2 Introduction
The PMC (Media Converter, hereinafter called PMC100-1/ PMC100-2) modules which include
models that utilize new built-in IP camera device or are capable of upgrading analog camera into
IP camera, are ideal devices for centralized surveillance and control. Furthermore, its
installation cost is cut to minimum due to reduced installation man-hour and cable/wiring
requirements. Through splitter, the PMC modules can be connected to the security network
through existing coaxial cables or telephone wirings. PMC modules are also capable of
extending its surveillance capability to about 1.5 kilometer from control center through a single
Ethernet port (RJ-45) and an RJ-11or wire terminal block port.
PMC modules are plug-n-play as they do not require software. For long range connections, the
modules offer up to 100/60 Mbps transition bandwidth for the distance of within 300 meters and
25/5 Mbps for 1.6 kilometers using existing telephone line at ultra-high performance. Being a
plug-n-play device, it provides minimum installation time as well as minimum expense by
allowing video streaming and data sharing with existing telephone twisted-pair or coaxial cable
without interference.
With its ultra-high performance, the PMC modules are capable of transmitting high definition
images; such as High Definition Television (HDTV). This makes the device most suitable for
hotel/motel rooms TV network application. PMC modules also support Ethernet Bridge and
switching functions and are compatible with optical fiber device.
In suppressing radio interference in tunnel or elevator, as well as in long distance surveillance in
farmlands or of bridges across bays, the PMC modules are capable of meeting these challenges
as long as telephone line or cable networks already exist in these locations. Furthermore, the
modules are also equipped with RS485 interfaces for Emergency/Security Control application.
Lastly, PMC modules feature the Remote Power Feeding (RPF) capability that enables the
device to transmit and provide power over telephone lines. This is an ideal option for applying
surveillance network in remote areas where power source is not available.

User’s Manual
This case shows user installing a new surveillance IP camera using the existing coaxial cable
which is connected and used by an analog camera. Therefore, no fresh wiring is involved and
cost down is achieved
As user wants to add a new IP camera in addition to the existed analog camera, it is therefore
necessary to use a coaxial splitter device. Furthermore, user must add a modulator device
between analog cameras and coaxial splitter, and add a demodulator device between coaxial
splitter and surveillance center device. If user wants to add more new IP cameras, it only needs
to install a switch hub device between IP cameras and PMC100-2.
> Theory:
IP camera delivers image data through RJ-45 line. Analog camera delivers image data through
coaxial cable line. We use modulator/demodulator devices to separate a high frequency or low
frequency from the same frequency band.

6 Q&A
Q1. How to select CO side and CPE side mode PMC?
A1. Referring to the figure below, the PMC B module (nearest to IP camera) is the CO side and
PMC A module (nearest to control center) is the CPE side for valid operation bandwidth.
Q2. How to identify fast and interleaved mode?
A2. Fast mode guarantees a minimum end to end latency of less than 1 ms. Interleaved mode
provides protection from any impulse noise with duration of less than 250 μs. Interleaved mode
has a maximum end to end latency of 10 ms. Interleaved mode is the default mode.
Q3. How to select target data rate and target SNR margin?
A3. User can select fixed SNR margin (9 dB) or fixed target data rate. When fixed SNR margin
is selected, the systems will maintain the SNR margin at 9 dB across all usable loop length.
When fixed target data rate is selected, the system will lock the data rate at 50Mbps/30Mbps
whenever the calculated SNR margin is higher than 9 dB. This provides the best system
stability and is the default mode.
Q4. Why PMC modules cannot link each other after training?
A4. 1) A pair of PMC modules should consist of a CO side mode module and a CPE
side mode module. They cannot be of the same mode modules.
2) RJ-11 jack and connector may have loose contact.
3) The distance between 2 PMC modules should not exceed 1.5Km.
