How To Use The IRT

NTI AUDIO/HD VIDEO MATRIX SWITCH

The IRT-64X32 enables the user to control the connections of up to 32 input ports and 16 output ports on up to four (4) separate NTI video matrix switches. When any key is pressed, the IRT will power ON. A number key should always be pressed first unless a change to the configuration is desired (see "Set Configuration" on page 28). When a number key is pressed the LCD will display that number blinking. What to press next depends on what action is desired;

•change the switch to be controlled

•change the output port

•change the input port

Note: The user must always change or confirm the output port first and the input port second

If the "SYS", "IN" or "OUT" key is pressed first, the LCD will display the current switch followed by the decimal point and an error signal "EE". The error signal will display because there is no number to be displayed. A number key must always be pressed before a "SYS", "IN" or "OUT" key is pressed.

Exception: The "SYS" key is pressed first when setting the configuration. (See page 28)

Power ON with SYS, IN or OUT keys

Power ON with "2" key

Change the Switch

Press the number of the switch to be controlled. The number selected will be blinking in the last digit.

FYI: If the user realizes that an invalid number has been introduced before pressing either the "SYS", "IN", or "OUT" buttons, a correction can be made by pressing the correct number. If the correct number is a single digit, it must be preceded by a "0" to make the correction.

Press the "SYS" key. The blinking number will become blank and the switch number will update.

Note: If the number entered is larger than 4, when the "SYS" key is pressed the LCD will display the current switch and the error signal "EE".
