HKM02B-4K
Introduction
HKM02B-4K uses AV over IP technology to route up to 1,000 4K HDMI sources to up to 60,000 displays over
IGMP and Jumbo frame protocol gigabit switches, which can achieve HDMI signal extending, distributing,
switching and routing.
Additionally, the boundless switching function allows you to use one mouse to operate multiple PCs by
moving the mouse cursor across the monitors' borders.
HKM02B-4K is a multifunctional system that integrates multiple media. You can perfectly apply it to
large-scale security rooms, classrooms, trading rooms, and many more.
Features
Resolution up to 4K@30Hz 4:4:4
Signal extension up to 150M over CAT5e (or greater), 60KM over fiber optic cable.
workable with Ethernet switches for HDMI extension, distribution, switching, and matrix.
Built-in loop out, an extra local HDMI display at TX side.
Built-in 4 USB ports for keyboard, mouse, flash drive...etc.
Supports up to 8 x 16 video wall.
Supports video scaler, 4K to 1080p/ 1080p to 4K.
Supports HDMI audio embedding and extraction function.
Supports USB, full-duplex RS232, bi-directional IR, analog audio transmission.
Supports RS232 signal distribution.
workable with SR01X (IP repeater) for longer distance.
Managed via Windows based software, Android/iOS APP, Web GUI, IR remote, panel pushbutton,
Telnet API, RS232 console.

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: SR01X 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 Casting Mode/IP Settings
Casting Mode
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.
IP Mode
System default IP setting is Static IP, IP mapping to last 4 digits of MAC address (Hex), for example MAC
XX:XX:XX:XX:12
‧‧
:AB
。。
, the IP address will be169.254.18
‧‧
.171
。。。
You could also set to DHCP or Auto IP, please refer to web setting chapter: IP Setting: Page 18.
In Auto IP mode it will assign 169.254.X.X (subnet mask 255.255.0.0) to transmitters and receivers without
DHCP server.
We recommend Static IP mode when using APP or PC software control to prevent any IP change
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.
