Ross Video XPression GPO Control Overview CrossOver Setup The Hagstrom KE-USB36 is a 36 GPI to USB Keyboard Encoder that allows the CrossOver™ Multi-Definition Live Production Switcher to use GPI output triggers to control the XPression™ Sequencer through keyboard commands. Using the Hagstrom KEUSB36, any key found on a standard north american keyboard and mouse (including movement) can be generated with GPI outputs from CrossOver. This allows the use of Hotkeys on the XPression Sequencer to perform Reads, Advancements, Take Offline and even move the Item bar in the sequencer. Additional commands such as Clear Channel is available by enabling the Shift, Alt, and Ctrl commands that can be added as modifiers to the Keystroke on a GPI by GPI basis. GPI Output Control Setup 1.
