Throughout this manual you will notice certain conventions 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.
A note is meant to call the reader’s attention to helpful information at a point in the text that is relevant
to 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.

Class 1 Laser Information
Thinklogical’s Fiber-optic Extenders and Matrix Switches 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. telescope
or microscope).
CLASS 1 LASERS do not require any special
precautions under conditions of normal use.

1. Thinklogical’s®Q-Series KMASS Modules
1.1. Product Overview
Thinklogical’s Q-Series KMASS Modules provide users with a convenient, cost-effective and
space-saving way to extend audio and USB over fiber. Up to four modules can be housed in a
single, one rack unit Q-4300 Chassis, making the Q-Series an ideal solution where space, security
and economy are vital. And if one module is all you need do the job, Thinklogical also offers a
single-module Q-1300 chassis for desktop applications.
Incorporating standard SFP+ transceivers, the system uses fiber-optic cables to allow the placement
of audio and USB devices up to 1000 meters (3280 feet) away from the controlling computer
without loss of signal or resolution. Installation is plug-and-play and no adjustments are
necessary.
All Q-Series KMASS modules are connected by fiber-optic cables to provide communications
between the transmitters and receivers. The transmitter module connects to a CPU with supplied
audio (unbalanced), USB and PS2 cables. The receiver module provides an interface to the
destination audio and USB devices.

1.2. System Features
Thinklogical’s Q-Series line of KMASS (K eyboard, M ouse, A udio, S erial, S tereo 3D ) Modules
includes a variety of TX and RX models, designed to meet almost any data extension
applications. Each module can be used in our stand-alone Q-1300 Chassis or, for more
extensive applications, our two-module Q-2300 chassis or our four-module Q-4300 chassis,
each of which will support any combination of transmitters and receivers.
The Q-4300’s chassis allows up to four hot-swappable interface modules to be used in a variety of
applications, as either transmitters, receivers, or as transceivers. Q-Series KMASS modules support
two-way, unbalanced audio, high speed USB 2.0 (480 Mbps) and low speed USB HID (1.5 Mbps).
Installation possibilities are expanded with built-in support for either multi-mode or single mode fiber,
making this a convenient and cost-effective solution to transmit quality data signals over long
distances. Each module is hot swappable, and in addition, the standard SFP+ optics (with LC
connectors) are hot swappable/pluggable.
Every Q-Series module is fully compatible with Thinklogical’s TLX, VX and MX Matrix Switch®
product lines.
1.2.1. The Q-Series Chassis
Each Q-Series Chassis provides a framework for mounting, powering, upgrading and
interfacing with a variety of modules that perform the functions of a KVM and video distribution
system. The Q-4300 chassis supports up to 4 modules, features redundant power supplies, an
LCD/button interface and provides convenient upgrade ports for the chassis and modules. Fans
mounted inside the chassis provide cooling and all modules and power supplies are hot swappable.
The chassis may be rack or desktop mounted. Other installable modules include our DVI and SDI lines
of extenders. (See pg. 22 to contact a Thinklogical®sales representative for more details.)
Q-4300 Chassis: (VQS-004300) Supports up to four KMASS, DVI, RGB/DVI or SDI Q-Series
modules. Dual interface and current sharing power supplies. Desktop or 19" rack-mount.
Q-2300 Chassis: (VQS-002300) Supports up to two KMASS, DVI, RGB/DVI or SDI Q-Series
modules. Desktop or 19" rack-mount.
Q-1300 Chassis: (VQS-001300) Supports one KMASS, DVI, RGB/DVI or SDI Q-Series module.
Desktop only.

1.2.2. Mixing Q-Series Modules and TLX Modules in a single Chassis
Besides Q-Series products, Thinklogical also carries the TLX line of 10G extension products in a
modular format. Non-Q-Series modules, such as TLX, are compatible with the Q-4300, Q-2300
and Q-1300 chassis as well as their own CHS-4, CHS-2 and CHS-1 chassis. However, because
VQM modules generate less heat than TLX modules, they were not deigned to allow air-flow through
their enclosures as in TLX modules.
1.2.2.1. Air-Flow through VQM Modules
To avoid over-heating of TLX modules when mixed with non-TLX modules, the simple solution
is to always install all non-TLX modules on the left side of the chassis (as looking from the back
where the modules are loaded) and install all TLX modules on the right side, next to the cooling-
air intake fans (The side next to the power cord receptacles). This will allow proper air-flow over the
warmer TLX modules and will prevent over-heating. This is true for both the Q-4300 and Q-2300
Chassis and for both the CHS-4 and CHS-2 Chassis.
Warning! To avoid over-heating of TLX modules, always install all non-TLX modules
on the left side of the chassis (as looking from the back where the modules are loaded)
and install all TLX modules on the right side, next to the cooling-air intake fans (The side next
to the power cord receptacles) .
Note: Non-TLX modules, such as Thinklogical’s Q-Series (VQM), were not deigned to
allow air-flow through their enclosures as in TLX modules.
To avoid over-heating, always install all non-TLX modules on the left side of the chassis and install
all TLX modules on the right

2. Connecting Q-Series KMASS Modules
All physical connections to the product use industry-standard connectors. Non-supplied cables
that may be needed are commercially available. All connections are found on the rear of the
chassis.
2.1. Fiber Optic Cables
All KMASS TX modules are connected to RX modules through fiber optic cables, either
directly or through a KVM Matrix Switch to provide communication between the transmitter
and the receiver. The standard multi-mode fiber optic cables must be 50 or 62.5 microns, up to 1000
meters (3280’) long and terminated with LC-type fiber optic connectors.

3.1. HID Microprocessor Programming
Each Q-Series KMASS Transmitter Module with USB HID has an HID PORT that serves as both an
HID Microprocessor Programming port and as a USB HID source. Each Q-Series KMASS Receiver
Module with USB HID has an UPDATE PORT that serves as an HID Microprocessor Programming
port.
A transmitter’s USB HID port is to update DEVICE firmware. A receiver’s USB UPDATE
port is to update HOST firmware.
DEVICE HOST
When updating the transmitter device port, the USB cable must be removed from the HID port
while the chassis power is off in order to reboot the module.
