  • Page 17: Installation

    Getting Started Installation The DVI KVM over IP Sender and Receiver units can either be connected over a Local Area Network or they can be directly connected to one another. Connecting to a Local Area Network (LAN) Connect a CAT-5e (or better) cable between the Link jack on the Sender unit and your LAN connection, via a switch or router. Connect any one of the three Ethernet ports on the Receiver unit to the LAN. Although any of the Ethernet ports can be used, it is recommended to use Ethernet port 1 for connecting the Receiver unit to the LAN, in order to easily identify this as the “LAN cable”. Connect any additional IP-based devices or daisy-chain additional Receiver units to Ethernet ports 2 and 3. Connect to router or switch Sender unit Connect to other Connect to LAN Receivers / IP devices Receiver unit Direct Connection Connect a CAT-5e (or better) cable from the Link jack on the Sender unit to the Ethernet 1 jack on the Receiver unit. Although you can connect the CAT-5e cable to any of the three Ethernet ports, it is recommended that Ethernet 1 is used for the first connection. This leaves Ethernet port 2 and 3 open for connecting additional devices or when daisy-chaining Receiver units. (continued on next page) page | 7...

  • Page 22: The Linking Process

    Operating the DVI KVM over IP The Linking Process By default, the DVI KVM over IP is shipped in DHCP mode. DHCP mode should work in most cases, since the Sender and Receiver units are assigned an IP address by the DHCP server or router. After all the connections have been made, the DVI KVM over IP will attempt to establish a connection between the Sender and Receiver unit. NOTE: When directly connecting the Sender and Receiver units, both the Sender and Receiver unit must be set to Auto IP mode. See Configuring Auto IP Mode for information. During this time,, the Link LED on both the Sender and Receiver unit will begin to flash and the message “Trying to find the gateway” will be displayed on the screen. FW: 12-Dec-24 b6e4 Local IP: 192.168.1.8 Remote IP: 192.168.1.9 Trying to find the gateway... ID: 82B9969C6B9E Once a successful connection is established, the Link LED on the Sender and Receiver unit(s) will glow bright green and the source signal will appear on the display.

  • Page 23: Network Configuration

    Operating the DVI KVM over IP Network Configuration If DHCP mode is not desired, the DVI KVM over IP can also be set to Auto IP mode or Static IP mode. In order to change the network options, both the Sender and Receiver unit contain a built-in Web interface. Changing the network settings may also be necessary when using multiple Sender and Receiver units. Accessing the Web Interface Connect an Ethernet cable from a computer to the network on which the DVI KVM over IP is connected. Identify the IP address of both the Sender and Receiver unit. This can be done by viewing the display, during the linking process. If the Sender and Receiver units are already displaying a picture and the IP addresses are not known, switch the video channel on the Receiver unit to display the IP information. See Setting the Video Channel for information on how to switch the video channel.

  • Page 25: Configuring Auto Ip Mode

    Operating the DVI KVM over IP Network Configuration Configuring Auto IP Mode Auto IP mode is used when there is no DHCP server (or router) available and each Sender and Receiver unit is connected to a switch. When set to Auto IP mode, the Sender and Receiver unit will self-assign unique IP addresses (within the range of 169.254.x.x). Use this mode when the Sender and Receiver unit are directly connected. Access the Web interface of the Sender (host) unit by entering the IP address of the Sender unit in a Web browser. Once the Web page is displayed, click the Utilities bar to expand it.

  • Page 27 Operating the DVI KVM over IP Network Configuration Although this message will be presented when there is an error in the command line, it is important to understand that this also occurs after the network mode has been changed. This is because the IP address has changed and the Web page can no longer access the current IP address of the Sender (or Receiver) unit. Once the process has completed, the new IP address will appear on the display, as shown below: FW: 12-Dec-24 b6e4 Local IP: 192.168.1.8 Remote IP: 169.254.7.8 Trying to find the gateway... ID: 82B9969C6B9E New IP address The new IP address of the Sender unit is no longer in the same subnet as the Receiver unit. Therefore, the Sender unit will not be able to communicate with the Receiver unit until the Receiver unit is also set to Auto IP mode. Repeat steps 1 through 7 for the Receiver unit. 10. Once both units are configured for Auto IP mode, video communication will be restored.

