1 Introduction
The KVM HDMI over IP PoE Extender, UHD-4K allows HDMI & USB equipment to be connected up to
330ft (100m) over an Ethernet LAN, supporting 4K @ 30Hz (4:4:4) and 4K @ 60Hz (4:2:0) resolutions via
Cat5e/6 cable in multiple point-to-point and point-to-multipoint configurations. The Transmitter
(500772-TX) and Receiver (500772-RX) support PoE (PD) if used with a PoE (PSE) Ethernet Switch.
The Transmitter terminates to a computer server/workstation via a HDMI & USB port, The Receiver
terminates to a HDMI display and up to 4 USB devices such as a keyboard, mouse, printer, drawing pad,
storage device, camera, etc., via a 4 port USB hub. A single Receiver can be switched via hotkey
sequences to any Transmitter on the network, allowing a single operator to manage numerous
servers/workstations, in a distributed KVM application.
There are two hotkey methods to switch from one workstation to another. There is a Direct Switching
Method and an On Screen Display (OSD) Switching Method. This manual explains how to control the
switching from one workstation to another, as detailed below.
Key Features:
•One operator can manage multiple servers/workstations

2 Direct Switching Method
This method of switching from one workstation to another supports up to 16 workstations. It supports a
quick and simple method of switching to different workstations. If more than 16 workstations is
required, then the On Screen Display (OSD) Switching Method must be used.
Each Transmitter must have a unique Dip Switch setting (ranging from 0 to 15) which will automatically
correspond to the workstation ID. The Dip Switch represents a binary count as follows:
ID 0
ID1
ID 2
ID 3
ID 4
ID 5
ID 6
ID 7
ID 8
ID 9
ID 10
ID 11
ID 12
ID 13
ID 14
ID 15

To quickly switch from one workstation to another, say to switch from workstation ID 1 to workstation
ID 4, press and hold the “CTRL” key and while doing so quickly press “4” three times.
This will automatically switch the client operator to the workstation with ID 4.
Note that the hotkey keyboard mapping for ID 0 to ID 15 is as follows:
ID 0

3 On Screen Display (OSD) Switching Method
The OSD Switching Method does not rely on the Dip Switch setting and thus is not limited to only 16
workstations. This method supports 100’s of workstations.
To activate the OSD, quickly press “Scroll Lock” three times. This brings up the KVM OSD Menu, with a
pulldown tab to select from many workstations (scroll through the pulldown menu to select the desired
workstation). In addition, each KVM Transmitter can have a user defined alpha numeric name that is
representative of the attached workstation. For example the KVM Transmitter that is connected to the
main email server can have the name “Email Server 1” or “Main Email Server”.
The main KVM OSD Menu offers the operator a simple and clean menu selection as shown below. Note
that while the OSD is active, the operator is not connected to any workstation.
•Password Field: The user must enter his or her password in this field in order to login and be
provided system access. The default password is “admin”.
•Login: Type in a valid password and click on “Login”. If accepted, then access is granted.
•Logout: Click on “Logout”, to log out of the system. Access is denied while logged out.
•Node List: This field shows the previous workstation selected. When clicking on the pulldown
arrow, a listing of all workstations that may be selected for control is presented. Use the scroll
bar to view all workstations.
•Return: Returns control of the previous workstation (prior to bringing up the OSD).

•Connect: After selecting a workstation in the Node List, then pressing “Connect” provides
control over the selected workstation (assuming it is not already under the control of another
client).
•Refresh: Pressing “Refresh” updates the Node List of available workstations.
3.1 Login to the KVM Device
admin
Type in your password and click on Login with your mouse. The default password is “admin”.
The following screen will be displayed and is ready for you to select a workstation to connect with. Note
that the previously connected workstation is displayed by default in the Node List field.
3.2 Logout from the KVM Device
To Logout, simple click on “Logout”, and the login screen will be displayed. You will be required to login,
should you wish to take control of the KVM device and connect with available workstations.

3.3 Bring up the KVM OSD Menu
To bring up the KVM OSD Menu at any time, quickly press “Scroll Lock” three times. The OSD will be
displayed.
Note that this display is generated directly from the KVM Receiver, and is not being generated by any
workstation.
3.4 Selecting a Workstation to control
If the KVM OSD Menu is not currently being displayed, then do so at this time.
Before selecting a workstation to control, it is a good practice to click on “Refresh” first, just in case a
new workstation was recently added since the last time “Refresh” was executed.
To select a workstation, click on the dropdown arrow, as shown below, to list the workstations which
are controllable via the KVM device.
Note that the list includes the following information respectively:
•The Dip Switch setting selected on a given KVM Transmitter, where “CH0000”means Dip Switch
setting “0000”.
•The IP address of the KVM Transmitter.
The given name for the KVM Transmitter, which is generally a name that is representative of the
attached workstation.
Note: The KVM Transmitter name can be set via the web interface of the said KVM Transmitter.
To do so, follow the procedure in the section “Setting the Transmitter/Receiver Name”.

Page 9
To actually select a workstation to control, use the mouse to click on the desired workstation from the
provided “Node List”. Workstations that indicate a status of “Ready” are available for control, while
workstations that have a status of “Busy” are already being controlled by another client and are not
available to you at this time. Click on a free workstation to highlight it and then click on “Connect” to
connect with that workstation.
Once connected, the workstation screen will be displayed and the mouse and keyboard will function
normally, just as if you were directly connected and located next to the workstation.
Note: If you accidently try to connect to a workstation with a “Busy” status (meaning that it is already
connected to another client), then the KVM OSD Menu will return within a few seconds, rather than
presenting the operator with the workstation screen.
3.5 Returning
Clicking on “Return”, will return you to the previous workstation you were controlling. Note that if
another client connected to your previous workstation, while your OSD KVM Menu was active, then you
will not have access to this workstation until it is free, or instead you can simply connect with another
workstation that is currently free (in “Ready” state). Note that when you active the OSD, you lose
control of the workstation you were controlling.
3.6 Refresh
Pressing “Refresh” updates the Node List of available workstations. Note that during power up, a refresh
is automatically performed by the system.
