LED Functionality
KDS-EN7 and KDS-DEC7 LEDs function as follows:
A link is established between KDS-EN7 and KDS-DEC7 and is
transmitting A/V signals.
A signal is established, and a problem is detected.
No IP address is acquired.
A valid IP address has been acquired.
Flashes Green very fast (for 60sec)
A device identification command is sent (Flag me).
Device falls back to default IP address.
Security is blocking IP access.
On fallback address acquiring, device ‘ON’ LED flashes continuously in
slow 0.5/10sec cadence.
Device is in standby mode.
FW is downloaded in the background.
Flashes Green very fast (for 60sec)
A device identification command is sent (Flag me).
Device falls back to default IP address.
Security is blocking IP access.
Post reboot, all LEDs light for 3 seconds then return to their normal LED display mode.

Step 3: Mount KDS-EN7, KDS DEC7
Install KDS-EN7, KDS DEC7 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 http://www.kramerav.com/downloads/KDS-EN7).
• Mount the unit in a rack using the recommended rack adapter
(see http://www.kramerav.com/product/KDS-EN7).
• 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.
Step 4: Connect inputs and outputs
Always switch OFF the power on each device before connecting it to your KDS-EN7, KDS DEC7.
KDS-EN7 and KDS-DEC7 can stream 4K video, requiring a gigabit Ethernet switch for high quality performance, since the
maximum momentary transfer rate can reach 850Mbps. We recommend using AVoIP Ethernet switches that support: Multicast
forwarding or filtering, IGMP Snooping, IGMP Querier, IGMP snooping fast leave and Jumbo frame (8000 bytes or larger).
Connecting the audio input/output
To a balanced
stereo audio
source/acceptor:
To an unbalanced
stereo audio
acceptor:
To an unbalanced
stereo audio source:
To achieve specified extension distances, use the recommended Kramer cables available at http://www.kramerav.com/product/KDS-EN7.
Using third-party cables may cause damage!

Step 5: Connect power
By-default, the device uses PoE for powering the device.
Optionally, you can separately purchase a power adapter to connect to the product and plug into the mains electricity.
Safety Instructions (See www.kramerav.com for updated safety information)
Caution:
• For products with relay terminals and GPIO 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:
• 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 KDS-EN7, KDS DEC7
Allocating the IP Address via LCD screen menu
KDS-EN7 and KDS-DEC7 IP default addresses are: 192.168.1.39 for the Encoder and 192.168.1.40 for the Decoder. By
default, DHCP is enabled, and assigns an IP address to the device. If DHCP Server is not available, for example, in case a
device is connected directly to the laptop, that device gets the default IP address. If these IP addresses are already in use, the
system searches for a random unique IP in the range of 192.168.X.Y. the allocated IP address can be identified using the
LCD screen menu.
To allocate the IP address via LCD screen Menu:
1. Connect the device to the 24V DC power adapter and connect the adapter to the mains electricity. The ON LED lights
green, and the LINK LED flashes (indicating that no streaming activity is detected).
2. Use the Navigation button to view the assigned IP address on the LCD screen:
▪ DEV STATUS > LAN1 Status
▪ DEV STATUS > LAN2 Status (if the Service port connected as well).
Setting Channel Number
Each encoder requires a unique channel number, and the connected decoders should be tuned to that encoder channel. You
can set the channel number via the LCD screen menu or the embedded web pages.
To set the channel number for KDS-EN7 or KDS-DEC7 via the LCD screen menu:
1. Connect the device to the 24V DC power adapter and connect the adapter to the mains electricity. The ON LED lights
green, and the LINK LED flashes (indicating that no streaming activity is detected).
2. Change the channel number using the arrow buttons:
▪ In the LCD screen menu, go to DEV SETTINGS > CH DEFINE, set a unique channel number and press Enter to
save your selection.
▪ For each of the devices, set to the defined channel number.
To set the channel number via web pages:
1. Connect the Ethernet port to the network and power the device.
2. Access the embedded web pages.
3. In the KDS-EN7 Main page:
▪ Go to the AV Routing page.
▪ Select Channel ID and define the channel ID number.
4. In the KDS-DEC7 Main page:
▪ Go to the AV Routing page.
▪ Select the Channel ID corresponding to the desired encoder channel ID.
