TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
Section 1: TLX System Features
The Logical Solution
The TLX48 2RU is a 10G high-performance, modular, 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, all within a one-
third reduction in weight and form factor from its predecessor.
This reliable and resilient Matrix Switch is expandable from 24x24 to 48x48, allowing for flexible
deployment configurations. In addition, the TLX Matrix Switches provide mission critical dependability and
unrivalled signal integrity. The protocol agnostic switch supports DVI, SDI, HD-SDI, Dual-link DVI, Dual-
link SDI, USB HID, USB 2.0 and audio.
The TLX48 2RU is available with multi-mode and single-mode LC-type fiber connectors, pg. [17].
Hybrid Switching Solution
For Uncompressed, High-Resolution Video & KVM Systems
TLX Matrix 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. System administrators can safeguard sources in a centralized location, allowing
users to maintain remote access to the sources, but with no means to breach the system, either
accidentally or intentionally (such as downloading sensitive information onto a USB drive). Thinklogical’s
system permits users to access sources up to 80 kilometers away, with no performance degradation.
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 switching is 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 on pg. [33].
Note: CATx Matrix Switching applications do not offer an EAL4 rated level of security.
CATx is not available with the TLX48 2RU, TLX80, TLX160, TLX640 or TLX1280.
Resiliency
TLX Matrix Switches are designed to maximize system uptime. The modular approach allows users to
hot-swap all critical system components, including power supplies (in dual supply models), fan tray,
control cards, annunciator module, input/output cards and pluggable optics. Furthermore, the system can
be easily reconfigured, such as adding an additional input/output card, 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. Strategically placed sensors and alarms provide real-time monitoring and
diagnostics of critical switch functions.

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
The TLX48 2RU Matrix Switch Design
The modular approach of the TLX48 2RU 10G Matrix Switch (sometimes referred to as a Switch or Router)
allows all critical system components to be hot-swappable, including Input/Output Cards, Power Supplies,
Annunciator Module, Control Cards and pluggable optics (SFP+), thus minimizing down-time during
reconfigurations, updates or failures.
Thinklogical’s TLX48 2RU line-replaceable modules include:
•(2) Redundant, Current Sharing Power Supply Modules
•(1) Fan Tray Module (3 fans)
•(2) Control Cards (Primary and Back-up)
•(Up to 2) 24-port Fiber-optic Input/Output Cards
•(1) Line-replaceable Annunciator Module with external DIP Switch and Alarm terminal

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
Product Compatibility
The TLX48 2RU is compatible with the following Thinklogical®products:
•Single & Multi-Mode TLX 10G KVM and Video Extenders (10G to 10G only)
•Single & Multi-Mode Velocity/Q-Series 6G KVM and Video Extenders (6G to 6G only)
•SDI Xtreme 3G+ Extenders
•System Management Portfolio
•Standard TLX Matrix Switch ASCII Interface (via RS-232 port or via Network port)
•Standard TLX Matrix Switch IP Address Configuration Procedure
•Standard TLX Matrix Switch SNMP Traps
Power Supply Modules
The dual, redundant power supplies ensure continuous, uninterrupted
power. The supplies are current sharing which means they share the load
equally. If a power supply fails, the redundant power supply can support the
entire current load of one fully populated Switch.
Each Power Supply module contains an internal cooling fan.
TLX-MSM-P20048:
•Universal input 100-240VAC, 50-60Hz, 1.5A.
AC-DC 650 Watt, 12V/54.2A Main Output.
12V Standby Output, 2A max. Output Current.
Front-End Power Supply with back to front airflow.
Although the switch functions properly with one power module, Thinklogical recommends that both
modules be used, preferably connected to independent power sources, for redundancy.
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.
PS1 PS2
If operating the TLX48 2RU with one power supply, it should beinstalled in the left (PS1) receptacle.
A supplied filler panel should be installed to cover the right receptacle.
Also see How to Remove and Replace a Power Supply, pg. [25]
Power Supply filler panel.

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
The Control Cards
The hot-swappable Control Cards (also referred to as Controllers)connect the TLX48 2RU to an
External CPU. LAN Ports are available in either fiber-optic or copper RJ45 configurations. The RS-232
serial port may be used for third-party controller integration (such as Crestron, AMX or home-spun
interfaces). Also, the SMP Software may be used to control the Switch via the LAN port.
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 lower controller slot (CTRL 1).
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 SMP (required
for the Back-up Control Card to take control of the TLX48 2RU). For more on Primary and Back-up Control
Cards, see Safely Remove an Active Control Card or Shut-down the System on pg. [23].
*See pg. [26]for ordering information.

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
The Network Interfaces
A TLX48 2RU 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 2RU DIP
Switch Settings, pg. [15]. The primary’s IP address can be set from 15 to 45. The default subnet used
by the TLX48 2RU 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 2RU 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 2RU 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 I/O card type
SFP TxDisable bits I/O card temperature
SFP TxFault bits SFP serial ID data
SFP LOS bits SFP Diagnostic data
6. Service Request (LOS) Signaling (UDP port 17560)
The TLX48 2RU 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 Switch broadcasts an 'Attention Request' message over the network. This
message contains the IP address of the TLX48 2RU 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 2RU'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

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
SNMP Support
The TLX48 2RU 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.
Some entries in the SNMP configuration file (/etc/snmp/snmpd.conf) that users typically modify are:
•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 2RU 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
rsyslog.d 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 Port 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.
Linux Command Console (Console)
•Baud Rate: 115200
•Data Bits: 8

