| Important note: If installing a head-end with several modules, always place the power supply to the left of the modules to be installed.
2.- Connect the power supply (FA 524) to the module or connect it to the previous module using the supplied power cable.

| The FA 55, power supply can also be used to power a single module.
3.- Connect the input signals to the transmodulator inputs.
| Important note: Pay particular attention to the input type and port. Follow the instructions on the front panel.
4.- Install the “CM Management” software on the PC. It can be downloaded from the website

https://ek.plus Software / CM Head-ends Section. Link

5.- To program the module, perform out any of the following connections:
5a.- PC – FA 524 programming via USB. Connect the FA 524 power supply to a PC using a USB (A) – USB (B) cable
5b.- PC – FA 524 programming via Ethernet. Connect the power supply and the PC via Ethernet cable, connect these on the same LAN (the power supply provided with the address 192.168.0.222). If it is necessary to be connected when not connected to the LAN itself, the CM KEY access key must be enabled beforehand.
5c.- PC – CM PR programming via USB. Connect the module to the device using the power and data cable. Connect the PC to the CM PR via USB cable.

6.- Run the PC SW programming.
| Important note: Connect the FA 524 power supply or the CM PR programming device and FA 55 power supply to the PC before running the software so that it is correctly detected by the PC driver.

Installation of a multi-module head-end:
In the event of wishing to install the module as a further element of a head- end consisting of other CM series modules it is very important to follow the instructions below.

Connect the different modules in series using the supplied power cable and then the power supply, which must always be to the left of the head-end.
Check the consumption of the modules. In general, up to 5 modules can be connected using an FA 524 power supply. However, it is recommended to check the power consumptions of the modules to be installed.
It is recommended to install the modules with CIs downstream of the power supply.
It is possible to use the long jumper to deliver the input signal to adjacent modules.
The attenuation at the output of each module can be adjusted to compensate for cable losses at high frequency.

“CM Management” PROGRAMMING SOFTWARE:

The “CM Management” programming software enables programming and controlling all CM head-end modules. The program is only available for Windows operating systems (version XP, 7 and higher). Once downloaded from the website https://ek.plus, Software / CM Head-end section, run the program after connecting the PC to the USB port of the FA 524 or CM PR power supply unit. This will ensure that the driver detects the control panel.

Main screen:
The main screen of the “CM Management” software is displayed as follows:

Always check that the latest WEB software version is installed. It can be directly connected via USB or LAN. For the LAN, select the equipment and for connection press: USB button

ID.: enter the MAC of the corresponding power supply.
KEY: enter the CM Key, if any. If not “0”.
LOCAL IP: the local IP will be entered if connected via LAN from the same network.
DESCRIPTION: description.

Using the “CM Management” software, all modules connected to the power supply can be controlled and programmed. The function of each of the main side options is explained below: EKSELANS-BY-IT-SCM-8SH-TC-DVB S-S2-TO-Cofdm-QAM-
Transmodulator-8

The main “CM Management” screen enables easy identification of the different modules connected to the power supply, as can be seen in the following screen:

| Power supply and head-end manager (red).

Identification of a module with an input card (green) and an output card (blue).

Identification of a module with only one input card (green), two CIs (orange) and one output card (blue).

Identification of a module with two input cards (green) and one output card (blue).

In this case it would be a power supply and three modules, each one with its different internal cards.

Program pool:

In this table all channels, services, which correspond to the selected entries will be listed. From here the services that are wished to be assigned to each MUX output can be selected. Each service is assigned to the input tuner from which it has been tuned.

S.I.D.: S.I.D. (Service Information Descriptor) assigned at source to that service.
Service name: name assigned to the service at source. Next, a symbol appears indicating whether the service is TV or Radio, and whether it is encrypted or open.
DECODIFIC.: This module does not have a CI card.
MODULATION: each circle corresponds to a MUX output: 1, 2, 3 or 4. By clicking on that circle, it changes from red to green, and this service is assigned to a MUX output.
DVB-T output card: This part of the menu consists of three differentiated sections:
- N.I.T. (Network Information Table) parameters
- RF output channel parameters
- Information window on the throughput of each MUX output

N. I.T. parameters:

Vers.: N.I.T. version.
O.N.I.D.: Original Network Identification Descriptor.
N.I.D.: Network Identification Descriptor.
L.C.N.: Logical Channel Number. LCN type selection (EACEM for Europe, ITC for the UK …)
Network Name identifies the name of the local DTT (Digital Terrestrial Television) network

