Query LED status
View LED status	E LC }	X5) ]	X5) is a 32-digit number, of
			which each digit represents the
			status of an LED on the MLC
			front panel.

On MLC 62 models, the LEDs are numbered as follows:				1	2
1 =Transmit red
2 = Transmit green					3	– 6
3-6 = Display text LEDs 1 through 4			DISPLAY
7 = Button row 1, first LED		7	ON	OFF	8
8 = Button row 1, second LED
			VOLUME
9-12 = Volume text LEDs 1 through 4		13 – 17			9	– 12
13-17 = Volume LEDs 1 through 5		18			19
18	= Button row 2, first LED
19	= Button row 2, second LED	20	PC 21VIDEO		22
20	= Button row 3, first LED
21	= Button row 3, second LED
22	= Button row 3, third LED	23	LAPTOP	MUTE	25
23	= Button row 4, first LED		Extron
24	= Button row 4, second LED
25	= Button row 4, third LED		24
26-32 = Not used (Their status is always 0)

In X5), the LEDs are represented in descending order from 32 to 1; that is, the first digit represents LED 32, the second digit represents LED 31, and so on. The last digit represents LED 1. Each digit in X5) can be 0 through 4, representing the following possible LED statuses:

0 = off

1 = dim

2 = on (bright)

3 = slow blink

4 = fast blink

NOTE: Dual sized buttons, such as the input buttons on the MLC 62 IR D, each take up an entire button row and have

three LEDs apiece.

(This example is illustrated in the diagram below.)

In this LED status number, for example, the first digit on the right (LED 1) represents the red Transmit LED. Its status is 4, which indicates that it is blinking rapidly. The LEDs behind the display text (3 through 6) have a status of 1, which means they are dimly lit.

In this MLC 64 example, the red Transmit LED shows status 3 (blinking slowly). The LEDs behind the Display text show status 1 (dimly lit). LEDs 9, 10, and 11 show status 2 (brightly lit) because the PC button (row 2) is active.