  • Page 28: Changing Network Settings On The Computer

    Operating the DVI KVM over IP Network Configuration Changing Network Settings on the Computer We just finished configuring the Sender and Receiver units to Auto IP mode. In order to configure these units for Static IP mode (or to return to DHCP mode), we will need to configure each unit separately. However, because we are no longer using DHCP to assign IP addresses, we will need to modify our network settings to match those of the Sender and Receiver units. Let’s continue from our previous example. First, we will identify the current IP settings for our Sender and Receiver unit. Once again, if the Sender and Receiver units are already displaying a picture, switch the channel on the Receiver unit to display the IP information. See Setting the Video Channel for information on how to switch the video channel on the Receiver unit. FW: 12-Dec-24 b6e4 Local IP: 169.254.7.11 Remote IP: 169.254.7.8 Trying to find the gateway... ID: 82B9969C6B9E As we can see in the illustration, above, the IP addresses for the Sender and Receiver unit are 169.254.7.8 and 169.254.7.11, respectively. Therefore, we must change our computer’s IP address so that it falls within the same subnet...

In our example, the IP address for the Sender unit is 169.254.7.8 11. The Sender unit page will now be displayed. Because we have already configured the IP address for the computer that will be accessing the Web page for the Sender unit, we can also access the Receiver unit. 12. To access the Receiver unit, disconnect the network cable from the Receiver unit and connect the computer directly to the Receiver unit. Once the computer is connected, enter the IP address of the Receiver unit to access the Web interface on the Receiver unit. As long as the Sender and Receiver units are within the same address range, this procedure only needs to be performed once. 13. We can now proceed to change the network configuration to Static IP mode or DHCP mode. See the next page for details on configuring Static IP Mode and DHCP mode. page | 21...

  • Page 32: Configuring Static Ip Mode

    Operating the DVI KVM over IP Network Configuration Configuring Static IP Mode Access the Web interface of the Sender (host) unit by entering the IP address of the Sender (or Receiver) unit in a Web browser. See Accessing the Web Interface. Once the Web page is displayed, click the Utilities bar to expand it. Click the Console API Commmand text box and type the following command line (all on one line). Make sure to replace the IP address (192.168.1.100) and the net mask (255.255.255.0) with the desired values. astparam s ip_mode static; astparam s ipaddr 192.168.1.100; astparam s netmask 255.255.255.0; astparam save; reboot Click the Apply button. Configuring DHCP Mode As stated earlier, the DVI KVM over IP ships in DHCP mode. In order to return to DHCP mode, use the following procedure: Access the Web interface of the Sender (host) unit by entering the IP address of the Sender (or Receiver) unit in a Web browser. See Accessing the Web Interface.

  • Page 33: Setting The Video Channel

    Operating the DVI KVM over IP Setting the Video Channel In order for the Receiver unit to acquire the desired source (connected to the Sender unit), the Sender and Receiver unit(s) must be set to the same channel. It’s very similar to changing the channel on a cable box or television. This applies when using both multiple and single Sender units. By default, the Sender and Receiver units are set to channel 0 (zero). We will use the illustration below as an example and assign channel 02 to both a Sender and Receiver unit. Receiver unit Channel:02 DVI Out Sender unit Channel:03 Receiver unit No signal Channel:06 Sender unit Channel:02 DVI In Sender unit Channel:05 DVI In DVI In On the bottom of each Sender unit (see page 4), is a 16-position rotary switch.
  • Page 34 Operating the DVI KVM over IP Setting the Video Channel Reboot the Sender unit for the channel-change to take effect. Rebooting the Sender unit (or the Receiver unit) can be performed in one of three ways: 1) Disconnect and reconnect the power supply. 2) Click the Reboot button on the Web interface. 3) Type reboot in the Console API Command text box and click the Apply button. Press the Switch button on the front panel of the Receiver unit. Switch button The current channel will be displayed. In this example, we will assume that the Receiver channel is currently set to channel 0. Because the Receiver unit is not set to the same channel as the Sender unit, the source signal is not displayed.

