ITEM NO: HKM01 HDMI & USB, Audio, RS232, IR CAT5 Extender Over IP
The HKM01 HDMI, USB with Analog audio, RS232, and IR CAT5 extender design for extends and distribute
all signals over one CAT5 up to 150 meters, with local HDMI monitor output. It provides superior video
quality up to 1920 x 1200 resolutions, and using cost effective Cat5e cable, instead of HDMI, RS232 cables,
for an easy, neater and reliable installation. The local and remote units can be connected together for a
Point-to-Point connection via CAT5e/6 cable or a Point-to-Many connection via a managed network switch.
It is optimized for applications at broadcasting system, multimedia display and multi-data sharing, digital
signage, home network integration, and industrial control, hospital, education, security, Matrix network
system and system control over RS232 and equipment control over IR.

Work with Ethernet Switch Hub：
Ethernet switch type muse use Giga switch support IGMP and Jumbo Frame over 8Kb in order to
achieve the transmission.
Over Gigabit Ethernet switches: One to Multiple or Multiple to Multiple Connection:
1 Input to Multiple outputs connections via a Gigabit network switch
Multiple Inputs to Multiple outputs connections via a Gigabit network switch
Recommend installation using an independent Gigabit LAN; do not link with existing LAN to
avoid a lot of video data transmission slow down your network system.
When using multiple transmitters and receivers via a Gigabit network switch, identically
configure dip switches on the local and remote units to link them together.
In multiple connections keyboard and mouse are plug and play, for other USB devices just
simply press and click the USB keyboard Pause/Break”KEY on a receiver for three times to
get USB control; only one unit can have USB control over the source at any time.

3
For configurations that require greater distances, cascade the managed network switches to
extend the distance between the transmitter and receiver. Up to 16 transmitters can be
connected per individual network switch or between cascaded network switches.
Optional Model: SR01 Signal Repeater (order separately)
Extend data signal for an additional 120meters.
Application for HKM01 signals for extra long range transmission.
Ability to cascade connection with multiple SR01 for long range transmission
Built in LED status indication.
External power required.
Plug and play for easy installation.

Multiple to Multiple Mode Function:
HKM01 could do Multicast mode with back panel Rotary Switch function, to do multiple to multiple
transmission must consider bandwidth and data rate, it could be setup several groups as below :
HKM01 Switch can be set to a max. 16 channels, to work with a Gigabit Switch Hub, HKM01T and
HKM01R need to need to switch same channel in order to linking each other.
The video inputs highest rate around 150 ~200 Mbps, HKM01T could setup at max. 6 units as source
when using Gigabit Switch Hub.
Cable:
Link Cable use high quality Cat.5e UTP/STP/FTP or Cat.6 UTP cable
Ethernet Switch Hub：
Switch type must Giga switch with IGMP and Jumbo Frame over 8K Ethernet Switch Hub in order
to achieve the transmission.
HOT KEY Function：
HKM01 could use Ethernet Switch Hub to do one to multiple application, Under multiple HKM01R
for switching HKM01R external host USB flash drive port, make the external flash drive you want to
use with an external USB keyboard, to click three times “Pause/Break”KEY, the system will
redetect and connect USB devices.
Caution：
1. HKM01 do 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. When use HKM01T “Line In”function, the HDMI audio output of HKM01R Receiver will be
disabled.
3. When doing one to multiple applications, the HKM01R Receiver “MIC”won’t be affected.
4. IR receiving angle ±55degree, emitting angle 30degree，distance reach to 3-5 meters.
Web Setting Function：
HKM01 default setup at one to multiple mode (Multicast), the detailed setting could be changed
over web browser, you could input the IP address of transmitter / receiver at link column of browser
if you know the exact IP address of them.
To get the IP address of receiver:
Connect monitor with receiver, local IP shows on right bottom screen when receiver booting or
transmitter not connected( or no video input)
To get the IP address of transmitter:
Connect monitor with receiver, connect receiver with transmitter and set in the same
channel, remote IP shows on right bottom screen when receiver booting or no video input from
transmitter
System default IP setting is Auto IP, it will assign 169.254.X.X (subnet mask 255.255.0.0) to
transmitters and receivers, you could also set to DHCP or Static IP.
You computer must set in same subnet mask to enter the web setup page.
If you do not sure the IP address of transmitters/receivers you could reset the transmitters and
receiver to default by press the LINK button to power on (Press and hold until Green and Blue LED
Flash) to reset to default.

disabled, only analog audio output
For Receiver:
Video over IP:
This function setup the video signals send from network, default is checked.
Please note it will turn off HDMI output of receiver if this function be disabled, only analog
audio output
Copy EDID from this Video Output:
Check this box will auto copy EDID from the TV connected to receiver when receiver booting,
default is not checked.
In multiple connections transmitter will use default EDID 1080p with 2 channel audio, to
prevent EDID conflict recommend check this box in Unicast mode only.
