Set Configuration

NTI AUDIO/HD VIDEO MATRIX SWITCH

The IRT-64x32 factory default setting is 32 inputs and 16 outputs. When the batteries are changed the setting will return to the default value. At the default setting the IRT has the ability control any matrix switch with up to 32 inputs and 16 outputs without changing the configuration. However, when controlling smaller switches without changing the configuration it is up to the user to press valid number(s). To avoid confusion, it is recommended to configure the IRT to communicate with the largest switch to be controlled.

To change the maximum number of inputs or outputs:

1.From power-down state (blank LCD) press and hold the "SYS" button for at least 3 seconds. The LCD will first display an error message but after 3 seconds the letter "c" will display:

2.Enter the number of inputs or outputs. As the digits are entered, they will be displayed and the last one entered will blink.

Note: Only the inputs OR the outputs may be configured each time the configuration function is used. To perform another configuration operation the user must start again at "Set Configuration" step 1.

3.Accept the choice by pressing the "IN" button for setting inputs, or the "OUT" button for setting the outputs. The LCD will not blink anymore and will display “i” (for inputs) or "o" (for outputs) and the number.

Notes:

-The maximum number of inputs and outputs that can be entered is 32 and 16 respectively. If the user introduces a number larger, the display will show an error signal ("c.EE") and the maximum number will remain at the last valid value configured.

-If more than one switch is being controlled, the IRT should be configured for the largest switch. It is up to the user to introduce valid numbers to the smaller switches when making selections.
