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.
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)

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)

RS-232 Control:
User could use RS-232 port of transmitters to operate/setup the receivers at same channel by program
like Hyper Terminal which built-in Windows XP and before version.
Hyper Terminal setting:〔115200 bps (8-N-1),Flow control: None〕(Properties -> Settings -> ASCII
Setup…and select “Send line ends with line feeds”&”Echo typed characters locally”)
★We recommend set the RS232 routing for all receivers to one transmitter to avoid RS232 connection
broken by video channel switching.
Command format: >CMD_Address> Command Parameters
Address, command and parameters are char, not hex code
Enter (LF or CR+LF) is required to execute the command
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:
Mxxxxxx The last 6 digits of MAC Address of receiver e.g.: 2218680123AB = M0123AB
Ixxxx The last 2 column of IPAddress (HEX) of receiver e.g.: 169.254.012.034 = I0C22
Dxxx Device No e.g.: Device No 123 = D123
Gxx Group No e.g.: Group No 12 = G12
Pxx Party No e.g.: Party No 34 = P34
Cxxx Channel No e.g.: Channel 123 = C123
ALL All receivers
Response format: <ACK_Address< Response character
Receivers will response message to transmitter as above format and send Newline after
When send command to multiple receivers(address as Gxx, Pxx, Cxxx, and ALL) they will not response.
