Cable & Transmission Distance:
Link Cable use high quality Cat.5e UTP/STP/FTP or Cat.6 UTP cable
Transmission distance will be affected by equipment (Switch HUB), cable quality…etc. When
using CAT.5e the max. Transmission distance up to 150M, using CAT.6 cable up to 180M.
You can also use model no: SR01 repeater for extended longer distance or using Gigabit Switch
hub which support IGMP protocol and Jumbo Frame 8K for signal distribution or extend distance.
System Default Settings:
Transmitter / receiver support Unicast and Multicast two mode, default is Multicast.
In Multicast mode it could be one to one, one to multi, multi to on or multi to multi applications.
The analog audio output of transmitter and input of receiver will be off in this mode, analog audio
only from transmitters send to receivers.
Analog audio bi-direction transmission only in Unicast mode, please refer to the web setting
chapter: Casting Mode
System default IP setting is Auto IP, it will assign 169.254.X.X (submask 255.255.0.0) to
transmitters and receivers, you could also set to DHCP or Static IP, please refer to web setting
chapter: IP Setup.

Bandwidth Chart:
The bandwidth will be varied based on different resolution. Higher resolution may not request
bigger bandwidth. Below Chart is the resolution and bandwidth status for reference.
Resolution (@60Hz)
Average Bandwidth (Mbps)
1080p
77 (24 ~ 91)
720p
46 (29 ~ 150)
480p
63 (36 ~ 73)
1600x1200 (UXGA)
59 (24 ~ 73)
1280x1024 (SXGA)
58 (31 ~ 76)
1024x768 (XGA)
118 (56 ~ 138)
800x600 (SVGA)
83 (64 ~ 107)
System scalability is limited only by uplink and stacking connector bandwidths but can
accommodate up to 16 Full HD video sources at once.
For example under Gigabit Ethernet network, the total flow must not exceed 1000Mbps to avoid
any delay on video streaming. If the video play with 1080p resolution, the transmitter allow
maximum up to 10pcs for simultaneous video streaming.
Above bandwidth chart not include USB transmission, it cost up to 50 Mbps when transferring mass
data.
USB Hot Key Function：
In multicast mode support multi USB keyboard and mouse in each receivers, just plug and play, but
only one USB FLASH drive / hard disk could be used at same time.
You have to click “Pause/Break” key three times of the keyboard on the receiver to establish USB
FLASH drive /hard disk connection.

Remote Control Function:
If you do not use PC computer management to setup receiver, then you could use
the IR infrared remote control to preset channel selection. Using the IR remote
control to the front of receiver will be ok.
Initial at first time use the remote control or after change battery of remote control,
the IR remote control and the equipment Remote ID must be using same ID. The
default Remote ID is 8.
To setting the Remote ID, Press and hold power button, then press button 8 to
complete the setting. + .(for example)

RS-232 Assign Mode：
System default setting of RS-232 is extender, the connection topology same as the channel
connection. RS232 ports of receivers only connect to the transmitter with same channel ID.
You could enable RS232 assign mode to fix the connection of RS232 without channel setting.
After the receivers and transmitter you want to keep RS232 connection established then press IR
remote button to enable RS-232 assign mode.
If IP address of transmitter has been changed you have to enable RS232 assign mode for recovers
again.
To disable RS232 assign mode press IR remote button
RS-232 Control command：
User could use RS-232 port of transmitters at baud rate 115200bps (8-N-1) to operate/setup the
receivers at same channel
Command format: >CMD_Address> Command Parameters
All accord receivers will run the command and parameters, we also add 3 kinds of user defined
numbers except MAC & IP (Device No、Group No、Party No) for flexible application:
Mxxxx The last 4 digits of MAC Address e.g.: 221868860123 = M0123
Ixxxx The last 2 column of IPAddress (HEX) e.g.: 169.254.012.034 = I0C22
Dxxxx Device No e.g.: Device No 1234 = D1234
Gxx Group No e.g.: Group No 12 = G12
Pxx Party No e.g.: Party No 34 = P34
CHx Channel No (HEX) e.g.: Channel 12 = CHC
ALL All receivers
Response format: <ACK_Address< Response character
Receivers will response message to transmitter as above format, if multiple receivers operate at
the same time they will not response to the transmitter by default.
To enforce response function please add “!”before commands and receivers will respond in
sequence by device number X 15ms.

Caution：
1. Not recommend to work with general LAN connection to avoid large video, data transmission or multicast
packets to slow down your other LAN devices.
2. Gigabit switch hub muse use support IGMP protocol and Jumbo Frame over 8K Ethernet Switch Hub in
order to achieve the best transmission quality
3. If monitor shows green screen or video not smooth, please check if the switch running under gigabit and
Jumbo Frame function enabled.
4. Using computer or mobile APP management the IP address should be set in same network segment.
5. Computer software operation, please refer to software operating instruction.

14
Web Setting Function：
Transmitter/receiver provide detail settings over web browser, you have to know the IP address
before setting.
There are three ways to get the IP address of receiver:
1.Local IP shows on right bottom screen when booting.
2.Press remote control button (IP Address)
3.Install Internet explorer plug-in: Bonjour , click device name to enter web setting page to get the
IP address(please refer software installations manual)
There are two ways to get the IP address of transmitter:
1.Connect a transmitter and receiver and set in the same channel, press remote control button
at receiver side (Host IP Address), it will shows the transmitter IP Address on
screen(must remove the HDMI cable of transmitter or turn off the video source).
2. Install Internet explorer plug-in: Bonjour , click device name to enter web setting page to get the
IP address(please refer Bonjour plug-in installation)
