7. Run the PC SW programming.
| Important note:
Connect the power supply to the PC before running the software so that it is correctly detected by the PC driver.
“CM Management” PROGRAMMING SOFTWARE:
The “CM Management” programming software enables programming and controlling
the CM COMPACT 8S8. The program is only available for Windows operating
systems (version XP, 7 and higher). Once downloaded from the website
www.ek.plus, Software/CM Headend section, run the
program after connecting the PC to the USB port. This will ensure that the
driver detects the unit
Main screen:
The main screen of the “CM Management” software is displayed as
follows:
Always check that the latest software version from our WEBSITE is installed. By clicking on the “green and blue” colored square, the main configuration screen of the CM COMPACT 8S8 unit is displayed in the “INPUTS” tab:
Using the “CM Management” software, the module connected to the PC can be controlled and programmed. The function of each of the main side options is explained below:
The main “CM Management” screen enables easy identification of the connected module, as can be seen in the following screen:
|
1. Power supply and system manager. (Red box).
2. Unit identification (Green and blue box)

Inputs: Satellite input:
Select from A to H, the input tuner which are wished to be configured:
-
Enabled: Enables or disables the selected physical input. (IN1 – IN2 – IN3 – IN4). It is important to DISABLE the inputs which are not used, disabling the Enabled check.

-
Standard: Option not available.
-
Biss Freq. (MHz): Frequency of the MUX to be tuned. The program uses IF (Intermediate Frequency), but carries out the conversion automatically if the frequency in MHZ is added.
Example: If 11496Mhz., is entered, once the last number is pressed, 1746 will automatically appear. Calculation: 11496 – 9750 = 1746. -

- Root: Type of root code. Enter the code in the
- Gold: Gold code type. Enter the code in the
-
Sub stream ID: Enter the stream associated with the selected MUX.

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 output MUX can be selected. Each service is assigned to the input tuner from which it has been tuned.
- S. Id.: S.ID. (Service Identification) assigned at source to that service.
- Name: 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.
- CI.: This module does not have a CI card.
- OUTPUT: MODULATIONN: each circle corresponds to a MUX output: 1, 2, 3, 4, 5, 6, 7 or 8. By clicking on the circle, it changes from red to green, and this service is assigned to a MUX output.
- Outputs: Output modulation.
DVB-T output card:
- Version: N.I.T. version
- Network ID: Original Network Identification Descriptor.
- Network name : Network name: Identifies the name of the local DVB-T (Digital Terrestrial Television) network.
- Orig net. ID: Network Identification Descriptor.
- L.C.N. ID: Logical Channel Number. LCN type selection (EACEM for Europe, ITC for the United Kingdom, Nordig for Nordic countries or Australia)
- CAT/EMM Rem.: Transmission or deletion of EMM messages and CAT tables.
DVB-C output card:
For the DVB-C everything is the same as for 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 the module is changed, the unit must be reset from the power supply.
RF output channel parameters:
- T.S ID: Identifier of the T.S. In general, it is not necessary to modify the identifier.
- Freq. (MHz Center frequency of the first desired output channel. E.g. CH21=474000 The first output channel is selected and the next three are adjacent. CH22-CH23-CH24 The second group of channels function in the same manner, select the first channel and then the following three are adjacent. E.g. CH30=546000 > CH31-CH32-CH33 In total 8 channels in two groups of adjacent channels. (4+4)
- B.W.: Bandwidth of the output channel: 7MHz or 8MHz.
- Const. : Constellation. Select the desired output constellation: 64QAM, 16QAM, QPSK.
- F.E.C.: (Forward Error Correction). Select the error correction level: 7/8, 5/6, 3/4, 2/3, 1/2.
- Guard. Int.: Guard Interval: Select guard interval: 1/32, 1/16, 1/8, 1/4.
- Level: The output level of the modulator is >95dBuV; it can be adjusted 20dB by using this attenuator.
Status:
Once the parameters have been configured correctly, the signal will be
acquired and an approximate value of these parameters will be specified in
Power and C/N. The power in dBm and the quality in dB. CANNOT BECONSIDERED AS
A PROFESSIONAL MEASUREMENT.
Information window on each MUX output current:
Four bars are displayed corresponding to each MUX output. The green line
indicates the percentage of the channel occupied.The “Total bitrate” or bit
rate, indicates the total current being transmitted. It should not exceed
200Mb/s.It should not exceed 80% of the current, unless for services with
constant current
.Advanced configuration:
LCN Function: The transmodulator enables tagging the Transport Streams of
information so that the TV programs are displayed in order on the TV set, in
its program guide as specified from the headend. In this way, all TV sets with
the LCN function available will have the same content in each program number
on the TV set. Whilst 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 carry out the program number assignment, simply double-
click on the LCN column of the program to be modified and apply the number of
the desired position. Example:
Configuration
of SID and NSID parameters: The transmodulators enables a “remapping” of
the SID fields. This functionality will enable changing the content of a
program on the TV set, leaving that program on the same output channel of the
headend module, without requiring to retune the TV set. To do this, it is
necessary to activate the new program to be transmitted in the same NSID where
the previous one was being broadcast, by double clicking on the NSID column of
the program to be modified. Example:
FAQS
-
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 is the headend module not detected?
Plug the transformer into the power supply, and connect the output connector to the CM COMPACT. Then connect a USB cable to the PC and open the CM MANAGEMENT program. Press the USB button and it will be connected 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 headend, leaving the attenuator at 0dB in the CM Management, and adding an external attenuator at the headend output until the same attenuation is obtained. -
How many input STREAMS can be added to the unit?
The unit allows for a maximum of 8 Streams. -
How many output services can be added?
The permitted maximum is 56 services in total, between TV and Radio. -
The following message is displayed:
Stream from pid extraction: no more channel available. -
What needs to be done?
The unit allows for a maximum of 8 Streams. A stream must be removed in order to be able to add another. -
Is there a button to save the configuration?
The unit does not have any save button per se; it is saved automatically. -
Can the configuration be exported and saved in a file on my PC?
Press the CM MANAGEMENT button extension and it will be saved in a file with the ‘.DTC’
