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/CAT.6 cable connect transmitter and receiver directly without Ethernet switch, the
maximum transmission distance up to 150M.
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.
Unicast mode suitable for one to one or multiple transmitters to one receiver applications.
Analog audio bi-direction transmission only in Unicast 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.
We recommend DHCP or Static IP mode in mass deployment to prevent IP conflict problem.
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) Resolution (@60Hz) Average Bandwidth (Mbps)
3840x2160 (2160p) 218 (146~268) 1280x1024 (SXGA) 113 (79~150)
1920x1080 (1080p) 133 (80~210) 1024x768 (XGA) 81 (72~120)
1280x720 (720p) 147 (112~177) 800x600 (SVGA) 66 (49~82)
1600x1200 (UXGA) 81 (57~105) 640x480 (VGA) 43 (29~56)
Above bandwidth chart not include USB transmission, it cost up to 50 Mbps when transferring mass
data.
System scalability is limited only by uplink and stacking connector bandwidths, 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 7 pcs for
simultaneous video streaming.
For 8~16 sources: use switches which support 802.3ad Link Aggregation or smart (or intelligent)
switches to get 2 Gbps or more bandwidth.
For over 16 sources: use switches which support SFP+ uplink or stackable switches to get 10 Gbps
bandwidth.
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 or IR remote MENU
function 14 to establish USB FLASH drive /hard disk connection.

Remote Control Function:
You could use the IR infrared remote control to preset channel selection. Using the IR
remote control aim to the front panel of receiver or external IR receiver cable 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 for transmitter is 7, for receiver is 8.
To setting the Remote ID, Press and hold power button, then press button 8 to complete
the setting. + .(for example)
