The LEDs on the ServSwitch™ Brand 8 x 2 Matrix Video Switch's rear panel,

shown in Figure 3-1 at the start of Chapter 3, indicate which of the Switch's outputs

are displaying the video from which inputs, and which outputs have been blanked

and aren't showing anything (see Section 4.3).

There are two rows of eight LEDs, labeled "Channel" and "1" through "8." The

top row shows which input is selected for "OUT A," while the bottom row shows

which input is selected for "OUT B." If no LEDs are lit in an output port's row, the

output has been blanked and the keypad is in test mode (see Section 4.3)

In a single-head video system: To switch your output port's monitor or other

destination device to display a given input, press the number of that input on your

keypad. For example, to display the video from a CPU attached to INPUT 8, press

the "8" button. The LED next to that button will light (and will stay lit until a

different port is selected).

In a dual-head video system: To switch the output-port monitors or other pair of

destination devices to display a given pair of inputs, press the number of the lower-

numbered input on your keypad (which must be connected to the Switch's

"KEYPAD A" port). For example, to display the video from a CPU attached to

INPUT 3 and INPUT 7, press the "3" button. The LED next to that button will

light (and will stay lit until a different port is selected). Buttons #5 through #8 have

no function.

In either single- or dual-head systems: Buttons 9 and 10 on the keypad have no

switching function; pressing them will have no effect unless you press both at the

same time, which will blank the output and trigger the keypad's self-test function

(see Section 4.4).

If you use both a keypad and a serial device (see Section 4.3) to control the

Switch, keep in mind that the serial device can switch both outputs, so your display

might sometimes switch to a different input without your pressing any buttons on

the keypad. If this happens, you can check the keypad's LEDs to see which input is

now being displayed.