  • Page 35 Operating the DVI KVM over IP Setting the Video Channel Once the current channel is displayed, consecutively press the Switch button on the front panel of the Receiver unit until “Channel 02” is displayed. If the channel is not changed within a specific amount of time, the current channel setting will disappear from the screen. If this is the case, press the Switch button once to display the current channel. TIP: The current channel of the Receiver unit can always be displayed, without changing the channel, by pressing the Switch button once. After a few moments, the source signal will appear on the display. Channel:02 We can see from our example that since both the Sender and Receiver unit have been set to channel 02, the source is being displayed. However, the other Receiver unit, in the illustration on page 23, is set to Channel 06. This Receiver unit will not receive any video data unless one of the remaining two Sender units is set to channel 06. NOTE: The DVI KVM over IP can be used with up to 16 Sender units to provide switching capability between each Receiver unit. Up to 256 Receiver units are supported. Each Receiver unit can be set to receive video data from any one of 16 Sender units. page | 25...

  • Page 36: Unicast And Multicast Modes

    Operating the DVI KVM over IP Unicast and Multicast Modes The DVI KVM over IP has two operating modes: Unicast and multicast. In unicast mode, only a single Receiver unit can display video using multiple (or a single) Sender unit on the same network. In Multicast mode, multiple Receiver units can receive signals from multiple (or a single) Sender unit on the same network. By default, the DVI KVM over IP is shipped in unicast mode. Configuring Unicast Mode NOTE: As mentioned earlier, the DVI KVM over IP is shipped in unicast mode. If the units are configured in multicast mode, the following procedure will not need to be performed after unpacking and connecting the product. To illustrate an example of how unicast mode works, we will use the following diagram. We have arbitrarily set up three Sender units and two Receiver units. For reference, we will identify the Sender units as 1 through 3 and the Receiver units A and B. Receiver unit DVI Out Sender unit DVI Out Receiver unit Sender unit...

Repeat steps 1 through 6 for each Sender and Receiver on the network. Now that each device has been configured, we need to specify which channels will be used by each Sender and Receiver unit. It is important to note that when using unicast mode, that only one Receiver can display video at a time from the selected channel. Let’s illustrate this using our original diagram. We’ve added some numbers in red to denote which channels are being used by each Sender and Receiver. The channel numbers are arbitrary. Receiver unit Sender unit Receiver unit Sender unit DVI In Sender unit DVI In DVI In In this example above, Receiver unit B is set to channel 02 and Receiver A is set to channel 03. Sender unit 3 is also set to channel 02. As expected, the source signal (indicated by the red line) from Sender unit 3 appears on the display connected to Receiver unit B.

  • Page 40: Switching Between Displays In Unicast Mode

    Operating the DVI KVM over IP Unicast and Multicast Modes Switching between displays in Unicast mode In order to control which display receives the source signal, press the Switch button on the Receiver unit to change the channel. For example, let’s say we want to send the DVI source to Receiver unit A. Receiver unit Sender unit Receiver unit Sender unit DVI In Sender unit DVI In DVI In Press the Switch button on Receiver unit A and set the channel to 02. At this point, both Receiver unit A and Receiver unit B are set to channel 02. However, because the DVI KVM over IP is in unicast mode, only one Receiver can display the source signal (from a Sender unit) at a time. Since Receiver unit B was set to channel 02, first, Receiver unit B has priority and will continue to receive the source signal until its channel is changed.

  • Page 43: Using Rs-232

    Operating the DVI KVM over IP Unicast and Multicast Modes Using RS-232 The DVI KVM over IP supports RS-232 pass-through, allowing the control of remote RS-232 devices (near the Receiver unit) from the source (Sender unit) location. The RS-232 host (controller) and device (client) must be set to the same baud rate. In addition, the correct baud rate must be set on the Sender and Receiver units which are being used to control the RS-232 client. In the example below, the Gefen 4x1 HD Switch w/ Audio Decoding (Gefen part no. GTV-AUDDEC-N) has been connected to Receiver unit A. This is the RS-232 client. We want to control this product from Sender unit 3, using a laptop PC (RS-232 host). We have arbitrarily assigned channel 12 to both the Sender and associated Receiver unit.

