Fiber Information
This unit was manufactured with attention to fiber cleanliness by Optelecom-NKF. 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. 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.

Functional Description
The Model 9172DT Multiplexer/Transmitter combines four composite video baseband signals by implementing
a 10-bit linear analog-to-digital conversion on each video signal at a 15 MHz rate/ This video data is multiplexed
with three to seven input data signals from the built-in data ports and audio/data option interface modules. All
of the multiplexed data is transmitted via one optical fiber.
The Model 9172DR receives the optical signal from the transmitter, separates the composite data into four
digital video data streams and three to seven data streams, and performs a digital-to-analog conversion of the
four video data streams yielding four composite video outputs and three data outputs via the built-in data
ports and up to four data or stereo audio outputs via the audio data option modules.
The 9172DT and 9172DR are compatible with and fit into the Series 9000 card chassis. They occupy two
card slots each and operate utilizing 6VDC from an appropriate power supply.

To install, connect the video inputs to the 9172DT, connect the video monitors or other video receptors to
the 9172DR, and connect an appropriate optical fiber between the 9172DT and 9172DR optical ports.
Connect data signal sources or destinations, as required, to the “DATA” and “RS485” ports per the
following Built-In Data Connection section. Connect data or audio sources and destination equipment per
the separate Audio/Data Option Module Installation and Operation Manual.

Built-In Data Connection and Configuration
There are two port interfaces on the 9172DT and 9172DR, the “ DATA” port and the “RS485” port.
The
“ DATA” port supports two data channels, one a full-time RS232 channel and the other a configurable data
channel that is dipswitch programmable for RS422, RS485 2- or 4-wire, or Manchester operation. Both
channels are implemented via the RJ45 connector marked
“ data”. The RS232 channel is a dedicated channel.
There are no dipswitch settings associated with or required for operation of this channel. The configurable
channel must be programmed by setting dipswitch S1 on the board for proper operation. Refer to Table 1 for
switch settings and to Table 2 and Figures 4, 5, 6, and 7 for connection and pinout information. Refer to the
section on termination to determine when the termination switches should be enabled (ON) and when they
should be disabled (OFF).

RS485, RS422, AND MANCHESTER TERMINATION RULES
For RS422, RS485, and Manchester connections it is possible that multiple devices may be connected in
parallel. This is usually a transmitter and many receivers connected together or many transceivers in RS485.
When this occurs, this parallel bus must be terminated with the correct impedance. Use the following rules
to determine if the termination resistors should be enabled or disabled.
RS422 and RS485
Enable termination only on the device farthest from the transmitting end, leaving the input termination
disabled on the devices in between.
Manchester
If there are six or more devices, disable all the termination resistors. If there are fewer than six devices,
enable termination only on the device farthest from the transmitting end, leaving the input termination
disabled on the devices in between.
