Installing the RS-232 Controller

In order to use the RS-232 serial interface to attach a high-end controller (such as a PC) to the VM0404H, use a serial cable such as a modem cable. The end connecting to the VM0404H should have a 9-pin male connector. Connect this to the serial interface on the rear of the VM0404H. Refer to number 4 on the diagram on page 10.

Note: To configure the controller serial port, see page 12.

Source Device Selection

The VM0404H offers easy and flexible source and display device selection via the front panel pushbuttons, using the remote control, or through the RS-232 serial interface.

Manual Selection

To manually select an HDMI source for a display, press the pushbutton that corresponds to the port to which the display device is connected. Pressing the pushbutton will cycle through the four attached HDMI source devices via the display device.

Note: The Port LEDs light to indicate which source device is currently selected for each display.

Remote Control Selection

To select an HDMI source for a display with the remote control, press the numbered button that corresponds to the port to which the display device is connected.

Then, cycle through the source devices by pushing the Port Up and Port Down buttons on the remote control unit.

ŠPress the Port Up button to cycle forward through the HDMI source devices (A to B; B to C; C to D; D to A)

ŠPress the Port Down button to cycle backward through the HDMI source devices (A to D; D to C; C to B; B to A)

Note: Aim the remote control unit at the IR receiver located at the front panel of the VM0404H. For optimum performance, make sure there is a clear line-of-sight between the remote control unit and the IR receiver.
