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

Functional Description
The 9421DT transmitter accepts two composite video signals in NTSC, PAL, or SECAM format via two BNC video
input ports. The baseband video signals are each sampled at a 16 Mhz rate by an A-to-D converter operating with
nine bits of precision. The signals are multiplexed, serialized along with the serial data from the option modules
and the high-speed port, and converted to an optical signal for transmission over the 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 Option Modules and high-speed
port.
The 9421DR receiver accepts the optical signal and demultiplexes it into bit streams for the video and the data.
The video stream signal is deserialized and converted back into the video signals, which are output at the BNC
connectors. The data stream is demultiplexed and sent to the Option Modules and high-speed Port. For the
reverse direction, outputs from the Option modules and high-speed Port are multiplexed together and converted to
an optical signal for transmission to the transmitter on the second wavelength.
The 9421DT and DR 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 9421DT(XX)-Y-ZZ and 9421DR(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 high-speed port operates in both directions. It provides a simplex 16 MB synchronous or 1.6 MB
asynchronous RS422 port. This port is designed to operate with the 9961-C or 9962-C Option Module Host
cards or the 9971-C high-speed port to 10 Base T Ethernet card. The 9961-C and 9962-C cards add data,
audio, and contact closure channels. The 9971-C card has two user-programmable serial data ports and one
Full or Half Duplex 10 Base T Ethernet Link.
9421DT and DR cards are optically compatible with the 9425DT and 9425DR stand-alone models.
The cards operate on 6VDC as supplied by the chassis into which it is installed.

HIGH SPEED PORT OPERATION
The high-speed port is a 16 Mbps simplex synchronous RS422 port. The port may be used synchronously at a
speed of 16 MB and asynchronously at up to 1.6 Mbps. It may be used as an RS422 port or to interface directly
with the 9961-C or 9962-C Option Module Host Cards.
The 9961-C and 9962-C provide any combination of four or eight duplex audio, data, contact closure, or stereo
audio channels. This is in addition to the video and the two Option Module channels already built into the 9401DT
and DR cards.
The 9971-C High-Speed Port to 10 Base T Ethernet Card provides two duplex serial ports and one 10 Base T
Ethernet Link via the high-speed port.
The ports are wired as shown in Figure 3 and in Table 1. The 9961-C, 9962-C, and 9971-C cards are normally
supplied with a properly configured cable for connection to the high-speed port. A standard (not crossover) RJ45
CAT5 cable will also work correctly.

Troubleshooting 9421D Links
The indicator LEDs on the transmitter and receiver provide information as to the optical and electrical status of
the units. Troubleshooting normally starts at the transmitting end.
On the 9421DT and 9421DR cards, the sync indicator should be illuminated with one of three colors. If it is not
illuminated, check the chassis power supply, power source, and connections.
When the SYNC indicator is illuminated green ,operation is normal. When the SYNC is illuminated red , this is
usually an indication of insufficient optical signal at the optical input. Check the fiber for poor connections or
optical losses greater than the unit specifications.
If the SYNC indicator is yellow , the local unit is in sync and the remote unit is not. This usually means that there
is an optical loss problem in one direction from the local unit to the remote. Again, check the fiber for bends or
check the optical link for excessive losses.
Since this unit uses two wavelengths, the losses for each one can be different. Each wavelength reacts
differently to bends and splices as well.
When video is connected to Channel 1 or Channel 2 input BNCs, the Video Present indicator for that channel
should be illuminated green. If the Video Present indicator is not green, then check the video source and
connections.
IF both STATUS indicators are illuminated green and the TX Video Present indicator is not illuminated, the video
source at the transmitter end should be checked.
