Reading the LED status
indicators
Reading the front
access model front
panel display
When you are switching channels with the keyboard or using the KeyScan
feature, you must first place your system in Command Mode. As long as you
are operating in Command Mode, whatever you type will be intercepted by
your XP4000 Series unit until the Enter or the Escape key is pressed to end
Command Mode. None of the keystrokes entered will be forwarded to the
attached computer. While you are in Command Mode, the Num Lock, Caps
Lock and Scroll Lock lights on your keyboard will blink or "Command Line"
will appear on your monitor until you press enter or escape. For more
information on placing your system in Command Mode, see the "Keyboard
Control" section next in this chapter.
If you are using a rear access model of an XP4000 Series unit, you will notice 2
LEDs above each channel letter on the front of your unit: one amber and one green.
These lights, when representing the status of transmitter or receiver boards, are
normally both on. This indicates that the boards and expansion cables have been
properly installed. Error conditions which would cause these indicators to either
blink or go out are shown in the table below. Note that if you are using a front access
model, you will only have the green status LED. This LED will be lit if either Port
1 or Port 2 is installed correctly.
Board Standard
Transmitter ON
Receiver ON
If you are using a front access model, you will have an alphanumeric display on
the front panel of the unit. This display reflects the active channel for the local
user console. For units with an address between 1 and 9, the display will show
the unit address and the channel. For units with addresses higher than 9, the
display will show an asterisk (*) in place of a unit address. For example, if
channel G in Unit 7 is the current active channel at the local console, the display
would show 7G. If channel K in Unit 12 is active, it would show *K.
