Yes，

UD951B isn't an amp. It can't be used as an amp. Small Speakers can be use directly, And high-power Speakers needs to connect with an amp to drive.

In some cases, if you find that your speaker is a high-power speaker, but there is no sound when playing, this may be the lack of a power amplifier. You need to add another power amplifier.

For the "analog output is only 2CH" in the software interface, you can ignore it. Because the settings there have no affecting for the final playback effect.You don't need to worry about whether there is only 2CH analog output option on the driver interface.
 

The H951BT PC-USB input is based on CM108 chip, which has powerful functions, including 2CH analog output and S/PDIF digital output, even mixing effect, etc., All of these will be displayed on the interface.
 

But the H951BT only uses its S / PDIF Digital Output function, output to another more professional AC3 / DTS 5.1 decoding chip by S / PDIF Digital, decode it into 5.1 analog output. The CM108 The 2.0 analog function of the chip is not used in our products, even if the chip with 2.0 analog output. So we just need Select S / PDIF output, others we can ignore.

If you want to use the arc output function, You can connect the HDMI (ARC) port on your TV with the HDMI (ARC) out port of the UD951B, and then set your TV to play on the external speakers, or turn on the arc function. At this time, there will be no sound from your TV speakers, and the sound will be output from the arc. And your TV box connects directly to your TV via another HDMI cable. UD951B switches to arc input mode. The LCD will display "ARC".
 

You also can connect your TV box with the HDMI 1(or 2 3) of the H951BT, then connect the TV via the HDMI (ARC) out port of the h951bt, and connect the power amplifier and speakers via 5.1CH or COX/OPT. In this way, you can play video and sound at the same time.


Please refer to the following two modes for connection:

If you have this situation, please confirm the following items one by one:

1. All devices have been powered and started normally.

2. The connection of all devices is correct and there is no wrong connection.

3. The decoder switches to the corresponding signal channel. If you are connecting HDMI 1 or 2 or 3, the decoder signal channel should be switched to the corresponding HDMI 1 or 2 or 3, and it is same for other signal channels. The current signal channel will be displayed on the LCD screen of the UD951B decoder.

4. The volume of all devices is adjusted to the normal range (not in the mute state and the mute key is not pressed ).

5. The audio input / output settings of all devices are correct.

Because devices each customer used and usage mode maybe is different, we can't give you a standard solution. If you have any problems, you can get more information by reading the user's manual of your device, or contact us, and we will try our best to help and solve your problems.
 

NOTE:

*This isn't an amp. It can't be used as an amp. Small Speakers can be use directly, And high-power Speakers needs to connect with an amp to drive.

*The computer need be installed the driver of the system before using the H951BT unit. At present, only windows system is supported.

The driver can be got in the USB flash disk attached with the product or online from our website (please click "download" to find the corresponding " H951BT " driver to download.

Yes.

When you connect to the UD951B decoder and the sound of the TV or TV box is set to source code output (raw data / passthrough / bitstream), By now the audio signal will be decoded and output by the H951BT decoder, instead of audio decoding by TV or TV box. Therefore, the original TV ( or remote control ) / TV box ( or remote control ) is going to can no longer control the volume.

All is almost the case when you use an external / stand-alone decoder, Which you can no longer control the volume through the original TV ( or remote control ) / TV box ( or remote control ).

If you really want to control the volume by the original TV ( or remote control ) / TV box ( or remote control ), you can set the TV (or TV box) sound to the" PCM " output, so that the volume can still be controlled by the original TV ( or remote control ) / TV box ( or remote control ).

But the " PCM " output is only virtual 5.1.

How to use the print server with two different Lan networks ? 


After do some network settings on the server, and the print server can be used with two different networks at the same time.

In theory, it can be used with a maximum of three different network segments at the same time.

The Wifi connect to one LAN network, the LAN1 port connect to one LAN network, the LAN2 port connect to one LAN network.

But in most cases, customers only need to connect 2 LAN networks at most. We usual will recommen our customers to connect by WiFi and LAN 2 port first



If you need to use the server on 2 Lan different networks at the same time,

The setting method is as follows: 


1.  In Lan 1(one of the two different LAN networks you want to connect), complete the connection settings (wireless and wired) between the print server and your Lan 1. And make sure that the computers in your Lan 1 can share the print server normally.


2.  Get the network segment information of your LAN 2.

You can view the network information of your LAN 2 on anyone of the computers in the LAN 2, to get the IP network segment of your LAN 2 and record it.

