2 . 2 Modem Installation
This chapter describes the panel function and installation procedure for the
TD-5612DCII.
A shielded RS-232 cable is required to ensure compliance with FCC Part 15, and
it is your responsibility to use a shielded RS-232 cable. Make sure your
installation site is clean and well ventilated. The ventilation slot of your
modem located on the sides and bottom should not be covered to allow for free
movement of air.

2 . 3 The LED Indicators on the Front Panel
The indicators on the modem's front panel denote the current modem operation
characteristics and status. They are:
LED
MR(Modem Ready)
TR(Terminal Ready)
SD(Send Data)
RD(Receive Data)
OH(Off-Hook)
CD(Carrier Detected)
AA(Auto-Answer)
HS(High Speed)
Lights up when the modem is turned on.
Flashes when DTR signal is detected.
Flashes when the modem is sending data to the remote modem or
when receiving data from the local computer.
Lights up when a carrier from the remote modem is detected.
Lights up when the modem is using the telephone line. Off when
the modem hangs-up(on-hook).
Lights up when a carrier from the remote modem is detected.
Lights up when the modem is set for auto-answer. Flashes when an
incoming ring is detected.
Lights up when modem speed exceeds 4800bps.
Function
When you turn on your modem, at least the MR indicator shall light up. There
may be some other indictors lights depended on the settlement of the modem.
Otherwise, you should check the power connected to your modem.

Chapter 2 UNPACKING AND INSTALLATION
2.5 The Serial Port and the RS-232 Cable
To use this modem, it will require an RS-232 serial port on your computer. If your
do not have it, you need to have one.
It is better to select a serial port card that uses a high-speed 16550 UART chip. A
card with an ordinary UART chip handles transmissions at a maximum speed
around 38,400bps. In case the data compression of your modem is active, it may
perform at an exceeding speed and an ordinary serial port card may sometimes
cause data loss.
You will also require an RS-232 cable to connect your modem with computer. You
will be Asked to buy a modem cable if you are a PC user. The modem cable shall,
at one end, have a DB25M (male) connector that fits the female connector on the
modem, and at the other end a serial port connector that matches your computer.
2.6 Hardware Connection
1) Make sure that both the modem and computer are turned off.
2) Use an RS-232 cable to connect the modem to a serial port on your computer.
Secure the connector screw on it.
Verify the serial port number in which your modem is connected. You must
Write down the port number as you will need to specify this number during
software installation. As a general rule on PC applications, the port COM1 is
connected to a mouse, while COM2 is for a modem.
3) Use an RJ-11 cable to connect the LINE jack to the wall outlet of the
telephone line.
4) Connect a telephone set to the PHONE jack. You may leave this jack
disconnected if desired.
5) Make sure that the power adapter that comes with your modem is of a correct
voltage that complies with your power source. Use the adapter to connect the
power source to the POWER jack one the modem.
2.7 Test the Power connection
You can turn on your modem by pushing the power switch button and watch the
front panel indicators. Depending on the setting of your modem, the MR and other
indicators should light up. If none is lit, check the power connection for the
modem.

Chapter 2 UNPACKING AND INSTALLATION
2.8 Test the Telephone Line Connection
Once a telephone set is connected, you may test the line quality and connections
by lifting the telephone handset, listening for a clear dial tone, and making several
telephone calls. The calls should go through well and the sound loud and clear.
Otherwise, the line may be poor or have a faulty connection.
2.9 Data Communications Software Packages
Your modem follows the industrial standard in the modem command set. As a
result, most of the popular communications software packages off-the-shelf will
work with it. You should select a software package according to your application
requirement.
Most popular communications software are provided with the configuration
named Initial-String or Dialing-Prefix. It is wise to check, one by one, the
commands in this string as they will be sent to determine the modem
characteristics each time prior to dialing.
2.10 Fax communications Software Packages
Similar to data communication applications, you interact with the modem through
the fax communications software.
Your modem supports Class 1& Class 1.0 command set.
2.11 Error-Correction and Data compression
Your modem supports the industrial standards of V.42 LAPM MNP 2-4 and
V.44 V.42bis MNP 5 for error-correction and data compression (ECDC).
、 、
Both standards are capable of error-correction as well. The modem will retransmit a faulty data block when an error is detected while receiving.
、
2.12 Installation of Modem Driver in Win owsXPd
1. Windows XP "Found New Hardware Wizard". Please tick "Install from a list or
specific location", and then go to next step.
