Page 92: Configuring Network Settings
When shipped, the X75HD is configured with a default IP address along with other network settings. If you intend to control the unit remotely or connect it to a network hub/switch along with other X75HD units, you will need to reconfigure the IP with unique network settings.
Page 93: Making Required Hardware Connections
If you are connecting an X75HD directly to a PC (no network Note connection), connect one end of a cross-over Ethernet cable to the CTRL/STRM RJ-45 port on the back of the X75HD, and the other end The RJ-45 connector labelled to the PC Ethernet port. See Figure 5-1.
Page 94: Setting Ip And Subnet Mask Addresses
To allow devices to communicate on a network, you need to set all devices to the same subnet (network location). When shipped, all X75HD units are configured with the same default IP (device identifier) and subnet addresses. These addresses need to be changed so that each unit is uniquely identified and the network location of all units is accurately reflected.
Page 95 Setting the IP Address of a Single Unit Follow these steps to configure X75HD IP and subnet mask addresses: 1. Apply power (plug in) an X75HD unit with a frame-mounted local control panel (LCP). When ready for configuration, the X75HD main menu shows on the display screen.
Page 96 “Remotely Controlling X75HD Systems” on page 73 for more information on RCP configuration. 6. Connect all X75HD systems and remote panels to a network hub or switch using a 10/100Base-T Ethernet cable. 7. Ensure that all configured X75HD units are detected on the Note network.
Page 97: Remotely Controlling X75Hd Systems
Manual for more information on using an RCP-X75 remote control panel. Preparing for Remote Control via RCP You can remotely control X75HD units over a network from a remote Note control panel. RCP-X75 panels remotely control X75HD units via broadcast. Switchers and routers in the network need to be configured A frame-mounted local control accordingly.

An asterisks (*) beside an IP address indicates that this is the remote system currently being controlled by the panel. 3. Use the control knob to scroll through the list of available X75HD devices, highlight the unit you wish to control, and then press Enter.
Page 99 Using a Frame-Mounted Local Control Panel for Remote Operation After ensuring that all connections and network settings have been made, you can also remotely control X75HD units that are on the network using a frame-mounted local control panel (LCP). To do this, click Remote on the LCP to enter Remote mode, and to view the list of X75HD units available for control on the same subnet.
Page 100: Configuring For Http Control (Via Web Browser)

Page 103: Configuration Exceptions And Further Information
Mutually Exclusive Inputs Several input settings are mutually exclusive. For example, the back of the X75HD allows for up to three HD input sources; however, only one of these inputs sources can be accepted at a time. In this example, all output groups must be set to the same HD input type, not to three different input types.
Page 104 There are more advanced settings and configuration types outside of the M-Path menu. Advanced configurations are found within System Setup > Factory > Advanced Routing. However, Leitch advises that you do not attempt make advanced configurations prior to contacting your customer service representative. Any changes made in the Advance Routing menu will override manual settings made previously.
Page 105: Configuring Video
When multiple video sources are connected, the Video In Precedence setting determines the selection of the input video. For example, if the X75HD unit detects two input signals, it will accept the signal tagged as Higher over another lower-precedence signal. Found in the top-level Routing Setup menu, precedence levels include Highest, High, Normal, Low, and Lowest.
