1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD8816B series is a high-quality fiber optic digital video and data transmission system. The
system consists of the OSD8816BT and the OSD8816BR, which are designed to be used as a pair, and
provide one-way transmission of PAL, NTSC or SECAM video, plus full-duplex transmission of one
data channel.
The OSD8816BT accepts one analog composite video input signal along with one digital data input
signal. The video signal is converted to digital with 10-bit
*1
resolution so as to preserve the quality of
the input signals. The resulting digital signal is multiplexed and transmitted as a digital bit-stream
through the fiber. The OSD8816BT also includes an optical receiver section that decodes the digital
signal transmitted by the OSD8816BR, to provide data output signals. Data can be TTL, RS232, RS485
or RS422 31kHz Manchester or Bi-phase. The OSD8816BT receiver provides adjustment free
operation over the full optical range of the unit.
The OSD8816BR incorporates a high performance optical digital receiver for incoming video and data
signals, and a transmitter that outputs a digital optical signal consisting of one data channel. The unit
provides a constant video output level which is independent of link loss, and data section of the
OSD8816BR is also adjustment free over all link lengths. Data signal interface levels are the same as
those of the OSD8816BT.
The OSD8816BT and OSD8816BR are available in two physical configurations: card or module. The
card versions are designed to fit the 3RU-high 19” OSD370N or OSD350N chassis, which allows
multiple OSD card products to be conveniently powered from and located in the one chassis. The
module case versions are intended for isolated use and require an external power source.
The OSD8816B system can be used with any standard singlemode or multimode optical fiber over a
single fiber for transmission and reception.
*1
Video resolution can be either 10-bit with reverse data only, or 9-bit with duplex data (i.e.
forward and reverse data). See section 1.6 for further details

RS485 2-Wire half duplex is used to connect several devices to the same bus when only one unit
transmits data at a time. All units are normally in high impedance receive mode waiting for data. When
transmission of data is requested, the device waits for a protocol specific turn-around time delay before
transmitting after which it returns to receive mode.
RS485 4-Wire full duplex is used for master/slave arrangement. Devices are polled and respond faster
with no turn-around time delay required between request/response. The receiver is always enabled
allowing the devices to receive data even while responding to a request.
Note: If a link doesn't seem to be working correctly, try swapping the polarity of the data lines on both
ends. Some devices are marked opposite the RS485 standard.

2.2.4 OTHER CONNECTIONS
The video-input signal (eg. from camera) is connected to the video input BNC connector on the
OSD8816BT. The video output signal (eg. to monitor) is connected from the video output BNC
connector on the OSD8816BR.
Data signals are connected to the 8 way terminal block connector as set out in Table 3.
The optical fiber cable must be terminated with the appropriate optical connector. Before connection,
inspect the ends of the connectors to ensure that no dust or dirt is present as it could contaminate the
modem connector and result in poor performance.
If it is necessary to clean the cable connectors, use isopropyl alcohol and lint free tissue to remove
contamination.

2.3 OSD8816B OPERATION
2.3.1 OSD8816BT AND OSD8816BR OPERATION
When using the OSD8816B for the first time, check that the unit is in good condition with no visible
damage.
If a card version is used, insert it in an appropriate slot on the OSD370 or OSD350 chassis and check
that the indicators illuminate accordingly on power up (see Table 5). If a module version (OSD8816BC)
is used, connect the unit to an appropriate power source and check that the indicators illuminate
accordingly on power up (see Table 7).
To connect a video signal, connect a BNC terminated coaxial cable from the camera to the
OSD8816BT. If the camera is operational, the "Video Present" indicator should illuminate ‘Amber’.
Connect a BNC terminated coaxial cable between the BNC socket on the rear of the OSD8816BR and
the video monitor or switcher.
Plug in the optical connectors of the optical cable. If the set-up is connected correctly, the OSD8816BR
"Link OK" LED will change from ‘Red’ to ‘Green’. If a video signal is being received the “Video
Present” indicator on the OSD8816BR should be ‘Amber’; if no video signal is being received this
indicator will not be illuminated.
Plug the digital signal source (data) into 8 way terminal block connector on the rear of the module.
Ensure that the correct signals are connected to the correct pins of Data Input/Output connector as
specified in Table 3.
Ensure that both OSD8816BT and OSD8816BR switch settings are in the same modes (see Table 4).

3MAINTENANCE
3.1 INTRODUCTION
The following section outlines the fault-finding procedure for the OSD8816BT and OSD8816BR
modems. Please take note of the following:
▲ Personnel without appropriate training should not attempt any maintenance except that outlined
below.
▲ If further maintenance is attempted you are warned that every care should be taken to ensure that
internal measurements made while the equipment is operational are taken carefully as some
components within the unit are expensive and may be damaged by failure of any portion of their
support circuitry.
▲ Some components within the unit are Electrostatic (ES) sensitive and Electrostatic Discharge
(ESD) precautions should be taken when performing maintenance upon the unit.
3.2 EXTERNAL INSPECTION
Visually check for the following:
▲ Check that the correct power source is connected to the power socket.
▲ Check that the data signals are connected to the modem correctly and that the distant OSD8816BT
or OSD8816BR modem has been terminated correctly to any external equipment.
▲ Inspect the optical connectors for any contamination and clean using isopropyl alcohol and a lint
free tissue if any contamination is detected.
▲ Check that any external termination resistors are connected if the system configuration requires
them.
3.3 ROUTINE MAINTENANCE
▲ There is no routine maintenance required with the OSD8816BT and OSD8816BR.
