-forward deployment. Incorporating standard SFP+ transceivers, the transmitter
and the receiver can be connected by a multi-mode or single-mode fiber optic cable. The transmitter unit
connects to a CPU with the supplied peripheral cables. Local video, keyboard and mouse ports are
available on the transmitter and the receiver unit provides connections to the user interface devices.
The Fiber Extension System
Each system includes a transmitter and a receiver connected by fiber optic cables. The transmitter
connects to the source computer with standard cables and the receiver provides connections to the user
interface devices. Standard VelocityKVM Extenders support PS2, full duplex stereo audio, serial
(RS-232), USB HID and USB 2.0.

Why Fiber?
In heavy-volume, metropolitan area networks, the limit on how much bandwidth or data that can be
carried across a copper line can become a bottleneck for enterprise access and ultimately, for revenue.
Fiber Optic Cable alleviates this problem by offering substantially greater bandwidth.
Multi-Mode Fiber
Transmission Distance (up to 350m using 50/125µm fiber)
Multi-mode is designed for transmission distances such as those found within a single building or facility
and thus, is ideal for multi-channel television broadcast systems. Multi-mode may be used to send video
signals from room to room or floor to floor. The Multi-Mode VelocityKVM Extender allows video and
peripheral transmission distances up to 350 meters using 50/125µm fiber, making it an ideal solution for
in-house applications.
Single-Mode Fiber
Transmission Distance (up to 40 kilometers)
Single-mode is designed for long distance transmissions and thus, is ideal for multi-channel broadcast
systems. Single-mode may be used to send video signals from workstation to workstation, from building
to building, or from studio to transmitter (STL) with a video resolution of 1920 x 1200. Using 9µm fiber
with SM/UPC connectors, the Single-Mode VelocityKVM Extender allows video and peripheral
transmission distances up to 40 kilometers, (25 miles) making it an ideal solution for metropolitan area
networks and most other applications.
Advanced Top-Quality Video Transmission
Fiber optic cable has emerged as a logical solution for next-generation signal routing. The VelocityKVM
product family harnesses this capability and ensures long distance, error-free transmission with no frame
or bit dropping and complete immunity to interference. The result is no degradation of the video or
peripheral signal whatsoever.

No Router Mode
Switching Thinklogical Extenders without a Matrix Switch Router
The No Router Mode on many Velocity Receivers allows hot-key strokes to switch
KMASS ( K eyboard, M ouse, A udio, S erial, S tereo 3D) data control and video sources when
directly connected to multiple Velocity Transmitters. Do not use No Router Mode when
connecter to a router.
All Velocity receivers that support redundancy and/or selectable KMASS can support No
Router Mode. This allows users with a direct connection between one Receiver and multiple
Transmitters to switch video sources and KMASS control with hot-key strokes such as Alt/Alt,
Shift/Shift, etc. (See pg. 16)
KVMA Mode (Vel-4R, Vel-24R Receivers)
Vel-4 Redundant and Vel-24 Redundant Receivers use KVMA mode: Video and KMASS are
switched between two sources. The user only sees the video for the CPU being controlled.
KMA Mode (Vel-24, Vel-34, Vel-35 Receivers)
Units that switch KMASS, but not video, are in KMA mode: Video does not change, just the
source that the user is controlling.
KM Mode (Vel-24, Vel-34, Vel-35 Receivers)
Units that do not switch video or Audio are in KM mode. In KM mode, Audio is received on the
primary L1 fiber only. (Note that in all modes, the back-channel always handles full KMASS.)
The No Router Mode option can be enabled on the Receiver’s front panel. When No Router
Mode is enabled, out of band (OOB) should be disabled. Non-redundant Receiver models
that support No Router Mode include Vel-24, Vel-34, Vel-35. (The menu option on the front
panel’s LCD will display NA or not be displayed at all if the No Router Mode feature is not
supported.)

Page 14
DDC Differences
A Transmitter gets its DDC table from the Receiver. Typically, the Transmitter and Receiver
tables match, but in the KM and KMA modes, there will be a mismatch. A Vel-4 Transmitter
uses DDC Table 1, a Vel-24 Transmitter uses Tables 1 and 2, etc. A Vel-34 Receiver will return
4 DDC tables to a Transmitter. When a Transmitter is connected to L4 or L5 on the Receiver, it
uses the DDC table for the monitor on L1 and L3. Thinklogical therefore recommends using all
the same type of monitors.
Note: To avoid a DDC mismatch, Thinklogical recommends using all the same type
of monitors in No Router Mode.

Using Hot-Keys
VelocityKVM Receivers that support No Router Mode have default Hot-Keys already installed.
At Turn-on, the unit ID will be displayed.
•Ensure OOB (Out of Band) is off when in No Router Mode.
•Do not use No Router Mode when connected to a router.
Default Hot-Key Strokes (These numeric values are fixed for No Router Mode):
11 = Ctrl/Ctrl (Display 1) 88 = Gui/Gui (Display 4)
22 = Shift/Shift (Display 2) 55 = Scroll Lock/Scroll Lock (Scroll up)
44 = Alt/Alt (Display 3) 77 = Scroll down (No default key)
For more information on using hot-key strokes, see Appendix G: Flex Keys, pg. 65.
