2.2 Installation precautions

This section to explain the cautions the users must have to avoid any injures when using or installing the product. For this reason, please read all details here before installing or using the product.

General Precautions

Must be operated and maintained free of dust or dirty. The cover should be securely fastened, do not open the cover of the products

with the power on.

After use, securely stow away all loose cables, external antenna, and others.

Power precautions

When you connect the power source, make sure it will not cause any overload. Avoid operating on a wet  oor in the open. Make sure the extension cable is

in good condition.

Make sure the power switch is o before you start to install the device.

Grounding Requirement

All function modules’ good grounding is the basis of reliability and stability of devices. Also, they are the most important guarantee of lightning arresting and interference rejection. Therefore, the system must follow this rule.

Grounding conductor must be a copper conductor in order to reduce high

frequency impedance, and the grounding wire must be as thick and short as possible.

Users should make sure the both ends of grounding wire are electric

conductor and antirust. It is prohibited to use any other device as part of grounding electric circuit. The area of the conduction between grounding wire and device’s frame

should be no less than 2,5mm2.

Follow the help guideline for set IP out con guration.

IP Output: The IP Output option, must be enable. Service IP: The IP Output Port address. The format is xxx.xxx.xxx.xxx (like as

192.168.2.137).

Output IP: The IP Output data receive address. The format is xxx.xxx.xxx.xxx

(like as 224.2.2.2). After set the Output IP address , you must use the new address to receive IP Output data.

Subnet Mask: General is 255.255.255.0, it is must the same in a local area

network. Gateway: If the device is in di erent net segment, you must set the gateway. Port: The UDP protocol port (like as 8001), you should use Output IP and new

port to receive IP Output data (like as udp://224.2.2.2:8001).

Note: The signal available at the IP Output is the same as the RF output. The protocol used for the MUX stream is UDP, so to see the modulated

channels you need a program that has this protocol, like VLC Media Player.

In recent versions of this particular program is necessary to put @ before the

IP address, for example, “udp :/ / @ 224.2.2.2:1234”.

7.3.2 NIT, Hierarchy and LCN Con guration

In this menu is possible to edit the Transport Stream ID, Original Network ID (each unit has to have a di erent TSID and ONID), assign a Network name (the same in all units of the same network) and more. After each change is necessary to press Update NIT.

By pressing “Add” you will have access to the menu of the next images:

In this menu is possible to edit the LCN of each program (in order to be listed correctly the Hierarchy Information must be set to “a-1, a-2 or a-4”, the same on each unit of the same network). The LCN can be set by any order, in the image above it can be observed that the unit 2 will have program 1, 3 and 4 and unit 1 will have program 2.
