1 Safety Precautions
①
Please do not damage the DC power adaptor or plug.
② Please do not connect the cable connector at the back of the cable modem to the TV antenna
cable. Only connect to the CATV network providing the cable Internet service.
③ The cable modem should be located on a safe, flat surface in a space with plenty of
ventilation.
④ Please do not place electronic equipment or other objects on top of the cable modem.
⑤ Net&Sys will not be responsible for damage incurred by user mishandling or misuse, or
opening of the product case.
2 Box Contents
Please verify that the cable modem box contains the following.
Figure 1 MNG - 2000 Box Contents

2.1 Other Requirements
①
The cable modem requires a user PC running
Windows 95/98/NT/2000 supporting TCP/IP,
DHCP/BOOTP protocols
② The user PC needs to have an Ethernet 10/100 Base-T LAN card installed. The LAN card
maybe be purchased by the user or supplied by the Internet Service Provider.
3 MNG-2000 Cable Modem Front
The front of the MNG-2000 cable modem include five LED’s that are marked POWER, STATUS, UP,
DOWN and LAN. These are used in indicating the operating status of the cable modem.
Figure 2 MNG- 2000 Front View
3.1
POWER LED
When the DC adaptor plug is connected and power applied to the MNG-2000 cable modem, all
five LED’s will light up briefly before the POWER LED lights up. This indicates that power has
been correctly applied to the modem.
While the POWER LED lights up, the cable modem copies its operating program from the flash
memory to the dram memory. The LED will remain constantly on as long as power is applied.
3.2
STATUS LED
The STATUS led remains flashing while the modem is being initialized. After initialization is complete
and normal operation is possible, the STATUS LED remains green. The STATUS LED needs to
remain green in order for the Internet access to work properly.
After power is applied to the cable modem and its operating program is copied to DRAM, the modem
searches for the downstream channel.
3.3 UP LED
After the MNG-2000 cable modem as found the downstream channel, the DOWN LED will turn
green. During the time that data traffic is flowing through this downstream channel, the DOWN will
begin flashing.
3.4 DOWN LED
The MNG-2000 cable modem acquires upstream channel information from the downstream channel
and performs ranging in order to transmit data on the upstream channel properly. The UP LED will turn green
following completion of ranging and the modem is now ready transmit data. When transmit is in progress, the
UP LED will flash. If the upstream channel is lost, the UP LED will turn off.
Page 7
6
3.5 LAN LED
The LAN LED indicates the status of the link between the MNG-2000 cable modem and
computer. If the cable modem and computer is connected via the Ethernet cable, the LAN LED will
turn green. When data traffic between the cable modem and computer is active, the LAN LED will
flash green. If the cable modem and computer is not properly connected, the LAN LED will remain
off. In this case, please check the Ethernet cable or the Ethernet card inside the computer.

4 MNG-2000 Cable Modem Rear
The rear of the cable modem includes various connectors and switches. Some of the
connectors have been included to provide for additional functionality in the future and are not
currently being used.
Figure 3 Cable Modem Rear View
4.1 DC in Connector
This connector is used to supply the DC power to the cable modem and is connected to the
plug from the 7.5V DC adaptor. The modem will undergo the initialization routine described in
chapter 3 upon power on.
Please do not use a DC power adaptor other than that included in the original box. Using an
unknown adaptor may cause a serious damage to the cable modem.
4.2 USB Connector
Currently Ethernet is used to connect the cable modem to the computer. Optionally USB may
be used instead. The current MNG-2000 operating program does not support USB by default. The
program supporting USB will be provided optionally and available for upgrade on the current
modem. In this case, the computer will not require the LAN card but it will need a software driver
which will be provided on a floppy disk.
4.3 Ethernet Connector
The MNG-2000 cable modem and computer can be linked using the Ethernet cable included in
the box. This cable is a “direct” connected cable.
There are two types of Ethernet cables, “direct” and “cross”. The “cross” type cable can be
used to connect the modem and hub. The diagram below is a enlargement of the Ethernet
connectors.

4.4 Cable Connector
The cable connector is used to connect the RF coaxial cable from the CATV network to the
modem. The cable modem is connected to the ISP via this connector.
5 Cable Modem Installation
The figure below shows the rear of the MNG-2000 cable mo dem. The cable modem installation can
be setup as shown in figure 5.
Figure 5 Installation Setup

Each connector’s location is shown in Figure 3.
①
Connect the RF cable inside the home or office to the Cable connector.
②
Use the Ethernet cable included inside the box to connect the modem to the computer. The
computer must have a LAN installed with the proper LAN card driver installed on
Windows
95/98/NT/2000
③
Lastly, power up the modem by connecting the DC adaptor plug into the “DC in” jack of the modem.
You will be able to use your Internet within around 1.5 minuites.
m
If you are using USB optionally you have to install USB Network Driver at a PC. Refer Section 8.
After USB Network Driver at a PC is successfully installed, return back here and follow the next
procedure.
6 Cable Modem Inspection
In order to verify proper operation of the cable modem, the user must first inspect the LED status
and then verify that the computer as acquired IP correctly. The LED status is detailed in chapter 3.
6.1 Computer IP Address Verification
① Following proper operation of the cable modem based on LED indicators, the status of the
modem can be verified from the computer side as follows. From the desktop, select
[start]=>[run] and type “winipcfg”inside the popup window before clicking OK.
Figure 6 Run winipcfg program
Page 11
10
② From the IP Configuration popup window, select the correct Ethernet Adaptor.
Figure 7 Select Adaptor (LAN Card)
③ If the Ethernet adaptor’s IP is [0.0.0.0]
or
[169.X.X.X], the IP needs to be re-assigned for
proper Internet access. First, click [Release All] to release all previously assigned IP’s. The
IP Address should show either [0.0.0.0]
or
[169.X.X.X]. A new IP address will be assigned
after [Renew All] button is clicked.
④ If the IP does not change from [0.0.0.0]
or
[169.X.X.X] after the above procedure #3, there
are three possible reasons. Firstly, the cable modem may not be operating properly.
Secondly, LAN card may not be installed properly and thirdly, the server may be down.
⑤
In order to make sure that the cable modem may be the reason, it may be useful to unplug and then
re-connect the DC power from the modem and let it initialize again.
⑥ If the IP address is still not correct, select the menu [Start]=>[Settings]=>[Control
Panel]=>[System]=>[Device Manager]=>[Network Adaptors] and make sure that there is
no (!) in front of the LAN card. The (!) mark shows that the LAN card is not installed properly.
In this case, please try re-installing the LAN card after referring to the LAN card user’s
manual.
Page 12

Figure 8 Device Manager
⑦
If the IP address still cannot be acquired after procedures 5 & 6, please contact the
customer service center of your ISP.
6.2 Check Points for Modem Problems
① Please verify proper Ethernet connection between the modem and the computer.
If you are using UBS, please verify USB connection between the modem and the computer.
②
Please verify that the RF cable is properly connected to the cable modem.
③
Please verify proper installation of the computer OS, TCP/IP protocol and LAN card.
④ Please verify that the cable modem information(MAC address) is properly registered with
the ISP.
⑤
If the problem remains unresolved, please refer to this manual again or contact the
purchase company or store.
