Section 1: TLX System Features
The Logical Solution
The TLX48 is a 10G high performance modular Matrix Switch and non-blocking matrix switch that
supports full, uncompressed 4K video with full color depth at 60Hz frame rate for complete, end-
to-end routing of video and peripheral signals over multi-mode or single-mode fiber-optic cable.
This highly reliable and resilient Matrix Switch is expandable from 16x16 up to 48x48, which allows for
flexible deployment configurations. In addition, the TLX48 series provides mission critical dependability
and unrivalled signal integrity. Being protocol agnostic, the switch supports DVI, SDI, HD-SDI, Dual-link
DVI, Dual-link SDI, USB HID, USB 2.0 and audio.
The TLX48 Matrix Switch is available with LC-type fiber, CATx or micro-HDMI connectors (pg. 13).
HYBRID SWITCHING SOLUTION
For Uncompressed, High Resolution Video & KVM Systems
Thinklogical’s TLX Matrix Switches are high performance, modular, non-blocking switches for complete
end-to-end switching of video, audio and peripheral signals over multi-mode or single mode fiber-optic
cable or CATx cable.
TLX switches are protocol agnostic, supporting most video, audio and peripheral signals and allow users
to consolidate all their system switching requirements in a single chassis. TLX Matrix Switches are ideal
for small or large system applications, with switch sizes ranging from 12 ports to 1280 ports. Each port
supports 10Gbps bandwidth, preserving signal integrity to provide uncompressed, high resolution video
with no artifacts, latency or lost frames. Thinklogical’s re-clocking technology ensures that every video and
data stream is delivered in perfect synchronization.
SECURITY
Creating physical separation between potential threats (users) and the target (secure data) is essential to
a secure system design. Thinklogical’s system permits users to access sources up to 80 kilometers
away, with no performance degradation. System administrators can safeguard sources in a centralized
location, allowing users to maintain remote access tothe sources, but with no means to breach the system,
either accidentally or intentionally (such as downloading sensitive information onto a USB drive).
PARTITIONED AND RESTRICTED SWITCHING
To protect data between multiple networks, partitioning allows the switch resources to be divided to
support more than one network without allowing switching between networks. Restricted switching allows
the administrator to manage access on a port-by-port basis. Partitioned and restricted switchingis enabled
through the switch’s firmware, which means a threat would have to physically access the switch to tamper
with the settings. (See Appendix C: Secure Applications, pg. 34.)
Note: CATx Matrix Switching applications do not offer an EAL4 rated level of security.
CATx is not available with the TLX80.
RESILIENCY
TLX switches are designed to maximize system uptime. The modular approach of the TLX allows user to
hot-swap all critical system components, including power supplies (in dual supply models), fan trays,
control cards, input/output cards and pluggable optics. Furthermore, the system can be easily
reconfigured, such asadding additionalinput/output cards for expansion, without ever turning off the switch
or interrupting active signals. Redundant and current-sharing power supplies ensure continuous,
uninterrupted power to the switch. Matrix switches are also configurable to include redundant control
cards with automatic fail-over. Enhanced diagnostics and alarms provide extensive real-timemonitoring
and diagnostics of critical functions of the switch.

Page 7
TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
THE TLX48 MATRIX SWITCH DESIGN
The modular approach of the TLX48 10G Matrix Switch (also referred to as a Switch or Router) allows all
critical system components, including Input/Output Cards, Power Supplies, Control Cards and pluggable
optics (SFP+)to be hot-swappable, thusminimizing down-time duringreconfigurations, updates or failures.
Thinklogical’s TLX48 line replaceable modules include:
•(2) Redundant, Current Sharing Power Supply Modules
•(1) Fan Tray Module (3 fans)
•(2) Control Cards (Primary/Back-up)
•(Up to 3) 16-port Input/Output Cards (Fiber, CATx, HDMI)

