Getting Started
Most CardModules are installed into the rack frames and system tested in the factory. If
this is an upgrade part, or service exchange item then the module is supplied in a padded
cardboard carton which includes the CardModule, rear connection plate and mounting
screws.
Packaging
The shipping carton and packaging materials provide protection for the module during
transit. Please retain the shipping cartons in case subsequent shipping of the product
becomes necessary. Do not remove the module from its protective static bag unless
observing adequate ESD precautions. Please see below.
ESD Warning
This product is static sensitive. Please use caution and use preventative measures to
prevent static discharge or damage could result to module.
Preventing ESD Damage
Electrostatic discharge (ESD) damage occurs when electronic assemblies or the
components are improperly handled and can result in complete or intermittent failure.
Do not handle the module unless using an ESD-preventative wrist strap and ensure that
it makes good skin contact. Connect the strap to any solid grounding source such as any
exposed metal on the rack chassis or any other unpainted metal surface.
Caution
Periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 Megohms.

Product Description
The O TR 5840 is a high quality Dual 3GBit/s / HD / SD SDI to Fiber Optic Transceiver
(2 x RX, 2 x TX) primarily for broadcast and professional applications.
The O TR 5840 provides two channels of SDI to Fiber Optic conversion and two channels
of Fiber Optic to SDI conversion with two additional SDI inputs on BNC connectors, The
SDI and fiber outputs can be mapped individually to any of the SDI or Fiber inputs.
Inputs can be reclocked, or non-reclocked with auto detection of multirate digital video bit
rates in reclocked mode (270Mbit/s, 1.485 GBit/s or 2.985GBit/s).
The O TR 5840 is part of the series 5000 of CardModules, which offer high quality,
modularity and flexibility in a small form factor ideal for applications where space is at a
premium.

Connections
BNC Video
The O TR 5840 uses standard 75 Ohm BNC connectors. We recommend the use of high
quality video cable for digital video connections to reduce the risk of errors due to
excessive cable attenuation. Max cable lengths the module will support are shown below.
SDTV = 250m Belden 8281 (270Mbits/s)
HDTV = 140m Belden 1694A (1.485Gbits/s)
3GBit/s = 80m Belden 1694A (2.97Gbits/s)
Note. Due to the compact design of the connection plate it will be necessary to
use a connection tool to secure the BNC video connectors.
Optical Fiber
The O TR 5840 provides LC/PC connectors for single mode fiber cables.
Multimode fiber cables can also be used, but this will limit the max. fiber length to approx.
1km.
NOTE: Please take care that surfaces of fiber cables and LC connectors are always
protected against scratching and dust if no fiber cables are connected. Dust and/or
scratches will lead to high attenuation of the optical power transmitted.
Installation
If this module was supplied as part of a system it is already installed in the rack
enclosure. If the module was supplied as a field upgrade please follow the installation
procedure below.
NOTE Observe static precautions when handling card. Please see ESD
warnings on Page 5.
Each Card Module is supplied with a rear connection panel and two mounting screws.
Please follow the following procedure for installation of the card module into the Series
5000 Card Frame.
1. Select a slot in the card frame where the CardModule will be located.
2. Remove the blank connection panel from the rear of the rack (if fitted)
3. Install the rear connection panel using the screws supplied. Do not tighten the
screws fully
4. Slide the CardModule into the card frame and carefully check the CardModule
connects to the rear connection plate. The card should fit easily and should not
require excessive force to insert, if you feel any resistance, there could be
something wrong with the rear connection panel location. Do not try and force the
connection. This may damage the connectors. Remove the rear connection
panel and check alignment with the CardModule.
5. Insert and remove the CardModule a few times to ensure correct alignment and
then tighten the two screws to secure the rear connection plate.

Settings and Control
The O TR 5840 has an integrated micro-controller, which enables the module to be
configured and controlled locally via the dip-switch or from remote when using one of the
optional controllers and control software.
Once set, all settings are automatically saved in non-volatile internal memory. (Flash
RAM) The module will always recall the settings used prior to power down.
Figure 3 –Switch and LED locations

OTR 5840 Reference Manual. Rev 1.2
Page 10 of 17
Switch Settings
Below the switch settings for the 8-position dip-switch are defined.
Switch Function Detail
Dip Switch 1
This switch is used to enable or disable local adjustments. Set to ON enables the setting
of the other dip switches to configure the module. Set to OFF will prevent any switch
settings taking effect.
Note. The module has a microcontroller and Flash RAM. When this switch 1 is set to ON any
configuration settings made on the module with the dip switches will automatically be written into
Flash RAM and stored. (see Auto Store) The module will function normally with the switch left in the ON
position but it is recommended to set it to OFF to prevent accidental changes to the stored module
configuration if the switches are moved.
Dip Switch 2
This switch configures input 1 be reclocked or non reclocked.
ON sets reclocked, OFF sets non-reclocked
Dip Switch 3
This switch configures input 2 to be reclocked or non reclocked.
ON sets reclocked, OFF sets non-reclocked
Dip Switch 4
This switch configures input 3 to be reclocked or non reclocked.
ON sets reclocked, OFF sets non-reclocked
Dip Switch 5
This switch configures input 4 to be reclocked or non reclocked.
ON sets reclocked, OFF sets non-reclocked
Dip Switch 6
This switch configures the source of input 1
ON sets input to fiber, OFF sets input to BNC.
Dip Switch 7

