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: 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
Pure isopropanol is very flammable!
) 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 9482DT transmitter accepts four composite video signals in NTSC or PAL format via four BNC video input ports. The baseband video signals are each sampled at a 15 Mhz rate by an A-to-D converter operating with nine bits of precision. The resulting digital signals are multiplexed and serialized along with the serial data from the two data ports and the high-speed port and converted to an optical signal for transmission over the fiber. The control and data signals from the receiver end arrive via an optical receiver operating at a different wavelength on the same fiber. The optical signal is converted back into a serial bit stream and demultiplexed into data signals for the two data ports, the duplex high-speed port, and for the “up-the-coax” control signals.
The “up-the-coax” control signals are synchronized with the incoming video signals for output on the input
BNC connectors.
The 9482DR receiver accepts the optical signal from the transmitter and demultiplexes it into serial bit streams for the video and the data. The video stream signal is converted back into four video signals that are output at the BNC connectors. The data stream is demultiplexed and routed to the two data ports and the high-speed port. Data input to the two data ports and the high-speed port is multiplexed together with the “up-the-coax” control data that is input from the video output BNCs, serialized, and converted to an optical signal for transport to the transmitter on the second wavelength.
The high-speed port provides a duplex 15 MB synchronous RS422 port. The port may be used as a 4-wire 1.5
Mbps asynchronous RS422 port; however, its primary purpose is to support optional accessory cards.
Currently, the port supports the 9961-C/9961A-C and 9962-C/9962A-C Option Module Host cards, the 9971-C
High-Speed Port to 10 Mb Ethernet Card with data ports, and the 9973-C High-Speed Port to 10 Base T 4-Port
Ethernet Switch card. Contact the factory to determine if there are other accessory cards available that will operate on high-speed ports. RJ45 Cat5 cable used to connect the High-Speed port may not exceed 1.3 meters (4 feet) in length.
The 9482D cards operate on 6VDC as supplied by the chassis into which they are installed.

Data ports can be wired as shown in the following examples. Many different manufacturers of equipment mark their terminals differently. The data ports on one end of the link may be set to a different data type than the opposite end. For example, the Receiver end may be set for RS232 to communicate with a PC type computer port and the opposite end of that data link may be set to RS422 or RS485. No external data conversion units would be required.
RS232
RS232 is a “point-to-point” or “one-to-one” connection allowing only one transmitter and one receiver per electrical link. Care should be taken to insure that the Tx or transmitting end on one end of the electrical link is connected to a receiver or Rx signal on the other. Depending on whether the devices are Data
Communications Equipment (DCE) or Data Terminal Equipment (DTE), the Tx and Rx marking will change.
The 9482D RS232 terminals are called Tx (an output) and Rx (an input).
RS422
AND
RS485
RS422 simplex is a “one-to-many” or “daisy chain” connection allowing up to 10 receivers to be electrically connected to one transmitter. Markings on RS422 devices vary, with Tx+, Rx+, Tx–, and Rx– being common, as well as TA, TB, RA, and RB. Normally the TA and RA signals are the – signals, with T being an output and
R being an input. The TB and RB signals are the + signals. The termination resistors on the last receiving device in the electrical daisy chain of receivers should have its termination resistors turned on. Refer to the example drawings at the end of this section for examples.
RS422 duplex is a one-to-one connection. In RS422 duplex, you are limited to one transmitter at each end of the link. This is because to connect more than two transmitting devices on one electrical link in RS422 is not allowed. Markings on RS422 devices vary with TX+, RX+, TX–, and RX– being common, as well as TA, TB, RA, and RB. Normally the TA and RA signals are the – signals, with T being an output and R being an input. The termination devices on both ends of the link should be enabled.
15
RS485 duplex 2- and 4-wire can be configured as “one- to-one“ or “one-to-many” as RS485 systems allow up to 32 devices to be daisy-chained together in one electrical system. Markings on RS485 devices vary, sometimes being marked the same as RS422 systems in 4-wire connection modes or marked as TD+, RD+,
TD–, and RD–. Normally the A and – signals are the – signals and the B or + signals are the + signals. In
2wire systems, there will only be a + and – signal. Care should be taken to insure the last device in a daisy chain is terminated. Refer to the example drawings at the end of this section for examples.
Many manufacturers mark their equipment differently; read the accompanying instructions
carefully. A misunderstanding of the terminal markings and functions on data communications devices causes most problems with data connections.
G
ROUNDING AND
S
HIELDS
The common ground/signal ground on the TKH Security USA equipment is also chassis ground. The ground connection is required on both ends of an electrical connection when RS232 is used. Both the Tx (the output) and Rx (the input) signals are single-ended connections (unbalanced) and are referenced to signal common.
In RS422 and RS485, the shield wire in the cable is to protect the cable from noise and electrical interference; the + and – signals on the cable are differential (balanced) and do not require the ground be connected at both ends. It is generally accepted practice to connect them both, however, better noise immunity may be obtained by connecting the shield only at the end closest to true earth ground. This may also eliminate ground loop electrical problems as well. If noise problems are encountered in a data transmission system when RS422 or RS485 are used, try disconnecting the shield at the camera end of the data link.

NMS users should set the Alarm Status and Alarm Limits for each parameter as required for the specific application when the NMS software is operated for the first time.
When the 9482D card is installed into an existing system already utilizing NMS system software, an upgrade of the software will be necessary to add the 9482D card to the software database in the NMS software.
Consult the factory for guidance on how to download the latest version of the software from the TKH Security
