Getting Started Installation Page Title The VGA KVM over IP Sender and Receiver units can either be connected over a Local Area Network (LAN) or they can be directly connected to one another. Using a Direct Connection By default, the VGA KVM over IP is shipped in Auto IP mode. In Auto IP mode, each Sender and Receiver unit assigns itself a unique IP address within the range of 169.254.x.x. Auto IP mode is only used when Sender and Receiver units are directly connected to one another.
Getting Started Installation 4. See Supplementary Connections for instruction on connecting USB, IR, RS-232, and audio cables. 5. Connect the included 5V DC locking power supplies to the Sender unit and Receiver unit. Do not overtighten the locking connectors. Connect the included AC power cords from the power supplies to available electrical outlets. 6. After a few moments, the VGA source will be displayed.
Getting Started Installation Local Area Network (LAN) Connection IMPORTANT: The use of a Gigabit switch with 8K “jumbo frame” capability is required when connecting the VGA KVM over IP to a network. In order to connect the VGA KVM over IP to a Local Area Network (LAN), both the Sender and Receiver unit must first be set to DHCP mode or static IP mode. 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.

Local IP = Receiver unit Channel: 01 Trying to find the gateway... FW: V1.31V-Nov-08 779c Local IP: 169.254.7.70 Remote IP: 169.254.6.113 ID: 825E3744F261 Remote IP = Sender unit 4.
Chapter Page Title 5. To upgrade the firmware to a limited number of channels, refer to Upgrading the Firmware for more information.
Operating the VGA KVM over IP Basic Operation Setting the IP Mode The VGA KVM over IP can be set to Auto IP, DHCP, or Static IP mode. By default, the VGA KVM over IP is shipped in Auto IP mode. 1. Access the Web interface by entering the IP address of the desired Sender or Receiver unit. Refer to Displaying the IP Address if necessary. 2. Click the Network tab. The current IP Mode will be highlighted within the IP Setup window group. In the illustration below, Auto IP button is highlighted. 3.
Operating the VGA KVM over IP Basic Operation Setting the Video Channel In order a Sender and Receiver unit to communicate with one another, they must both be set to the same channel. This is similar to changing the channel on a cable or satellite box in order to view a different program. By default, all Sender and Receiver units are set to channel 0. NOTE: When connecting Sender and Receiver units, it is highly recommend that the video channel for each unit is set to a channel other than 0.
Operating the VGA KVM over IP Basic Operation Enabling or Disabling Video over IP This feature is useful for masking video. Disabling the video on the Sender unit will mask the video on all connected Receiver units (multicast mode only). To mask the video on selected Receiver units, disable the video on the desired Receiver units. 1. Access the Web interface by entering the IP address of the desired Sender or Receiver unit. Refer to Displaying the IP Address if necessary. 2. Click the Functions tab. 3.
Operating the VGA KVM over IP Unicast and Multicast Modes Configuring Unicast Mode The term unicast is used to describe a configuration 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 unicast mode, the VGA KVM over IP functions similar to a VGA KVM switcher.
Operating the VGA KVM over IP Unicast and Multicast Modes 3. Click the Unicast button under the Network Mode group. When selected, the Unicast button will be highlighted in blue. 4. Click the Save button in the lower-right corner of the Network Mode group. 5. The following message will be displayed, at the top of the page, indicating that the casting mode has been applied to the Sender or Receiver unit. 6. Click the Reboot button near the bottom portion of the page to apply the changes. 7.
Operating the VGA KVM over IP Unicast and Multicast Modes Switching between Sender units in Unicast mode When multiple Sender and Receiver unit are used in unicast mode, the VGA KVM over IP behaves as a switcher. In unicast mode, a Sender unit can communicate with only one Receiver unit at a time. In the example below, we will switch Receiver unit R1 to receive the VGA source on Sender unit S1. Figure 2.2 - Unicast mode: Receiver unit R1 is connected to Sender unit S2.
Operating the VGA KVM over IP Unicast and Multicast Modes Figure 2.3 - Unicast mode: Receiver unit R1 is now connected to Sender unit S1. Receiver unit VGA Out 2 LAN R 2 Sender unit Receiver unit 5 S 2 R 3 VGA Out 1 Sender unit VGA In S 2 1 Sender unit 5 VGA In 1 S VGA In Note that each of the Sender units in Figure 2.3 is assigned a unique channel number.
Operating the VGA KVM over IP Unicast and Multicast Modes In order to solve the problem, in Figure 2.4, we would need to make sure that each of the Sender units is set to a unique channel number. 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. The VGA KVM over IP can be used with up to 256 Sender units to provide switching capability between each Receiver unit.
Operating the VGA KVM over IP Unicast and Multicast Modes Configuring Multicast Mode The term multicast is used to describe a configuration 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.
Operating the VGA KVM over IP Unicast and Multicast Modes 3. Click the Multicast button under the Network Mode group. When selected, the Multicast button will be highlighted in blue. 4. Click the Save button in the lower-right corner of the Network Mode group. The following message will be displayed, at the top of the page, indicating that the casting mode has been applied to the Sender or Receiver unit. If a display is connected to the Receiver unit, then the message “Starting USB” will be displayed.
