1. Safety and operating instructions
When assembling, starting-up and adjusting the modules, it is necessary to consider the system specific references in
the manual instruction!
The modules may only be installed and started up by authorized technical personnel!
When assembling the modules into the receiving points, the adherence of the EMC regulations is to be secured!
The assembly and wiring have to be done without voltage!
With all work the defaults of the DIN EN 50083 have to be considered! Especially the safety relevant execution of the
DIN EN 60728-11 [3] is necessary!
The devices come under protection classification I. It is absolutely necessary, therefore, to insert the mains plug into a
socket with protective contact.

3. General
The QAM Modulator AMA 299 is a module of the head end system A-LINE which is conceived as a complete system for big and
middle-sized networks.The module converts one digital transponder into the digital cable standard DVB-C, ITU-T J.83 Annex B or C.
The signal will be transcoded from the ASI transport stream into cable TV channels.
The status of the assembly will displayed with LEDs (see section 5.2 ”Meaning of the LED signals”).
4. Function description
The data stream which results from the ASI input is passed to a FIFO. All services of the resulting transport stream which shall be
processed into the QAM modulator will be choosen by controling software of the module. The SI and PSI tables affected (i.e. the PAT,
PMT, SDT, EIT, NIT) are automatically corrected. The changed SI an PSI tables are fed into the QAM modulator and an IF signal is generated at the output channel. There is a free choise of frequency in the output channel from 45 to 862 MHz. On the output side, the
modulator does not leak to adjacent channels. For level error reporting a reference level is generated internally and is compared with
current value permanently. After each programming of the level and/or frequency values an automatic measurement of the reference
level takes place. The integrated management unit consists of the data interface for PC/LAN/WAN (IP/Ethernet - interface / RJ 45). The
management of the module can be done via PC/Laptop (see programming).
The IP address of each device can be edited and adjusted to the respective LAN.

By activating the ESCAPE-Pad you exit the current menu cycle. The input function switches back to the inactive status and jumps to the status information (Start display)
By activating the BACK-Pad you leave the current mode (Menu selection) without any acceptance of settings
or adjustments. The cursor jumps one menu level higher.
Pressing of the tuning wheel is equivalent to the ENTER-Function.
The cursor switches to the active mode. Tuning the wheel right or left enables to select an menu entry, the
menu selection will be confirmed by pressing the wheel.
Each parameter function can be edited by pressing the tuning wheel (ENTER). By tuning the wheel you can
position the cursor to the desired selection. By pressing the tuning wheel (ENTER) you switch to the Editmode. The text- and/or number positions can be individually selected by tuning the wheel. Pressing the wheel
(ENTER) confirms your input and switches back to the selection mode. After a complete and correct adjustment you have to position the cursor right to the symbol ↵ ENTER and confirm it by pressing the tuning
wheel. The display switches back to the selection mode of the parameter display!

6.1 Network connection to computer
System requirements:
- PC/Laptop with 10/100 Mbit Ethernet interface
- Internet browser (e.g. Windows Internet Explorer), which accept
JAVA-Script.
Setup the connection:
The AMA 299 must be connected to PC Network using an Ethernet cable.
The IP address of the AMA 299 control port is 192.168.2.80 on delivery.
The address of the network connection at the compter must be adapted to
the IP address of the AMA 299 (subnet mask: 255.255.255.0, IP address:
192.168.2.XXX). Don`t be use the same combination lock for XXX like the
IP address of the AMA 299. The IP address of the AMA 299 is entered onto
the browser interface.
When the link up has been successfully made, the device starts with the
device status page.
The language (english/ german) can be selected on the right side of each
page. To change the settings of the device at the first user log-in window
will be open automatically.
The access to the configuration menu is password protected.
Access data (factory settings):

After successful log-in the parameters can be modified.
The user log-in is only temporarily. The connection has to be refreshed
after some time.
