Fiber Information
This unit was manufactured with attention to fiber cleanliness by TKH Security Solutions USA. Beyond the optical
safety information contained in this manual, the following guidelines should be observed when working with
optical fibers.
The biggest problem is dirt!
It takes very little contamination to cause problems with optical fiber connections; cleanliness is extremely
important to proper operation of optical equipment.
1. Protect optical connectors by leaving the connector covers in place on unused fiber connections and on the
fiber tips themselves.
2. Personnel who remove and replace fibers should be equipped with a fiber cleaning kit. These are inexpensive
and can be obtained from any fiber equipment supply house. If you choose to, you can use propanol and lint-
free tissue to clean fibers.
a. Do not use isopropanol alcohol (typically called rubbing alcohol) mixed with water. This can cause
additional spots. (Caution: Pure isopropanol is very flammable! )
b. Use lintless tissues to clean fibers.
c. Clean the fiber with a folded tissue moistened with the propanol, pulling the connector tip across the
tissue, then turn the connector 90 degrees and repeat in a different spot on the tissue.
d. Don’t pull the fiber across and then push it back. This will put the dirt that was cleaned off back on
again.
e. Repeat the process on a dry, folded tissue.
3. When removing fibers, always clean them when replacing them no matter how long you had them off.
4. When connecting fibers, pay attention to the bend radius of the fibers. A general rule is to have a 3-inch
(8 cm) bend radius. A bend radius less than 3 inches is an attenuator and can cause optical signal loss.
5. Installers of fiber equipment should be equipped with the equipment manuals and an optical power meter to
measure the optical inputs and outputs in a system. An optical power meter is an inexpensive tool that can
save much time and effort in getting optical communications links up and running. Properly equipped and
trained installers can quickly determine the source of any problems that occur.
External Wiring Information
Cable assemblies with lengths external to the unit not exceeding 3.05 meters, coiled or uncoiled, may be
constructed of jacketed appliance wiring material suitable for the maximum voltage current and temperature,
rated VW-1 or FT-1 or better. Cable assemblies with lengths external to the unit not exceeding 3.05 meters, coiled
or uncoiled, and supplied by a limited power source or NEC Class 2 source of supply as defined in the National
Electric Code, ANSI/NFPA 70, may be constructed of materials rated VW-1 or FT-1 or better with no additional
requirements.

Functional Description
The 9245DT transmitter accepts a composite video signal in NTSC or PAL format via the BNC video input port. This
baseband video signal is sampled at a 16 MHz rate by an A-to-D converter operating with nine bits of precision.
Data signals are combined into the bit stream and converted to an optical signal for transmission over the optical
fiber. For the reverse direction, data comes into the transmitter via an optical receiver operating at a different
wavelength than the transmitter. The received data stream is demultiplexed into data for output via the data port
and the Option Module Ports.
The receiver accepts the optical signal and converts it back to a serial bit stream. The signal is deserialized and
converted back into the video and data signals, which are output on the BNC and data connectors. For the
reverse direction, outputs from the data port and the Option Module Ports are multiplexed together, converted
to an optical signal for transmission to the transmitter on the second wavelength.
The built-in data port is dipswitch-programmable. The port may be configured for Manchester-encoded data,
RS485-2-wire, RS485 4-wire, RS422, or RS232. The data port supports data at speeds up to 115.2 kbps.
The 9245DT and 9245DR support two TKH Security USA Data/Audio Option Modules. The modules operate
bidirectionally. The user may select from duplex audio (Option Module type A), duplex data (Option Module type
B), duplex contact closure (Option Module type C) or Stereo Audio (Option Module type D, Stereo Input, and E,
Stereo Output).
The Xs in the 9245DT(XX)-Y-ZZ and 9245DR(XX)-Y-ZZ model numbers should be replaced with the letter for the
type of Option Module desired. The specific Option Modules installed are indicated by labels on the front panel
and on the AUX I/O connectors.
The 9245DT and 9245DR are optically compatible with the 9241DT and 9241DR rack-mount card models.
The 9245D module has been evaluated with TKH Security USA external power adapter Model 9014 with input at
110 VAC, 60 Hz, and with TKH Security USA external power adapter Model 9011 with input between 100 and 240
VAC, 50 to 60 Hz. These power adapters are suitable for use at a temperature above 0° C, up to 40° C. The TKH
Security USA PSR adapter may be used between –10° C and +60° C. If the module is to be used in an ambient
outside this ambient temperature range, a power source must be used that is suitable for use at that ambient and
additional evaluation of the module may be required in the end product.

Troubleshooting 9245D Links
The sync indicator LED on the transmitter and receiver provide information as to the optical and electrical
status of the units. Troubleshooting normally starts at the transmitting end.
The SYNC LED serves multiple functions:
 OFF indicates no power is applied to the unit. Check the power connections and source.
 Red (NO SYNC, NO LOOP) indicates the local unit is not receiving sufficient optical signal from the remote
unit or the local demux circuitry is not able to synchronize to the incoming signal. Check the fiber for poor
connections or optical losses greater than the unit specifications.
 Yellow (SYNC, NO LOOP) indicates the local unit has synchronized to the incoming signal, but the remote
unit has not synchronized with the local unit. Check the fiber for poor connections or optical losses greater
than the unit specifications.
 Green (SYNC, LOOP) indicates that both local and remote units are communicating correctly.