RF output channel parameters:

Freq. (KHz): Center frequency, in KHz of the desired output channel. E.g. CH21=474000
Id. T.S.: T.S. identifier. In general, it is not necessary to change the identifier.
Const.: Constellation. Select the desired output constellation: 64QAM, 16QAM, QPSK.
Band: Output channel bandwidth: 7MHz or 8MHz.
F.E.C.: (Forward Error Correction). Select the error correction level: 7/8, 5/6, 3/4, 2/3, 1/2
Guard Int. Select guard interval: 1/32, 1/16, 1/8, 1/4.
Atten. Level: The power level of the modulator is 95dBuV; it can be adjusted 20dB by using this attenuator.

Information window on each MUX output throughput:
Four bars are displayed corresponding to each MUX output. The green line indicates the percentage of channel occupied. The number above indicates the total throughput being transmitted. At the end of each bar there are two numbers: the first number indicates the throughput being modulated on that channel and the second the maximum possible throughput for the selected modulation parameters. The first number should not exceed 80% of the second unless for services with constant throughput.

DVB-C output card:
For DVB-C it is all identical to the DVB-T except for the modulation parameters:

Const.: Select the desired output constellation: 256QAM, 128QAM, 64QAM, 16QAM.
Band: Output channel bandwidth: 7MHz or 8MHz.
S.R.: Enter the required value.
Whenever the modulation of a head-end module is changed, the power supply must be reset.

Advanced Configuration:

LCN Function:
The transmodulator enables labeling the information Transport Streams so that the TV programs are displayed in order on the TV set, in its program guide as specified from the head-end. In this way, all TV sets with the LCN function will have the same contents in each program number on the TV set. Although this function is useful for hotels or cable operators, as it avoids manual reordering of the programs on each TV set, tuning of each TV set is required. To perform the program number assignment, simply double-click on the LCN column of the program to be changed and apply the number of the desired position. Example: EKSELANS-BY-IT-SCM-8SH-TC-DVB S-S2-TO-Cofdm-QAM-
Transmodulator-13

Configuration of SID and NSID parameters:
The transmodulators enable a “remapping” of the SID fields. This functionality will enable to change the content of a program in the TV, leaving it in the same output channel of the head-end module, without the need to retune the TV. To do this, it is necessary to activate the new program to be transmitted in the same NSID where the previous program being broadcasted, by double clicking on the NSID column of the program to be changed. Example: EKSELANS-BY-IT-SCM-
8SH-TC-DVB S-S2-TO-Cofdm-QAM-Transmodulator-14

Flow: Adjustment of the data transfer rate to the output:
As a general rule, we will set the FTA (Free to Air) modules to 160Mbps.
Example flow calculation: 31668Mbps x 4 = 126672 Mbps – The value above would be 160 Mbps. EKSELANS-BY-IT-SCM-8SH-TC-DVB S-S2-TO-Cofdm-QAM-
Transmodulator-15

Remote head-end management:

The CM head-end can be managed remotely. This function is integrated in the FA 524 power supply and in each of the head-end modules. To do so, a CM KEY (082015 code) must be available. Each CM KEY is associated with a single power supply and will only enable remote management of that power supply. The installer will provide the Power Supply identifier to ITS Partner when requesting the CM KEY. Each installer company, in either event, will have a unique Software ID and Key which will be supplied together with the CM KEY . EKSELANS-BY-IT-SCM-8SH-TC-DVB S-S2-TO-Cofdm-QAM-

FAQS

What loads can be used for the module?
Use isolated loads CF 2150 A (163002) type
How many services can be installed on a MUX output?
It depends on the size of the channel selected in the “Program Pool”. For HD channels less channels can be installed than for SD channels.
Why does the head-end module not detect anything?
Set the FA 524 to the left. Connect the head-end module to the right. Plug the power to the FA 524, connect a USB cable to the PC and open the CM MANAGEMENT program.
Press the USB button and it will connect to the module.
Why is there no signal at the tuner input?
Check the orientation of the satellite dish and the LNB with the Metek.
If the MER (Modulation Error Rate) is located next to the power socket, can it be improved?
For installations where there are problems with the MER (Modulation Error Rate), an improved performance of the product can be obtained, in the event that it has been attenuated at the head-end, leaving the attenuator at 0dB in the CM Management, and adding an external attenuator at the head-end output until the same attenuation is obtained.
