SAFETY INSTRUCTIONS AND
COMPLIANCE DECLARATIONS
PLEASE OBSERVE THE FOLLOWING SAFETY
PRECAUTIONS AS OUR PRODUCTS CONT AIN
CLASS I LASER PRODUCTS
WARNING
Do not disconnect the fiber optic connector while the unit is powered
up. Exposure to laser radiation is possible when the laser fiber optic
connector is disconnected while the unit is powered up.
Although the fiber optic connectors in this product emit only Class 1
energy that is below the levels considered to be hazardous, one should
never stare directly into a fiber optic connector or an unconnected fiber
end unless one can be certain that no exposure to laser energy could
occur.
CAUTION
This manual is intended for use by trained service personnel. The use
of controls, making adjustments, or performing operations other than
those specified may result in hazardous radiation exposure.
The following label or equivalent is located on the surface of laser products.
This label indicates that the product is classified as a CLASS 1 LASER
PRODUCT.
CLASS 1 LASER PRODUCT
SURGE PROTECTION DEVICE RECOMMENDED
This product contains sensitive electrical components that may be
damaged by electrical spikes, surges, electric shock, lightning strikes,
etc. Use of surge protection systems is highly recommended in order

1.0 PRODUCT DESCRIPTION
The 235 system provides simultaneous transmission of digitized S-video,
stereo audio, and/or data over one or one pair of fibers. Unidirectional
235 system transmits two (2) audios (or one (1) stereo audio pair) and
one (1) baseband S-video channel in one direction. The bi-directional 235
system transmits and receives two (2) audios (or one (1) stereo audio
pair), one (1) baseband S-video channel, and one (1) serial data
(RS-232/RS-422) channel in both directions. The video and audio quality
in the 235 system exceeds professional standards. In addition, the 235
can be configured to transmit two (2) NTSC/P AL video, instead of one (1)
S-video. Many versions of optical transmitter and receiver combinations
are available to address different distance requirements.
The 235 features a digital fiber optic transmission technology , capable of
providing sharp video and crisp audio, with little or no maintenance, high
functionality reliability , and low operating cost. The quality of video, audio
and data transmission in BCI's digital designs is much superior to the
analog transmission designs used by other manufacturers (based on
amplitude or frequency modulation). No user adjustments are required
in the 235 system, enabling quick setup and trouble-free operation.
The 235 comes with two packaging options: a rugged, standalone, and
compact unit, or a plug-in card for a card cage system. Panel connectors
are provided for video (DIN and BNC), audio (terminal block), data (terminal
block), and fiber connection (FC-type for singlemode fiber or ST-type for
multimode fiber). They are also easily monitored by separate LED
indicators for power, optical link, and channel activity .
Due to its digital transmission design, the 235 is capable of addressing
a variety of non-standard configurations. Note that Figures 1-1 and 1-2
illustrate the various 235 models.

2.0 SETUP
The BCI 235 Series units are used in pairs. One 235-T transmitter unit
is located at the near-end and connected through one optical fiber, to
the 235-R receiver located at the far-end of the link. For the 235-TRX,
equal transceivers are located at both near-end and far-end locations
and connected through two optical fibers. Connections are one to one
between both units. For WDM applications, the 235-TRX units are
configurable for one fiber connectivity . Figures 2-1 and 2-2 depict typical
installations for the 235-T/R and 235TRX, respectively .

2.1 Mounting
Before installing the units into your housing, make sure there is
enough space to pull and connect both the electrical and optical
cables without stressing them beyond the manufacturer’s
limitations (also known as the minimum bend radius).
2.2 Cabling and Connectors
In order to setup the BCI 235 properly, make sure to observe
the following instructions when installing the proper cables. The
235 requires two parts to the cabling setup: the electrical and
the optical.
2.2.1 Electrical Cable Connection
The three available cable connections on the electrical side are
for video, audio and data connections. Follow the proceeding
instructions in order to properly install your electrical
connections.
2.2.1.1 Video Interface
The 235 is capable of receiving and transmitting one baseband
S-video signal unidirectionally/bi-directionally , respectively . The
video signals are connected through an S-video cable (e.g.,
RG59U). Use the following procedure for installing video devices.
For the near-end TX unit, connect and label one S-video cable
to the user’s video source connector labeled “VIDEO OUTPUT”
(e.g., camera) and connect the other end of the cable to the
235 “S-VIDEO” connector. (See Figure 2-3). Note that the
user can also connect two NTSC/P AL sources through “Video
1 and 2” BNC connectors.
