The WiMi6200T is a high quality 1080P60 video and audio encoder. WiMi6200T

compresses video using H264 standards, and streams this compressed signal over an IP

network via Ethernet. Using the WiMi6200R decoder unit will allow the IP network stream

to be decoded and converted back to video plus audio. Alternatively a software decoder

such as VLC player may be used to decode the IP network stream generated by the

WiMi6200T or WiMi6200R.

Quick Start 1 - Power up and streaming video

1) Remove the WiMi6200T and WiMi6200R from its packaging. The WiMi6200T or

WiMi6200R comes with a 12 volt power converter (120/220/240V AC to 12 VDC).

The WiMi6200TW needs the V-mount or Gold mount battery that will supply the

power to the system.

2) Wireless operation:

A. Set the DIP switch of ENC Rate to position and DIP switch of Wi-Fi Ch.

to position on the front panel of WiMi6200TW. And set the DIP switch

of Wi-Fi Ch. to position on the front panel of WiMi6200RW.

B. Connect suitable video source to the HD-SDI input port on the WiMi6200T, and

connect the HD-SDI output port on the WiMi6200R to the appropriate HD-SDI

display device via 75 ohm SDI cables. Video resolution can be from PAL/NTSC

up to 1920 x1080 at 59.94 Hz or frames/second, HD-SDI or 3G-SDI.

C. Attach the V-mount/Gold mount battery to the WiMi6200TW, and connect the

12V DC plug into the 12V jack of the WiMi6200RW. Turn on WiMi6200TW,

WiMi6200RW, video source, and display.

3) LAN operation:

A. Prepare a Cat.5e LAN cable (not supplied), two HD-SDI cables (not supplied)

and suitable HD-SDI source (Video Camera or etc.)/HD-SDI display.

B. Connect one end of the LAN cable to the LAN port of the WiMi6200T and the

other end to the LAN port of the WiMi6200R. And connect suitable video

source to the HD-SDI input port on the WiMi6200T, and connect the HD-SDI

output port on the WiMi6200R to the appropriate HD-SDI display device via 75


24

ohm SDI cables. Video resolution can be from PAL/NTSC up to 1920 x1080 at

59.94 Hz or frames/second, HD-SDI or 3G-SDI.

C. Connect the 12V DC plug into the 12V jack of the WiMi6200T and WiMi6200R,

each. Turn on WiMi6200T, WiMi6200R, video source, and display.

4) 3x LEDs will blink for 5~6 seconds, and then one yellow LED (LINK) will blink for

35~37 seconds until the unit boots into its standby/ready condition.

5) After booting of the WiMi6200T, the green LED (HD-SDI) will blink until it detects the

video signal, and the yellow LED (LINK) will stop blinking after connection of the LAN

(Wi-Fi) link is established. The yellow LED on the RJ45 port of LAN will blink when

the transmitter starts to send A/V data in LAN mode.

6) After booting of the WiMi6200R, the green LED (HDMI) will blink until it outputs the

video signal to the display device, and the yellow LED (LINK) will stop blinking and

keep lighting after the connection from the WiMi6200T.

7) You can see the video on the display.

A full list of supported video formats was described in section 1.8 of this manual.

WiMi6200T + WiMi6200R are shipped with the following defaults:

- Enc. Rate on WiMi6200T is 12Mbps.

- SYS-ID on WiMi6200R is SLAVE1

- Wi-Fi Ch. and SSID of the 6200TW and 6200RW: Ch.157 with SSID of WiMi6200_03

- Factory default IP addresses are 192.168.0.161 (WiMi6200T) and 192.168.0.162

(WiMi6200R).

- Connection via LAN will allow video from the WiMi6200T to be streamed to the

WiMi6200R without any changes being made to the settings. Customers with both

units should test this configuration first. And then, you can change the video port on

the WiMi6200T and WiMi6200R via Select button or a web browser explained below

Quick Start 2.

- Customers with WiMi6200T encoder only should test with PC with some change

Quick Start 2 - Connecting a web browser to adjust/ change settings.


25

The WiMi6200T/R has a web interface for configuration of all audio/video parameters,

network functions etc. Currently you have to use Internet Explorer or Chrome web browser

for this function.

Having connected the WiMi6200T to a video/audio source and 12V DC, next connect the

Ethernet port of WiMi6200T to an Ethernet L2 switch (L2 Hub), or to a PC directly using an

Cat.5e UTP cable (not supplied).

Connect a laptop or PC to the same network that the WiMi6200T is connected to. And,

change the IP address of PC to 192.168.0.xxx. Open a web browser and type the

192.168.0.161 on the URL field of the web browser. Then you can see the WiMi6200T web

page. All the same procedure will be applied to the WiMi6200R, except the IP address,

192.168.0.162.

Quick Start 3 - Video/audio streaming server for RTSP client (VLC player)

The WiMi6200T can be set to operate as a streaming server that sends video/audio to a

software decoder, such as the VLC player on the PC, Ace Player for IOS devices and BS

Player for Android devices.

To test software decoding using VLC player please follow these instructions:

1) Browse to the WiMi6200T IP address using web browser, such as the Internet

6 InterComm Audio R/W Turn On or Off the InterComm audio


60

7 RTSP Relay Server R/W

Turn on or off RTSP Relay Server for the RTSP relay streaming

server mode. In the RTSP Relay Server mode, the received audio

and video data from WiMi6200T will be transparently streamed

out to the RTSP clients that were connected to the WiMi6200R

through the Ethernet or IP. Since RTSP Relay Server of

WiMi6200R is just streaming data from WiMi6200T out, data

format and bit-rate of audio and frame-rate and bit-rate of

video are same with WiMi6200T. Although the relay streaming

server is turned on, the normal decoding on the WiMi6200R

over Ethernet will be performed, simultaneously.