•Standard VX Matrix Switch IP Address Configuration Procedure
•Standard VX Matrix Switch SNMP Traps
•VX and MX Matrix Switch 6G I/O cards (6G to 6G only)
POWER SUPPLY MODULES The dual, redundant power supplies ensure continuous,
uninterrupted power. The supplies are current sharing
which means the supplies share the load equally. If a power
supply fails, the redundant power supply can support the
entire current load of one fully populated Switch.
Although the switch functions properly with one power module, Thinklogical recommends that both
modules be used, preferably connected to independent power sources, for redundancy.
Each Power Supply module contains an internal cooling fan.
Additionally, the hot-swappable feature allows easy replacement of a module without interrupting the
Switch’s system functionality. Power Supply status is displayed on the front panel (see below).
TOUCHSCREEN OPTIONS
The TLX48 is offered with a Touchscreen, which allows the user to easily make and break connections
with minimal set up time. The Touchscreen is available in a Front-Mounted or Stand-alone version.
Both options include Power Supply status LEDs.

Page 9
TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
The stand-alone touchscreen is connected via the RS232 serial port on the back of the Switch. The
serial port on the Switch can be configured to work with the touch screen or our ASCII interface. The
Switch ships with the ASCII interface enabled.
ENABLING THE TOUCHSCREEN
To enable the touchscreen, connect the computer's network port to the RJ45 LAN port on the TLX48
using a crossover cable or through a network hub. The TLX48 is shipped with a default IP Address of
192.168.13.15 (which can be changed using the dip switch on the Fan Tray).
Set your computer to use the static address 192.168.13.9 and netmask 255.255.255.0. From here,
open a browser and type in the address of the TLX48 (http://192.168.13.15). Check the Touchscreen
Enable box to allow control of the touchscreen via the serial port.
The names of Sources and Destinations can also be changed easily from this page using the browser.
Set a web browser to the IP address of the TLX48. Make any desired changes to the names and be sure
to press the “SAVE and UPDATE” buttons before disconnecting.
Naming Sources and Destinations
To make a connection, select both a destination and a source (they turn blue when selected) and press
“CONNECT”. To break a connection, select a destination (it turns blue when selected) and press
“DISCONNECT”.
THE CONTROL CARDS
The hot-swappable Control Card connects the TLX48 to an External CPU. The RS-232 serial port
may be used for third party controller integration (such as Crestron, AMX or home-spun interfaces). Also,
the Configurator Software may be used to control the Switch via the LAN port.

Page 10
TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
A Back-up Control Card ensures uninterrupted functionality if the Primary Control Card should fail
or need to be replaced. The Primary Control Card should always be in the left controller slot. The Back-
up Control Card (sometimes referred to as a Secondary or Fail-Over Control Card) must have a LAN
connection that allows it to communicate with both the Primary Control Card and the Configurator server
(required for the Back-up Control Card to take control of the TLX48). Both Control Cards must have the
same CPU Module/Processor. (Also see Safely Remove an Active Control Card or Shut Down of the
System on pg. 24 for more on Primary and Back-up Control Cards.)

Page 11
TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
THE NETWORK INTERFACES
A TLX48 uses up to three IP addresses. The Primary Control Card uses address X and address X+100.
The Back-up Control Card uses address X+1 and will take over address X in the event of a failure in the
Primary Control Card. These addresses are set by an external DIP switch. (See: TLX48 DIP Switch
Settings, pg. 18.) The primary’s IP address can be set from 15 to 45. The default subnet used by the
TLX48 is 192.168.13.xxx. The user may use their own subnet by reconfiguring the switch’s network
startup.
This procedure is detailed in: Manual_How_To_Change_A_TLX_Matrix_Switch’s_IP_Address
The TLX48 uses several network ports for control and status. Port 17567 accepts commands to control
the switch.
The command API is described in the document: Manual_TLX_Matrix_Switch_ASCII_API_V5
There are other ports that can be read to access system configuration and operating data. The actual data
format varies by model and is described in the following sections. There are five blocks of data available
for reading.
These ports are documented in: Manual_TLX_Matrix_Switch_Interfaces
1. Switch connection status (broadcast over port 17564 every few seconds)
•The primary CPU IP address
•Upper or Lower chassis flag
•First port number in this block
•Last port number in this block
•'N' port number values
2. Port settings (UDP port 17565, TLX48 localhost only)
•Port output level value
•Port input enable status
•Input port number (big-endian format)
3. Hardware sensor status (TCP port 17566)
•Reserved for future use.
4. Alarm, Inventory and Power Supply Status (TCP port 17600)
•State of the alarm contacts
•Card Inventory
•Power Supply Status (internal TL use only)
•Switch card temperature readings
5. I/O card data (TCP ports 17601 through 17640, 1 port per I/O card)
•SFP installed bits
•SFP TxDisable bits
•SFP TxFault bits
•SFP LOS bits
•I/O card type
•I/O card temperature
•SFP serial ID data
•SFP Diagnostic data
6. Service Request (LOS) Signaling (UDP port 17560)
The TLX48 can broadcast a message over the network when a remote receiver requests attention. When
enabled, the receiver will toggle its TX pin, causing a LOS (loss of signal) event to occur at the Switch.
When detected, the TLX48 broadcasts an 'Attention Request' message over the network. This message
contains the IP address of the TLX48 and the port number that detected the request. It is left up to an
external system to detect, decode and act upon this request.
•32-bits, TLX48's primary IP address
•16-bits, 0 for the Upper (or only) Switch chassis, 1 for the Lower Switch chassis (in some models)
•16-bits, port number (list starts from 1, not 0)
•16-bits, key code in bits 0 –7, 0x00 and 0xff are ignored