Operating the VGA KVM over IP Using RS-232 The VGA KVM over IP supports RS-232 pass-through, allowing the control of remote RS-232 devices. The Sender and Receiver unit which are being used to pass-through the RS-232 data must be set to the same baud rate as the RS-232 host and client. In the example below, the Gefen 4x1 VGA Switcher w/ Audio Decoding (Gefen part no. GTV-AUDDEC-N) has been connected to Receiver unit A. This is the RS-232 client.
Operating the VGA KVM over IP Using RS-232 1. Access the Web interface for the Sender unit. 2. Click the Functions tab. 3. Locate the Serial over IP group and change the RS-232 settings to match the settings of the RS-232 device that is being used. In this case, we need to use the settings from Table 2.1 4. Make sure that the Enable Serial over IP box is checked. NOTE: If Enable Serial over IP is not checked, then RS-232 pass-through will be disabled. 5.
Operating the VGA KVM over IP Using RS-232 RS-232 under Unicast Mode In unicast mode, a Sender unit will be able to communicate with only one Receiver unit at a time. Figure 2.7 - In unicast mode, the host can talk to only one RS-232 device at a time.
Operating the VGA KVM over IP USB Control USB under Unicast Mode When connecting USB devices to the VGA KVM over IP, the functionality is similar to that of video and RS-232. NOTE: By default, the VGA KVM over IP Sender and Receiver units are shipped in unicast mode. As an example, we will start with our original diagram and connect a computer to Sender unit S2 and a keyboard and mouse device to Receiver unit R2. This will allow us to control the computer from the Receiver unit. Figure 2.
Operating the VGA KVM over IP USB Control 4. Locate the USB over IP group and make sure the Enable USB over IP box is checked. This is the default setting. 5. In unicast mode, the Operation Mode is automatically set to Active on link and cannot be changed. 6. Make sure that the USB Mouse Mode is set to High Resolution. This is the default setting. Use Compatibility mode only if using additional KVM switchers or other devices within the system that cause the mouse to behave erratically. 7.
Operating the VGA KVM over IP USB Control USB under Multicast Mode When connecting USB devices to the VGA KVM over IP, the functionality is similar to that of video and RS-232. There are two USB modes available in multicast mode: Active per request mode and Active on link mode. For an example, we’ll begin with the last diagram and connect another keyboard and mouse device to Receiver R1. This will allow us to control the computer from two separate locations. Figure 2.
Operating the VGA KVM over IP USB Control In multicast mode, the Operation Mode for both Sender and Receiver units are automatically set to Active per request mode. Under Active per request mode, multiple USB devices may be present on one or more Receiver units. However, only one Receiver unit can have USB control at a time. By default, the first Receiver unit connected to the system will have USB control.
Operating the VGA KVM over IP USB Control Assigning USB control under Active per request mode 1. Press and hold the Switch button on the desired Receiver unit, for at least two seconds. In this example, we will depress the Switch button on Receiver unit R1. 2. The message “Starting USB” will appear on the connected display. Figure 2.11 - Receiver unit R1 has USB control.
Operating the VGA KVM over IP USB Control Active on link mode Under Active on link mode, a maximum of four USB devices can be used within a system. In the diagram, on the previous page, the system is already using the maximum number of USB devices (2 USB devices per Receiver). If we had two more Receiver units (making a total of four Receiver units), we could have connected a single USB device to each Receiver unit. To switch to Active on link mode, follow the instruction below. 1.
Operating the VGA KVM over IP EDID Management The VGA 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 sent by each source. By default, the (downstream) EDID from the display, connected to the Receiver unit, is used.
Operating the VGA KVM over IP EDID Management Using the Downstream EDID By default, the (downstream) EDID from the display, connected to the Receiver unit, is used. If the internal EDID is being used (see Using the Internal VGA EDID), then use the following procedure to revert to the downstream EDID. 1. Access the Web interface for the Receiver unit. 2. Click the Functions tab. 3. Make sure that the Copy EDID of Connected Display box is checked. This is the default setting.
Operating the VGA KVM over IP Audio Connections Audio works in both unicast and multicast modes. The only difference between the two modes is that the Mic In jack is automatically disabled, on all Receiver units, in multicast mode. To illustrate how audio works with the VGA KVM over IP, we will set up a microphone and some speakers. 1. Our computer has a Line In jack, as part of the sound card and we want to be able to access this jack from the Receiver unit.
Operating the VGA KVM over IP Audio Connections Finally, we’ll connect a set of powered computer speakers to the Line Out jack on the Receiver unit. Connect to computer speakers In the diagram below, the mouse and keyboard USB devices have been removed from Sender unit S2 and Receiver unit R2, for purposes of clarity. Arrowheads indicate the audio signal path. Figure 2.12 - Speaker and microphone connections in unicast mode.
Operating the VGA KVM over IP Audio Connections Figure 2.13 - The Mic In jack, on all Receiver units, is automatically disabled in multicast mode.