8 RTSP Streaming

Mode R/W

P2P: Point to point mode. In this mode, a stream will be

added/removed whenever a RTSP client connected and

disconnected. The number of RTSP clients can be limited by the

encoding rate of the WiMi4000T/6200T/6400T due to the

limitation of WiMi6200R CPU performance.

Multicast: Point to multi-point mode.. In this mode, there will

be always a stream that all RTSP clients can receive it.

9 RTSP Group IP R/W

Multicast IP address. Default multicast IP address is 227.2.2.7.

This Group IP address must be a unique address, if there are

two or more RTSP Servers of WiMi6200R or multicast mode

WiMi6200Ts on the same network.

There is no need to input this multicast IP address on the RTSP

client program when the RTSP server is running at multicast

environment, because the RTSP client program can fetch this

multicast address from the server automatically. So, the IP

address of the WiMi6200R and the port number should be

input to the URL field of the RTSP client program like below.

rtsp://192.168.0.162:8554/stream

10 RTSP Multicast

TTL R/W

Time to live value of IP when the RTSP relay streaming server is

running on multicast mode⑧.

③ Configure the other WiMi4000R/6200R/6400R with the same process described above ②.

④ Configure the L2 Ethernet switch can support IGMP snooping function.


65

IGMP Snooping Function of the L2 Ethernet switch

A switch will, by default, flood multicast traffic to all the ports in a broadcast domain (or the VLAN equivalent). Multicast can cause unnecessary load on host devices by requiring them to process packets they have not solicited. When purposefully exploited this is known as one variation of a denial-of-service attack. IGMP snooping is designed to prevent hosts on a local network from receiving traffic for a multicast group they have not explicitly joined. It provides switches with a mechanism to prune multicast traffic from links that do not contain a multicast listener (an IGMP client).

IGMP snooping allows a switch to only forward multicast traffic to the links that have solicited them. Essentially, IGMP snooping is a layer 2 optimization for the layer 3 IGMP. IGMP snooping takes place internally on switches and is not a protocol feature. Snooping is therefore especially useful for bandwidth-intensive IP multicast applications such as IPTV.

IGMP querier

In order for IGMP, and thus IGMP snooping, to function, a multicast router must exist on the network and generate IGMP queries. The tables created for snooping (holding the member ports for each a multicast group) are associated with the querier. Without a querier the tables are not created and snooping will not work. Furthermore IGMP general queries must be unconditionally forwarded by all switches involved in IGMP snooping. Some IGMP snooping implementations include full querier capability. Others are able to proxy and retransmit queries from the multicast router.

Prerequisites for multicasting A/V over IP network

There must be one or more Multicast routers on the network to transport multicast A/V traffic on the network that the single WiMi4000T/6200T/6400T and multiple WiMi4000R/6200R/6400R are working. And all the L2 Ethernet switches on the network between the WiMi4000T/6200T/6400T and WiMi4000R/6200R/6400R must support IGMP snooping function. If there is a L2 Ethernet switch that does not support IGMP snooping function, then the multicast A/V traffic will be flooded to every ports that can be resulted in blocking the multicast A/V traffic.

Multicasting A/V over single sub-network

There is one simple solution for replacing an expensive multicast router, if the multicasting is transmitted and received in one sub-network. Some of advanced L2 Ethernet switch transmits IGMP query packets through their Ethernet port. If there is no need to multicast IP traffic over the different sub-network, then you can use this cheap L2 Ethernet switch. The one sample of this advanced L2 switch that Nimbus has tested is the HP’s V1910-16G Switch (JE005A).

3.6 Operation of USB port

The USB port operation is applied to both WiMi6200T and WiMi6200R

IP configuration of the WiMi6200T and WiMi6200R through the USB port

Create both a config.tx and a config.rx files on the root directory of the USB memory stick.

The config.tx file must include below text

FACTORY_DEFAULT=YES : This line must be located at first line of the file.

ipaddr=192.168.0.161 : IP address of the WiMi6200T

netmask=255.255.255.0 : Sub-net Mask of the WiMi6200T

gatewayip=192.168.0.1 : Gateway IP address of the WiMi6200T

PEER_IP=192.168.0.162 : IP address of the peer device (WiMi6200R)

# Comments of the above configurations

The config.rx file must include below text

FACTORY_DEFAULT=YES : This line must be located at first line of the file

ipaddr=192.168.0.162 : IP address of the WiMi6200R

netmask=255.255.255.0 : Sub-net Mask of the WiMi6200R

gatewayip=192.168.0.1 : Gateway IP address of the WiMi6200R

PEER_IP=192.168.0.161 : IP address of the peer device (WiMi6200T)

Insert the USB memory into the USB port of the WiMi6200T, and recycle the power.

Wait for 3~4 seconds until the LED stops the fast blinking, and after stop fast blinking the USB memory must be removed from the WiMi6200T/R.

Note: The USB memory must be removed from the WiMi6200T/R once the fast blinking of LEDs stops.

Note: The character “#” in the beginning of the line will ignore the rest of text on the same line.

Note: If there is only “FACTORY_DEFAULT=YES” in the file, then it will work as the factory reset operation.