In non-recklocked mode the slew rate of the SDI outputs is not set automatically. With
ON:the slew rate is set to fast (e.g. for HD signals), OFF: the slew rate is set to “slow”
(e.g. for SD signals)
Factory Preset Condition
The O TR 5840 is delivered programmed and preset for the following mode of operation:
Switch 1 ON Local Adjustment Enabled
Switch 2 -5 ON All inputs reclocked
Switch 6-7 OFF Both switchable inputs are fed by BNC
Switch 8 ON Slew rate “fast” in non-reclocked mode
If this is the required mode of operation, then no adjustments are necessary.
Auto Store
If no parameters are changed for 10 seconds then the current settings will be written into
the flash memory automatically. This can be seen by the channel status LEDS flashing
yellow four times.

Alarm/LED Status Indicators
The O TR 5840 module has integral LED indicators, which serve as alarm and status
indication for the module. Function is described below.
Channel Condition Indicators
4 status LEDs are provided on the front edge of the module,
one for each channel (figure 3).
Alarm Indicator
There is also a single alarm LED on the lower edge of the module (figure 3). This is
visible through the card frame front cover and provides a general indication of the module
status.
LED OFF indicates power is lost, or there is a power supply fault.

Control System GUI
When using the module in a system with the optional LYNX control system, all module
settings are available on an intuitive Windows GUI interface.
Any settings made using the control system will override any settings made locally. All
settings are stored automatically in the module’s flash RAM.
The above screenshot shows the complete GUI of the module. The Device Info area
contains information about the module including name and firmware revision. If used as
part of a larger system (using the LYNX central control system) the module’s position and
physical location is displayed above the “locate” button.
Note. The “locate”function is a tool used to quickly identify a module in larger
systems. Selecting “locate” will flash the module alarm LED yellow. (This does
not effect module operation)
The first screen displayed when the module is selected is the Main Tab. This is a
graphical representation of the module’s overall function and signal flow.
The area at the bottom of the screen is the error log. Any fault condition (or event) will be
time stamped and entered into the log.
There are a number of “Tabs” along the top of the screen, which splits up the module
settings into a number of logical displays. The various GUI screens and primary functions
are described below.

OTR 5840 Reference Manual. Rev 1.2
Page 14 of 17
Main Tab
This screen is the main interface and is presented first when the module is displayed in
the GUI.
The input detection indicates the bit rate (SD-SDI = 270MBit/s, HD/3G-SDI = 1.5 GBit/s or
3GBit/s) of a connected signal. If no signal is detected the color of the input detection will
turn red and declare the input as missing.
The flex lines at inputs 1 and 2 allow the user to switch between electrical and optical
input. (green box)
The received power of the optical inputs is indicated in dBm.
The four check boxes enable or disable the input reclocking of the respective input.
The flex line nodes to the right of the reclocking checkboxes can be freely reassigned to
any other node in that group. This also allows a single signal to be reassigned to multiple
outputs at the same time. (red box)

OTR 5840 Reference Manual. Rev 1.2
Page 15 of 17
Events Tab
The Events Tab is where the module alarming and error notifications are configured for
the module.
The GUI has an integrated error log, which is a simple text log file stored in the controller
PC. This will record an event and timestamp it. The log can be seen at the bottom of the
GUI screen and can be scrolled through using the scrolling bar.
Log in GUI Function
Events are selectable and you can choose if you want to record a particular event in the
log (or not) or configure it to only record one part of the event. (For example you might
want to log when a SDI input was removed but do not want to log when it comes back).
The ON/OFF trigger can be configured for each of the available events shown in the list
and is set up using the checkboxes provided.
Event Enabled
By default all alarm conditions are activated (checked), by de-selecting a specific alarm
condition in this column, you are telling the module to ignore this condition completely. It
will not color the Alarm LED, log an event in the GUI or send an SNMP trap. This is
useful if for example you never have anything connected to input 2 and want the card to
ignore this input condition completely, you would simply de-select “SDI Input 2 No Input”
and it will be ignored.
SNMP Support
If the system is using an RCT 5031 Master Controller and the SNMP option is installed
then the “SNMP Trap” columns become available.
Here you can configure what events are to be transmitted as an “SNMP trap” into the
network. (This has no impact or influence over the internall error log maintained by the
LYNX control system)
(Internal LYNX error logging and external SNMP traps can be configured independently).
Note. The simulated event is part of the GUI simulator and allows us to force a
particular error condition for testing and demonstration purposes.
