operation.
Note 1: The products described contain a Class 1 laser or LED fiber optic emitter. The following
safety precautions apply.
Warning: Do not disconnect the fiber optic connector while the unit is powered up.
Exposure to Class I invisible optical radiation is possible when the internal fiber optic
connector is disconnected while the unit is powered up.
Caution: Any access to the controls, adjustments, or performing operations, which are
other than those specified may result in hazardous radiation exposure. Permanent eye
damage or other bodily injuries may be resulted from such exposure even for only
seconds.

(2) Product Overview
2.1 Introduction
The FT810DB Series products comprise of either single-mode or multi-mode fiber optic
transmitters and receivers for the optical transmission of EIGHT forward (Tx →Rx) video and
ONE bi-directional (Tx ↔Rx) data signal on one fiber. The products work at wavelengths of
1310nm and 1550nm with either a 9/125um or 62.5/125um fiber for single-mode or multi-mode
transmission respectively.
A non-compressed 10-bit digital video transmission scheme is implemented which supports
video in NTSC, PAL and SECAM formats. Transparent data transmission is also accomplished in
RS232, RS422 and RS485 formats regardless of the type of communication protocol
implemented within the system. Time Division Multiplex (TDM) technology is employed for digital
transmission of forward video and data; whereas optical Wavelength Division Multiplex (WDM)
technology is employed for simultaneous reverse data transmission as well as bi-directional data
transmission.
For single-mode transmission, we also offer specifically designed products for long-haul
transmissions up to 60km. These models include the letter “L” in the suffix, e.g. FT810DB-SSTL
for Tx, FT810DB-SSRLfor Rx, etc.
The FT810DB Series units are available as standalone units, which can be mounted
horizontally or vertically wall-mounted on any fixture. The standalone unit comes with an external
power supply FT-PA/12V, which can be powered by local 110/220V power.
The FT810DB Series units are also available as plug-in card modules installed in a 19”
rack-mount chassis. Each plug-in card occupies one slot in the rack-mount chassis. The rack
mount chassis has to be ordered separately, and comes with its own power supply for powering
the installed card modules.

(3) Installation
3.1 General
All OT Systems products are thoroughly inspected, tested and securely packaged before
delivery to ensure a stable, intact and trouble-free service. Please check the equipment upon
receipt for any visible damage which may have been caused during shipping.
The FT810DB Series standalone units (Fig. 3.1) can be either horizontally or vertically
wall-mounted, or mounted on any fixture. The Standalone unit works with an external power
supply FT-PA/12V powered by local 110/220V power.
The FT810DB Series card modules are housed inside the FT-C18 rack-mount chassis (Fig.
3.2) with an included power supply unit. The whole chassis is powered by local 110/220V power.
FT-C18 is a standard 19” (483mm) rack-mount chassis which occupies 4 rack units (177.8mm) in
height. Each FT810DB card module occupies two slots and a total of 18 cards can be housed
inside the chassis.
3.2 Standalone unit installation
a) Mount the standalone unit onto a fixture, (either on the wall or on a flat surface) with four
screws through the holes on the mounting frame to secure it in position.
b) The provided power supply should also be mounted on the same fixture or in the proximity
for connection of the supply cables to the unit, provided that an AC power supply socket is
nearby for powering the adaptor.
c) Connect all the signal inputs and outputs at the back of the unit with appropriate cables:
fiber optic cable for optical link, BNC cables for video inputs/outputs (Tx/Rx), and UTP cable for
data input/output (Tx/Rx).
d) Once the unit is powered up, check that the red POWER LED on the unit is lit. If not, check
the power supply cable connections between the unit and the power supply socket.
e) With all the signals available at the input and output ports, check the status of LEDs located
on the unit. With correct status of each LED, installation is now completed [for LEDs status, see
Operational Guides on this manual’s section (5)].

3.3 Card module installation
a) Insert the card module into the FT-C18 chassis along the top and bottom card guides of an
empty slot and push the card into the multi-pin socket at the rear firmly. Secure with the provided
thumb screws.
b) Repeat the above procedure for all the rest card modules. Unused slots must be covered
with blank panels provided.
c) Connect all the signal inputs and outputs at the back of the unit with appropriate cables:
fiber optic cable for optical link, BNC cables for video inputs/outputs (Tx/Rx), and UTP cable for
data input/output (Tx/Rx).
d) Once the chassis is powered up, check that the red POWER LED on the front and back
panels of the card modules are lit. If not, check the power supply cable connections between the
chassis and the power supply socket. For failures of individual card’s POWER LEDs, check the
corresponding card modules, whether they have been inserted properly.
e) With all the signals available at the input and output ports, check the status of LEDs located
on the unit . With correct status of each LED, installation is now completed [for LEDs status, see
Operational Guides on this manual’s section (5)].

4.3 Dip switch setting procedures
The only setup procedure is to select the appropriate line terminations and data
transmission formats. Selections must be made by setting the dip switches (Fig. 4.5) through the
access on the front panel.

Industrial practice for line terminations
For RS422 4-wire communication, it is suggested to keep the input and output lines
terminated in the ONE Tx to ONE Rx configuration.
For RS485 2/4-wire communication, the RS485 device can be disabled to stay in a Hi-Z
state. It is very important that the data lines have to be terminated with a resistor being
connected across the pair wires so as to eliminate the residual standing signal waves on the
lines in the Hi-Z line condition. So, it is recommended that the lines should be terminated with the
appropriate resistance. When more than one RS485 device are connected in a daisy-chain
configuration, only the farthest device on the loop, i.e. the device located at the end of the line,
should be terminated; whereas the middles ones are set to “Unterminated” status. See the figure
4.6 below for reference.

4.4 Ground connection
For enhanced safety to reduce the risks of electrical shock and physical damage, caused by
lightning and other power surges, as well as a connection to the surge suppresion devices in the
product, a screw terminal is provided on the Standalone cabinets (Fig. 4.7). It is highly
recommended that the Standalone unit have good ground connections to the buildings ground in
accordance with the local codes.
