1.1 Product Overview
B-QAM-SDI-IP-2CH-LL series products are QuestTel‟s new breakthrough all-in- one devices which integrate encoding (MPEG-2 HD/SD, MPEG-4/AVC H.264 HD/ SD) and modulating to convert V/A signals into DVB-C RF output. It has equipped with
2 SDI channels input and 1 ASI input and output with 2 ASI ports and 1 UDP IP port. Now, the latency problem has been greatly reduced to achieve an extremely low value from the encoding progress to the decoding terminals. It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/SDI /) as needed. The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signals are to be received by DVB-C TVs or STBs and etc.

2.5 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 adopt 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 2 ends of grounding wire well electric conducted and be
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 25 mm2.

Chapter 4 WEB NMS Operation
User not only can use front buttons to set configuration, but also can control and set the configuration in computer by connecting the device to web NMS Port. User
should ensure that the computer‟s IP address is different from the B-QAM-SDI­IP-2CH-LL‟s IP address; otherwise, it would cause IP conflict.
4.1 login
The default IP address of this device is 192.168.0.136. (We can modify the IP through the front panel.) Connect the PC (Personal Computer) and the device with net cable, and use ping command to confirm they are on the same network segment. I.G. the PC IP address is 192.168.99.252, we then change the device IP to
192.168.99.xxx (xxx can be 0 to 255 except 252 to avoid IP conflict). Use web browser to connect the device with PC by inputting the Encoder & Modulators IP address in the browser‟s address bar and press Enter. It will display the Login interface as Figure-1. Input the Username and Password (Both the default Username and Password are admin.) and then click LOGIN to start the device setting.

Safety Instructions
Read before operating equipment.
1. Cleaning - Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
2. Power Sources - Use supplied or equivalent UL/CSA approved low voltage DC plug-in transformer.
3. Outdoor Antenna Grounding - If you connect an outside antenna or cable system to the product, be sure the antenna or cable
system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.
4. Lightning - Avoid installation or reconfiguration of wiring during lightning activity.
5. Power Lines - Do not locate an outside antenna system near overhead power lines or other electric light or power circuits or where
it can fall into such power lines or circuits. When installing an outside antenna system, refrain from touching such power lines or c
ircuits, as contact with them might be fatal.
6. Overloading - Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.
7. Object and Liquid Entry - Never push objects of any kind into this product through openings as they may touch dangerous voltage
points or short out parts, resulting in a fire or electric shock. Never spill liquid of any kind on the product.
8. Servicing - Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
9. Damage Requiring Service - Unplug this product from the wall outlet and refer servicing to qualified service personnel under the following conditions:
When the power supply cord or plug is damaged. If liquid spills or objects fall into the product. If the product is exposed to rain or water. If the product does not operate normally by following the operating instructions. Adjust only those controls that are
covered by the operating instructions. An improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation.
If the video product is dropped or the cabinet is damaged. When the video product exhibits a distinct change in performance, this indicates a need for service.
