SAFETY INSTRUCTION
Safety Technical Specifications
WARNING: Hot plug is not allowed since it may cause system failure.
To prevent fire or electrical shock,do not expose the device to rain or moisture.
The encoder modulator is powered with a voltage of 110 V to 240 V AC.
The power supply voltage must not exceed the recommended voltage, which otherwise may cause irreparable
damage to the device and the invalidation of the warranty.
Therefore:
•Do not replace power supply with a voltage greater than 110 V to 240 V AC
•Do not connect the device to the power if the power cord is damaged.
•Do not plug the device into mains supply until all cables have been connected correctly.
•Do not cut the cord.
Avoid placing the device next to central heating components and in areas of high humidity.
Do not cover the device with elements that obstruct the ventilation slots. If the encoder modulator has been kept in
cold conditions for a long time, keep it in a warm room minimum 2 hours before plugging into the mains. Mount the
device in vertical position with the connectors located on the top side. When replacement parts are required, be sure
the service technician has used replacement parts specified by the manufacturer or have the same characteristics as
the original part. Unauthorized substitutes may result in fire, electric shock or other hazards.
Safety check- Upon completion of any service or repairs to this device, ask the service technician to perform safety
checks to determine that the device is in proper condition.

Installations
RISK OF damage to the unit
Mechanically handling the unit may result in damage.
Do not connect the unit to the power supply before or during assembly.
Connect the unit as below instructed.
NO HOT PLUG!

CCTV and etc.
2. Optionally, connect the loop-through RF input coaxial cable.
3. Connect cable to RF output to STB/TV.
4. Power supply connection:
a) Connect the power plug to the unit mains connector;
b) Connect the power plug to the mains socket.
5. Connect the earth cable.

NMS Operation Guide
Network Management System (NMS) can remotely set config and monitor the device. It can be used only after being
authorized.
Except setting config by front panel, you can also use NMS_EN4.8.EXE on a PC to set and monitor device. Most of all
head-end equipments (satellite receiver, encoder, multiplexer, scrambler, modulator, and adapter, etc.) can be set by
NMS which is with UDP protocol and supports windows operation system.
2.1 NMS Login
NMS Login Interface
Default user name and password are “admin”. You can change the user name and password by “Setting”->”User
Setting” and then login again. If it’s the first time to use it, without any device info, the menu shows as below:

Current NMS is without any device, user can add per his device.
Below chapters will introduce above functions separately.
“Open Device” & “Save Device”: open saved config and save current config. If the config and the NMS are in the
same file, they can automatically run when opening or closing the network management software.
2.2 Add Frequency
“Add Frequency”: all devices can be divided and managed by frequency. Click “Add Freq Node”, then a dialog for
adding frequency shows up. Input a frequency, like 385MHZ”, and then click “OK” to confirm:
I: Menu Bar
IX: Restore Config
II: Open Device
X: Reload Config
III: Save Device
XI: Import Config
IV: Add Freq Node
XII: Export Config
V: Add Device
XIII: Device List
VI: Edit Device
XIV: Device Connection Info
VII: Del Device
XV: Device Config Operation
VIII: Save Config
XVI: Alarm List

2.3 Add Device
Add frequency under the frequency. Choose frequency and then click “Add Device”, then below dialog shows up:
Choose device type “4in1 SD MPEG-2 Encoder with DVB-T”, set device name (you can name as you like), and set IP
address and Port of the device. You can check IP address by clicking down key on the panel or you can enter into
“Network Setting” in the menu to check it. Default IP address and Port for 4in1 SD MPEG2 Encoder with DVB-T are
192.168.001.168 and 2009.
2.4 Edit Device
Click the device you need to edit and then you can edit any you like. If the device is not connected, then it shows as
below:
Then check by below steps:
Check if the connection info is correct:

1. If config is wrong, please choose the device and then click “Edit Device”, then below dialog shows up. Modify it and
then click “OK” to save.
2. Check if there is IP conflict. Turn off the device, and input “cmd.exe” at command column on your PC:
After entering into it:
Input “arp –d” to clear old “arp”information:
Input “PING”:
Here the ping is 192.168.1.168 (you can put your device IP address when you do it). Here we found 192.168.0.20
passed, which means there is already a device with 192.168.1.168. Then we can find the device out and modify the
IP address of the device or your device.

At the device list column, click device name to check it. Check the basic info (like firmware and software version) at
the device connection column and edit it at the right device operation area.
“Del Device”: delete the device you don’t need from the device list.
2.5 Check and Set Config
Note: user had better do the following operation before configuring the device:
Click button in NMS software, then click button to clear the old
parameter.

2.5.1 Output Setting
“Get”: Read current config from the device. “Set”: Confirm config and enable it.
2.5.2 Video/Audio Setting
“Get”: Read current config from the device. “Set”: Confirm config and enable it.

2.5.3 Edit NIT
2.5.4 Edit PSI

2.6 Public Function of NMS
Public function of NMS includes “Save Config”, “Restore Cong.”, “Reload Config”, “Import Config”, and “Export Config”.
Choose a device at device list.
“Save Config”: After committing or confirming set configuration, click this button to save all
configuration into “FLASH” (storage); you do this by front panel.
“Restore Cong.”:renew and start using the configuration. You can read the renewed configuration by clicking
“refresh” or “parse” on operation interface. Please click “Save Config” if it needs to be saved.
“Reload Config”:reload and use the configuration saved in FLASH. This function is usually used after “import config”,
and the new configuration is effective without restarting the device.
“Import Config”: import configuration of “export config” into FLASH; the imported config can be used after ‘reload
config’ or restart the device.
First please choose the config you want to import, and click “Erase”to clear current config and then import config
from FLASH. At this moment, the config cannot be used. You need restart the device or click “Reload Config”to start
new config.
“Export Config”: fetch the device’s configuration to local disk (computer). You can import this configuration when it
needs to renew the configuration or to use a back-up device in future.
