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 9152DT Multiplexer/Transmitter combines eight composite video baseband signals by
implementing a 10-bit linear analog-to-digital conversion on each signal at a 15 MHz rate, combining the
signals with five input data signals using Time Division Multiplexing (TDM) techniques and transmitting the
data via one optical fiber.
The Model 9152DR receives the optical signal from the transmitter, separates the composite data into eight
digital video data streams and five data streams, does an digital-to-analog conversion of the eight video data
streams yielding eight composite video outputs and five data outputs.
The 9152DT and 9152DR are compatible with the 9000 series card chassis, occupies two card slots each, and
operate on 6 VDC from the appropriate chassis power supply.

3. VIDEO INPUT CONNECTORS (EIGHT)
Compatible with BNC connected coaxial cables, these connectors accept the eight video input signals.
4. SIMPLEX DATA INPUT CONNECTORS (TWO)

B. The RJ12 “RS485” port accepts the input of an RS485-compatible data signal.
5. SIMPLEX HS AUX DATA INPUT PORTS
Each of these two RJ45 ports interface with a Model 9961-C or 9962-C Option Module Mux/Demux,
providing for the transmission of its composite data output signal via the 9152DT to the 9152DR. By using
up to two Model 9962-C Option Modules connected via the HS ports, up to 32 channels of audio or up to
16 channels of data may be transmitted in addition to the 8 video channels over the same optical fiber.
The shielded Cat5/6e cable connecting the two HS Aux Data ports should not exceed 4 feet (1.3m).
6. DATA INTERFACE CONFIGURATION DIPSWITCH
This ten-position dipswitch allows the user to select the desired data interface compatibility of the

from the HS AUX Data Input Ports. These high-speed ports greatly expand the transmission capability of
the 9152DT/9152DR pair. The shielded Cat5/6e cable connecting the two HS Aux Data ports should not
exceed 4 feet (1.3m).

To install, connect the video inputs to the 9152DT, connect the video monitors or other video receptors to
the 9152DR, and connect an appropriate optical fiber between the 9152DT and 9152DR optical ports.
Connect data signal sources or destinations, as required, to the “DATA” and “RS485” ports per the
following Built-In Data Connection section. If the Model 9961-C or 9962-C add-on option interface module
mux/demux host units are to be used, plug the CAT-5/6e data cable from the unit(s) into the HS AUX data
port(s) as required. The shielded Cat5/6e cable connecting the HS Data ports to accessory cards should not
exceed 4 feet (1.3m) in length.

Built-In Data Connection and Configuration
DATA AND RS485 PORTS
There are four data interface ports on the 9152DT and 9152DR. Two of them are the
“
DATA” port and the
“RS485” port that are primarily used for the transmission of RS232, RS422, RS485 or Manchester (biphase)
PTZ data.
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 terminations should be enabled (ON) and when it should be disabled (OFF).
The “RS485” port supports a dedicated 2-wire RS485 channel. The only dipswitch setting required for this
port is the termination setup. Tables 1 (above) and 3 contain switch setting and pinout information.
Connection information is found in Figures 8 and 9. Refer to the next section on Termination Rules to
determine when the terminations should be enabled (ON) and when it should be disabled (OFF).

RS485, RS422, AND MANCHESTERTERMINATION 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.
The following diagrams show examples of various system connections.

HS AUX DATA PORTS
In addition to the “DATA” and “RS485” ports on both the DT and DR units, there are two HS AUX DATA
INPUT ports on the 9152DT and two HS AUX DATA OUTPUT ports on the 9152DR. Each of these ports is
capable of carrying asynchronous RS422 data at rates from DC to 1.5 Mbps (10X oversampled) in one
direction from the transmitter (9152DT) to the receiver (9152DR). These ports can carry synchronous data
utilizing the 15 MHz Transmit Clock and Receive Clock outputs provided.
Although these ports can be used for general purpose RS422 applications, they are primarily configured to
support the Model 9961-C Four Channel and 9962-C Eight Channel Auxiliary Data/Audio Mux/Demux Cards.
When mated with the host Model 9152D units, these cards operate in simplex mode supporting either four
or eight Data/Audio Option Modules. To install, connect a straight through Category 5 jumper cable (provided
with the 996X-C) from the 9961-C or 9962-C to either of the HS AUX DATA PORTS on both the 9152DT and
9152DR. This provides the separate mux/demux card access to the significant data transmission capability of
the 9152DT/DR to transport its data without using extra optical fibers. The shielded Cat5/6e cable used
should not exceed 4 feet (1.3m).

Operation of the 9152DT and 9152DR
Operation is straightforward. Connect per the directions in the Configuration and Connection Guide section
on page 5. There are no adjustments. Under normal operation, only the green POWER indicator on the
9152DT and the green SYNC indicator on the 9152DR will be illuminated.