Such as IP:   192.168.30.161

3.  Set up the IP of the server LAN 2 port according to the IP segment information of LAN 2 you got.

①  On a computer in your LAN 1, enter the IP address of the print server in a browser (It is the IP address the server in your LAN 1). Then log in and enter the background of the print server.

Find  "LAN2 interface"  -  "Protocol"  and select  "Static"





② Add an IP address of the same network segment as LAN 2 in IPv4.

For example, the IP of your Lan 2 network is:   192.168.30.161

You can set up the IP address of Lan 2 port to:  192.168.30.188   
Or  192.168.30.XXX      and so on.

This IP address can't be conflicting or same with IP addresses of other devices in your LAN 2.

The same is true for other types of IP addresses.

Then click     "Submit"


4. Connect the LAN 2 port of the server to the network port of the router or switch of your LAN 2 network by a network cable. Then you can use the IP address you set up for the Lan 2 network to add a printer or a USB device to any computer in your Lan 2 network.

In this way, your Lan 1 is connected to the server through WIFI, and your Lan 2 network is connected to the server through Lan 2 port of the server.

As shown in the figure below:

 


Of course, you can also use this method to  set up your Lan 2 wired to LAN 1 port of the server and your Lan 1 wired to LAN 2 port of the server.

The premise is that the connection setting between the server and one of your networks has been completed, and then enter the server background through the server's IP address, and modify the IP of LAN 1 port or LAN 2 port to the IP of the same network segment as the second LAN you need to connect to.


 

MFP (multi-function) series print / share server has two different functions, one is to share printer, the port is IPP or RAW, through TCP / IP protocol communication; The One is a shared USB device, which uses USB port and communicates through USB protocol.

If you are using our MFP (multi-function) series print / share server, if the printer you added before and used normally suddenly fails to work, it may be that when you print files, the USB port of the server is occupied by a user and share the USB device at the same time, or after sharing the USB device, The USB connection tool did not disconnect from the USB device，resulting in your inability to print.

The USB port of MFP (multi-function) series print / share server cannot use TCP / IP printer and share USB device at the same time. Otherwise, when the USB device is shared, the USB port will be occupied and the printer cannot be used.

If you encounter this situation, please let all users to disconnect from the USB device on the server and stop sharing the USB device. And you can also try to power off the server and restart the server again. After the USB port is no longer occupied, you can use the printer normally.

Of course, you can also directly connect and use the printer through the "shared USB device", but this method requires running the "USB connection tool" to connect to the USB device on the server. If the shared printer is added through IP address, you can directly send the print command to the printer without running the "USB connection tool" to connect to the USB device on the server.

You can choose the suitable working mode according to your actual situation.

Thank you!

When setting up the connection between the print server and your LAN, please first set up the "wireless connection" of the print server, and then set up the "wired connection" with your LAN (wired connection to your router or switch). In this way, even when the print server is disconnected from the "wired connection" of your LAN, the "wireless connection can still communicate with your work network (LAN) and can be used normally.

Otherwise, if you first wired the server to your LAN (connect your router or switch), and set up "wired connection", and then set up "wireless connection". When the server is disconnected from the "wired connection" of your LAN, the "wireless connection" between the server and your working network will be unable to communicate and unavailable.

So please first set up the "wireless connection" between the server and your LAN (if you don't need wireless connection, you can directly set up wired connection), and then set up the "wired connection" between the server and your LAN.

When setting "unable to connect", please make sure that the lan1 or lan2 port of the server is not connected to any device“ After wireless connection is set, lan1 and lan2 ports can be connected to any device without affecting the use of wireless connection.

If you accidentally make the wrong setting, please insert into the "RST" hole by the needle (or similar object) , long press for 5 ~ 10 seconds, and release when the "sys" light flashes, the server will return to the factory settings. You can make the correct settings again on the server.

Thank you.

This is usually caused by setting the "wired connection" first and not the "wireless connection" first.

If you are not that set up "wireless connection" first and then set up the "wired connection" ，but are that connect the server to the router (or switch) first, and then get the wired connection IP address through "Quick installation tools", then you may get a wired connection IP address, such as IP: 192.168.1.4 (or similar). However, after obtaining the IP, the server system will automatically change the IP to 192.168.1.188 (or similar). At this time, the previous 192.168.1.4 will be invalid, and only the IP 192.168.1.188 automatically corrected by the later system will be available.

Therefore, in order to avoid trouble, please set the "wireless connection" of the server first, and then set the "wired connection"

If you accidentally make the wrong setting, please insert into the "RST" hole by the needle (or similar object) , long press for 5 ~ 10 seconds, and release when the "sys" light flashes, the server will return to the factory settings. You can make the correct settings again on the server.

Thank you.