Page 12
TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
SNMP SUPPORT
The TLX48 can be monitored via SNMP Simple Network Management Protocol (supports version V2c
and V3 USM). Please call our technical support staff at 1-203-647-8700 for downloadable MIB
Management Information Base definition files.
There are a few entries in the SNMP configuration file (/etc/snmp/snmpd.conf) that users may want to
modify:
•syslocation Text to aid in locating the unit
•syscontact Name/Phone/email address of a contact
•trap2sink IP address/name of a system to receive SNMP traps
The default name used by trap2sink is 'snmp.trap' and is defined in the file /etc/hosts as pointing to
127.0.0.1. The easiest method to change the trap address is to modify the /etc/hosts entry and not
change the trap2sink setting in the configuration file. You may have multiple trap2sink entries in the
configuration file to specify multiple trap destinations.
NTP SUPPORT
NTP, or Network Time Protocol, is used to keep the internal clock on the TLX48 set to the correct
time. By enabling this service, users keep the Switch’s clock synchronized to an external time reference.
To use the service, users must have a time server running on their network or allow the Switch to access
a public time server. NTP configuration is contained in the file /etc/ntp.conf
Details about NTP configuration may be found at:
http://tldp.org/LDP/sag/html/basic-ntp-config.html
SYSTEM LOG FILES SUPPORT
The TLX48 records system events into files located in the directory /var/log/.If you wish to preserve
log files, you may redirect the logs to another system(s). This is a standard feature of Linux's rsyslogd
program. Redirection is enabled by entries in rsyslog configuration files located in /etc/rsyslog.d/
Details about syslog configuration file entries may be found at: http://www.rsyslog.com/doc/
SERIAL/RS-232 INTERFACES
The Control Card has two RS-232 serial ports. One Control Card is for the Linux command line interface
(labeled CONSOLE), and the other is for the Switch's ASCII command interface (labeled RS232). If a
Back-up Control Card is installed, then its Linux console port is active, but only the RS232 port on the
active Control Card will function.

TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
THE FAN TRAY MODULE The TLX48 uses 3 DC fans located in one modular, hot-
swappable fan tray designed for easy replacement
without interrupting system functionality. The Fan Tray
introduces air into the chassis through air baffles along the
chassis side panel. This cools the horizontally mounted I/O
Cards, the Control Cards and the backplane.
The Fan Tray is also equipped with an annunciator port for
system alarms which can be configured to trigger an external
control system (adapter included) and an external DIP Switch
for setting IP addresses. (See pg. 18)
ALARMS: The Fan Tray is equipped with an annunciator port
for system alarms that can be configured to trigger an external
control system. The dry alarm contacts are Normally Closed
when unpowered, Normally Open when powered (OK
condition) and Closed for an alarm condition.
Maximum switching capacity is 2A at 12V.
Alarm Descriptions for the TLX48
All fan speeds are monitored. Any fan speed that does not meet specification will cause an alarm
condition.
The temperature in the chassis is monitored by internal temperature sensors in several locations.
Sensors located in the Power Supply(s), Fan Tray, on the Control Card(s) and on the I/O Card(s)
monitor continuously for any anomalous conditions.
THE INPUT / OUTPUT CARDS
TLX-MSD-M00016
TLX-MSD-C00016
VXM-DH0016
The TLX48 10G contains up to 3 horizontally mounted I/O Cards. I/O Cards provide the 1st (ingress)
& 3rd (egress) stages of a three stage Clos switch fabric.
The hot-swappable Input/Output (I/O) cards provide in-service expansion capabilities in sets of 16 ports
per I/O card, thus allowing re-configuration without interrupting signal processing.

