Chapter 1 Product Outline

1.1 Outlines

FUTV4440B 4 in 1 QAM is a cost effective integrated QAM modulator newly designed by FMUSER Company. This device is integrated up to 4 channel QAM modulating carrier outputs, in which each carrier has independent signal channel encoding and direct RF output. Therefore, the device is featured with excellent RF performance index. It supports 4 channel ASI inputs (4 QAM (J.83 A/B/C), 4 DVB-S tuner input or 4 DVB-S2 tuner input). Alternatively, this device can take various RF inputs of DVB-S/DVB-C/DVB-S2 signals by installing the relevant build-in tuners. Hence, one PCS 4 in 1 QAM modulator can work as 4 standalone QAM modulators, significantly reducing the

Press “Constellation” to enter the QAM modulation mode selection, ENTER to the specified setting. The display shows as below:

There possible options are different according to the different modulate standard set in 1.2. (J.83A/DVB-C: 16QAM, 32QAM, 64QAM, 128QAM and 256QAM; J.83B: 64QAM and 256QAM; J.83C: 64QAM and 256QAM). User can press ENTER and move UP/DOWN key to choose the constellation as needed, and then repress ENETER after modification to confirm. Note: The more advanced QAM constellation mode, the higher transmission efficiency and TS coding rate which the device can

transport at the same symbol rate. Accordingly, with the TS coding rate increasing, the signals’ anti-jamming capability will become weaker. Hence, those wired network currently in effect usually adopt QAM modulation mode no exceeding 64QAM. What needs to be pointed out is, the effective coding rate this modulator can transport is limitary when the device works as different constellations and symbol rates. User can refer to the formula as below: Max_input_bitrate = Symb_rate*qam_bits*188/204 Max input bit rate: the maximum effective inputting coding rate Symb rate: the symbol rate Qam_bits: the QAM bit when device works as current constellation (user can refer to the following table when device works as 6.875Msps symbol rate):

Chapter 5 NMS Setting

Network Management System Profile

Network management system is applied to digital TV equipment operation, control and management and parameters setting, etc. It centralizes digital TV equipment through network.

5.1 Installation

Both NMS (based on UDP protocol) and SNMP (based on SNMP protocol) can be applied to manage the device. The software doesn’t need special installation. User can just copy “Network Management Software X.XXY.exe” to the specified directory (X.XX is version number, Y represents language. For example: the version number of network management software 4.01E.exe is

4.01 English version) or place different versions of network management software to the same directory. When the network management software is running, it will generate two documents as follows: Network management software X.XXY.log (It preserves the log file.) Info. Bin (It’s the user configuration data.)

5.2 Software Operation

5.2.1 Login Interface

A login interface will pop up firstly when the software is running and

give user prompts to input user name and password, the menu shows as follows:

User can login the NMS by pressing Confirm key after inputting user name and password. Upon the inputs, the software will verify them with database record automatically. If both of them are correct, the main interface will appear. Both of the default user name and password are admin. (If the SNMP is applied, the default user name is admin, while no password needed.)

5.2.2 Main Interface

5.3.1.2.6 Outgain (refer to 4.2.2.5)

Total output level attenuation

User can see following description about start frequency:

The RF output frequency range is from 30MHz to 960MHz. Here the start frequency, namely actually, user often say the centre frequency of TS output. Therefore, user can only set the start frequency from 30MHz to 960MHz (considering the 6/8MHz bandwidth optional). Note: the start frequency discussed here means centre frequency The display shows as below:

5.3.3 TS Locked/Overflow

User can refer to the formula Max_input_bitrate = Symb_rate*qam_bits*188/204 to estimate whether the effective bit rate is above on the maximum value. If the input bit rate is exceeding, the over flow indicator will be light on.

5.3.4 Effective bit rate

User can also refer to the maximum bit rate formula and table. The current setting is 64 QAM constellations with 6.875Mbps symbol rate, so the maximum bit rate should be

6.875Msps*6*188/204≈38.015Mbps. Here user can see the current

Green: TS Locked

Red: TS overflow

Grey: TS Loss

Grey: TS doesn’t overflow

input bit rate each channel is about 33.33, which can be named effective bit rate.

5.3.5 Output level attenuation

The level attenuation for each channel equals to RF general out gain pluses channel gain. The illustration shows as below:

Note: For each channel, its out gain equals to the general out gain (circled by red line) pluses the respective out gain (circled by blue line). For example, the channel 1 out gain in above illustration=-16+ (-12) = -28(db)
