FAQs

The SGSW-2840P, SGSW-2840P4 and SGSD-1022P series Managed PoE switches support PoE management and monitor only via Web management interface, which is the easiest and efficient way for the PoE power control.

1. Different Flash component used.
2. Different firmware structure and management functions.
3. Due to the differences, the firmware is incompatible between version 1 and version 2.

1.Remote full management solution.
2.Increase more IEEE 802.1Q VLAN group (from 26 to 256).
3.SSL / MAC address limit / filtering, source IP-MAC / port-binding function
　enhances.
4.Remote Telnet management function enhances.
5.Support SNMPv3 and 4 RMON groups.
6.Configuration backup / restore function enhances.
7.Add Web firmware upgrade method.

No, it does not support SSH, Telnet or TFTP access.

We recommend you to use Media Player12 or above version, Different DLNA players have limitation for media format support, please check the media player manual for the list of supported format.

There are three ways to convert the video source, one is to use DIP switch, while the other is to set VLAN port and go with HDMI Splitter(Matrix).

1. A Tx (transmitter) supports DIP switch for 16 channels, and every time when you convert the source you have to switch DIP of all units to the same number, and then reboot all the units.

2. You could set VLAN to convert the video source, please refer to the topology below and imagine that the concept is based on your issue.

You can set up port-based VLAN for that Transmitter (IHD-200T), and then for the receiver (IHD-200R), You can just dynamically swap the receiver port to a different VLAN for video source change. You can swap VLAN via Web interface of the switch, say, WGSW-24040.

However, to be more faster and easier to swap the sources, you can consider using TELNET or RS232 Console via CLI (command line).

Since the commands are just fixed commands, you can record those commands into a macro, and just double click on specified macro, and then the commands will be sent to the switch in a very short time and swap your video source. By the way, in this setting, all the transmitter(s) and receiver should set as the same group.

Instructions about the topology above:

As for Test A, we set port1 and port3 to a VLAN, and set port2 and port4 to another VLAN. The Rx will convert the source if we change the connection of Rx and switch from port3 to port4.

As for Test B, , we set port1 and port3 to a VLAN, and the Rx will convert the source if we issue the command via telnet to set port2 and port3 to a VLAN.

3. You also could use HDMI Splitter(Matrix) to do the sources convert.

As you see, two sources connect to the input of HDMI Matrix, and output to Tx, then Tx and Rx all connect to the switch.
In this case, we use the HDMI Matrix controller to select the source, which one should be transmitted.
