• MEMORY Assign Of the sixteen memories specified in the MEMORY screen, any four can be assigned to the front panel MEMORY [A]-[D] buttons. When you click the name shown beside each button [A]-[D], a list of the assignable memories will appear. Select the memory that you want to assign to each button [A]-[D]. When you click a button [A]-[D], the memory assigned to that button will be recalled and the parameter settings will be switched accordingly. This is the same function as the IMX644's MEMORY [A]-[D] buttons. NOTE • You may assign the same memory to more than one button. If you select a button to which the same memory has been assigned, one button in the priority order of [A]-[D] will be selected. If you want to recall memories while connected online with the IMX644, use the [A]-[D] buttons in IMX644 Manager; not the IMX644's MEMORY [A]-[D] buttons. GPI screen Here you can specify the memory that will be recalled for each input port of the GPI connector, and the open/closed status for each output port. NOTE • The GPI connector is a D-sub 25-pin connector for GPI (General Purpose Interface), used to input and output control signals. The IMX644 has eight input ports and eight output ports, plus a dedicated output that indicates the unit's power-on/off status. • For details on the GPI connector's specifications and example circuits, refer to the IMX644 Owner's manual. • GPI Input Terminal Applying an appropriate input to one of the rear-panel GPI input ports recalls the assigned memory. For each input port, you can specify the memory that will be recalled. By default, memories 1-8 are assigned to input ports 1-8. If you want to change these assignments, click the Memory field of each input port and select the desired memory from the list that appears. Select [NONE] if you don't want to make an assignment. • GPI Output Terminal Here you can specify the open/closed status of each output port for each memory. This allows you to change the open/closed status of the GPI connector's output ports by recalling a memory. By default, all buttons are off (gray); i.e., open. If you click a button to turn it on (green), that output port will change to the closed state. Click a name field to access the "Name of GPI OUT" dialog box, where you can edit the name of the output port. IMX644 Manager Owner's Manual 30