Page 14
TLX48 Matrix Switch Product Manual thinklogical Rev. H, February 2020
Each standard I/O card consists of one Transmit (T) and one Receive (R) optic per port. I/O Cards are
available with CATX, LC-type fiber or micro-HDMI connectors and can be assembled with Single-
mode or Multi-mode optics (SFP+). Individual I/O Cards list the ports as 1 through 16 on the TLX48. A
blue LED located on each I/O card indicates when power is applied to that card.
The TLX48 can have a minimum of one I/O Card (16 x 16) and a maximum of 3 I/O Cards (48 x 48).
Each TLX48 I/O card contains 16 ports, so that when fully configured, the TLX48 will provide a total of 48
Optical Input/Output connections (SFP+ T/R) described as Ports 1-48. The TLX48 switching matrix
connects any port’s optical output (SFP+ T) to any port’s optical input (SFP+ R).
Optional HDMI Input / EDID Output Cards
Also available with the TLX48 are HDMI I/O Cards with Micro HDMI connectors that support input cable
lengths up to 15 meters and include a USB mini-B connector for FPGA downloads/updates. Sixteen 2-
meter, micro-HDMI to HDMI cables (CBL000107-002MR) and a cable support bracket are supplied with
each card.
Note: When using HDMI I/O Cards, the TLX48 must run:
TLX320_48_control_fpga Rev0x000c and software vxrcntl V4.22.
Port numbers begin at the right and start with the bottom I/O Card
THE DIGITAL CROSSPOINT SWITCH
The Digital Crosspoint Switch is a non-blocking asynchronous switch that can connect any input to any
output of Thinklogical’s TLX, VX and MX Matrix Switches. Video and Data signals are routed in both
directions and the data stream is de-multiplexed at the receiver to deliver uncompressed, high resolution
video, audio and peripheral data at the end-user’s workstation.
Note: The TLX48 supports MX48 I/O Cards to support legacy Velocity extenders.

Unpacking the TLX48
The TLX48 is designed to be mounted in a standard EIA 19” rack. 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 unit.
1Carefully remove the TLX48 from its shipping container. Carefully inspect the entire unit to make
certain that no damage occurred during shipment.
2The I/O cards are installed at the factory to meet your specific configuration. Ensure that the I/O cards
are properly seated in the unit and that all the SFP modules are sealed with a removable dust plug.
The I/O cards are held in place by thumb screw retainers. Ensure that all thumb screws are finger
tight so that all the modules are properly held in the chassis.
3Verify that the power supply(s) is fully seated in the chassis and that the retaining screw is
secure.
4Verify that the fan tray is fully seated in the chassis and that the thumb screws are secure.
Note: If mounting the chassis in a rack, ensure that air flow to the fans is not restricted
(minimum 2” of free space on all sides).
Note: If any of the sensors detect an over temperature condition, power will be removed
from all sensitive components and the system will shut down.
Note: All failure conditions send out notifications prior to shut down. For a detailed list of
the alarm functions, see pg. 13: Alarm Descriptions for the TLX48.
5When the TLX48 has been inspected and found to be in suitable condition, the installation process
can begin.

Ethernet Control
If the TLX48 KVM Matrix Switch is to be controlled via Ethernet, it will require a static IP address. This
value can be set via the DIP switch located on the front of the Fan Tray Module. Factory default setting is:
192.168.13.15 (00000000).

