Step 3: Mount KIT-500
Install KIT-500 using one of the following methods:
• Attach the rubber feet and place the unit on a flat surface.
• Fasten a bracket (included) on each side of the unit and attach it to a flat surface
(see www.kramerav.com/downloads/KIT-500).
• Mount the unit in a rack using the recommended rack adapter
(see www.kramerav.com/product/KIT-500).
• Ensure that the environment (e.g., maximum ambient temperature &
air flow) is compatible for the device.
• Avoid uneven mechanical loading.
• Appropriate consideration of equipment nameplate ratings should be
used for avoiding overloading of the circuits.
• Reliable earthing of rack-mounted equipment should be maintained.
• Maximum mounting height for the device is 2 meters.
Step 4: Connect inputs and outputs

Connecting the audio output
Wiring the RJ-45 connectors
To a balanced
stereo audio
acceptor:
This section defines the TP pinout, using
a straight pin-to-pin cable with RJ-45
connectors.
To an unbalanced
stereo audio
acceptor:
For HDBT cables, it is recommended
that the cable ground shielding be
connected/soldered to the connector
shield.
To achieve specified extension distances, use the recommended Kramer cables available at www.kramerav.com/product/KIT-400.
Using third-party cables may cause damage!
Step 5: Connect power
To power the devices:
1. Set the PoC switches to ON on both
devices.
2. Connect the power adapter to one of the
devices (KIT-500T or KIT-500R).
Safety Instructions (See www.kramerav.com for updated safety information)
Caution:
• For products with relay terminals and GPI\O ports, please refer to the permitted rating for
an external connection, located next to the terminal or in the User Manual.
• There are no operator serviceable parts inside the unit.
Warning:
• Failure to use PoC and power connector correctly may destroy the devices!
• Use only the power cord that is supplied with the unit.
Disconnect the power and unplug the unit from the wall before installing.
Step 6: Operate KIT-500
Operate KIT-500 via:
• Front panel buttons
• Remotely, by RS-232
serial commands
transmitted by a touch
screen system, PC, or
other serial controller
• Embedded web
pages via the
Ethernet
• Remote control
switches.
• Room Automation
Panel.
RS-232 Control / Protocol 3000
Example: (Set the Audio out volume level to 75): #AUD-LVL 1,1,75
Default IP Parameters – DHCP ON
Default EDID Native
Resolution
4K@60 4:4:4
In the case that the HDMI display connected to KIT-500T
does not support 4K60 4:4:4, copy your current EDID
display to KIT-500T’s inputs.
Operating via the remote control switches
Momentarily connect the desired pin to the GND pin to select an input:
One button toggles between display on and display
off (instead of using two separate buttons for on and
off). Alternatively, using the KIT-500R OSD,
configure turning the display on or off according to
whether a switch is open or closed (for example,
when using an occupancy sensor).
