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.

You could use the IR infrared remote control to preset channel selection and other menu function.
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.

Menu 22 When disable USB extender function it will also disable keyboard mouse
function.
Menu 25 Display or hide TV wall setting in the webpage.
Menu 27 You could disable keyboard mouse extender if any compatible issue, it will use
USB extender instead of keyboard mouse extender.
Menu 33 To set customize IR remote, need to be import to RX by RS232 or Telnet
command
Menu 35 For monitors which detect HDMI 5V to enter sleeping mode.
Menu 36 Turn off monitor by CEC command via RX.
Menu 41 Pass-Through means output resolution follow TX EDID, Auto Detect(Per EDID)
means output resolution follow monitor EDID of RX, Customize resolution need to be
setup by RS232 command or web page
Menu 47 Use default EDID at TX side, or copy monitor EDID at RX side. (In multicast mode)
Menu 49 Monitor HDCP version setting, with incorrect HDCP version setting it will show

RS232 Control
In RS232 extender mode, user could use RS232 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.: 2218688612AB = M8612AB
Ixxxx The last 2 column of IP Address (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
TX Transmitter which connected to RS232 port currently.
RX Receiver which connected to RS232 port currently.(for Auxiliary mode)
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.
Example:
>CMD_M8612AB> CHANNEL 12
(Set receiver which last 6 digits MAC Address is 8612AB to Channel 12)
<ACK_M8612AB< OK
(Receiver which last 6 digits MAC Address is 8612AB response “OK”)