TLX48 DIP Switch Settings
The simplest network connection is an isolated network with only the TLX48, the control server, and any
control clients using static IP addresses. The TLX48 can be set to any of the above settings. The Control
Server must be at 192.168.13.9, and the Control Clients can then be set to any other addresses in the
192.168.13.X subnet.
If static IP addresses for the control server and its clients are not possible, then the control server will
require two (2) network interfaces, with one interface set to the static address 192.168.13.9 and dedicated
to the TLX48 KVM Matrix Switch(s), while the other network interface can be configured as required by
the facility's network administrator.
Redundancy and Network Requirements
ABack-up Control Card (sometimes called a Secondary or Fail-Over Control Card) is optional and
ensures uninterrupted functionality if the Primary Control Card ever fails or needs to be replaced. Two
network requirements need to be in place for a switchover to occur:
The Back-up Control Card must have a LAN connection to the server with the IP address as specified in
the “TLX48 DIP Switch Settings” section above. Without this connection, the Back-up Control Card will
NOT take control of the Switch under any circumstances.
The Back-up Control Card must also have a LAN connection that allows it to communicate with the Primary
Control Card.
Note: It is important that the Network connections be tested. The user should log into the
Back-up Control Card via SSH or Console port and ping the server as well as the Primary
Control Card to verify the connections.
External Control CPU Minimum Requirements
The External Control CPU must meet the following minimum requirements (including requirements
for using Thinklogical’s System Management Portfolio):
•System Management Interface package requires Debian 32 or 64 bit.
•Configurator and Hot Key Manager run on Linux (RedHat 32 & 64 bit,
Debian 32 & 64 bit or Windows XP, 7, and 8).
•RAM (minimum): Linux: 1GB Windows: 4GB OSX: 4GB
•VIDEO: Works with all video adapters. (Not required if the computer is used as a headless server.)
•KEYBOARD/MOUSE: Works with any keyboard/mouse/touchpad. (Not required if the computer is
used as a headless server.)
•NETWORK: One port minimum, although two ports are recommended for security considerations.
•DISK SPACE: Thinklogical programs typically use less than 40 MB.
•SERIAL PORT: 1 optional RS-232 serial port (Crestron/AMX serial access)
Pluggable SFP+ Modules
Each Input and Output card contains rows of SFP+ modules that
serve as the fiber-optic couplers for the fiber cables to and from the
Thinklogical transmitter and receiver extenders. Individual cards can
be removed for easy access to the SFP+ modules.

The SFP+ Optical Module is a 10Gbs Short-Wavelength Transceiver designed for use in bi-directional
Fiber-optic Channel links. The modules are hot-pluggable and operate on 3.3VDC.
Always use dust caps to protect against dust and damage when a fiber-optic connector is not
attached to its coupling device (fiber-optic equipment, bulkheads, etc.). All Thinklogical Matrix
Switch SFPs are fully populated with dust plugs upon shipment.
Note: It is good practice to immediately install dust plugs in unused SFP modules and on
the ferrules of unconnected fiber-optic cables.
Each TLX48 I/O card has 16 SFP+ Modules,
each mounted within a grounded metal
enclosure. Each SFP is locked into its enclosure
with a built-in latch handle that can be opened for
removal or locked for installation (right).
The latch handle spans the two LC ports. Arrows
printed on the handle indicate which port is an
INPUT ( ) and which is an OUTPUT ( ). SFP+ Latch Closed SFP+ Latch Open
LC-Type Fiber-optic Cable
Installing Fiber-optic Cable: The TLX48
switching matrix connects any SFP’s optical
output port (Transmit) to any other SFP’s optical
input port (Receive) with LC-type Connectors.

Handling Fiber-optic Cable: Unlike copper cabling, fiber-optic cable requires special handling.
A small speck of dust or a scratch to the ferrule tip (the end of the connector) can attenuate the
optical signal, rendering the cable inoperable.
Warning! The ends of the connectors (the ferrule) should
never contact any foreign object, including fingertips.
Always install a dust cap immediately on the ferrule of any
unused fiber to protect the tip.
Warning! Minimum bend diameter must be no less than 3”. Be
careful not to kink or pinch the fiber when using ties.
