The Gen 2.0 KVM over IP Sender and Receiver units can be connected directly or through a

Local Area Network (LAN). Both installations will be covered.

Local Area Network (LAN) Connection

When connecting the Sender and Receiver units to a Local Area Network (LAN), DHCP, static,

or APIPA (Automatic Private IP Addressing) IP modes can be used. DHCP mode will use the

DHCP server to automatically assign an IP address for each Sender and Receiver unit that

is connected to the network. Static IP mode will allow the IP address for each Sender and

Receiver unit to be congured manually. Contact your network administrator if necessary.

APIAP mode assigns a class-B IP address, in the 169.254.x.x range, to the Sender and

Receiver units, if a DHCP server is not available.

1. Connect a CAT-5e (or better) cable between the LAN (PoE) port on the Sender unit and a

Gigabit PoE-enabled IP switch.

2. Connect LAN 2 (PoE) on the Receiver unit to the same network switch. Each cable run can

be up to 330 feet (100 meters).

3. If NOT USING A PoE-compliant switch, then connect the included 5V DC power supplies

to the Sender and Receiver units.

Installation

Important

If the IP switch is PoE-compliant and the Sender and Receiver are connected

through their PoE ports, external power supplies will not be required. However,

additional Receivers or other devices connected to the LAN 1 port of a Receiver will

require an external power supply.

Unicast & Multicast Modes

Conguring Unicast Mode

The term unicast is used to describe a conguration where information is sent from one point

to another point. It is possible to have multiple Sender and Receiver units connected in a

system. However, in unicast mode a Sender unit can communicate with only one Receiver unit

at a time. In mode, the Gefen AV over IP products function similar to a KVM switcher.unicast

The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units

(R1 and R2) on a network, operating in unicast mode. The video channels are notated

in blue.

Figure 2.1 - Unicast mode: A Sender unit can communicate with only one Receiver unit at a time.

1. Access the Web interface for each Sender and Receiver unit that will be using unicast

mode. In this example, we will start with Receiver unit R1.

2. Login as “Administrator”.

Tip

In unicast mode, the Gefen AV over IP Senders and Receivers function as a KVM

switcher.

Unicast & Multicast Modes

Switching between Sender units in Unicast mode

When multiple Sender and Receiver unit are used in mode, the Gefen AV over IP Sender unicast

and Receivers behave as a switcher. In mode, a unicast Sender unit can communicate with only

one Receiver unit at a time.

In the example below, Receiver unit R1 will be switched to receive the source connected to

Sender unit S1. To do this, simply change the video channel.

Figure 2.2 - Unicast mode: Receiver unit R1 is connected to Sender unit S2.

1. Access the Web interface for Receiver unit R1.

2. Login as “Administrator”.

3. Click the tab and change the video channel. Refer to Network Setting the Video

Channel (page 27) if necessary.

4. Click the button.Apply

5. The following message will be displayed, at the top of the page, indicating that the

new channel has been applied to the Sender or Receiver unit.

Unicast & Multicast Modes

Figure 2.3 - Unicast mode: Receiver unit R1 is now connected to Sender unit S1.

Now, observe the result when both Sender S1 and S2 are set to channel 5:

Figure 2.4 - Unicast mode : Two Sender units (S1 and S2) using the same violation

video channel.

In this example, Receiver R1 will continue to receive audio/video data from Sender

S1, even though Sender S2 is set to the same channel. The reason for this is

because Receiver R1 and Sender S1 were already set to the same channel and

communicating (as depicted in Figure 2.3). However, this scenario violates the

unicast mode rule: A Sender unit can communicate with only one Receiver unit

at a time.

Unicast & Multicast Modes

When using unicast mode, each of the Sender units must be assigned a unique

channel and should never be changed. Use the Receiver unit to switch (channels)

between Sender units.

Note

In unicast mode, if an additional Sender unit is introduced into a system with the

same channel as another Sender unit, then the Receiver unit will continue to receive

audio/video data from the Sender unit which was connected rst.

Conguring Multicast Mode

The term multicast is used to describe a conguration where information is sent from one or

more points to a set of other points. For example, a single Sender unit can transmit data to

multiple Receiver units. In addition, if multiple Sender units are used, each Sender unit can

transmit data to any Receiver that is not already receiving data from another Sender unit.

In multicast mode, the Senders and Receivers function similar to a KVM matrix.

The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units

(R1 and R2) on a network, operating in multicast mode. The video channels are shown

in blue.

Audio Sources and De-Embedding

The following outlines the audio de-embedding functionality of this product.

• If a 3.5mm mini-stereo cable is connected to the port on the HDMI or Line In

DisplayPort™ Sender unit, then the HDMI or DisplayPort™ audio will be disabled on the

Receiver unit. The port, on the Receiver unit, will output audio from the source Line Out

connected to the Line In port on the Sender unit.

• When a source is connected to the port on the Sender unit, the audio will be Line In

heard on the HDMI Out or DisplayPort™ Out, , Line Out Opt Out Coax Out, and ports.

• The port on the Receiver unit will only pass audio to the port on the Line In Line Out

Sender unit when in .unicast mode

• The port will de-embed both 2-channel PCM and Bitstream (up to 5.1 Opt Out

channel) audio from the HDMI In or DisplayPort™ In port. High-resolution (lossless)

audio will not be outputted.

5. Under the Wall Size and Position Layout window group, click the drop-down lists for the

Vertical Monitor Count Horizontal Monitor Count and and select the number of rows

and columns of displays, respectively.

6. Select the row and column positions using the Row Position Column Position and drop-

down lists. Both row and column positions begin with a reference value of zero.

7. Click the drop-down list, next to the Apply button, to select the desired host or client to

which these settings will be applied.

If the option is selected, then all parameters will be transferred to all Receiver units. All

For monitor count and bezel compensation in a video wall array of matching displays,

this is ne, but the row and position will also be copied. There is an option for “This” unit

that will apply to the current unit being interfaced with. The “This” option can be used

to precisely set the proper position of each unit but would require the user to access

the web interface of each unit to set. Alternatively, the drop-down will provide a list of

all connected host (Sender units) and clients (Receiver units). This process allows the

conguration of an entire video wall from a single unit.