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
The Fan Tray Module
The TLX48 2RU 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. Do not allow the TLX48 to operate without a Fan Tray for more than 90 seconds.
The Annunciator Module
The hot-swappable Annunciator Module is equipped with a ten-port terminal 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. [15]. The module also features air baffles for additional output ventilation.
Note: Always ensure the DIP Switch settings on a replacement Annunciator Module match
the settings on the removed Annunciator Module or a desired new setting.
Critical Hardware Alarms: 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.
All fan speeds are monitored and any that do not meet specification will cause an alarm condition.
The temperature in the chassis is continuously monitored for any anomalous conditions by internal
sensors in the Power Supply(s), Fan Tray and on the Control Card(s) and the I/O Card(s).
•(Pin 4) Temperature Warning –The upper limit is 60°C (140°F) by default.
•(Pin 5) Temperature Shutdown –The upper limit is 65°C (149°F) by default. This feature can be
enabled or disabled, with disabled being the default state. To enable the High Temperature Shutdown
feature, modify /etc/default/tlxcntl as shown below:
1. Add "--enable-high-temp-shutdown" to TLXCNTL_ARGS=
Power cycle the TLX-48 2RU or use command systemctl restart tlxcntl.

TLX48 2RU Matrix Switch Product Manual thinklogical Rev. B, May 2022
The Input / Output Cards
The TLX48 2RU contains up to 2 horizontally-mounted I/O Cards.
The hot-swappable Input/Output (I/O) cards provide in-service expansion capabilities in sets of 24 ports
per I/O card, thus allowing re-configuration without interrupting signal processing.
Each standard I/O card consists of one Transmit (T) and one Receive (R) optic per port. I/O Cards are
available with LC-type fiber connectors and can be assembled with Single-mode or Multi-mode
optics (SFP+). Individual I/O Cards list the ports as 1 through 24. A blue LED located on each I/O card
indicates when power is applied.
The TLX48 2RU can have a minimum of one I/O Card (24 x 24) and a maximum of 2 I/O Cards (48 x
48). Each TLX48 I/O card contains 24 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).
Port numbers begin at the left 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.

Ethernet Control
If the TLX48 2RU 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 Annunciator (ANNC) Module. Factory
default setting is: 192.168.13.15 (00000000).
TLX48 2RU 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 2RU KVM Matrix Switch(s), while the other network interface can be configured as required
by the facility's network administrator.
The Annunciator Module is a line-replaceable unit. Always ensure proper DIP Switch settings when
replacing an Annunciator Module.

Pluggable SFP+ Modules
Each Input and Output card contains a row of twenty-four SFP+ modules that
serve as the fiber-optic couplers for the fiber cables to and from the Thinklogical
transmitter and receiver extenders. Individual SFP+ modules can be easily
accessed without removing the cards.
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 2RU I/O card has 24 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

The Controller Card LAN Port SFP
Each TLX48 2RU Controller Card is available with either a fiber-optic or
copper RJ45 SFP Module. The RJ45 SFP accepts a CATx cable. Either
configuration connects the Controller to the external Control CPU.

optical output port (Transmit) to any other SFP’s
optical input port (Receive) with LC-type
Connectors.
Requirements
Thinklogical recommends LC-ty[e SX+ Laser Enhanced (50µm) fiber for the TLX48 2RU KVM Matrix
Switch and Extension System. OM4 Multi-mode fiber can extend up to a maximum of 400m and Single-
mode fiber can extend up to 80km.

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.

Routing Thinklogical Extenders through the TLX48 2RU
Comprised of a fiber-in, fiber-out matrix switch and fiber-optic KVM Transmitter and Receiver Extenders, this
complete system provides transparent and secure routing, switching and extension of video and high-speed data
peripherals to remote destinations with ease.
Matrix Switch Transmit / Receive Concept
Connecting to the Receiver
The Receiver serves as the Destination (desktops, theaters, conference rooms, editing suites, control
consoles, video walls, etc.). Depending on your configuration, your KMASS devices (audio, keyboard, mouse,
etc.) are connected to the Receiver first, using standard cables. Power can then be applied to the unit. The
Receiver then connects to the TLX48 Receiver ports using fiber (Multi-mode fiber for distances up to 400m;
Single-mode fiber for distances beyond 400m).
Connecting to the Transmitter
The Transmitter serves as the Source (computer and video entities). If the source includes a workstation,
depending on your configuration, your local KMASS devices(audio, keyboard, mouse, etc.) should be connected
first. The video sources (e.g., computers, tape decks, etc.) are connected next, followed by any local video
devices. Power can then be applied to the unit. The Transmitter connects to the TLX48 Transmitter ports using
fiber-optic cables (Multi-mode fiber for distances up to 400m; Single-mode fiber for distances beyond 400m).

Routing Thinklogical®TLX Extenders through the TLX48 2RU
Connecting to a Control CPU
The TLX48 2RU is controlled via a dedicated external Control CPU. This allows for customization as well as
ease of control and administration. Access is provided via fiber-optics, CATx or serial RS-232.
Note: The Control CPU (Computer) is supplied separately.
The network andserial RS-232 connection both use the same low-level ASCII API syntax. This command syntax
is defined in the document: Manual_TLX_Matrix_Switch_ASCII_API_V5.Each line contains only one
command and must end with a carriage return (CR) and line feed (LF), or just a line feed (LF). The characters
are not echoed.
The serial port is configured for 9600 baud, 1 stop bit, no parity, and no flow control. The network interface listens
on TCP (Transmission Control Protocol) port 17567. It accepts the same commands as the serial interface. You
may use telnet to manually open a connection and control the TLX48 using port 17567.
Third-party controllers will control the Switch by connecting to either the serial or network port. Automatic fail-
over requires a Network connection.
Thinklogical offers a web-based control program called the System Management Portfolio, or 'SMP.' This
program is described in greater detail in the documents: Manual_SMP2 and Manual_SMP3, available on the
Thinklogical web site.
