NTI AUDIO/HD VIDEO MATRIX SWITCH

Scan Mode

Scan Mode causes output ports (audio and video) to automatically switch from one audio and video input port to the next consecutive audio and video input port after a specified period of time (referred to as the dwell time). Audio and video port switching will continue indefinitely and no ports will be skipped, whether there are audio or video sources connected to them or not. If desired, the VEEMUX-A can be configured to skip the scanning of specific ports using the RS232 Command Protocol (page 10) or Telnet (page 14) .

Dwell time settings can be any value from 0 seconds (000) to 255 seconds. A setting of 000 seconds (the default setting) disables Scan Mode for that output port. If Scan Mode is disabled for a specific port number, then the video or audio to that output port number will only change as decided by the administrator.

Note: While Scan Mode is enabled, audio and video ports of the same number will switch together. Independent control of video and audio ports will be disabled. I.e., when video output 1 switches from input 1 to input 2, audio output 1 will also switch from input 1 to input 2.

To configure Scan Mode from the front panel LCD:

Press MENU, the following lines will be displayed:

1)Set Baud Rate

2)Set Unit Addr

Press MENU again, the following line will be displayed:

3)Set Scan Mode

Press 3 to select that menu item. The following request will be displayed:

Select Port

Select the output to be programmed using the numeric keys, then press ENTER. The display will show the current Dwell Time value for that output and ask for a new value.

Current Time: 16

New Time:

Using the numeric keys, enter a value between 0 and 255 and press ENTER. Leading zeros are allowed (000) but the number should not exceed 3 digits. The Scan Mode dwell setting value 0 will disable Scan Mode for that output port.

Scan Mode dwell time settings can also be configured through the RS232 Command Protocol (page 10), Telnet commands (page 14), or through the Web Interface (page 21).

NOTE: Scan Mode configuration settings can only be saved if they are assigned a memory location via the Keypad Control (page 8). Otherwise when the power is cycled to the VEEMUX-A, all Scan Mode settings will be erased.

TIP: If the Scan mode settings are stored as memory location 0, they will be loaded each time the VEEMUX-A is powered ON.
