LED
Color
Definition
LINK LED
Lights Green
A link is established between KDS-SW3-EN7 and the decoder is
transmitting A/V signals.
Flashes Green
A signal is established, and a problem is detected.
NET LED
Off
No IP address is acquired.
Lights Green
A valid IP address has been acquired.
Flashes Green very fast (for 60sec)
A device identification command is sent (Flag me).
Lights Yellow
No DHCP IP was assigned, so the device is using the fallback (default) IP
address, 192.168.1.39.
ON LED
Flashes Red
The default IP address is unavailable, and the device is acquiring a fallback
IP address in subnet 192.168.0.0/16.
The ON LED flashes continuously in a slow 0.5/10sec cadence.
Lights Green
When power is on.
Flashes Green fast
FW is downloaded in the background.
Flashes Green very fast (for 60sec)
A device identification command is sent (Flag me).
Lights Yellow
Device falls back to the default IP address.
Post reboot, all LEDs light for 3 seconds then return to their normal LED display mode.
Step 3: Mount KDS-SW3-EN7
Install KDS-SW3-EN7 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/KDS-SW3-EN7).
•Mount the unit in a rack using the recommended rack adapter
(see www.kramerav.com/product/KDS-SW3-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.
•Maximum mounting height for the device is 2 meters.

Step 4: Connect inputs and outputs
Always switch OFF the power on each device before connecting it to your KDS-SW3-EN7.
KDS-SW3-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).

To achieve specified extension distances, use the recommended Kramer cables available at www.kramerav.com/product/KDS-SW3-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-SW3-EN7
The KDS-SW3-EN7 default IP address is 192.168.1.39. By default, DHCP is enabled, and assigns an IP address to the
device. If DHCP Server is not available, for example, if a device is connected directly to a laptop, the device gets the default IP
address. If this IP address is already used, 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.
Viewing the IP address in the LCD screen Menu
1. Connect KDS-SW3-EN7 to a LAN switch with PoE (power over ethernet). The ON LED lights green.
2. Use the navigation button to view the assigned IP address on the LCD screen:
▪DEV STATUS > LAN1 Status (the Media port).
▪DEV STATUS > LAN2 Status (if the Service port is used).
Setting a Channel Number
Each encoder requires a unique channel number. All connected decoders must be tuned to the same channel.
Channel numbers can be set using the LCD screen menu or the embedded web pages.
Set the channel number in the LCD screen menu:
1. Connect the device to a LAN switch with PoE (power over ethernet). The ON LED lights green.
2. In the LCD screen menu, go to DEV SETTINGS > CH DEFINE.
3. Change channel number using the arrow buttons and set a unique channel number.
4. Press Enter to save your selection.
Set the channel number in the web pages
For information on using the web pages, see the KDS-SW3-EN7 user manual at https://www.kramerav.com/product/kds-
sw3-en7#Tab_Resources.
1. Connect KDS-SW3-EN7 to a LAN switch with PoE
(power over ethernet).
2. Open the embedded web pages; In the Main page (AV
Routing), Channel ID field, set a channel ID number.
Using KDS-SW3-EN7 for Dante or AES67 professional audio over LAN
AES67 is supported on KDS-SW3-EN7 devices running hardware version R:01 or higher
(the hardware version is on a label attached under the device, see the image on the right).
1. Download and install Dante Controller (see https://my.audinate.com/support/downloads/dante-controller).
2. If you are using AES67, also install AES67 Stream Monitor (https://aes67.app/download).
3. Open Dante Controller software on a laptop connected to the same LAN switch as KDS-SW3-EN7:
a. Double click the KDS-SW3-EN7 device in the Dante Controller screen (see below); The Device View screen
opens.
b. If using AES67, click the AES67 Config tab in the Device View and enable AES67 Mode; You will be prompted to
restart (“reboot”) the Dante Controller (double click the device again after restarting).
c. In the Device View’s Receive tab, select both channels and click “Create” to create an RTP multicast flow.
The RTP flow will be visible on the Transmit tab.
4. Open the KDS-SW3-EN7 webpages:
a. In the KDS-SW3-EN7 AV Settings page, open the Audio tab; Set Audio Source Mode to manual and Audio
Destination to Dante and LAN. Enter a Dante/AES-67 Name of your choice to identify the stream and SAVE.
b. In the KDS-SW3-EN7 Device Settings page, open the Network tab and set the Dante Port to Media (as shown
below) or to Service if you are using the Service LAN for Dante.
5. To monitor AES67 streams, use the AES67 Stream Monitor.
