1.0 PRODUCT DESCRIPTION
The BCI 250E/260E Series is a high performance unidirectional/
bi-directional transmission system capable of carrying simultaneous
broadcastqualityanalogvideo, audio,and/or datasignals. The standard
singlechannelmodels(250E/260E)willtransportonechannelofbroadcast
qualityanalog video,twoaudio channels,and/orone serialdata channel
(RS-232/RS-422)overmultimode or singlemode fiber. The 250E/260E
hasaloop-thoughvideomonitoringportintheTXunitandhastwooutput
video ports in the RX units. The video quality in the 250E/260E system
meets250Cshorthaulspecifications,whileitsaudiospecificationsexceed
professionalstandards.Manyversionsofopticaltransmittersandreceivers
canbe used inthe250E/260Eto address adifferentdistance coverage.
The 250E/260E features a digital fiber optic transmission technology,
capableofprovidingsharpervideoandcrispaudio,highfunctionalreliability,
and low operating cost with little or no maintenance. The quality of the
video,audioanddatatransmissionissuperiortotheanalogtransmission
systems(based onthecounterparts amplitudeor frequencymodulation)
schemes. Nouseradjustmentsare required in the 250E/260E system,
enablingfor a quick setupwithtrouble-free operation.
The 250E/260E comes in two packaging options: a rugged standalone
unit, or a plug-in card for a card cage system. Panel connectors are
providedforvideo(BNC),audio(terminalblock),anddata(terminalblock),
andfiberconnection(FC-typeforsinglemodefiberorST-typeformultimode
fiber). They are also easily monitored by separate LED indicators for
power, optical link,andchannel activity. SeeFigure1-1 for thefrontand
rearpanelsof a 250E.
Due to its digital transmission design, the 250E/260E is capable of
addressinga varietyofnon-standard configurations.

2.0 SETUP
The BCI 250E/260E Series units are used in pairs. For unidirectional
applications, the 250E transmitter is located at the near-end, while a
250E receiver is connected at the far-end through one fiber. For
bi-directional applications, one 260E transceiver unit is located at the
near-endandconnectedthrough two optical fibers to an identical 260E
transceiverlocatedatthefar-endofthelink. Eachunitprovidesaseparate
electrical interface connector for the audio, video, and data signals.
Connections are one to one between both units. Figure 2-1 depicts a
typical installation.

2.1 Mounting
Beforeinstallingtheunitsintoyourhousing, make sure there is
enoughspaceto pull andconnectboththe electrical andoptical
cables without stressing them beyond the manufacturer’s
limitations (also known as the bend radius minimum). Rack
Mountkitsareavailablethroughspecial order.
2.2 Cabling and Connectors
In order to setup the BCI 250E/260E properly, make sure to
observe the following instructions when installing the proper
cables. The250E/260E requires twopartsto thecablingsetup:
the electrical and the optical. For the optical part, observe the
following procedures, as there are various types of optical
connectorsas illustrated on the following page.
2.2.1 Electrical Cable Connection

Each 260E unit is equipped with either an RS-232 or
an RS-422 interface, which is preset at the factory.
Followtheproceedinginstructions depending on what
data type you have installed.
RS 232 Unbalanced Data
The260E units transport unbalanceddatasignals with
handshaking control, and are compatible with Full
Duplex RS-232 (C, D, and E) type devices. Use the
following steps for connecting data transmission
equipment:
1. Connectyour serialdata cableto theuser’s RS-232
device. (SeeFigure2-5).
2. Connect the other end of this cable to the front
panel RS-232 female terminal block connector of

2.2.2 Optical Fiber Connection
Most cable manufacturers identify individual fibers in the fiber
cable. Selectanappropriateterminatedfiber. Eachunit’soptical
ports in the system are specified for use with Multimode
(62.5/125 micron) fiber, or Singlemode (9/125 micron) fiber.
Follow the ensuing instructions for installing and connecting
the fiber optic links:
1. Ensure the power is off before proceeding with the fiber
optic cable installation.
2. Prior to connectingthefiber opticcables, removeand save
the dust caps from the optical port of both the 250E/260E
unitsand the user’sdevice. Cleanthe fiber opticconnector
andusealint-freeclothdampenedwithalcoholtothoroughly
wipe the side and end of the ferrule. Table 1 shows the
connection mechanisms for both ST and FC connectors.
3. Cross-connect the fibers from one unit to the other

2.4 AC Power Connection
Congratulations! You are now ready to power up the BCI 250E/260E
and set up your network connection. In order to make sure that you
haveaproper installation, please observe thefollowing:
1. Your AC jack has power.
2. Your electrical system has proper grounding (this ensures
that your power supply does not suffer from voltage
variations).
3. Power Surge Protection. This is optional, but highly
recommended. AUPSsystemprovides voltage regularity
as well as prevents spikes from occurring, thus protecting
your250E/260Efrom sensitive voltage conditions.
The250E/260Ederives powerfromaninternalpowersupply. Thispower
supply is a 95-240 VAC, 50-60 Hz, at 0.8A. This power supply comes
standard for the 250E/260Eunless otherwise specified.
To provide power to the 250E/260E, simply connect the power cord,
alreadyprovidedwiththe units, and connect it to thewalljack. (You will
findone powercordper unit). Oncethepower cordhasbeen connected
to the wall jack, connect the other end of the cord and turn the switch
on(I).
Ifyouhaveanyproblemsorconcerns,regardingtheinstallation,make
sure that you have taken the proper steps to ensure a proper power
connection. Otherwise, feel free to contact us for any questions you
mayhave.
3.0 OPERATION
After the installation procedure is completed, the units are ready for
operation. To operate the BCI250E/260E units, simply apply power as
indicated in the previous step. Note that the following front panel link
status indicator, shown in Table 2(a) and Table 2(b), will be activated.

4.2 Troubleshooting
If the BCI 250E/260E units do not operate properly after
installation,check forpossiblecablebreaks,loose connections,
and incorrect cable connections. If a problem exists on the
fiber link, please check your fiber connectors for improperly
cleaned fiber cables and connectors. If problems persist that
maybefiber related, contact BCI at1-800-214-0222forfurther
assistance.

For electrical problems, perform the following troubleshooting
procedures:
1. If the POWER indicator is OFF, check for the following:
a. The line cord is plugged into the unit and your outlet
haspower.
b. The 250E/260E unit is switched on.
2. If the POWER indicator is ON, but the Optical Link
indicator is OFF, check for the following:
a. Makesurethe appropriate (Singlemode orMultimode)
fibersarebeing used.
b. Fiber and fiberconnectorsare not broken. Ensure that
the optical loss does not exceed the specified optical
powerattenuation.
c. For each unit, the transmit (TX) fiber is connected to
theotherunit’s receiver (RX).
3. If the POWER indicator and Optical Link indicator are
ON, but the audio/video channels are not operating,
then:
a. Checkto seethat theattacheduserequipmentisturned
on.
b. Bothends ofthelink areconnectedto thecorresponding
equipmentandto thesamecorrespondingchannelport.
c. Cable connections at both the video/audio channels
aresecurelyfastenedtoeachconnector. Turnthepower
off, then back on to reset the link.
d. Outputlevels of theuser’svideo andaudiosources are
not above the allowed input levels of the 250E/260E
units.
