Installation Procedure

Environment Requirement

Project	Requirement
Room Space	When installing multi-row of racks, please make the distance 1.2~1.5M between front door and back door, and the distance 0.8M between rack and wall.
Room Floor	Non-conducting, dust-free Ground anti-static material volume resistivity: 1×107-1×1010W, ground current-limiting resistance: 1MW, floor bearing weight: ＞450Kg/m2
Temperature	Long-term operation: 5~40ºC, short-term operation: 0~45ºC, air-conditioner is a good option.
Relative Humidity	Long-term operation: 20%~80%, short-term operation: 10%-90%
Ambient Pressure	86-105KPa
Doors and Windows	Seal by dust-prevention rubber strip, double glass is a good option for window and seal it tightly.
Fire Requirement	Automatic fire alarm system and hand-held fixed fire extinguish system are required.
Power Requirement	3 stand alone power supply system for equipment, air-conditioner, and lighting. Alternating current power supply for equipment (220V, 50Hz, 24.2W). Please check before running the device.

Grounding Requirement

Good ground wire design is the base of the whole system, and is essential to lightning protection and anti-interference. The system must follow above principles.
Keep good electrical contact between both ends of outer conductor and shielding layer and the appearance of metal case of the connected device.
Make sure that connections of both ends of the ground wire are with good electrical contact and prepare for corrosion prevention treatment.
Do not use other device for ground wire electrical connection.
The sectional area of ground wire from rack connecting to anti-thunder unit must be greater than or equal to 25mm2

Rack Grounding

Ground terminals of racks in one room should be separately connected to protective are copper bar provided by side board. And ground wire should be as far as possible short. If the wire is too long when installing, please cut off to avoid ground wire coiling. The sectional area of guide line of ground terminal row must be greater than or equal to 25mm2.

Equipment Grounding

When grounding, use guide line to connect protective area binding post to the protective ground wire row of assembly rack.

Power Cable Connection

Power jack is on the left of rear panel, power switch is at the left side of power jack, and ground connecting screw is at the lower left side of power jack.
Connecting power cable: put one end of the cable into the AC power jack and the other (power plug) to the AC power supply.
Connecting ground wire: when connecting alone to protective area in the room, you can use independent ground or common ground with other equipments (like transmission equipment) with a resistance less than 1.

Note :

Before connecting power cable, please turn power switch to “O” position and it’s required to ground with power supply system.

Signal Line Connection
Before operating, user should connect all devices requiring cables.

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 SC-4116_DVB-T2_Modulator_3

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.

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.

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

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.

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:

SC-4116_DVB-T2_Modulator_6

SC-4116_DVB-T2_Modulator_7

Add Device
Add device under the frequency. Choose frequency and then click “Add Device”, then below dialog shows up:

ADD “DVB-T Modulator”

Choose device type “DVB-T/T2 Modulator(ASI)”, 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 DVB-T2 Modulator are 192.168.000.240 and 2009.

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:

1. Check if the connection info is correct:

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:

SC-4116_DVB-T2_Modulator_11

After entering into it:

SC-4116_DVB-T2_Modulator_12

Input “arp –d” to clear old “arp” information:

SC-4116_DVB-T2_Modulator_13

Input “PING”:

SC-4116_DVB-T2_Modulator_14

Here the ping is 192.168.0.20 (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 192.168.0.20. Then we can find the device out and modify the IP address of the device or your device.

After shooting the problem, the icon turns SC-4116_DVB-T2_Modulator_15

SC-4116_DVB-T2_Modulator_16

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.

Check and Set Config

Note: user had better do the following operation before configuring the device:

Click SC-4116_DVB-T2_Modulator_17 button in NMS software, then click SC-4116_DVB-T2_Modulator_18 button to clear the old parameter.

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.
