1.THE T-4200 MODULAR CHASSIS
The Logical Solution: Modular KVM Extension / DVI and SDI Support in One Unit
The VelocityKVM line of extenders continues to evolve and add value with exciting new capabilities. The
VelocityKVM T-4200 Chassis is a high reliability, rack-space-saving solution housing the same
capabilities in a 1U chassis that used to require 2U. Featuring a dual interface and current sharing power
supplies, each 1U chassis supports two separate interface modules, allowing users to combine module
options within one chassis.
Available modules support a variety of video display options and all modules support PS2, full duplex
stereo audio, stereo emitter, serial (RS-232), USB 2.0 (up to 480 Mbps) and/or USB 1.0 HID.
Using multi-mode or single-mode fiber, the system allows users to securely locate a display device and
peripherals up to 40 kilometers away from the controlling computer without loss of resolution.
In addition, all high-speed peripherals function with no latency, making it ideally suited for a wide range
of applications in the broadcast and post-production field, command and control centers, universities, air
traffic control, energy production and exploration, and most other commercial KVM applications.

1.3 HARDWARE
1.3.1 Physical Connections
All physical connections to the product use industry-standard connectors. Non-supplied cables are
commercially available. All connections are found on the rear of the unit.
1.3.2 Desktop or Rack Mount
You may choose to place your chassis on a shelf or desktop (rubber feet included), or rack-mount it
using the supplied mounting brackets (EIA 19” rack mountable).
See FIGURE 1, page 7, Mounting Bracket Removal.
The front panel should be visible and unobstructed so that the front panel buttons and LCD
display are accessible.
All connections are made to the rear of the chassis.
The VelocityKVM Extender chassis does not need to be opened or accessed.
The sturdy metal case allows units to be stacked as needed (maximum of 4 units per stack,
with a minimum of 2” clearance between stacks for adequate ventilation).

OPTIONS: All Thinklogical KVM
extenders can be mounted in a
standard EIA 19" rack or on a shelf or
desk-top.
Each mounting bracket is secured
by four screws and can be safely
removed from the transmitter or
receiver unit for desk-top mounting
after power has been removed from
the unit.
All screws should be reinstalled after
the brackets have been removed.

1.3.3 Cooling
The Velocity T-4200 Extender System uses four DC fans to move air horizontally through the enclosure.
Note: Be sure to leave adequate ventilation space on both sides of the units (2”
minimum), especially if the units are being stacked (maximum 4 units per stack).
1.3.4 Hot Swappable Power Supplies
Each chassis is equipped with dual, hot-swappable, current-sharing power supply modules. Each
module has an ON/OFF rocker power switch. When the power supply is ON the LED on the front of the
power supply will be lit.
If a power module fails, the replacement can be swapped with no interruption in unit functionality. To hot
swap a power supply, simply unscrew the module and replace it with a new power supply module.
(Power Modules can be ordered from Thinklogical: part number VTM-000001).

1.3.5 Display Rocker Switch
The Display rocker switch located on the front of the chassis selects which module information is shown
on the LCD. Switched to the right or left, it will show the information for the module located on that side
of the chassis. If there is only one module installed, it will display that module‟s information in either
rocker switch position.
1.3.6 Front Panel Display and Buttons
Note: When you receive your T-4200 Chassis, there will be a removable decal that identifies
each module of your specific configuration located on the front panel display.
The front-panel LCD display should be visible and accessible for system setup. The front panel buttons
are used to configure special video settings and to review existing VelocityKVM Extender configurations.
See Paragraph 3, Front Panel Usage below, for more information on using the buttons and LCD.

®
T-4200 Chassis, Rev. A 11 September 2011
Display Modifiable Description
*DDC
DDC PROM Emula. Mode YES Options are Dynamic, Static and Passthru.
In Dynamic mode, the DDC of the monitor connected to the
RX is read and stored on the TX. The CPU is informed of a
change in DDC and the monitor is read. This is useful when
the CPU can be turned on without a connection to the RX.
Static mode is used to maintain the current DDC regardless
of monitor changes at the RX.
Passthru mode makes the DDC pins look like direct
connections between the TX and RX, allowing the computer
to talk directly to the monitor.
Load Default DDC YES Loads the default DDC stored in the application which allows
1024x768. This puts the TX into static mode.
Acquire DDC YES Gets the DDC table of the unit attached, stores the
information and puts the TX in static mode.
Force DDC Mode YES Used to force the DDC of a monitor to appear as either digital
or analog. Since Velocity products can convert between
analog and digital, sometimes the DDC has to be modified to
match the method of connecting the TX to CPU.