    Operating the DVI KVM over IP Unicast and Multicast Modes USB Control When connecting USB devices to the DVI KVM over IP, the functionality is similar to that of video and RS-232. As an example, we will connect a computer to the Sender unit 2 and a mouse device to Receiver unit B. Since we are connecting a USB (mouse) device to only one of the Receiver units, it does not matter whether we are in unicast or multicast mode. Connect the USB host device to the Sender unit. Connect up to two USB devices to the Receiver unit(s). The mouse device can now be used to control the computer that is connected to Sender unit 2.

  • Page 48: Audio Input And Output

    Operating the DVI KVM over IP Unicast and Multicast Modes ► Unicast Mode In unicast mode, only a single Receiver unit will be able to communicate with a Sender unit. However, multiple USB devices can be connected to multiple Receiver units. Use the Switch button to change channels to the desired Receiver unit. ► Multicast Mode In multicast mode, the USB host device can be controlled from multiple Receiver units at one time. When using multicast mode, the Switch button must be pressed on each Receiver unit in order to enable USB on each Receiver unit. In multicast mode, the DVI KVM over IP behaves like a USB hub. Connecting multiple mouse / keyboard devices to each Receiver unit makes little sense if multiple users are attempting to control the same computer. However, if different USB devices are connected, each remote station (Receiver unit) can use a USB device without interference. Audio Input and Output To illustrate how audio works with the DVI KVM over IP, we will set up a microphone and some speakers. Since we already have a mouse device connected to our computer, we will continue using the setup illustrated on the previous page. The Sender and Receiver unit are set to unicast mode. Our computer has a Mic In jack, as part of the sound card. However, we want to be able to access this jack from the Receiver unit. Therefore, connect the microphone to the Mic In jack on the Receiver unit.
  • Page 49 Operating the DVI KVM over IP Unicast and Multicast Modes WARNING: DO NOT connect the cable from the Line Out jack on the Sender unit to the Mic In jack on the computer. Doing so will result in audio “clipping” and may cause damage to the sound card. Connect to Line Out on computer Sender unit Connect to Line In on computer NOTE: When using HDMI sources with an HDMI-to-DVI adapter, the HDMI audio will be passed through to the DVI Out connector. However, if a 3.5mm-to-3.5mm mini-stereo cable is connected to the Line In jack on the Sender unit, the embedded HDMI audio is switched off. This allows the audio signal from the Line In jack (Sender unit) to be received on the Line Out jack (Receiver unit). Now let’s connect another 3.5mm-to-3.5mm mini-stereo cable between the Line Out jack on the computer and the Line In jack on the Sender unit. Finally, we’ll connect our computer speakers to the Line Out jack on the Receiver unit. Connect to computer speakers page | 39...

Note that in the diagram, below, we have indicated (using the dashed line) that either the computer or an MP3 player (e.g. iPod, etc.) can be connected to the Line In jack on the Sender unit. Of course, if another device is connected to the Line In jack on the Sender unit (instead of the computer), then the audio signal coming from the microphone will not be heard.

  • Page 53: Edid Management

    Operating the DVI KVM over IP EDID Management The DVI KVM over IP features EDID Management. Before the source can send video (and/or audio) data, the source device (connected to each Sender unit) reads the EDID (Extended Display Identification Data) from the displays which are connected to each Receiver unit. The EDID contains information about what type of audio/video data can be accepted from the source. By default, the internal DVI EDID (stored in the Sender unit) is used. However, a downstream EDID (from a display, etc) can be retrieved and stored in the Sender unit. Storing a Downstream EDID For this example, we will use our original set up. We are currently using the default DVI EDID but now we want Display A to use the same EDID as Display B.
